Processed underway Thermosalinograph (TSG) observations from the Algoa Voyage 257, January 2019

Here we present the 6-second resolution processed Thermosalinograph (TSG) data collected between 08 January 2019 and 25 January 2019 on the RS Algoa Voyage 257. 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).

Raw TSG data from ACEP Deep Secrets: The Outer Shelf and Slope Ecosystems of the Eastern Cape on the Algoa Voyage 230, September 2016

This is raw Thermosalinograph (TSG) data collected on the ACEP Deep Secrets Cruise which set out to fill in gaps and shed light on the priority areas and research questions identified during the recent Marine Protected Area and Marine Spatial Planning Initiatives of Operation Phakisa’s Marine Protection and Governance Lab. Using underwater cameras (SkiMonkey and Drop camera), grabs, dredges and a CTD the study aimed to improve our knowledge on marine offshore habitats, as well as to build understanding of the effects of the expanding fishing and petroleum industries on marine offshore communities.

Raw TSG data from the South Coast Moorings and Monitoring Lines Cruise on the Algoa Voyage 213, December 2014

This is raw Thermosalinograph (TSG) data from the South Coast Moorings and Monitoring Lines Cruise on Algoa Voyage 213 on 1 to 19 December, 2014. Between 1988 and 2011, environmental and plankton sampling was conducted every summer along the South Coast during the annual pelagic spawner biomass surveys. Data collected during these cruises has provided valuable insight into environmental change in this region. There has been significant decline in copepod biomass on both the western and central Agulhas Bank over the past two decades, as well as a decline in the proportion of the large dominant species Calanus agulhensis, resulting in a shift towards a smaller copepod-dominated community. These changes are thought to have been largely driven by predation by planktivorous fish, which have increased in biomass since the mid-1990s, but increasing sea temperatures have also played a role. It is vital that we continue to monitor the environment and plankton community in key areas off the...

Raw TSG data from the South Coast Mooring Cruise on the Algoa Voyage 208, July 2014

This is raw Thermosalinograph (TSG) data collected on the South Coast Mooring Cruise on the Algoa Voyage 208, 9 to 24 July 2014. The South Coast Mooring Cruise had two scientific objectives: (1) Service, maintain and extend the in situ operational oceanography network currently deployed around South Africa and (2) to investigate the dynamics of the Port St Johns eddy and biological implications. Between 1988 and 2011, environmental and plankton sampling was conducted every summer along the South Coast during the annual pelagic spawner biomass surveys.
