Archaeology and its various branches (Prehistoric, Classical Antiquity, Mediaeval, Modern Era), as a part of the humanities, is a truly interdisciplinary science. Each of its dimensions is oriented towards the ways in which people have occupied spaces for thousands of years and the various forms of organisation this has taken. It can be said that archaeology operates in three dimensions. Apart from terrestrial archaeology, i.e. the usual field work, there is underwater archaeology (seas, lakes, watercourses) and also archaeology based on facts acquired from remote sensing, i.e. photos from space and the air. This paper focuses on this third dimension of archaeology, presenting examples of archaeological sites from the north of the Croatian archipelago, starting with Krk and continuing along the eastern Adriatic, including its hinterland, down to Pelješac (Ston).

Archaeological sites in Croatia's shallow waters are mentioned in written sources from the sixteenth century, and since the eighteenth century they have been used as evidence for the sinking of the Eastern Adriatic coast. It was at the end of the same century that the first Roman shipwreck in Croatian waters was reported. Sponge divers and coral hunters raised archaeological finds from the seabed off the Croatian coast, thus contributing to the creation of many private and monastic collections. Isolated campaigns aimed at protecting underwater cultural heritage began in the 1950s, and by 1970 these efforts became part of a well-organized system. Although the lack of systematic research remains notable, a number of surveys and rescue excavations have enriched our knowledge of ancient seafaring along the Croatian coast and have contributed to the study of the maritime environment. Some well-preserved shipwrecks from classical antiquity and the modern era show excellent potential for thein situprotection and presentation of Croatian underwater cultural heritage.

In August 2018, a group of experts working with terrestrial/marine geophysics and remote sensing methods to explore archaeological sites in Denmark, Finland, Norway, Scotland and Sweden gathered together for the first time at the Workshop ‘Sensing Archaeology in The North’. The goal was to exchange experiences, discuss challenges, and consider future directions for further developing these methods and strategies for their use in archaeology. After the event, this special journal issue was arranged to publish papers that are based on the workshop presentations, but also to incorporate work that is produced by other researchers in the field. This paper closes the special issue and further aims to provide current state-of-the-art for the methods represented by the workshop. Here, we introduce the aspects that inspired the organisation of the meeting, a summary of the 12 presentations and eight paper contributions, as well as a discussion about the main outcomes of the workshop roundtables, including the production of two searchable databases (online resources and equipment). We conclude with the position that the ‘North’, together with its unique cultural heritage and thriving research community, is at the forefront of good practice in the application and development of sensing methods in archaeological research and management. However, further method development is required, so we claim the support of funding bodies to back research efforts based on testing/experimental studies to: explore unknown survey environments and identify optimal survey conditions, as well as to monitor the preservation of archaeological remains, especially those that are at risk. It is demonstrated that remote sensing and geophysics not only have an important role in the safeguarding of archaeological sites from development and within prehistorical-historical research, but the methods can be especially useful in recording and monitoring the increased impact of climate change on sites in the North.

AbstractBathymetry maps derived with satellite-based multispectral sensors have been used extensively for environmental and engineering coastal studies and monitoring. However, so far this technique has not been widely exploited in other coastal applications, such as underwater archaeology. Submerged settlements and shipwrecks are often located in water depths where the application of multispectral satellite data is feasible. This could lead to more efficient field work practices thus enabling more optimal allocations of costs and labour during archaeological excavations. This study explores the contribution of processed satellite bathymetry maps to the recording of two archaeological coastal sites: a submerged prehistoric settlement in Greece and a shipwreck of a modern cargo vessel in Italy. The results indicate that even though the accuracy of satellite derived bathymetry is high, the level of detail (spatial resolution) is not sufficient to fully replace field-based measurements. However, the use of satellite data complements the existing techniques and can help to place the archaeological sites within a broader spatial context as well as to efficiently monitor the deterioration of a site due to natural causes or human activity, which inevitably leads to risk management. When the study of larger objects is involved (for example First World War shipwrecks) the potential of using satellite data in underwater archaeological studies becomes more promising.

Geology of Greenland Survey Bulletin, 186, 50-59. https://doi.org/10.34194/ggub.v186.5215 _______________ The southern tip of Greenland is underlain by the Palaeoproterozoic Ketilidian orogen (e.g. Chadwick & Garde 1996; Garde et al. 1998a). Field investigations in the summer of 1999 were focused on the structure of migmatites (metatexites) and garnetiferous granites (diatexites) of the Pelite Zone in the coastal region of South-East Greenland between Lindenow Fjord and Kap Farvel (Figs 1, 2). Here, we first address the tectonic evolution in the Pelite Zone in that region and its correlation with that in the Psammite Zone further north. Then, the structure and intrusive relationships of the rapakivi suite in the Pelite Zone are discussed, including particular reference to the interpretation of the controversial outcrop on Qernertoq (Figs 2, 8). Studies of the structure of the north-eastern part of the Julianehåb batholith around Qulleq were continued briefly from 1998 but are not addressed here (Fig. 1; Garde et al. 1999). The field study was keyed to an interpretation of the Ketilidian orogen as a whole, including controls of rates of thermal and tectonic processes in convergent settings. Earlier Survey field work (project SUPRASYD, 1992–1996) had as its principal target an evaluation of the economic potential of the orogen (Nielsen et al. 1993). Ensuing plate-tectonic studies were mainly funded in 1997–1998 by Danish research foundations and in 1999 by the Natural Environment Research Council, UK. The five-week programme in 1999 was seriously disrupted by bad weather, common in this part of Greenland, and our objectives were only just achieved. Telestation Prins Christian Sund was the base for our operations (Fig. 2), which were flown with a small helicopter (Hughes MD-500).

