Ocean Microstructure measurements using a Slocum glider in the Southern Ocean Marginal Ice Zone
<p>Ocean microstructure data were collected using a turbulence package mounted on a Slocum and deployed from RV SA Agulhas II in the North Eastern Weddell Sea, [60S; 0E], from December 2019 to February 2020. Observations conducted by the Southern Ocean Carbon-Climate Observatory, Smart Places, CSIR, for the project "Contemporary and Future Drivers of CO2 and Heat in the Southern Ocean" funded by NRF-SANAP (SNA170522231782, SANAP200324510487) and in collaboration with Polar Gliders, University of Gothenburg (Project: "Robotic Observations and Modelling of the Marginal Ice Zone" funded by the Wallenberg Academy Fellowship (WAF 2015.0186). Turbulence data were collected using a Rockland Scientific MicroRider mounted on the SLOCUM. Microshear was measured using two airfoil shear probes oriented orthogonally to each other. The measurements are from a 47 days of dive and climb profiles, with a maximum depth of 500 m. The dataset is processed and prepared following the SCOR Working Group ATOMIX guidelines and recommendations. The provided file includes daily arithmetic means of the dissipation rate of turbulent kinetic energy derived from the microrider measurements. Temperature, salinity, latitude and longitude were taken from the Slocum glider.</p>

Data used in "The daily-resolved Southern Ocean mixed layer: regional contrasts assessed using glider observations"
<p>These are the data used in the analysis and creation of figures in du Plessis et al. 2022: <em>The daily-resolved Southern Ocean mixed layer: regional contrasts assessed using glider observations</em> in support of open-code, transparency, and repeatability.</p> <p>Abstract:</p> <p>Water mass transformation in the Southern Ocean is vital for driving the large-scale overturning circulation, which transports heat from the surface to the ocean interior. Using profiling gliders, this study investigates the role of summertime buoyancy forcing and wind-driven processes on the intraseasonal (1-10 days) mixed layer thermohaline variability in three Southern Ocean regions southwest of Africa important for water mass transformation - the Subantarctic Zone (SAZ), Polar Frontal Zone (PFZ) and Marginal Ice Zone (MIZ). At intraseasonal time scales, heat flux was shown as the main driver of buoyancy gain in all regions. In the SAZ and MIZ, shallow mixed layers and strong stratification enhanced mixed layer buoyancy gain by trapping incoming heat, while buoyancy loss resulted primarily from the entrainment of cold, salty water from below. In the PFZ, rapid mixing linked to Southern Ocean storms set persistently deep mixed layers and suppressed mixed layer intraseasonal (1-10 days) thermohaline variability. In the polar regions, lateral stirring of meltwater from seasonal sea-ice melt dominated daily mixed layer salinity variability. We propose that these meltwater fronts are advected to the PFZ during late summer, indicating the potential for seasonal sea-ice freshwater to impact a region where the upwelling limb of overturning circulation reaches the surface. This study reveals a regional dependence of how the mixed layer thermohaline properties respond to small spatio-temporal processes, emphasizing the importance of surface forcing occurring between 1-10 days on the mixed layer water mass transformation in the Southern Ocean.</p> <p><strong>Related code:</strong> The accompanying code can be found at: <a href="http://doi.org/10.5281/zenodo.5076119">http://doi.org/10.5281/zenodo.5076119. </a>Navigate to github.com/marcelduplessis/duplessis-2021-SO-thermohaline for the latest version</p>

Ocean Biogeochemistry from Gliders as part of the Gulf of Maine North Atlantic Time Series
This dataset contains ocean biogeochemistry data from two Slocum gliders along the Gulf of Maine North Atlantic Time Series (GNATS) transect. The transect runs approximately east-west, with only a very minor change in latitude. The gliders are deployed on the western end of the transect, travel along the transect line to the eastern end, turn around and travel back along the transect to the western end, before being recovered. Each file contains data from one deployment (a glider “mission”), and thus contains both an eastbound and a westbound measurement of each variable. A full mission takes approximately 20 – 30 days. The data are gridded by longitude (0.01° intervals) and depth (1 m intervals). For more details on dataset preparation, see the Original Publication Citation and Data Processing Workflow below.
