On the expression and distribution of glacial trimlines: a case study of Little Ice Age trimlines on Svalbard
Glacial trimlines are important features for constraining 3-dimensional palaeoglaciological reconstructions, but relatively little is known about the processes of their formation and preservation. A new classification scheme for the expression of glacial trimlines was presented by Rootes and Clark (...
