This article describes maritime archaeology in the northern Gulf of Mexico. The first explorations of the Gulf was undertaken in the sixteenth century. The ability to conduct archaeological work in this region is hindered by many environmental factors. The coastal topography is often shallow, necessitating the use of smaller vessels for easy bay and riverine entry. High-visibility dives environments in some areas of the Gulf facilitate discovery and recordation of wreck sites. Government involvement and intervention has led to the protection of some archaeological sites. Remote sensing surveys have identified some of the oldest shipwrecks in the gulf in the North American region. This article summarizes this area's specific shipwreck sites and emphasizes historical events that relate to archaeological discoveries through case studies. Improved data-collection techniques and public outreach can aid in discovering and protecting the Gulf's maritime cultural resources.

ABSTRACTThe black-capped petrel (Pterodroma hasitata) is an endangered seabird endemic to the western north Atlantic. Although estimated at ~ 1,000 breeding pairs, only ~ 100 nests have been located at two sites in Haiti and three sites in the Dominican Republic. At sea, the species primarily occupies waters of the western Gulf Stream in the Atlantic and the Caribbean Sea. Due to limited data, there is currently not a consensus on the marine range of the species. There are several maps in use for the marine range of the species and these differ with respect to the north, south, and eastward extent of the range. None of these maps, however, includes the Gulf of Mexico. Here, we report on observations of black-capped petrels during two vessel-based survey efforts throughout the northern Gulf of Mexico from July 2010 - July 2011, and from April 2017 - September 2019. During the 558 days and 54.7 km of surveys from both efforts we tallied 40 black-capped petrels. Most observations occurred in the eastern Gulf, although birds were observed over much of the east-west and north-south footprint of the survey area. Predictive models indicated that habitat suitability for black-capped petrels was highest in areas associated with dynamic waters of the Loop Current, similar to habitat used along the western edge of the Gulf Stream in the western north Atlantic. We suggest that the range for black-capped petrels be modified to include the entire northern Gulf of Mexico although distribution may be more clumped in the eastern Gulf and patchier elsewhere. It remains unclear, however, which nesting areas are linked to the Gulf of Mexico.

Abundance And Diversity

Meiobenthic nematode assemblages were examined at 16 stations along two transects on the eastern and western boundaries of the deep northern Gulf of Mexico (dNGOM) at depths of 212–3000 m. The highest abundance (297 individuals 10 cm−2) and number of genera (71) occurred at stations near the Mississippi River delta. Number of genera decreased with increasing depth, and showed differences in community composition between the east and west regions. The dominant family, Comesomatidae, was represented by Sabatieria that was present at most shallow stations but absent at greater water depths. A significant difference in nematode feeding morphology was observed between depth groups but not between the two transects at different longitudes. Patterns of nematode community structure are congruent with harpacticoid copepods. Overall, the higher abundance and diversity of nematodes in the north-central Gulf of Mexico is consistent with findings of other benthic taxa and reflects organic material loading from the Mississippi River driving deep sea communities in the Gulf. The east-west gradient in composition of nematode communities suggests that nematode assemblages have well-defined distribution patterns similar to other meiobenthic taxa in the GOM but they are not aligned in the bathymetric zones observed in macrofauna, megafauna and demersal fishes.

Gray and Pape, Inc., performed an intensive pedestrian cultural resources survey of the Area of Potential Effects of permitted segments of proposed pipeline refurbishment located in Midland and Mitchell Counties, Texas. To date, no federal permitting has been identified for the project. However, approximately 3.2 kilometers (2 miles) of the project area are located on lands owned by the City of Midland and the City of Colorado City, and will be reviewed under the Texas Antiquities Code (Texas Natural Resource Code, Title 9, Chapter 191), Permit number 8677. The area surveyed amounts to approximately 20 hectares (50 acres) of survey corridor, which is considered the Area of Potential Effects. A records and literature review of the project location prior to survey identified two previously recorded archaeological sites and two previously conducted surveys within a 1.6-kilometer (1-mile) radius of the project. Fieldwork was conducted in January and March of 2019. The project required 156-person hours to complete and involved archaeological reconnaissance and shovel testing throughout the entire Area of Potential Effects. A total of 116 shovel tests were excavated along current and previously planned routes, of which 10 were positive for cultural materials. One new previously unrecorded site was identified as a result of survey. Site 41MD58 consists of a low-density surface and buried lithic scatter of a limited number of artifacts and artifact types. The surface of the resource area showed clear disturbance from the adjacent pipeline right-of-way and agricultural activities. A portion of the site was in the process of being disturbed at the time of site delineation by pipeline activities unrelated to the current project consisting of an open trench and associated spoil. Shovel tests within the site showed a lack of integrity primarily as a result of natural and artificial processes resulting in the dispersion of artifacts. The site did not contain temporally or culturally diagnostic artifacts and no artifacts were collected. Nor were any cultural features or historic-age standing resources encountered in the field. Based on the paucity of artifacts, lack of diagnostic materials, and lack of integrity, the site portion located within the Area of Potential Effects is recommended not eligible for State Antiquities Landmark or National Register status. Gray & Pape, Inc. recommends no additional archaeological work for the site or surveyed portions of the project detailed in this report. However, Gray & Pape, Inc. recommends that an unanticipated discoveries plan be put into place in the event that discoveries take place during construction. Gray & Pape, Inc. submitted project records to the Center of Archaeological Studies at Texas State University.
