  • Piston core PS1506, a repeat of core PS1387, was collected from a midslope bench on the continental margin on the southern limb of the Weddell Gyre in the vicinity of cores PS1388 and PS1389. At these core sites in the Weddell Sea, polynyas enabled continuous primary productivity and benthic life during glacial periods. PS1506 is situated at 2426 m water depth. The core is beneath the depth of the average modern saturation horizon based on the carbonate chemistry of eastern Weddell Sea waters but above the local CCD (carbonate compensation depth).

  • Temperature data were collected from a tidepool at Rothera Point, Antarctica every two minutes from February 1999 to May 2000, with the aim of documenting tidal, diurnal and seasonal variability.

  • This data set provides processed Ku- and Ka-band fully-polarimetric backscatter and derived polarimetric parameters from hourly scans, acquired using the KuKa radar, during Legs 1, 2, 4 and 5 of the 2019-2020 MOSAiC International Arctic Drift Expedition. Scans were acquired during winter (Legs 1 and 2), advanced melt (leg 4) and freeze-up (Leg 5) seasons, from various Remote Sensing (RS) sites, located in the MOSAiC ice floe. The first deployment of the KuKa radar was on 18 October 2019 at RS1 site and the radar was retreated (due to ice break up) on 18th November. The radar was redeployed on 29th November at RS2 site until 13th December when cracks were observed at the site and the instrument was turned off and moved to a safe location. The radar was redeployed at RS3 site and started measuring again on 21st December 2019 until 31st January 2020, after which the radar was taken off the RS site to conduct maintenance. The radar was not operational during Leg 3. During Leg 4, the radar was operational between 25th June and 19th July 2020, and later retreated back to the ship, for deployment in Leg 5. The radar was deployed on 24th August 2020 and operational until the end of the MOSAiC expedition. The dataset was collected by MOSAiC Team ICE participants and processed by Vishnu Nandan at the University of Manitoba, Canada. This work was funded in part through NERC grant NE/S002510/1, the Canada 150 Chair Program and the European Space Agency PO 5001027396. The authors thank Marine Environmental Observation, Prediction and Response Network (MEOPAR) Postdoctoral Fellowship grant to Vishnu Nandan. The authors also thank the crew of R/V Polarstern and all scientific members of the MOSAiC expedition for their support in field logistics and field data collection.

  • This dataset comprises hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, during June 1981. It incorporates a CTD survey in the Irish Sea. The data were collected by the University of Wales, Bangor School of Ocean Sciences as part of a survey cruise contributing to research directed toward understanding how the physics of the Irish Sea and surrounding regions (Celtic Sea, St, George's Channel, North Channel and Clyde Sea) determine biogeochemical processes and sediment transport.

  • The dataset comprises 38 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from across the Rockall area during September 2005. A complete list of all data parameters are described by the SeaDataNet Parameter Discovery Vocabulary (PDV) keywords assigned in this metadata record. The data were collected by the Fisheries Research Services Aberdeen Marine Laboratory.

  • The dataset comprises 54 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from across the North Sea area specifically the Orkney area, during May of 1998. A complete list of all data parameters are described by the SeaDataNet Parameter Discovery Vocabulary (PDV) keywords assigned in this metadata record. The data were collected by the Fisheries Research Services Aberdeen Marine Laboratory.

  • The dataset comprises 6 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from across the North Sea area specifically the Firth of Forth, east coast of Scotland, Wee Bankie, Marr Bank and Farne Deeps to Scaup bank. Data were collected during March and April 2000. A complete list of all data parameters are described by the SeaDataNet Parameter Discovery Vocabulary (PDV) keywords assigned in this metadata record. The data were collected by the Fisheries Research Services Aberdeen Marine Laboratory.

  • The dataset comprises 7 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from across the Inner Seas off the west coast of Scotland area specifically the Loch Kishorn, Loch Alsh, Loch Duich, Loch Hourn, Loch Nevis, Loch Sunart, Sound of Sleat. The data were collected during January of 2003. A complete list of all data parameters are described by the SeaDataNet Parameter Discovery Vocabulary (PDV) keywords assigned in this metadata record. The data were collected by the Fisheries Research Services Aberdeen Marine Laboratory.

  • The dataset comprises 10 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from the Inner Seas off the west coast of Scotland area specifically the Loch Torridon, during May of 2001. A complete list of all data parameters are described by the SeaDataNet Parameter Discovery Vocabulary (PDV) keywords assigned in this metadata record. The data were collected by the Fisheries Research Services Aberdeen Marine Laboratory.

  • The dataset comprises 107 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, within the North East Atlantic Ocean area. It incorporates a short section of the Ellett Line east of the Anton Dohrn Seamount, plus a comprehensive survey of the Scottish shelf from the North Channel to Cape Wrath. The data were collected during June and July of 1979. A complete list of all data parameters are described by the SeaDataNet Parameter Discovery Vocabulary (PDV) keywords assigned in this metadata record. The data were collected by the Scottish Marine Biological Association.
