St Helena Bay Monitoring Line (SHBML) on the Ellen Kuzwayo Voyage 085, March 2011

This St Helena Bay Monitoring Line (SHBML) cruise was conducted on the Ellen Kuzwayo Voyage 085 in March 2011. This is a long-term monitoring line conducted off the coast of Elands/St Helena Bay on the west coast of South Africa. SHBML started in 2000 as a BENEFIT-driven project on "shipboard monitoring" which linked with similar lines run in Namibia and Angola. The aims were to obtain seasonal and interannual information on the hydrology and productivity of the area. It was incorporated under the Integrated Ecosystem Programme: Southern Benguela (IEP:SB) in 2013 consolidating a long-term, multi-decadal time-series (from 1951 onward) of information for this important region and has continued monitoring in the form of the IEP:SB. The programme is a multi-disciplinary, collaborative and capacity building platform undertaking relevant science, including updating technology, with the aim to develop ecosystem indicators that can be used to effectively monitor and understand the Southern...

Raw SDS data from Gough Island Relief on SA Agulhas II Voyage 017, September 2015

This is raw Scientific Data System (SDS) data from the SA Agulhas II voyage 017, Gough Island Relief 03 September 2015 to 06 October 2015. The Gough Island Relief Voyage is an annual cruise undertaken by the Department of Environmental Affairs (DEA) to change the overwintering team in Gough Island and to replenish the supplies at the British’s leased Gough Island Research base. The cruise also serves as a means to transport the residents and/or visitors to Tristan da Cunha using a signed agreement between South Africa and United Kingdom (UK). This voyage was to deliver the Gough 61 team to the island and return with the Gough 60 team. The scope of ship-based science for this takeover voyage was limited to underway observations and SAWS drifting buoy deployments.

Long-term monitoring of inshore temperatures in Elands Bay to support physiological research

To better understand the physiological effects of climate change and ocean acidification on marine organisms, information on the environmental conditions experienced in their natural habitats is required. Data from long-term monitoring studies capture in situ variability of environmental parameters that are used to relate experimental findings with field conditions. Elands Bay on the west coast of South Africa is a key location for such research and monitoring. It is a popular location for West Coast rock lobster (Jasus lalandii) fishing and therefore an important sentinel site for a commercial fishery species and the benthic communities upon which it depends. Low pH conditions exist along the west coast due to effects of upwelling, while cold-bottom waters in Elands Bay often result in low oxygen events responsible for mass walkouts of rock lobster. Additional exposure to extreme stressors associated with climate change can exacerbate impacts on their physiological processes. For...

Processed Expendable Bathythermograph (XBT) casts collected during the 2013 Marion Relief Voyage on SA Agulhas Voyage 007

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. Here we present 33 processed XBT casts collected along the Crossroads Transect, between 10 May 2013 and 15 May 2013, during the 2013 Marion Relief Voyage.

Short-term observations of daily bottom temperatures on the continental shelf off Port St Johns, along the east coast of South Africa (July 2013 - December 2013)

Between 2013 and 2014, a short-term mooring deployment was conducted to determine the oceanographic characteristics and variability off Port St Johns, along the east coast of South Africa. One mooring (PJ) was deployed, at a depth of 95m, between July 2013 and September 2014. This mooring measured currents, as well as sub-surface bottom temperatures on the continental shelf off Port St Johns on the east coast of South Africa. Here we present processed daily bottom temperatures (90 m) from an Acoustic Doppler Current Profiler (ADCP) at location PJ (31.73°S; 29.51°E) on the continental shelf off Port St Johns, between July 2013 and December 2013.

Processed underway Thermosalinograph (TSG) observations from the Benguela Air-Sea CO2 and Heat Flux Experiment on the Algoa Voyage 278, December 2021

Here we present the 6-second resolution processed Thermosalinograph (TSG) data collected between 06 December and 19 December 2021 during the Benguela Air-Sea CO2 and Heat Flux Experiment cruise on the Algoa Voyage 278. 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). The cruise operated on the West Coast of South Africa at a fixed location between Station 4 and 5 of the St. Helena Bay monitoring line (SHBML) with the ship's bow into the...
