Tephra and ecological studies of Limnopolar Lake, Byers Peninsula, Livingston Island. ...
Limnopolar Lake, Livingston Island, situated close to the tip of the northern Antarctic Peninsula (62°40'S, 61°00'W), has experienced a long history of primary and secondary tephra inputs from nearby volcanic centres. Background levels of tephra in a sediment core collected from th...
