The organic-walled genera Resigella and Conicotheca (Protista, Foraminifera) at two Arctic deep-sea sites (North Pole and Barents Sea), including the description of a new species of Resigella
We describe a new organic-walled foraminiferan species from the central Arctic Ocean (North Pole; 4,300 m water depth) and the Håkon Mosby Mud Volcano (HMMV) at the south-western Barents Sea continental margin (1,250 m depth) based on morphological features. Resigella polaris sp. nov. has a more or...
