Summary: | Temperature, salinity, and isotopic values data from sea ice samples taken during MOSAiC leg 4 (PS122/4). Sea ice samples were taken from Jaridge, Alli's Ridge, and the Remote Sensing site. The ice cores were extracted either with a 9-cm (Mark II) or 7.25-cm (Mark III) internal diameter ice corers (Kovacs Enterprise, US). During each coring event, ice temperature was measured in situ from a separate temperature core, using Testo 720 thermometers in drill holes with a length of half-core-diameter at 5–20 cm vertical resolution. Salinity ice cores were stored in sterile U-Lines bags and transported back to the ship within 2 hours of sampling. Ice bulk practical salinity was measured from melted core sections at 5 cm resolution using a YSI 30 conductivity meter (practical salinity scale, unitless). The relative volume of brine was estimated from ice salinity and temperature using Cox and Weeks (1983) for cold ice and Leppäranta and Manninen (1988) for ice warmer than –2°C. The data contains the event label (1), ... |
