    Description: This dataset contains the hydrographic bottle data collected with the ship based CTD rosette during the cruise PS124 - COSMUS (Continental Shelf Multidisciplinary Flux Study). The CTD is an SBE911plus with 24 bottles, 12 liters each. The CTD/Rosette was equipped with duplicate sensors for temperature, salinity, and oxygen, and one sensor each for pressure, substance fluorescence Chl. a, and beam transmission. An altimeter was mounted to monitor the distance to the seafloor. The CTD profile data, the cruise report as well as publications using this data are linked below.

    Description: This dataset contains the hydrographic profile data collected with the ship based CTD rosette during the cruise PS124 - COSMUS (Continental Shelf Multidisciplinary Flux Study). The CTD is an SBE911plus with 24 bottles, 12 liters each. The CTD/Rosette was equipped with duplicate sensors for temperature, salinity, and oxygen, and one sensor each for pressure, substance fluorescence Chl. a, and beam transmission. An altimeter was mounted to monitor the distance to the seafloor. The dataset contains calibrated and quality-controlled parameters as well as uncalibrated parameters, where no quality control was applied. Quality flags are given based on paragraph 6. "Quality flags" from https://www.seadatanet.org/content/download/596/file/SeaDataNet_QC_procedures_V2_%28May_2010%29.pdf . The CTD bottle data, the cruise report as well as publications using this data are linked below. Additional information on the sensor used for the final data set as well as the water depth is given in a separate info-file.

    Description: 〈jats:p〉Abstract. The transport of water masses with ocean circulation is a key component of the global climate system. In this context, the Filchner Trough in the southern Weddell Sea is critical, as it is a hotspot for the cross-shelf-break exchange of Dense Shelf Water and Warm Deep Water. We present results from Lagrangian particle tracking experiments in a global-ocean–sea-ice model (FESOM-1.4) which includes ice-shelf cavities and has eddy-permitting resolution on the southern Weddell Sea continental shelf. With backward and forward experiments, we assess changes between a present-day and a future (SSP5-8.5) time slice in the origin of waters reaching the Filchner Ice Shelf front and the fate of waters leaving it. We show that particles reaching the ice-shelf front from the open ocean originate from 173 % greater depths by 2100 (median; 776 m as compared to 284 m for the present day), while waters leaving the cavity towards the open ocean end up at 35 % shallower depths (550 m as compared to 850 m for the present day). Pathways of water leaving the continental shelf increasingly occur in the upper ocean, while the on-shelf flow of waters that might reach the ice-shelf cavity, i.e., at deeper layers, becomes more important by 2100. Simultaneously, median transit times between the Filchner Ice Shelf front and the continental shelf break decrease (increase) by 6 (9.5) months in the backward (forward) experiments. In conclusion, our study demonstrates the sensitivity of regional circulation patterns in the southern Weddell Sea to ongoing climate change, with direct implications for ice-shelf basal melt rates and local ecosystems. 〈/jats:p〉