The article is devoted to the problem of using remote sensing data for studying and mapping archaeological sites in interdisciplinary research. The purpose of the experiments is to develop a methodology for searching and mapping archeological monuments based on the interpretation of aerospace images. The problem to be solved is formalized search and the procedure of selecting objects. The complex of tasks for ridentifying objects from images cannot be realated only to the field of decryption, it also deals with the field of information processing signals (computer vision), and this is where the great potential for continuing experiments is seen. In the process of implementing the tasks, the Detection Artefacts software package was developed, which is based on noise reduction, filtering, morphological analysis, binarization, etc. Its notable feature is the freedom of choice settings, the ability of setting parameters

Abstract Subsurface coherent vortices in the North Atlantic, whose saline water originates from the Mediterranean Sea and which are known as Mediterranean eddies (meddies), have been of particular interest to physical oceanographers since their discovery, especially for their salt and heat transport properties into the North Atlantic Ocean. Many studies in the past have been successful in observing and studying the typical properties of meddies by probing them with in situ techniques. The use of remote sensing techniques would offer a much cheaper and easier alternative for studying these phenomena, but only a few past studies have been able to study meddies by remote sensing, and a reliable method for observing them remotely remains elusive. This research presents a new way of locating and tracking meddies in the North Atlantic Ocean using satellite altimeter data. The method presented in this research makes use of ensemble empirical mode decomposition (EEMD) as a means to isolate the surface expressions of meddies on the ocean surface and separates them from any other surface constituents, allowing robust meddies to be consistently tracked by satellite. One such meddy is successfully tracked over a 6-month time period (2 November 2005 to 17 May 2006). Results of the satellite tracking method are verified using expendable bathythermographs (XBT).

Lusitanian Basin

Abstract At the beginning of the Alpine cycle, the breakup of Pangea lead to the early stages of the North Atlantic opening. In the western Iberian sector of the European margin, the Lusitanian basin starts to evolve bordered eastwards by inherited reliefs from the late episodes of the Variscan orogeny. The base unit, the Silves Group, considered not earlier than the Carnian, is mainly siliciclastic and predominantly formed by arcosarenites to feldspar litarenites, coarse to very coarse-grained (wackes) and pebbly, where the sediment architecture denotes organizations in continental (Conraria, Penela and Castelo Viegas Formations) environments. A first marine episode (Isocyprina Beds of Pereiros Fm.) marks a significant change within the sedimentary record; the uppermost part corresponds to intertidal transitional environments (sabkha). New and detailed field work of sedimentological and structural nature that has been carried out in recent exposures from the type-region of Coimbra-Penela enabled us to make significant observations and to improve data collection. This allowed a full reinterpretation of the paleotectonic and paleogeographical conditions under which the Silves Group and, consequently, the eastern border of the Lusitanian basin, evolved. This study carried out in the type-region also allowed a better understanding of its sequential organization. All units are unconformity bounded by strong influxes of coarse siliciclastics from the Iberian meseta. One of those unconformities (D2b) is an angular unconformity with cartographic expression. Tectonic reconstructions were possible to make after a detailed structural analysis of normal synsedimentary faults. Regional comparisons with Eastern Iberian basins that evolved since Permian times are also discussed. We conclude that the lower red siliciclastic units are older than has been considered until now. Those units were formed in a previous tensional stress pattern of tardi-Variscan affinities, related to megashear dextral kinematics of Permian-Triassic age. We propose that units below D2b unconformity can record a Proto-Lusitanian basin; the Lusitanian basin is younger and evolved mainly after the Triassic-Jurassic limit (Castelo Viegas Fm.) within an E-W extensional context related to Atlantic type basins.

Three dimensions for analyzing public sector pay administration are used to examine central government pay administration in Sweden and the United States of America. On the first dimension, market posture, both countries are found to fall short of their espoused policy, comparability. Greater consistency is found on the second dimension, social orientation, where both countries have pursued the goal of social equality. The equilization of salary levels across society is far greater in Sweden in keeping with the socialist objectives of wage solidarity. The third dimension, reward structure, shows the greatest distance between the two countries with the struggle to implement performance-contingent pay underway in the U.S. while Swedes continue to rely on longevity for pay increases.

Abstract The coupling of the land with the planetary boundary layer (PBL) on diurnal time scales is critical to regulating the strength of the connection between soil moisture and precipitation. To improve understanding of land–atmosphere (L–A) interactions, recent studies have focused on the development of diagnostics to quantify the strength and accuracy of the land–PBL coupling at the process level. In this paper, the authors apply a suite of local land–atmosphere coupling (LoCo) metrics to modern reanalysis (RA) products and observations during a 17-yr period over the U.S. southern Great Plains. Specifically, a range of diagnostics exploring the links between soil moisture, evaporation, PBL height, temperature, humidity, and precipitation is applied to the summertime monthly mean diurnal cycles of the North American Regional Reanalysis (NARR), Modern-Era Retrospective Analysis for Research and Applications (MERRA), and Climate Forecast System Reanalysis (CFSR). Results show that CFSR is the driest and MERRA the wettest of the three RAs in terms of overall surface–PBL coupling. When compared against observations, CFSR has a significant dry bias that impacts all components of the land–PBL system. CFSR and NARR are more similar in terms of PBL dynamics and response to dry and wet extremes, while MERRA is more constrained in terms of evaporation and PBL variability. Each RA has a unique land–PBL coupling that has implications for downstream impacts on the diurnal cycle of PBL evolution, clouds, convection, and precipitation as well as representation of extremes and drought. As a result, caution should be used when treating RAs as truth in terms of their water and energy cycle processes.
