Description
Summary:Brief data description In 2019, winter and spring scientific research expeditions aboard the SA Agulhas II were conducted along the Good-Hope line (0 o E) to the Antarctic marginal ice zone (MIZ) in the north-eastern Weddell Sea region as part of the Southern oCean seAsonal Experiment (SCALE; Ryan-Keogh and Vichi, 2022). During the winter expedition, three polar Iridium Surface Velocity Profilers (p-iSVPs; MetOcean model) were deployed by the South African Weather Service (SAWS) between 27 July and 28 July 2019. These buoys were analysed in de Vos et al. (2022). The region of deployment consisted of pancake-ice conditions with an average ice thickness of 40-60 cm. The instruments were deployed by hand by three people, lowered by crane from the ship to the ice on a basket cradle. The first buoy (p-iSVP 1) was deployed in water, in between pancake ice floes, while the other two buoys (p-iSVP 2 and p-iSVP 3) were deployed on roughly circular ice floes > 3 m in diameter. These buoys were expendable devices ... : This research has been supported by the National Research Foundation of South Africa (grant no. 118745).
