A modified Pacific Gyre SVP Drifter with a 400 m long tether and a bottom weight was deployed during Polarstern expedition PS118 (9 February - 10 April 2019) on the western Weddell Sea shelf. The drifter was deployed from ~2m-thick sea ice through an ice hole following a CTD profile. The inductive tether was equipped with two SBE37IM (CTD) and one SBE39IMplus (T). The surface buoy included a sensor to measure sea level pressure and temperature right above the sea ice. The surface unit sampled the sensors each 15-30 minutes, and subsequently transmitted the data via iridium to the Pacific Gyre data server. The drifter was deployed on 8 March 2019 and terminated the communication on May 2019.
