Gulf South Research Corporation (GSRC) personnel conducted an intensive archaeological survey of an existing footpath and detached river terrace, referred to as “No Name Island” proposed for vegetation removal on behalf of U.S. Customs and Border Protection (CBP). The project area consists of an approximately 0.25-mile-long dirt footpath, which is proposed to be widened to 16 feet to allow vehicle access (i.e., No Name Access Road), and an approximately 1.12-acre area of detached river terrace (i.e., No Name Island), for which clearing of dense vegetation is proposed. This investigation constitutes CBP’s good faith effort to take into account any adverse effects that may occur as a result of the proposed undertaking in compliance with Section 106 of the National Historic Protection Act (NHPA) (Public Law 89-665; 54 U.S.C. 300101 et seq). The intensive Phase I archaeological investigation included background research of the physical environment, cultural history of the area, previous investigations and previously reported cultural resources, and field survey. Field survey included pedestrian surface inspection supplemented with the excavation of shovel test pits (STPs). Background research revealed eight investigations have been previously conducted, three archaeological sites, and one National Register of Historic Places (NRHP)-listed historic district have been previously recorded within a 0.5-mile radius of the proposed project area. Two of these investigations overlapped with portions of the survey area. None of the previously identified archaeological sites or the NRHP-listed district overlap with either the No Name Access Road or No Name Island survey areas. During field survey, the pedestrian survey encountered no archaeological resources on the ground surface. The subsurface testing consisted of the excavation of four STPs along No Name Access Road within the 0.25 mile long, 60-foot wide project corridor and five STPs within the 1.12 acre No Name Island vegetation removal area. None of the nine STPs were positive for cultural material. As a result of this investigation, no cultural resources were identified within the proposed project area. The proposed project will have no adverse effect on cultural resources and no further work is recommended.

On behalf of VRRSP Consultants, LLC and Central Texas Regional Water Supply Corporation (CTRWSC), SWCA Environmental Consultants (SWCA) conducted cultural resources investigations of the Vista Ridge Regional Water Supply (Vista Ridge) Project in Burleson, Lee, Bastrop, Caldwell, Guadalupe, Comal, and Bexar Counties. The work will involve installation of a 139.45-mile-long, 60-inch-diameter water pipeline from northcentral San Antonio, Bexar County, Texas, to Deanville, Burleson County, Texas. The report details the findings of investigations from June 2015 to December 2015, on the alignment dated December 8, 2015 (December 8th). The Vista Ridge Project is subject to review under Section 106 of the National Historic Preservation Act (54 USC 306108) and its implementing regulations (36 CFR 800), in anticipation of a Nationwide Permit 12 from the U.S. Army Corps of Engineers in accordance with Section 404 of the Clean Water Act. In addition, the work is subject to compliance with the Antiquities Code of Texas under Permit Number 7295, as the Vista Ridge Project will be ultimately owned by a political subdivision of the State of Texas. The cultural resources investigations included a background review and intensive field survey. The background review identified previous investigations, recorded archaeological sites, National Register of Historic Places (NRHP) properties, cemeteries, standing structures, and other known cultural resources within a 0.50-mile radius of the project area. The field investigations conducted from June 2015 through December 2015 assessed all accessible portions of the proposed December 8th alignment as of December 25, 2015. Approximately 101.8 miles of the 139.45-mile alignment has been surveyed. Approximately 24.42 miles were not surveyed based on the results of the background review and extensive disturbances as confirmed by vehicular survey. The remaining 13.23 miles that require survey were either unavailable due to landowner restrictions or part of a newly adopted reroute. SWCA also surveyed additional mileage, which includes rerouted areas that are no longer part of the December 8th alignment. The inventory identified 59 cultural resources, including 52 archaeological sites and seven isolated finds. In addition to newly recorded resources, two previously recorded archaeological sites were revisited, and two cemeteries were documented. Of the 52 newly recorded archaeological sites, seven are recommended for further work or avoidance. Of the two revisited archeological sites, one is recommended for further work or avoidance within the project area. Avoidance is recommended for both documented cemeteries. The resources with undetermined eligibility require additional testing or other avenues of research before SWCA can make a firm recommendation about their eligibility for nomination to the NRHP and designation as State Antiquities Landmarks (SALs). As part of a management strategy, the resources with undetermined eligibility may also be avoided by reroute or boring beneath. The remaining 45 cultural resources are recommended not eligible for inclusion to the NRHP or for designation as SALs and no further cultural resources investigations or avoidance strategies are recommended.

