A new Antarctic foraminiferal species for detecting climate change in sub-Recent glacier-proximal sediments
Abstract Cribroelphidium webbi sp. nov. is the only adequately described sub-Recent elphidiid foraminifer from Antarctica. In Admiralty Bay (King George Island, South Shetland Islands), it is found at several locations within inner fiord setting at water depths between 33 and 165 m, but most commonl...
