Water column acoustic data collected in the Amundsen and Bellingshausen Seas (from 2008-02-26 to 2008-04-10) during cruise JR179. Multi-frequency (38,120 and 200 kHz) acoustic data were collected using a Simrad EK60 echo sounder. The dataset comprises of calibrated and processed 38 kHz volume backscattering strength (Sv, dB re 1m-1). Data processing was undertaken using Echoview and Matlab. Processed netCDF data files are made available as part of the NERC Southern Ocean Network of Acoustics (SONA) and the EU MESOPP project.

Datasets from a deep sediment trap (3700m) mooring deployed in the Southern Ocean, north-west of South Georgia in December 2014 during the marine cruise JR304 and recovered in November 2015 by the marine cruise JR15002.

Datasets from a shallow water mooring deployed in the Southern Ocean, north of South Georgia in April 2003 during the marine cruise JR87 and recovered in November 2003 by the marine cruise JR92.

Water column acoustic data collected in the Scotia Sea (from 2011-12-30 to 2012-01-16) during cruise JR260. Multi-frequency (38,120 and 200 kHz) acoustic data were collected using a Simrad EK60 echo sounder. The dataset comprises of calibrated and processed 38 kHz volume backscattering strength (Sv, dB re 1m-1). Data processing was undertaken using Echoview and Matlab.

The flow-line model was designed to enable estimation of the age and surface origin for various ice bodies identified within hot-water drilled boreholes on Larsen C Ice Shelf. Surface fluxes are accumulated, converted to thicknesses, and advected down flow from a fixed number of selected points. The model requires input datasets of surface mass balance, surface velocity, vertical strain rates, ice-shelf thickness, and a vertical density profile. This model is part of a larger project. Input datasets such as density profiles and trajectory vectors are available separately. Resolution is dependent on the input datasets. Funding was provided by the NERC grant NE/L005409/1.
