Freshwater lakes of Ulu Peninsula, James Ross Island, north-east Antarctic Peninsula:origin, geomorphology and physical and chemical limnology
This study describes the origin, bedrock geology, geomorphology, hydrological stability and physical and chemical characteristics of a representative set of 29 lakes in the ice-free parts of the Ulu Peninsula, James Ross Island, located close to the northern tip of the Antarctic Peninsula. Based on...
