IMIS

The project was a three-year multidisciplinary study of the abyssal benthic boundary layer in the northeast Atlantic. The aim of BENGAL was to determine how the seabed community and the geochemistry of the sediments change seasonally in response to a highly seasonal input of organic matter from the overlying water column. It did this by organising an intensive sampling programme on 14 research cruises over a two-year period and using a range of observational techniques including time-series sediment traps, marine snow cameras, benthic lander systems, long-term moorings and time-lapse photography. The study area was located in the middle of the Porcupine Abyssal Plain at a water depth of about 4850 m, 270 km southwest of Ireland (central location: 48°50′N 16°30′W). The BENGAL project involved 17 partners from 9 European countries
