We deployed to vertical profiling floats from the ship SA Agulhas II during the SANAE IV supply voyage 2018/2019 along the prime meridian close to Maud Rise. Both floats were manufactured by NKE, type Arvor I and are equipped with sensors for temperature, salinity and pressure and measure on a daily to 3-daily sampling rate. The first profiling float was deployed on 18 December 2018 at 66.2° S, 0.0° E and the second float was deployed on 18 February 2020 at 65°S, 0.0° E. Both datasets continue until May 2021. The first profiling float deployed drifted over and along the steep topography of Maud Rise, providing possibilities to research the water properties and dynamics around Maud Rise in more detail. The other profiling float drifted southwestwards. More detailed information, including plots of the trajectories and profiles of our plots can be found in a paper that we submit in connection to this dataset: Observed mixing at the flanks of Maud Rise in the Weddell Sea, submitted to Geophysical Research Letters, by Martin Mohrmann, Sebastiaan Swart and Céline Heuzé.
