Raw physical oceanography data beneath Filchner Ice Shelf (Southern Weddell Sea, Antarctica) from FISP/FISS moorings FSW1 and FSE2, July 2019 to January 2023


Sub-ice shelf ocean hydrography (temperature, salinity) data were recovered from moorings FSW1 and FSE2 on Filchner Ice Shelf during the FISP-Air airplane campaign in December 2022 - January 2023. Due to different technical failures, both moorings did not transmit their oceanographic data via iridium for several months/years. The sites were visited by plane and missing data were downloaded from a total of 11 SBE37IMP MicroCATs via the inductive modem tether. The downloaded data include the periods 01/2022 – 01/2023 (FSW1), 07/2019 – 10/2019 (FSE2), and 08/2020 – 01/2023 (also FSE2). The moorings were also successfully repaired in the field, and have since resumed sending their data via iridium again. The attached .zip file contains the original logfiles as recorded in the field (.cap files), selected auxiliary information, as well as a cleaned version of these data files. This sub-dataset will be merged with the existing time series since 2016 to yield a fully processed and quality-controlled dataset, which will be published separately. It was also planned to visit moorings FNE1 and FNE2, but these sites could not be reached due to challenging weather conditions. More campaign details are available in the attached field report. This data is part of the joint FISP (AWI) and FISS (BAS) projects.

We thank Antarctic Logistics & Expeditions (ALE) and their friendly staff in Salt Lake City, Punta Arenas, and Union Glacier for their logistical support during the campaign. We are most grateful to the camp manager Tim Hewette, field meteorologist Marc DeKeyser, travel safety manager Simon Abrahams, guide company liaison Samuel Wild and, in particular, to our field guide Tom Weston, who kept us safe and comfortable (and who shoveled tons of snow). We are further thankful to our four Kenn Borek Twin Otter pilots, Mike, Natalie, Rodney, and Mark, for the safe travels. We acknowledge funding from the AWI logistics for making this expedition possible.
