Description
From 2015-01-09 to 2015-01-19, this dataset contains profiles of water conductivity, temperature, pressure, and derived salinity in the Ross Ice Shelf cavity near the Whillans Ice Stream grounding zone. It also includes mean and standard deviation of current speed at mid-depth. The data are provided by NOAA NCEI.
Use Cases
Modeling sub-ice shelf ocean circulation based on water temperature and conductivity profiles.
Analyzing the physical properties of the water column in an ice shelf cavity based on pressure and derived salinity data.
Studying current dynamics near the ice-shelf base based on mean and standard deviation of current speed.
Investigating the grounding zone environment of the Whillans Ice Stream based on the described location and measurements.
Strengths
Provides specific physical measurements: water thickness in the cavity is 10.35 m.
Includes derived practical salinity and current statistics, adding analytical value.
Reports precise location and ice shelf thickness: 755 m thick at the site.
