Morphologically similar benthic foraminifera taxa are difficult to separate, resulting in incorrect identifications, complications understanding species-specific ecological preferences, and flawed reconstructions of past environments. Here we provide descriptions and illustrated guidelines on how to separate some key Arctic–North Atlantic species to circumvent taxonomic confusion, improve understanding of ecological affinities, and work towards more accurate palaeoenvironmental reconstructions.

Integrated micropaleontological (planktic and benthic foraminifera, diatoms, and silicoflagellates) analysis, together with textural and geochemical results of a deep-sea core from the Hallett Ridge (northwestern Ross Sea), provides new data for late Quaternary (23–2 ka) paleoenvironmental and paleoceanographic reconstructions of this region. Results allow us to identify three time intervals: the glacial–deglacial transition, the deglacial period, and the interglacial period.
