Processed Expendable Bathythermograph (XBT) casts collected during the Marion Island Relief Voyage on the SA Agulhas II Voyage 045, May 2021

Here we present 57 processed Expendable Bathythermograph (XBT) casts collected in the South West Indian Ridge area and along the Crossroads Transect, between 08 May 2021 and 11 May 2021, during the 2021 Marion Relief Voyage on the SA Agulhas II Voyage 045. The South African component of the international South Atlantic Meridional Overturning Circulation project (SAMOC-SA) aims to characterise the time-mean and time-varying components of the SAMOC in the South Atlantic Ocean and monitor the variability of the main Southern Ocean frontal systems associated with the Antarctic Circumpolar Current (ACC), south of Africa. The Crossroads monitoring line, directly under the altimetry track N198, is sampled annually during the Marion Relief voyages, using a combination of CTD stations and XBT casts, where the XBT casts are done, at set intervals, between CTD stations to complement the CTD data. The 2021 Marion Relief Voyage 045 offered the 9th opportunity to conduct multi-disciplinary,...

Processed underway Thermosalinograph (TSG) observations from the SA Agulhas II Voyage 042, April 2020

A SeaBird SBE45 Thermosalinograph (TSG) is used to opportunistically collect underway near-surface temperature and conductivity measurements during research and monitoring cruises. Water is continuously pumped to the TSG from an intake located in the hull of the vessel, and the observations are continuously interfaced with navigational information. A temperature sensor close to the intake provides temperature measurements of the incoming water (T1). The temperature of the water inside the conductivity cell (T2) is used to accurately compute salinity (S) from the conductivity measurements (C). Here we present the 10-second resolution processed TSG data collected, between 21 April 2020 and 15 May 2020, during Voyage 042 on the SA Agulhas II.