Trail Development

Over several mobilizations between April 2018 and January 2020, Gray & Pape, Inc., of Houston, Texas, conducted an intensive pedestrian cultural resources survey of two segments (Segments GR02 and GR03) of proposed trail development along Lower Greens Bayou in the City of Houston, Harris County, Texas. The project alignment measures approximately 10.8 kilometers (6.7 miles) in length and encompasses approximately 9.6 hectares (23.7 acres) of area. Another 0.6 kilometers (0.4 miles) or 0.6 hectares (1.4 acres) of project alignment was removed from consideration. In total, approximately 11.4 kilometers (7.1 miles) or 10.2 hectares (25.1 acres) was surveyed for the project. Because the proposed trail development occurs on publicly owned properties a Texas Antiquities Code Permit was required prior to survey. All work was completed under Texas Antiquities Permit #8328, which was assigned by the Texas Historical Commission on February 14, 2018. Fieldwork and reporting activities were performed according to procedures set forth by the Texas Historical Commission and the Council of Texas Archeologists. The goals of the survey were to establish whether or not previously unidentified archaeological resources were located within the project area, also defined as the project’s Area of Potential Effects, and whether the proposed development would affect any previously identified cultural resources. Prior to fieldwork, site file and background research was conducted, including a review of historic aerial and topographic maps in an attempt to locate any historic structures associated with the Area of Potential Effects. Site file review and background research indicated that there are no previously recorded sites within the project Area of Potential Effects. Fieldwork took place between April 10, 2018 and January 7, 2020 and consisted of a combination of pedestrian survey and shovel testing. Systematic shovel testing was performed along a single transect over both project segments resulting in 131 shovel tests being excavated, of which 11 were positive for cultural material. The survey revealed that large portions of both project segments have been heavily disturbed by development and flood events, however, three new archaeological sites, 41HR1234, 41HR1235, and 41HR1236, and one historic Isolate were identified as a result of survey. Site 41HR1234 was identified as a mid-twentieth century historic trash midden. Site 41HR1235 was identified as a Late Prehistoric ephemeral campsite. Site 41HR1236 was identified as a multicomponent prehistoric campsite and historic isolate. Diagnostic artifacts were observed at all three sites; however, it is the recommendation of Gray & Pape, Inc. that only Sites 41HR1235 and 41HR1236 are significant in the materials they contain and their potential to offer additional research potential. Direct impacts to both sites have been avoided by the project alignment as currently planned. While indirect impacts such as looting are a concern, the distance between the sites and the current alignment as well the density of woods surrounding them minimizes the danger as a result of the project. Eligibility testing is recommended for the sites if they cannot be avoided by future projects. Based on the results of this survey, Gray & Pape, Inc. recommends that the no further cultural resources work be required for the project as currently planned and that the project be cleared to proceed. As specified under the conditions of Texas Antiquities Code Permit #8328, all project associated records are curated with the Center of Archaeological Studies at Texas State University in San Marcos, Texas.

