Underway Thermosalinograph Data: Punta Arenas–Puerto Williams– Antarctica (December-January 2023) ECA59

Underway Thermosalinograph Data: R/V Karpuj / INACH, December 2022–January 2023 Raw near-surface temperature and salinity data were acquired from 23 December 2022 to 13 January 2023 using an SBE-45 Sea-Bird thermosalinograph system installed on board the R/V Karpuj / INACH. The seawater intake was located at approximately 2 m depth. Data were recorded every 5 seconds. The raw data were subsequently processed using SBE Data Processing software.
