Oceanographic Mooring: Temperature, Salinity, and Current Flow Data at Various Depths, Central-Western McMurdo Sound, 2023-Present

The 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 western McMurdo Sound.

The site will be revisited in during the 2024/25 field season to recover the instruments and download their data. Our intention is to collect a total of 36 months of data (3x 12-month deployment/recovery cycles) in order to characterise the Ice Shelf Water outflow and the scale of its inter-annual variability.