SWCA Environmental Consultants (SWCA) was retained by CrownQuest Operating, LLC, to complete an intensive cultural resources investigation for the proposed CrownQuest City of Midland Oil and Gas Project (Project). The Project includes newly proposed oil and gas well pads, crude oil pipeline, and associated access roads on City of Midland property in Midland and Glasscock Counties, Texas. These new components will be constructed within an existing upstream oil and gas system. The 149.9-acre (60.7-hectare) Project area is located approximately 15 miles southeast of Midland, Texas, immediately south of Highway 158, and is situated along and between Johnson and Pemberton Draws. The Project involves a political subdivision within the state of Texas (City of Midland). The Antiquities Code of Texas (ACT) applies because the Project’s activities occur on property owned by the City of Midland and will involve more than 5 acres / 5,000 cubic yards of land disturbance or may potentially affect known archaeological sites. It is SWCA’s understanding that the Project does not currently have a federal nexus, and it is not subject to Section 106 of the National Historic Preservation Act. The purpose of this investigation was to identify and assess any cultural resources, such as historic and prehistoric archaeological sites and historic buildings, structures, objects, and sites (such as cemeteries) that might be located within the boundaries of the proposed Project and evaluate their significance and eligibility for designation as a State Antiquities Landmark. The investigations included a background and historic map review of the Project area and immediately surrounding region followed by pedestrian survey with visual examination and shovel test excavations at proposed Project activity areas. All investigations were conducted in accordance with the ACT and standards and guidelines established by the THC and Council of Texas Archeologists. Following the review and acceptance of the final cultural resources report, all records and photographs will be curated with the Center for Archaeological Research at the University of Texas at San Antonio, per requirements of the ACT in accordance with the CTA guidelines. The cultural resources investigation was conducted under ACT Permit No. 8506. Fieldwork was performed from July 30 to August 4, 2018. The Project setting was mainly eroded and heavily disturbed uplands with occasional exposures of bedrock and caliche. Pedestrian survey was augmented by hand excavating 253 shovel tests and seven auger tests, which were terminated at the maximum reachable depth or at soils likely predating human occupation, typically around 45 cm below surface. The most pervasive land disturbance observed was related to petroleum exploration and extraction activities that have generally impacted ground surface integrity. During the investigation SWCA archaeologists did not observe any prehistoric or historic cultural resources within the Project area. The location near site 41MD4, identified during the background review, could not be visited by SWCA survey staff due to a fire in the facility. The site boundary defined does not extend into a proposed Project activity area and the closest associated Project item is already disturbed. On that basis it is not considered to be a Project concern. Based on the negative findings of the intensive cultural resources survey, SWCA recommends that no further archaeological investigations are warranted within the assessed portions of the CrownQuest City of Midland Oil and Gas Project area.

Gray & Pape, Inc., of Houston, Texas, under contract with BIO-WEST, Inc., has prepared the following report on cultural resources management activities in Fort Bend County, Texas. The project includes an archaeological survey of a total of approximately 0.93 kilometers (0.58 miles) along Buffalo Bayou between Katy-Flewellen Road and Kingsland Boulevard in Katy, Texas. The archaeological Area of Potential Effects is defined as the maintenance corridor, 30 to 60 meters (98 to 196 feet) long. The goal of this study was to assist Fort Bend County, the Texas Historical Commission, and the lead federal agency in determining whether or not intact cultural resources are present within areas for construction, and if so to provide management recommendations for these resources. All activities described herein were subject to Section 106 of the National Historic Preservation Act and issuance of an Antiquities Permit for Archeology (Permit 9319) applied for by Gray & Pape, Inc. on February 13, 2020, and issued by the Texas Historical Commission. No diagnostic or non-diagnostic artifacts were collected in the course of the current survey. As a project permitted through the Texas Historical Commission; however, Gray & Pape, Inc. submitted project records to the Center of Archaeological Studies at Texas State University. The Natural Resource Conservation Service is the lead federal agency for the project. Fieldwork was conducted between March 12 and March 16, 2020 and required approximately 40person hours to complete. Subsurface testing included a combination of systematic shovel testing and judgement sample auger probing. The site file research revealed two previously recorded archaeological sites (41FB101 and 41FB102) are located within the project area. At the beginning of the survey, an initial attempt was made to relocate previously recorded Sites 41FB101 and 41FB102 through surface inspection and limited shovel testing across the Area of Potential Effects along both sides of Buffalo Bayou. Recent disturbances from mechanical excavation along the channel slopes, the dumping of spoil across the surface of the two-track right-of-way along the bayou, and the active installation of sheet piling were photographed and mapped. Sites 41FB101 and 41FB102 could not be relocated within the Area of Potential Effects during the surface inspection, shovel testing or auger probing. No other historic or prehistoric artifacts or cultural features were identified as a result of this survey. During the initial reconnaissance, Rangia shells (n=8), including whole (closed) specimens and half shell, were observed on the surface in an area recently disturbed by heavy machinery. The shells were located east of Site 41FB101 along the two-track right-of-way and slope of the east bank of Buffalo Bayou. The majority of them were smaller than 3 centimeters (1.2 inches), with one whole specimen measuring approximately 6 centimeters (2.4 inches). Surface and subsurface inspection in the immediate area of these specimens failed to find evidence of associated cultural features or artifacts on the surface or in a buried context. A variety of modern bricks and brick fragments were also observed along the inner slopes of the east bank near the shell scatter. These same materials were later observed among the variety of riprap materials along the west bank of the bayou west of Site 41FB102 near a residential property immediately adjacent to the Area of Potential Effects. No additional cultural materials were observed on the surface with the exception of modern debris including plastics and aluminum cans. Gray & Pape, Inc. is not recommending a site designation for the Rangia shell or brick scatter observed during the survey for the foregoing reasons:1) there were no intact, buried deposits or features found; 2) there was no material that could be positively identified as artifacts; 3) the bricks observed were modern and likely deposited by landowners in attempts to prevent erosion; 4) the size, quantity, and inclusion of whole Rangia identified on the surface appear to be natural occurrences as opposed to the remains of an archaeological deposit or feature; and 5) it is impossible to determine the original location of the shell specimens at this time. Based on the results of this investigation, Sites 41FB101 and 41FB102 do not appear to extend into the existing easement belonging to the Fort Bend County Drainage District. Instead, both sites appear to be located on private property outside of the project Area of Potential Effects. As such, these sites have not been evaluated for National Register eligibility, but Gray & Pape, Inc. recommends that there will be no direct impact to these sites. It is also recommended that because the majority of project impacts will occur within sediments that have been repeatedly impacted by past channelization activities, the potential to identify intact, significant cultural resources is low. Gray & Pape, Inc. recommends the project be allowed to proceed as currently planned. As a protective measure during construction, high-visibility temporary fencing should be installed against the edge of the Area of Potential Effects in the vicinity of the two known sites. No additional cultural resources activities are recommended unless project plans change.

