Greater Gulf of Alaska ice-marginal lake perimeters over 1984-2018
A sub-sample of ice-marginal lake (a lake in direct contact with a glacier) perimeters across the greater Gulf of Alaska region as they evolved over 1984-2018. These data were used to characterize regional lake area change and assess potential physical controls (e.g., topographic, climatic, and glac...
