Hydrologists And Glaciologists

This group collects the Earth Sciences subcategory's members whose defining work concerns hydrology and glaciology: rivers, groundwater, glaciers and ice sheets, and the physical processes that move water and ice across and beneath the Earth's surface over both short and geological timescales. It is the subcategory's smallest flat group, kept apart from Oceanographers, whose members study the open ocean specifically, and from Geophysicists And Seismologists, whose members study the Earth's solid interior rather than its surface water and ice.
