Subglacial Drainage Evolution Modulates Seasonal Ice Flow Variability of Three Tidewater Glaciers in Southwest Greenland - velocity and plume data
<p>This file contains four datasets:</p> <p>- ice velocity estimates of the area surrounding and including Kangiata Nunata Sermia, southwest Greenland, derived from Landsat imagery and from Sentinel 1 imagery</p> <p>- plume observations in this area</p> <p>- subglacial discharge at the terminus</p> <p>- glacier terminus positions</p> <p>A more complete description of these datasets will be provided in the publication with the same name (currently in review). The methods used to measure glacier terminus positions are described in https://doi.org/10.5194/esurf-6-551-2018 </p>
