Benthic foraminiferal assemblages and environmental drivers along the Kveithola Trough (NW Barents Sea)
Accepted manuscript version, licensed CC BY-NC-ND 4.0. We describe the population density, biodiversity and vertical distribution in the sediment of benthic foraminifera, and their relationship to environmental parameters, in the Kveithola Trough (NW Barents Sea). Two staining methods, Cell Tracker...
