The funding of the PEF in its early years,associated issues and responses

ABSTRACT

The PEF was founded as a charity, relying almost entirely on public generosity for its funding. Its insecure financial basis was at odds with its ambitious programme of surveys and excavations, which required sizeable and stable funding for periods of years. This dichotomy precipitated financial crises which occasionally brought the organisation almost to its knees. Yet, despite all the odds, it managed to chalk up impressive achievements. The financial shortcomings and the ways in which they were addressed, as well as the special factors responsible for the ultimate success of early PEF endeavours, are examined and discussed.     

A dental study comparing age estimations of the human remains from the Swedish warship Vasa

The great Swedish warship Vasa capsized and sank in Stockholm harbour on her maiden voyage in 1628. The ship was raised from the seabed in 1961 and skeletal remains were recovered from at least 25 individuals, with teeth and jaws from 17 of them. The skeletal material was odontologically examined, including dental radiographs. Teeth lost both ante‐mortem and post‐mortem were recorded and variations in tooth anatomy noted. Acquired changes were recorded including enamel hypoplasia, attrition, dental caries and periodontal recession. Age estimations based on a separate odontological study, osteological changes and tooth attrition had been made in 1989. Ages were estimated additionally by three non‐destructive dental methods based on (a) the length of the apical translucent zone, (b) selected measurements both on intact teeth and from ratios on dental radiographs and (c) ratios of the length and width measurements on dental radiographs from selected teeth. Several sources of post‐mortem changes had been observed, among them vivianite in 33 teeth from four individuals. The results of the dental examination showed that few teeth had been lost ante‐mortem, there was a low caries rate and little loss of periodontal attachments. With few exceptions, there is fairly good agreement between the different methods of estimating age. Age estimates based on dental attrition were, however, significantly different from the other dental methods and age estimates calculated from apical translucency ought to be regarded with scepticism due to post‐mortem changes. The chronological ages of the victims will never be known, but age estimates based on all the age‐markers available will probably reach a fairly close approximation.

Coastal and marine studies in the department of geography and environment at the University of Aberdeen

ABSTRACT

The Department of Geography and Environment at the University of Aberdeen has a long history of coastal and marine teaching and research from the 1960s to the present day. Beginning with the work of Walton and latterly Ritchie, the paper traces the coastal and marine studies in the Geography degree programme, the development of the Marine and Coastal Resource Management degree, and the introduction of more recent courses such as Managing Our Coasts and Seas, Hydrography, and Land and Marine Conservation. Establishment of the Centre for Marine and Coastal Zone Management (CMCZM), and later the Aberdeen Institute for Coastal Science and Management (AICSM), provided a clear focus for continuing academic research into integrated coastal management and marine spatial planning. This complemented long-term involvement with Shell, SOTEAG (Shetland Oil Terminal Environmental Advisory Group), the Association for Geographic Information (AGI), OceanLab, the EUCC, and several Scottish coastal fora. The creation of the Unmanned Airborne Vehicle (UAV)/Unmanned Airborne System (UAS) Centre for Environmental Monitoring and Mapping (UCEMM) in 2014 brought together the role of remote sensing, GIS and photogrammetry in monitoring, mapping and modelling the coastal environment.     

Evaluation of bone strontium as a measure of seafood consumption

The recognition that bone strontium/calcium ratios reflect dietary levels of strontium and that seawater has a high strontium content led some archaeologists to infer that seafood consumption produces high Sr/Ca ratios in bone. Analyses of seawater and of marine organisms reveal, however, a marine trophic effect comparable to the trophic effect seen in terrestrial food chains. This marine trophic effect reduces the Sr/Ca levels in seafood such that marine dietary resources have Sr/Ca levels comparable to those of terrestrial resources. Thus, bone Sr/Ca ratios can not differentiate consumption of marine and terrestrial resources. Also, Sr/Ca of bones from archaeological sites where seafood was an important component of diet were found to be within the range of entirely terrestrial diets.