On behalf of Ecology and Environment, Inc. (E & E), Rio Grande LNG, LLC, and Rio Bravo Pipeline Company, LLC (RB Pipeline), SWCA Environmental Consultants (SWCA) conducted cultural resources surveys of portions of the Rio Bravo Pipeline on lands owned or controlled by the Port of Brownsville in Cameron County, Texas. Rio Grande LNG, LLC proposes to construct a natural gas liquefaction facility and liquefied natural gas (LNG) export terminal (Terminal) in Cameron County, Texas, along the north embankment of the Brownsville Ship Channel. In concert with the Terminal, RB Pipeline proposes to construct an associated pipeline system (Pipeline System/Project) within Cameron, Willacy, Kenedy, Kleberg, and Jim Wells Counties, Texas to allow for interconnection with a network of existing pipelines that traverse the northern end of Kleberg County and Jim Wells County. The proposed Pipeline System/Project will collect and transport natural gas to the Terminal site. In compliance with the Federal Energy Regulatory Commission and U.S. Army Corps of Engineers permitting requirements and oversight, SWCA conducted cultural resources investigations in compliance with Section 106 of the National Historic Preservation Act (NHPA) (54 U.S.C. 306108) and its implementing regulations in 36 Code of Federal Regulations 800. Although the entire Project is subject to compliance with Section 106 of the NHPA, this stand-alone report specifically addresses portions of the alignment that will be located on lands owned by the Port of Brownsville (Port). Since the Port is a political subdivision of the state, investigations were conducted in compliance with the Antiquities Code of Texas (ACT) under ACT Permit No. 8588 administered by the Texas Historical Commission (THC). The data in this report is also presented in Addendum IV (Carpenter et al., 2020) to the final report (Nielsen et al., 2016) of the overall investigations. The investigations covered 0.58 mile (0.93 kilometers [km]) of proposed pipeline corridor within a 200-foot-wide (60.96-meter [m]-wide) pipeline survey corridor, and 0.31 mile (0.50 km) of proposed access roads within a 50-foot-wide (15.24-m-wide) access roads survey corridor, for a Project Area total of approximately 15.8 acres within Port property. The cultural resources investigations included a background and historical map review, and an intensive pedestrian survey with subsurface testing. The background review identified nine previously conducted archaeological surveys within a 1-mile radius of the Project Area, three of which intersect the current Project Area. The background review identified no previously recorded archaeological sites within the Project Area; however, seven archaeological sites are within a 1-mile radius none of which are immediately adjacent (within 300 feet [91.44 m]) to the Project Area. In addition, a review of historical maps determined that there are no historic-age structures or features mapped within or immediately adjacent to the Project Area. SWCA archaeologists conducted the cultural resources intensive pedestrian survey on October 22, 2018. The investigation revealed an extensively disturbed setting due to historic & modern development in the area mainly associated with the Port. SWCA archaeologists excavated a total of nine shovel tests within the Project Area all negative for cultural materials. No cultural materials or features or historic-age structures were identified within the Project Area during the field survey. In accordance with the ACT and Section 106 of the NHPA, SWCA has made a reasonable and good faith effort to identify cultural resources within the Project Area of Potential Effects (APE). No cultural resources were identified within the Project Area during the current investigations. Accordingly, no further investigation is recommended for the assessed sections of the Project Area. The THC concurred with these findings and recommendations on January 14, 2020. No artifacts were recovered; documentation will be curated at the Texas Archeological Research Laboratory of The University of Texas at Austin.

