Extract

An attempt was made to interpret the core to core variation in oxygen uptake observed during an in situ determination of sediment community oxygen consumption (SCOC) at a station in the Rockall Trough using the “suspended core” technique. No direct relationships between macrofaunal abundance or biomass and SCOC were observed. The results obtained suggested that the use of experimental chambers of small cross-sectional area (26.2cm2) allow for greater influence on SCOC of the activity of individual organisms which would otherwise be averaged out by larger, grab-type enclosures. The possible significance of other components of the benthos is discussed.
