The dataset was collected over 26 glider missions along the continental shelf of southeastern Australia, and is made up of over 33,600 CTD profiles from the surface to within 10 m of the bottom in water depths ranging 25–200 m, provides unprecedented high resolution observations of the continental shelf waters adjacent to a western boundary current, straddling the region where it separates from the coast.
The data descriptor paper, written by Amandine Schaeffer from the University of New South Wales along with a group of researchers from across the country, presents a high-resolution mean hydrography of the continental shelf along southeastern Australia, from repeat glider deployments over 8 years between 29.5°S and 33.5°S.
The data were quality controlled providing for the first time gridded mean fields for temperature, salinity and density, but also dissolved oxygen and chlorophyll-a fluorescence indicative of phytoplankton biomass.
The region is both physically and biologically significant, and is also in a hotspot of ocean warming. This data will be invaluable for understanding shelf stratification, circulation, biophysical and bio-geochemical interactions, as well as for the validation of high-resolution ocean models or serving as teaching material.