Under contract to BIO-WEST, Inc., Gray & Pape, Inc., of Houston, Texas, conducted a Phase I marine archaeological survey for the proposed Webster to Seadrift Pipeline Project in Calhoun and Jackson counties, Texas. Enterprise Products Operating LLC sponsored the archaeological survey. All marine fieldwork and reporting activities were completed with reference to state law (Antiquities Code of Texas [Title 9, Chapter 191 of the Texas Natural Resources Code] and Texas State rules found in the Texas Administrative Code [Title 13, part 2, Chapters 26 and 28]) for cultural resources investigations. Work was completed under Texas Antiquities Permit Number 9004. The United States Army Corps of Engineers, Galveston District has been identified as the lead federal agency. All project records are curated at the Center for Archaeological Studies at Texas State University in San Marcos, Texas. The Phase I underwater archaeological investigation assessed the number, locations, cultural affiliations, components, spatial distribution, data potential, and other salient characteristics of potential submerged cultural resources within the proposed project area. The linear project area includes approximately 391 hectares (967 acres) of submerged land in Calhoun and Jackson counties, Texas. The investigation included a comprehensive magnetic and acoustic remote sensing survey and target analysis designed to determine the presence or absence of potentially significant remote sensing targets that might be affected by proposed project activity. Background research revealed that there are no previously recorded sites within the Area of Potential Effects and that there have been two previous cultural resource surveys (Pearson et al. 1993; Gearhart 2016), conducted between 1993 and 2016, partially within the project Area of Potential Effects. Research also revealed that the 50-meter (164-foot) avoidance areas, as mandated by Texas Administrative Code, Title 13, Part 2, Chapter 26, for three previously recorded magnetic anomalies (Mag 7–Mag 9) identified by Gearhart (2016) are partially located within the survey area. These three magnetic anomalies were recommended for avoidance as they represent potential cultural resources. The grid for the remote sensing survey within the open waters of Lavaca Bay consisted of a total of 19 track lines (Lines 1–16, 18,19, 37, and 38) at 20-meter (65.6-foot) line spacing oriented parallel to an existing pipeline right-of-way. The remaining portions of the project area within Lavaca River and Catfish Bayou were surveyed at 20-meter (65.6-foot) line spacing (Lines 0, 17, 22–35, and 39–43) oriented perpendicular to the survey corridor. The marine field investigations consisted of a magnetometer and side-scanning sonar investigation of the proposed project area in safely navigable waters between July 29 and 30, 2019, and required approximately 60-person hours to complete. A total of 284.6 kilometers (176.9 linear survey miles) were transected utilizing the magnetometer and side-scan sonar. Comprehensive analysis of the magnetic and acoustic data recorded for this project resulted in the identification of 127 discrete magnetic anomalies, with 80 meeting or exceeding the Pearson and Linden (2014) 50-gamma/65-foot criteria. A total of 43 of the 80 anomalies that meet or exceed the 50-gamma/65-foot criteria are associated with existing pipelines. While the remaining 37 anomalies, consisting of 22 magnetic targets, meet and/or exceed the 50-gamma/65-foot criteria, they do not meet Gearhart’s 2011 magnetic orientation and spatial criteria to be considered potentially significant. They are interpreted as relic oils wells, ferrous debris scatters associated with the oil and natural gas industries and recreational and commercial fishing activities, and miscellaneous debris from previous tropical storms and hurricanes. Review of the sonar record revealed two distinct acoustic targets (SST-1 and SST-2) consisting of the remnants of a subsequent exploratory oil well and a subsided pipeline trench. Based on the applied criteria, these magnetic and acoustic targets do not exhibit any characteristics associated with historic shipwrecks and/or other significant submerged cultural resources. As such, the recommended management action for magnetic targets, Numbers 1–22, as well as acoustic targets, SST-1 and SST-2, is no further archaeological investigations. One magnetic target, Number 23, situated outside of the Area of Potential Effects, is associated with previously recorded anomaly Mag 8, which was deemed as potential historic shipwreck remains. While it is located outside of the Area of Potential Effects, it was recorded within the 50-meter (164 foot) avoidance buffer of previously recorded anomaly Mag 8. No magnetic signatures were recorded within the portion of the avoidance buffer that is within the Area of Potential Effects. The lack of any residual magnetic signatures of the anomaly within the Area of Potential Effects indicate that no portions of the ferrous source objects for Mag 8 extend into the current survey area or the construction footprint; and therefore, the submerged target or its avoidance buffer will not be impacted by the proposed activities. Additionally, no magnetic signatures associated with previously recorded anomalies Mag 7 and Mag 9 were identified in the 50-meter (164-foot) avoidance buffers within the Area of Potential Effects. The lack of any residual magnetic signatures of anomalies (Mag 7 and Mag 9) within the Area of Potential Effects indicate that no portions of the ferrous source objects for these two magnetic anomalies extend into the current survey area or the construction footprint; and therefore, the submerged targets or their avoidance buffers will not impacted by the proposed activities. The recommended management action for the portions of the 50-meter (164-foot) avoidance buffers for Mag 7, Mag 8, and Mag 9 that extend partially into the current survey area is avoidance from any bottom disturbing activities. If bottom disturbing activities within the buffer buffers cannot be avoided, additional marine archaeological investigations in the form of diver-ground-truthing will be required to determine the nature and historical significance of the source magnetic objects.

