Integrated Ecosystem Programme: Southern Benguela (IEP:SB) on the Algoa Voyage 216, May 2015

The Integrated Ecosystem Programme: Southern Benguela was conducted on the Algoa Voyage 216, 06 to 15 May, 2015. The Integrated Ecosystem Programme is a multi-disciplinary, multi-institutional platform to undertake relevant science in the Southern Benguela; also functioning as a platform for collaboration and learning. All projects aim to develop an ecosystem indicator that can be used to effectively monitor and understand the Southern Benguela i.e physical, chemical, planktonic, microbial, seabird and benthic ecosystem indicators, used for ecosystem-based management. IEP:SB focuses on the biologically productive, cold waters of the Benguela Current Large Marine Ecosystem, which are inherently variable on short time-scales and responsive to changing weather patterms. The research aims to provide relevant, reliable and improved assessment of the ecosystem, in support of its effective management, preservation and conservation, so that South Africans can benefit from a healthy and...

Processed underway Thermosalinograph (TSG) observations from the Integrated Ecosystem Programme: Southern Benguela (IEP:SB) on the Algoa Voyage 282, May 2022

Here we present the 6-second resolution processed Thermosalinograph (TSG) data collected on the Integrated Ecosystem Programme: Southern Benguela (IEP:SB) cruise on the Algoa Voyage 282 between 10 May and 18 May 2022. 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 IEP:SB in 2013 consolidated 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...

Transkei Shelf Oceanography Cruise on the Algoa Voyage 241, July 2017

The Transkei Shelf Oceanography Cruise was conducted on the Algoa V241, 12 July to 11 August, 2017. The area covered includes the Transkei shelf and continental slope (20m to 1000m), of the Eastern Cape, between Cape St Francis and Port Shepstone in the South-West Indian Ocean.Our knowledge of the distribution of offshore benthic biodiversity on the Transkei shelf is very limited. The region between Algoa Bay and Port Edward is not only important for understanding the functioning of existing Marine Protected Areas (MPAs) such as Pondoland, Dwesa-Cwebe, and the Amathole, but is of particular relevance to the new Operation Phakisa proposed MPA network that will potentially include additional MPAs such as the Protea Banks, Amathole Expansion, and the proposed Addo MPA. In addition, further knowledge is needed to support decision-making about the offshore extent of the Dwesa-Cwebe MPA. The oceanography in the form of water column and energy characteristics, circulation regimes and...

St Helena Bay Monitoring Line (SHBML) on the Algoa Voyage 194, February 2013

The St Helena Bay Monitoring Line, which now falls under the Integrated Ecosystem Programme: Southern Benguela, was conducted on the Algoa Voyage 194, 11 to 15 February 2013. The St Helena Bay Monitoring Line was initiated as a BENEFIT-driven project on "shipboard monitoring" which linked with similar lines run in Namibia and Angola. The aims are to obtain seasonal and interannual information on the hydrology and productivity of the area. Data on harmful algal blooms, low oxygen water and intrusions of Agulhas Bank water along the west coast will also be collected. A long-term, multi-decadel time-series (from 1951 onward) of information already exists for this important region and has continued in the form of the IEP:SB to detect long-term changes in the hydrology and the plankton, which are important for the detection of regime shifts.
