Svalbard REU: Tidewater glacier response to changes in fjord oceanography, Kongsfjorden, Svalbard
Evaluating glacial meltwater processes in areas that are sensitive to changes in climate, such as the High Arctic, establishes direct links between atmospheric and oceanographic trends and tidewater glacier responses.

Evaluating glacial meltwater processes in areas that are sensitive to changes in climate, such as the High Arctic, establishes direct links between atmospheric and oceanographic trends and tidewater glacier responses.
