Raw multibeam bathymetry data collected around the sub-Antarctic Prince Edward Islands on board the R/V Akademik Tryoshnikov during the austral summer of 2016/2017 as part of the Antarctic Circumnavigation Expedition (ACE).
<p><strong>Dataset abstract</strong></p> <p>An ELAC Nautik 3020 multibeam echo sounder with a 20 kHz transducer mounted on the hull of the R/V Akademik Tryoshnikov, was used to collect multibeam bathymetry data during the Antarctic Circumnavigation Expedition (ACE). This particular dataset was collected around the sub-Antarctic Prince Edward Islands in the austral summer of 2016/2017.</p> <p>Bathymetry data were used live during the cruise to look for suitable locations where benthic trawling and remotely-operated vehicle deployments could take place, rather than to undertake specific bathymetric surveys.</p> <p>This raw dataset is provided without calibration information for the surface sound velocity or instrumentation itself and should be used with due caution.</p> <p><strong>Dataset contents</strong></p> <ul> <li>lineYYYYDDmonHHMMSS.xse, data file, proprietary format</li> <li>*.txt, ancillary file, ASCII</li> <li>location.hydrostar, ancillary file, ASCII</li> <li>data_file_header.txt, metadata, text</li> <li>README.txt, metadata, text</li> </ul> <p><strong>Dataset license</strong></p> <p>This raw multibeam bathymetry dataset is made available under the Creative Commons Attribution 4.0 International License (CC BY 4.0) whose full text can be found at https://creativecommons.org/licenses/by/4.0/</p>

Data used in "The Complex Role of Storms in Modulating Air-Sea CO2 Fluxes in the sub-Antarctic Southern Ocean"
<p>The data included in this repository were used to generate the figures for the paper "The Complex Role of Storms in Modulating Air-Sea CO2 Fluxes in the sub-Antarctic Southern Ocean" in Geophysical Research Letter.</p> <p>Abstract:</p> <p>"The intra-seasonal CO<sub>2</sub> flux (FCO<sub>2</sub>) variability across the Southern Ocean is poorly understood due to sparse observations at the required temporal and spatial scales. Twinned Waveglider-Seaglider experiments were used to investigate how storms influence FCO<sub>2</sub> through both the gas transfer velocity (k<sub>w</sub>) and the air-sea gradient in partial pressure of CO<sub>2</sub> (ΔpCO<sub>2</sub>) in the sub-Antarctic zone. Winter-spring storms caused ΔpCO<sub>2</sub> to weaken (by 15-55 μatm) due to mixing/entrainment and weaker stratification. This response in ΔpCO<sub>2</sub> was in phase with k<sub>w</sub> resulting in a counteractive weakening in FCO<sub>2</sub> (by 6.6 - 26.5% per storm), despite the wind-driven increase in k<sub>w</sub>. Stronger stratification during summer explained the weaker sensitivity of ΔpCO<sub>2</sub> to storms, instead its thermal drivers dominated the ΔpCO<sub>2 </sub>variability. These results highlight the importance of observing synoptic-scale variability in ΔpCO<sub>2</sub>, the absence of which may propagate significant biases to the mean annual FCO<sub>2</sub> estimates from large-scale observing programmes and reconstructions."</p> <p>The data collected from the Wave Glider, such as the concentration of CO<sub>2</sub> in the atmosphere (xCO<sub>2air</sub>) and in the ocean (xCO<sub>2sea</sub>), surface temperature and salinity were used to calculate the different parameters of the bulk CO<sub>2</sub> flux formula (FCO<sub>2</sub> = k<sub>w</sub> x ko x ΔpCO<sub>2</sub>). Note that the meteorological weather station of one of the Wave Gliders was faulty and the wind speed, wind direction and wind stress data was replaced by hourly ERA5 data provided by ECMWF available at <a href="https://doi.org/10.24381/cds.bd0915c6">https://doi.org/10.24381/cds.bd0915c6</a>. </p> <p>The temperature, pressure and salinity data collected by the Seaglider were used to calculate the Mixed Layer Depth and the Brunt Vaisala Frequency of the first 300m of the ocean.</p>
