Pre-processed SADCP data for the South Atlantic Meridional Overturning Circulation Basin-wide Array (SAMBA) Monitoring Line in the South-East Atlantic Ocean on Algoa Voyage 210, September 2014

This is pre-processed Shipboard Acoustic Doppler Current Profiler (SADCP) data for the South Atlantic Meridional Overturning Circulation Basin-wide Array (SAMBA) Monitoring Line in the South-East Atlantic Ocean on Algoa Voyage 210,15 to 29 September, 2014. This cruise had a primary scientific objective of extending the SAMBA mooring line, the offshore section of the Cape Point long-term monitoring line, and deploying the four offshore tall moorings. This dataset was processed using older standards which may not align with international best practices and the standards currently adhered to by the Department of Forestry, Fisheries and the Environment (DFFE). The Department is re-processing and replacing data to ensure everything has the same format and is of the same quality and datasets will be marked as obsoleted once that is done. As such the user assumes the entire risk related to the use of these data in its current state and format. DFFE disclaims all warranties of the data...

Long-term observations of hourly bottom temperatures at Hout Bay, South Africa

Here we present a collection of raw and processed temperatures from Underwater Temperature Recorders (UTRs) located off Hout Bay, South Africa. At selected sites around Southern Africa, UTRs have been used to obtain long-term records of bottom temperatures in the nearshore environment, at depths ranging from 2m to 34m.

Processed underway Thermosalinograph (TSG) observations from Algoa Voyage 293, August 2023

Here we present the 6-second resolution processed Thermosalinograph (TSG) data collected, between 15 August and 22 August 2023, during voyage 293 on the RS Algoa. 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).

Raw TSG data from the West Coast Cetacean Distribution and Abundance Survey on the Algoa Voyage 211, October 2014

This is raw Thermosalinograph (TSG) data collected on the West Coast Cetacean Distribution and Abundance Survey on the Algoa Voyage 211, 28 October to 10 November 2014. The cruise operated on the shelf and slope regions off the West Coast of South Africa, between Dassen Island and Groenriviermond.The major objective of this cruise was to survey the abundance and distribution of cetaceans, in particular humpback whales, within the study area on the west coast. This objective, along with the research aims and proposed methodologies, are consistent with internationally accepted protocols. This work provided hands-on experience with logistical and technical cetacean specific problems associated with dedicated cetacean cruises. This work was a collaboration with the Mammal Research Institute, University of Pretoria, and the Department of Agriculture, Fisheries and Forestry.

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 SADCP data from the Integrated Ecosystem Programme: Southern Benguela (IEP:SB) on the Algoa Voyage 218, September 2015

This is raw Shipboard Acoustic Doppler Current Profiler (SADCP) data from the St Helena Bay Monitoring Line September 2015 cruise (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.

Pre-processed chlorophyll-a data from the Integrated Ecosystem Programme: Southern Benguela (IEP:SB) on Algoa Voyage 220, November 2015

This is pre-processed chlorophyll-a data from the Integrated Ecosystem Programme: Southern Benguela on Algoa Voyage 220, 18 - 25 November 2015. The Integrated Ecosystem Programme: Southern Benguela 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.
