Dietary studies based on 24 h recalls were carried out on four oil installations in the Norwegian sector of the North Sea. Two hundred and three persons were interviewed about what they had eaten the previous 24 h. Food purchased for the installations in the previous 5 months was recorded. Results based on 24 h recalls showed that average daily intake of energy was 12.2 MJ of which 17% came from protein, 44% from fat and 39% from carbohydrate, including 8% from sugar. Meat, vegetables, fresh fruits, seafood (shellfish), french fries, eggs, cream and ice-cream were important components of the diet, while bread, fish and cereals played a minor role. Average daily intake (mg) of nutrients were: calcium 1244, iron 15, vitamin A 1049 μg, vitamin D 4.1 μg, thiamin 1.6, riboflavin 2.2, nicotinic acid 22, ascorbic acid 143. Dietary fibre intake, estimated as unavailable carbohydrate, was on average 19 g, and the average daily intake of cholesterol was 755 mg. Intakes were compared with the Norwegian recommended dietary allowance. Most of the employees chose a diet which when eaten over a longer period of time may contribute to the development of coronary heart diseases (CHD) and thereby increase the morbidity and mortality from CHD in the oil industry.

The purpose of writing this book was to explore aspects of human behaviour that have been, to varying extents, disregarded, overlooked, or ignored in terrestrial-dominated archaeology to date. Recognizing that the sea ‘is good to think’, it was envisaged that an exploration of North Sea archaeologies could launch something of a ‘maritime turn’. This final chapter considers the broad themes of the human past that have been enlightened through this study, and questions if and how these can be reproduced in land-based research. Five interrelated themes are presented here: the essence of nature–society interrelationships, the attribution of forms of agency to inanimate objects, deviant spaces, the essence of travelling long distances—including the skills and knowledge required for this—and finally, how the sea contributes to shaping social identities. The relationship that people had with their environment, or nature–society interrelationships, is fundamental to archaeological research on land and at sea. Explicitly or implicitly, terrestrial archaeology presents us with something of an irreversible progression towards ‘encultured’ landscapes—narratives wherein the land becomes increasingly less natural and more cultural (see chapter 2). In much of Europe, the ‘enculturation’ of the world started back in the Post-glacial. It continued throughout the Mesolithic, with the creation of paths through, and clearances within, otherwise natural landscapes. In the Neolithic, ‘enculturation’ took place through deforestation, and through the apportioning of symbolic significance to natural features and the construction of monuments relating to these. By the late Neolithic and early Bronze Age, large tracts of land were being accommodated to the needs of humans through the creation of field systems and settlements, producing ‘cultural landscapes’. From the middle Bronze Age onwards, according to accepted land-based archaeological thinking, it would appear that nature played at best a minor role, limited to the impact of climate and weather on the crops being cultivated. The study of the North Sea has fundamentally challenged the nature–culture dichotomy. The concept of ‘enculturation’ places Homo sapiens centre stage in a changing world, but underestimates the role played by the sea and rivers, as well as animals, trees, and plants, as important co-constructors of landscape.

The Phylum Planctomycetes

Planctomycetes are bacteria that were long thought to be unculturable, of low abundance, and therefore neglectable in the environment. This view changed in recent years, after it was shown that members of the phylum Planctomycetes can be abundant in many aquatic environments, e.g., in the epiphytic communities on macroalgae surfaces. Here, we analyzed three different macroalgae from the North Sea and show that Planctomycetes is the most abundant bacterial phylum on the alga Fucus sp., while it represents a minor fraction of the surface-associated bacterial community of Ulva sp. and Laminaria sp. Especially dominant within the phylum Planctomycetes were Blastopirellula sp., followed by Rhodopirellula sp., Rubripirellula sp., as well as other Pirellulaceae and Lacipirellulaceae, but also members of the OM190 lineage. Motivated by the observed abundance, we isolated four novel planctomycetal strains to expand the collection of species available as axenic cultures since access to different strains is a prerequisite to investigate the success of planctomycetes in marine environments. The isolated strains constitute four novel species belonging to one novel and three previously described genera in the order Pirellulales, class Planctomycetia, phylum Planctomycetes.

Abstract. Intact polar lipids (IPLs) are considered biomarkers for living biomass. Their degradation in marine sediments, however, is poorly understood and complicates interpretation of their occurrence in geological samples. To investigate the turnover of IPLs, a degradation experiment with anoxic sandy sediments from the North Sea was conducted. Intact cells of two organisms that do not naturally occur in North Sea sediments were chosen as IPL sources: (i) Saccharomyces cerevisiae, representative for ester-bound acyl lipids that also occur in Bacteria, and (ii) the archaeon Haloferax volcanii, representative for ether-bound isoprenoid lipids. Surprisingly, IPLs with phosphoester-bound head groups showed approximately the same degradation rate as IPLs with glycosidic head groups. Furthermore, the results indicate a relatively fast degradation of S. cerevisiae IPLs with ester-bound moieties (analogs of bacterial membrane lipids) and no significant degradation of archaeal IPLs with ether-bound moieties. Pore water and 16S rRNA-based DGGE analysis showed only a minor influence of the IPL source on microbial metabolism and community profiles. Due to our results, the IPL-based quantification of Archaea and Bacteria should be interpreted with caution.

Cyst Content

A minor shaly sequence in the middle of the Hartz Fjeld Formation, Milne Land, central East Greenland is dated as Hauterivian on the basis its dinoflagellate cyst content. The assemblage is compared with the dinotlagellate stratigraphy of the Spee ton Clay, England and the North Sea basin. This is the first report of Hauterivian sediments from East Greenland.