Bank Stabilization

This report summarizes the results of a cultural resources survey by Gray & Pape, Inc. of an approximately 14.8-hectare (36.6-acre) property in Fort Bend County, Texas, planned for a bank stabilization project on behalf of their client, Berg-Oliver Associates, Inc. The goals of the survey were to determine if the proposed project would affect any previously identified archaeological sites as defined by Section 106 of the National Historic Preservation Act of 1966, as amended (36 CFR 800), and to establish whether or not previously unidentified buried archaeological resources were located within the project’s Area of Potential Effect. Portions of the project are on property owned by Fort Bend County Municipal Utility District Number 121, political subdivisions of the state, as such, a Texas Antiquities Permit (Permit Number 8734) was required prior to the commencement of fieldwork. All fieldwork and reporting activities were completed with reference to state (the Antiquities Code of Texas) and federal guidelines. Prior to fieldwork mobilization, a background literature and site file search were conducted to identify the presence of recorded sites and previous cultural resource surveys within or near the project area. The search indicated that no previously identified archaeological sites, cemeteries, historic markers, or National Register properties are located within the project area. The same research identified that eight previous cultural resource surveys had been conducted within the study radius of the project area, one of which overlapped with the current project area. In addition, 14 previously recorded archaeological sites are located within the study radius, none of which are located within or immediately adjacent to the current project area. Field investigations were carried out in two mobilizations in January and December 2019 and consisted of a combination of pedestrian survey and subsurface testing, resulting in the excavation of 32 shovel tests. Five planned tests were left unexcavated due to inundation, and eight planned tests were left unexcavated due to significant surface disturbance. All shovel tests were negative for cultural resource material and no historic-age resources were identified during survey. After a revised scope of work was submitted to the Texas Historical Commission, investigation of deeply buried soils took place tandem with construction by regular monitoring of construction excavation. When the construction schedule allowed, traditional deep testing, by means of mechanical excavation, was carried out in five of six areas anticipated to have deep impacts from the proposed bank stabilization project. A total of 22 trenches were excavated. No buried features or deeply buried paleosols were encountered. Gray & Pape, Inc. archaeologists are of the opinion that the shovel test survey and deep testing completed within the Area of Potential Effects has adequately assessed the potential for surface and near surface intact, significant cultural resources, as well as determining the potential for deeply buried resources or paleosols. No artifacts or cultural features were encountered during the course of the survey, and no new archaeological sites were identified. No negative impacts on any previously identified sites are anticipated from the proposed project. Based on these results, Gray & Pape, Inc. recommends that no further cultural work be required and that the project be cleared to proceed as planned. As required under the provisions of Texas Antiquities Code Permit 8734, all project records are housed at the Center for Archaeological Studies at Texas State University, San Marcos, Texas.

