Drill hole measurements of fast ice and sub-ice platelet layer thickness,...
Antarctica New ZealandThe thicknesses of sea ice and sub-ice platelet layer were measured at regular intervals on fast ice in McMurdo Sound, Antarctica in November and December of 2011. Thirty-metre cross-profiles were established at each site, and snow depths were measured at 0.5 m intervals along the transect lines with a metal ruler. A mean snow depth for each site was...Created 25 March 2025 • Updated 25 March 2025 -

Drill hole measurements of fast ice and sub-ice platelet layer thickness,...
Antarctica New ZealandHere, we present drill hole measurements carried out at 14 field sites distributed over a ~1500 km^2 area of fast ice in the south of McMurdo Sound, Antarctica between 1 and 19 November 2018. At each site, five holes were drilled in the fast ice at the centre and end points of two cross‐profile lines, each 30 metre long. Sea ice and SIPL thicknesses were...Created 25 March 2025 • Updated 25 March 2025 -

Antarctica New ZealandThe oceanographic mooring (-77.81830000, 165.40590000) which records temperature, salinity, and current flow at multiple depths for full 12-month cycles represents a step-change in our ability to monitor the flow of Ice Shelf Water – which carries the signature of deep ice shelf melt – northwards and out of the Ross/McMurdo Ice Shelf cavity through...Created 25 March 2025 • Updated 25 March 2025 -
Temperature, salinity and acoustic backscatter observations and tidal model...
Antarctica New ZealandTemperature and salinity observations were made at nominal depths of 75 m and 100 m, respectively, by Sea Bird Electronics sensors. Acoustic volume backscatter measurements were made by an ASL Environmental Sciences Acoustic Zooplankton Fish Profiler (AZFP) operating at four-frequencies (125 kHz, 200 kHz, 455 kHz and 769 kHz). The AZFP profiled the top 25...Created 25 March 2025 • Updated 25 March 2025 -
