Margie Turrin captured this shot of the small village of Kullorsuaq in northwest Greenland, where she and postdoc Dave Porter are working with local community members to collect water column temperature profiles. These ocean measurements will help scientists understand why nearby Alison is surging to the sea faster than other glaciers in the area. Learn more about this project from Turrin and Porter’s website and follow their blog for updates from the field.