Geophysical prospecting methods have been extensively used to outline buried antiquities in terrestrial sites. Despite the frequent application of these mapping and imaging approaches for the detection of archaeological relics in deep-water marine environments (e.g., shipwrecks), the aforementioned processes have minimal contribution when it comes to understanding the dynamics of the past in coastal and shallow aquatic archaeological sites. This work explores the possibilities of multicomponent geophysical techniques in revealing antiquities that have been submerged in diverse shallow coastal marine environments in the eastern Mediterranean. A group of four sites in Greece (Agioi Theodoroi, Olous, Lambayanna) and Cyprus (Pafos) spanning from prehistory to Roman times were chosen as test sites to validate the efficiency of electrical resistivity tomography, magnetic gradiometry, and ground penetrating radar methods. The comprehensive analysis of the geophysical data completed the picture for the hidden archeological elements in all the sites. The results manifest the significance and the potential of these methods for documenting and understanding the complex archaeological sites encountered in the Mediterranean. In view of climate change and the risks related to future sea level rise and erosion of low-level coastal areas, the results of this work could be integrated in a strategic framework to develop an effective interdisciplinary research model that can be applied to similar shallow water archaeological surveys, thus substantially contributing towards cultural resources management.

Archaeological wrecks exposed on the sea floor are mapped using side-scan and multibeam techniques, whereas the detection of submerged archaeological sites, such as Stone Age settlements, and wrecks, partially or wholly embedded in sea-floor sediments, requires the application of high-resolution subbottom profilers. This paper presents a strategy for cost-effective, large-scale mapping of previously undetected sediment-embedded sites and wrecks based on subbottom profiling with chirp systems. The mapping strategy described includes (a) definition of line spacing depending on the target; (b) interactive surveying, for example, immediate detailed investigation of potential archaeological anomalies on detection with a denser pattern of subbottom survey lines; (c) onboard interpretation during data acquisition; (d) recognition of nongeological anomalies. Consequently, this strategy differs from those employed in several detailed studies of known wreck sites and from the way in which geologists map the sea floor and the geological column beneath it. The strategy has been developed on the basis of extensive practical experience gained during the use of an off-the-shelf 2D chirp system and, given the present state of this technology, it appears well suited to large-scale maritime archaeological mapping.

Survey Results

Survei arkeologi sangat penting untuk penemuan dan interpretasi sisa-sisa yang ditinggalkan oleh aktivitas manusia prasejarah. Saat ini penginderaan jarak jauh dan model prediktif telah meningkatkan jangkauan dan keberhasilan survei arkeologi, namun survei pejalan kaki untuk mengembangkan parameter model dan prediksi kebenaran dasar masih penting untuk keberhasilan suatu penemuan. Penelitian ini merupakan hasil survei arkeologi tahun 2017 di Pulau Babar Besar dan Pulau Wetang yang termasuk dalam bagian dari kelompok Kepulauan Babar, Maluku Barat Daya, Indonesia. Tercatat sebanyak 62 situs arkeologi ditemukan di kedua pulau tersebut, tujuh diantaranya merupakan situs lukisan cadas baru yang ditemukan di Pulau Wetang. Hasil survei ini menunjukkan keberhasilan penggunaan peta geologi dan topografi di samping citra satelit dalam mendeteksi daerah prospektif untuk survei. Hasil penelitian ini juga menunjukkan bahwa pemahaman karakteristik geologi daerah yang lebih rinci dan komparatif diperlukan sebelum dilakukan survei jarak jauh yang lebih lanjut di wilayah Maluku Barat Daya, Indonesia.Archaeological surveys are essential to the discovery and interpretation of remains left by past human activities. While remote sensing and predictive models have greatly improved the reach and success of archaeological survey, pedestrian surveys to develop model parameters and ground-truth predictions is still imperative for successful discoveries. Here we present the results of the 2017 archaeological survey of islands Babar Besar and Wetang in the Babar Island Group, Maluku Barat Daya, Indonesia. A total of 62 archaeological sites were recorded between the two islands; seven of which represent new rock art sites on Wetang island. Our survey results indicate the successful use of geological and topographic maps alongside satellite images in detecting prospective regions for survey. Results also indicate however that a more detailed and comparative understanding of the regions geology is required before more advanced forms of remote survey are conducted in the Maluku Barat Daya region.
