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

description: Algoa Voyage 282
description: 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 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 Benguela. These include physical, chemical, planktonic, microbial, seabird, marine mammal, benthic and pollution (plastic) ecosystem indicators as required by ecosystem-based management regarding the following priorities: ocean warming, ocean acidification, trophic functioning, pollution and water quality. It is on-going monitoring programme.
description: The SeaBird SBE45 Thermosalinograph (TSG) is used on the Algoa for the collection of underway near-surface temperature and conductivity measurements. The underway seawater is obtained from a depth of 5m 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 data processing software. The software was set to record data at 6 second intervals for the duration of the cruise, between10 May 2022 and 18 May 2022. Data was collected in the southern part of the Benguela Current Large Marine Ecosystem (BCLME) region on the west coast of South Africa. Unreliable TSG measurements can result from a variety of problems encountered during the cruises, including insufficient water flow, extreme air bubbling during severely 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: Integrated Ecosystem Programme: Southern Benguela (IEP:SB) on the Algoa Voyage 218, September 2015

description: This St Helena Bay Monitoring Line cruise was conducted in September 2015 (now under the Integrated Ecosystem Programme: Southern Benguela). 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.

title: Northern Benguela shelf and open ocean seasonal mean chlorophyll a time series, 1997 to 2018

description: Northern Benguela shelf and open ocean seasonal mean chlorophyll a time series, 1997 to 2018
description: Reconstructed seasonal mean chlorophyll a (mg m-3) for SeaWiFS and MODIS-Aqua in the Northern Benguela (15-29°S;8-16.8°E) shelf and open ocean regions during austral summer, autumn, winter, and spring. Shelf and open ocean regions have been separated using the GEBCO 1000m isobath.
description: Standard monthly-averaged SeaWiFS and MODIS-Aqua Chlorophyll a concentrations, with a spatial resolution of 9km, were used to generate seasonal means of chlorophyll a for the Northern Benguela shelf and open ocean regions. The shelf and open ocean regions were separated using the 1000m GEBCO isobath. Seasonal means were computed by averaging data over a three-month period for each season, defined as austral summer (December, January, February), autumn (March, April, May), winter (June, July, August), and spring (September, October, November). Using the MODIS-Aqua data as the reference dataset, the SeaWiFS values were reconstructed (predicted) within the framework of a Generalized Linear Model, in order to remove the systematic bias between SeaWiFS and MODIS-Aqua values. This data has been processed and published as Lamont et al. (2019) JGR Oceans, 124, 1170-1195 (https://doi.org/10.1029/2018JC014334) - please see this paper for a more detailed methodology.

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

description: 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 well-functioning ocean environment. The overarching objective is to enhance understanding in process studies by assessing the importance, timing and magnitude of mechanisms and processes that influence the Southern Benguela ecosystem structure and functioning, including the climate variability.

title: Processed grab camera data to investigate substrate categories associated with benthic invertebrate fauna of the Southern Benguela Ecoregion on the Algoa Voyage 263, August 2019

description: This is processed grab data from the Southern Benguela Cruise, which was conducted in the Southern Benguela Ecoregion on the Algoa Voyage 263, August 2019. This study focuses on providing a better understanding of the benthic invertebrate communities and associated habitats of three priority areas within the southernmost portion of the Southern Benguela Ecoregion. This includes Robben Island, the Table Mountain National Park Marine Protected Area (TMNP MPA) and the newly proposed Seas of Good Hope Ecologically and Biologically Significant Area (EBSA). The aims are: 1) To contribute to the first baseline assessment for continuous long-term monitoring. 2) To determine the species diversity of benthic invertebrate communities, and how geological (i.e habitat type) and physical factors (i.e. location, depth) may be responsible for driving their distribution and abundance. 3) To verify habitat types: Verification of the habitats associated with physical features (e.g. geological substrate) by means of in situ sampling of the seabed (using a dredge or grab) and underwater visual assessments (using benthic cameras). 4) To provide legitimate conservation rationale for the establishment of the Seas of Good Hope EBSA and possible expansion of the TMNP MPA.
