Data:  1997 Ano:  1997 Palavras-chave:  Dissolved oxygen Ecological distribution Food availability Geochemistry Nitrogen Oxic sediments Population density Sediment chemistry Nematoda [Nematodes] ANE Atlantic Goban Spur Resumo:  Nematode density along a depth gradient (206-2760 m) in the northeastern Atlantic (Goban Spur) is linearly and positively related to organic matter mineralization in the sediment. It is estimated that nematodes contribute at most 13% to total carbon turnover, and this contribution decreases with water depth. The vertical distribution of nematodes in the sediment closely follows concentration <i>vs</i> depth profiles of total nitrogen in the sediment. Both nematodes and total nitrogen tend to be more concentrated towards the surface with increasing water depth. There is no indication that nematode vertical distribution is directly influenced by the oxygen penetration in the sediment. However, it is hypothesized that the sediment oxygen concentration can explain the relatively greater importance of smaller organisms in benthic communities with increasing water depth. The nitrogen <i>vs</i> sediment depth profiles are consistent with a greater impact of larger organisms on sediments at the shallow stations and decreased sediment mixing with increasing water depth.
