Hydrostatic pressure below Ross Ice Shelf from 2015-01-16 to 2015-03-16 (NCEI Accession 0209188)

A pressure sensor was suspended by a steel cable through a borehole in the Ross Ice Shelf into the ocean cavity. The sensor hung 761 m from the ice surface, roughly mid-depth in the 10-m-thick ocean cavity, within a water mass of almost constant potential density when it was sampled in January 2015. The site is located within a grounding zone, or flexure zone, wherein the ice shelf elevation does not respond hydrostatically to variations in ocean pressure.
