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

This is Scientific Data System (SDS) 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...

Long-term monitoring of seawater temperature in the microhabitats of intertidal marine invertebrates in Sea Point, South Africa

To better understand the physiological effects of marine invertebrates to changing environmental conditions, long-term monitoring which captures the natural variability of environmental parameters is required. In this way, experimental findings can be related back to field conditions, and better predictions can be made as to how marine invertebrates, particularly in the harsh intertidal, will fair with rising temperature. In May 2020, Cape Sea Urchins, Parechinus angulosus, were collected from intertidal rock pools at Sea Point, which is situated along the southwest coast of South Africa. After chronic incubation in low pH conditions at the Department of Forestry, Fisheries and the Environment (DFFE) Sea Point Research Aquarium, their response to thermal stress was investigated in recent experimental trials. To calculate the thermal window for these marine invertebrates, both habitat temperatures, as well as their threshold temperatures are required. The latter was obtained by...

Processed XBT data from the Southern Ocean Seasonal Cycle Experiment (SOSCEx) III Winter Cruise on the SA Agulhas II Voyage 016, July 2015

This is processed Expendable Bathythermograph (XBT) data from the Southern Ocean Seasonal Cycle Experiment (SOSCEx) III Winter Cruise on the SA Agulhas II Voyage 016, 22 July to 15 August, 2015. The third Southern Ocean Seasonal Cycle Experiment (SOSCEx) III is a high-resolution full seasonal cycle experiment using integrated observational and modeling platforms. A novel aspect of SOSCEx III is the integrated multi-platform approach, which aims to explore new questions about the climate sensitivity of carbon and ecosystem dynamics in the Southern Ocean and how these processes are parameterized in models. This winter 2015 cruise can be divided into two primary tracks, the GoodHope line, between Cape Town and the ice edge along the Greenwich Meridian, and the South Atlantic Meridional Overturning Circulation Basin-wide Array (SAMBA) line, between Cape Town and the Greenwich Meridian, at 34.5 degrees South longitude.

Processed underway Thermosalinograph (TSG) observations from SA Agulhas II Voyage 061, December 2023 - February 2024

Here we present the 6-second resolution processed Thermosalinograph (TSG) data collected, between 26 December 2023 and 20 February 2024, during voyage 061 on the SA Agulhas II. 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).
