title: South African National Antarctic Expedition (SANAE) on the SA Agulhas II Voyage 061, December 2023

description: The South African National Antarctic Expedition (SANAE) is an annual voyage undertaken by the Department of Forestry, Fisheries and the Environment (DFFE) to change the overwintering teams in Antarctica and to replenish the supplies at the SANAE IV Research base. This voyage was to deliver the SANAE 63 over wintering team to the research base and return with the SANAE 62 team. The cruise was undertaken between 26 December 2023 and 20 February 2024 with full scientific complement. For this voyage, the cruise track was adjusted to accommodate stop-overs at the Prince Edward Islands (PEI) on both the south bound transect and north bound transect to and from Antarctica. The main ship-based research objectives was to undertake underway sampling along the transects, which include XBT sampling between PEI and Antarctica; Underway PCO2; nutrient and chlorophyll sampling and the deployment of ARGO floats.

title: Raw Expendable Bathythermograph (XBT) casts collected during the Marion Island Relief Voyage on the SA Agulhas II Voyage 057, May 2023

description: Raw Expendable Bathythermograph (XBT) casts collected in the South West Indian Ridge area and along the Crossroads Transect, between 14 May 2023 and 17 May 2023, during the 2023 Marion Relief Voyage on the SA Agulhas II Voyage 057.
description: Here we present 36 raw Expendable Bathythermograph (XBT) casts collected in the South West Indian Ridge area and along the Crossroads Transect, between 14 May 2023 and 17 May 2023, during the 2023 Marion Relief Voyage on the SA Agulhas II Voyage 057. 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 Conductivity-Temperature-Depth (CTD) stations and XBT casts, where the XBT casts are done, at set intervals, between CTD stations to complement the CTD data.
description: Sippican WinMK21 Data Acquisition and Post-Processing Software is used for data collection of T7 Deep Blue Expendable Bathythermograph (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 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 36 XBT casts.

title: Raw underway Thermosalinograph (TSG) observations from the International Indian Ocean Expedition 2 (IIOE2) cruise on SA Agulhas II Voyage 032, June 2018

description: Raw underway Thermosalinograph (TSG) observations from SA Agulhas II Voyage 032, June 2018 - July 2018
description: Here we present the 6-second resolution raw Thermosalinograph (TSG) data collected, between 10 June 2018 and 13 July 2018, during voyage 032 on the SA Agulhas II. 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).
description: The SeaBird SBE45 Thermosalinograph (TSG) is used on the SA Agulhas II for the collection of underway near-surface temperature and conductivity measurements. The underway seawater is obtained from a depth of 7m below the surface and pumped through the TSG. Data is collected using the most recent SeaBird (SBE) SeaSave software and processed using the most recent SBE Dataprocessing software. The software was set to record data at 6 second intervals for the duration of the cruise, between 10 June and 13 July 2018. Data was collected in the southern part of the Benguela Current Large Marine Ecosystem (BCLME) region and in the Agulhas Current Large Marine Ecosystem (ACLME) region.

Unreliable TSG measurements can result from a variety of problems encountered during the cruises, including insufficient water flow, extreme air bubbling during severly adverse weather conditions, debris trapped in the system, or a variety of electronic failures. Detailed visual inspection of the ship trajectory and TSG measurements, as well as comparisons with other concurrent and historical near-surface measurements, and expert knowledge of local conditions, were used to identify and remove all unreliable data.

title: Marion Island Relief Voyage on the SA Agulhas II Voyage 042, April 2020

description: The 2020 Marion Relief Voyage 042 on SA Agulhas II offered the 8th opportunity to conduct multi-disciplinary, ship-based oceanographic research on board the SA Agulhas II en route to, and around, the sub Antarctic Prince Edward Islands. Due to the world wide Covid-19 pandemic and the subsequent measures implemented by the South African government to contain the spread of the Covid-19 virus in South Africa, the main research objectives (land-based and ship-based) normally associated with the Marion Relief voyage (as submitted through SANAP3 applications) were cancelled. This cruise was comprised mainly of underway sampling.
