Water temperature, salinity, and others collected from autonomous underwater vehicle in Sarqardleq Fjord, West Greenland from 2012-07-18 to 2012-07-24
Measurements of near-ice ( less than 200 meters (m)) hydrography and near-terminus subglacial hydrology are lacking, due in large part to the difficulty in working at the margin of calving glaciers. Here we provide detailed hydrographic and bathymetric measurements collected with an autonomous under...

description |
Measurements of near-ice ( less than 200 meters (m)) hydrography and near-terminus subglacial hydrology are lacking, due in large part to the difficulty in working at the margin of calving glaciers. Here we provide detailed hydrographic and bathymetric measurements collected with an autonomous underwater vehicle as close as 150m from the ice–ocean interface of the Saqqarliup sermia–Sarqardleq Fjord system, West Greenland. Analysis in combination with modeled and observed subglacial discharge locations and magnitudes, showed evidence of two main types of subsurface glacially modified water (GMW) with distinct properties and locations (Stevens et al., 2016, doi:10.5194/tc-10-417-2016). The near-ice observations and subglacial discharge routing indicate that runoff from this glacier occurs primarily at two discrete locations and gives rise to two distinct glacially modified waters. Furthermore, the location with the largest subglacial discharge is associated with the lighter, fresher glacially modified water mass, qualitatively consistent with results from an idealized plume model. |
