| Although the use of deep-sea imagery considerably increased during the last decades, reports on nekton falls to the deep seafloor are very scarce. Whereas there are a few reports describing the finding of whale carcasses in the deep north-eastern and south-eastern Pacific, descriptions of invertebrate or vertebrate food-falls at centimetre to metre scale are extremely rare. After 4 years of extensive work at a deep-sea long-term station in northern polar regions (AWI-"Hausgarten"), including large-scale visual observations with various camera systems covering some 10 000 m(2) of seafloor at water depths between 1250 and 5600 m, this paper describes the first observation of a fish carcass at about 1280 m water depth, west off Svalbard. The fish skeleton had... |

| Temporal variations in activity and biomass of the smaller benthic biota (size range: bacteria up to small meiofaunal organisms) were investigated on the Goban Spur continental margin (NE Atlantic) within the framework of the multidisciplinary research programme OMEX (''Ocean Margin Exchange'') sponsored by the European Union. Activities and biomasses were estimated analysing a series of biogenic sediment compounds (enzymes, adenylates, DNA, phospho-lipids, particulate proteins). In contrast to the very time-consuming sorting, enumeration and weighing of organisms, the determination of biochemical sediment parameters represents a useful method to obtain rapid information on ecological dynamics within benthic systems. Measurements of activity and biomass... |
