Abstract	Here we present 59 raw Expendable Bathythermograph (XBT) casts collected along the Crossroads Transect, between 13 May 2024 and 15 May 2024, during the 2024 Marion Relief Voyage on the SA Agulhas II Voyage 062. 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 compliment the CTD data.
Methods	Sippican WinMK21 Data Acquisition and Post-Processing Software is used for data collection of T7 Deep Blue XBT probes. The data is collected in .bin format and then converted to .txt files using software. The *.txt files contain some metadata at the top of the file, but not always fully completed by operators. There is no editing done to the data in the acquisition software and so the bottom readings, where the XBT loses signal, have not been removed for the 59 XBT casts.
