​Over the past week, the Tzortziou Group and collaborators from NRL and NASA have been collecting measurements aboard the R/V Ukpik to monitor the changing riverine fluxes and water quality in Alaska’s North Slope coastline - a region of high vulnerability to changes in the Arctic, characterized by increasing coastal erosion, permafrost thaw, rapid melting of snow and ice, and changing hydrological flow patterns...
