title: Processed underway Thermosalinograph (TSG) observations from the Integrated Ecosystem Programme: Southern Benguela (IEP:SB) on the Algoa Voyage 262, August 2019

description: 6-second resolution processed Thermosalinograph (TSG) data between 13 August 2019 and 19 August 2019 during the Integrated Ecosystem Programme: Southern Benguela (IEP:SB) on the RS Algoa Voyage 262
description: Here we present the 6-second resolution processed Thermosalinograph (TSG) data between 13 August 2019 and 19 August 2019 during the Integrated Ecosystem Programme: Southern Benguela (IEP:SB) on the RS Algoa Voyage 262. A SeaBird SBE45 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 programme is a multi-disciplinary, multi-institutional platform undertaking relevant science in the Southern Benguela; it also functions 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. These include physical, chemical, planktonic, microbial, seabird and benthic ecosystem indicators, used for ecosystem-based management.
description: The SeaBird SBE45 Thermosalinograph (TSG) is used on the RS 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, between 13 August and 19 August 2019. 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: Benguela Air-Sea CO2 and Heat Flux Experiment on the Algoa Voyage 278, December 2021

description: The Benguela Air-Sea CO2 and Heat Flux Experiment was conducted on the Algoa Voyage 278 from 6 to 19 December 2021. 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 wind. The objectives of the cruise were to examine, using high-resolution Eddy Co-Variance (EcV) and in situ observations, the role of the ocean “cool skin” on the air-sea flux of CO2 and heat; to examine, through high-resolution observations, the impact of the vertical temperature gradient in the upper 10m of the water column on the estimation of the air-sea flux; to examine the sensitivity of 1 and 2 under a wide range of diurnal and synoptic wind stress and surface layer mixing conditions; to link the variability in the temperature gradients and pCO2 to mixed layer dynamics in response to the interaction of wind-linked mixing and heat-linked stratification; to understand the synoptic scale variability of the CO2 and heat fluxes; to understand how synoptic scale influence diurnal variability of Dissolved Inorganic Carbon (DIC) and Total Alkalinity (TA); to investigate how representative the bulk heat flux parameterisations are to the true EcV heat fluxes, particularly over sharp lateral temperature gradients; to determine the respective role of fine-scale lateral oceanic processes (submesoscales) and synoptic atmospheric variability to the leading order variability of surface heat fluxes and to conduct Top predator population including Seabirds, whales, dolphins, seals, etc.

title: Deployment of acoustic listening moorings on the Algoa Voyage 297, January 2024

description: South Africa’s developing Oceans Economy Master Plan has increased the range, extent, and intensity of anthropogenic pressures on marine and coastal biodiversity. Activities such as offshore oil and gas exploration, marine transport, small harbour and infrastructure development, and marine tourism have led to elevated noise levels in the ocean and coastal environment. These increased noise levels may negatively impact marine biodiversity and ecosystem services, yet their effects are not yet fully quantified for South Africa's marine regions. To address this, a study was conducted on Algoa Voyage 297 in January 2024, deploying three acoustic recorders along the west coast of South Africa to capture long-term recordings of the marine soundscape. Deployment locations included Namaqualand MPA, Childs Bank MPA, and offshore of the Orange River, aiming to characterise the marine soundscape and assess its impact on marine biodiversity and ecosystem health.

title: West Coast Cetacean Distribution and Abundance Survey on the Algoa Voyage 266, November 2019

description: The West Coast Cetacean Distribution and Abundance Survey was conducted on Algoa Voyage 266, from 04 November to 15 November 2019. The cruise operated along the shelf and slope regions of the West Coast of South Africa, spanning from Dassen Island to Groenriviermond. The primary objective was to assess the distribution and abundance of cetaceans, particularly humpback whales, in the study area. This work adhered to internationally accepted protocols and provided practical experience in addressing logistical and technical challenges associated with dedicated cetacean research cruises.

title: Commissioning of EIVA ScanFish on the Algoa Voyage 298, January 2024

description: In November 2018, the EIVA ScanFish III undulator and winch system was acquired, equipped with multiple physical and chemical sensors for real-time data collection. Initial commissioning and training trials were conducted aboard Algoa in December 2018 (ALG256). However, due to instrument damage, these trials were not fully completed. After repairs, additional commissioning trials were carried out during Algoa Voyage 298 in January 2024 to ensure full functionality and operational reliability of the system.

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.
