Abstract

Bioturbation processes form the interface between seabed biology and geochemistry. The 'environmental forcing' referred to in the programme is likely to vary both with depth (eg. fjordic-shelf-slope-abyss) and latitude (north-south gradients in intensity and interannual variability of pulsed OM input). Bioturbation therefore provides a crossover between the two main themes of the Northern Seas programme. Work to be carried out from JCR should be seen as an essential supplement to the Wyville-Thomson work carried out on D257. To test the reality or otherwise of benthic biogeochemical 'provinces' we require comparable data from a range of sites in the water masses north and south of the WT Ridge (differences between our WTN and WTS stations does not in itself amount to a demonstration of 'provinces'). The WTS results can be put alongside existing data from previous studies in the Atlantic water mass (BENBO, SES), but at present we need more stations north of the ridge to compare with WTN.
