Microplankton image observations for August 2019 on the Integrated Ecosystem Programme: Southern Benguela (IEP:SB)

Microplankton, comprising both phyto- and zooplankton in the 20-200μm size range, are a diverse and ecologically significant group. They form the foundation of the food web, are instrumental in carbon and nutrient cycling, generate at least 50% of global oxygen and facilitate the transfer of energy to higher trophic levels. Although microplankton occur throughout the world's oceans, their diversity and abundance varies spatially and temporally. Due to their high sensitivity and rapid response to changes in the environment, their biomass and diversity are considered Essential Ocean Variables (EOV's) for routine and sustained long term observations to assess global ocean changes. This dataset forms part of the routine monitoring along the west coast of South Africa under the Integrated Ecosystem Programme: Southern Benguela, which occurs biannually in February and August. This resource contains raw image data for August 2019 obtained from water samples processed using a FlowCam VS3...

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

This is raw Surface Photosynthetically Active Radiation (SPAR) 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.

Microplankton monitoring along the west coast of South Africa

Microplankton, comprising of both phyto- and zooplankton in the 20-200μm size range, are a diverse and ecologically important group. They form the foundation of the food web, are instrumental in carbon and nutrient cycling, generate at least 50% of global oxygen and facilitate energy flow to higher trophic levels. Although they are found in all oceans globally, their diversity and abundance is varied. Due to their high sensitivity and rapid response to changes in the environment, their biomass and diversity are considered Essential Ocean Variables (EOV's) for routine and sustained long term observations to assess global ocean changes. This dataset forms part of the routine monitoring along the west coast of South Africa - Integrated Ecosystem Programme: Southern Benguela which occurs biannually in February and August.

Processed imagery data collected off the western margin's deep-sea environment on Algoa Voyage 246, February 2018

The aim of the Integrated Ecosystem Program (IEP) Benthic Project is to establish a baseline for epi-benthic invertebrate distribution, in order to identify benthic indicators for long-term monitoring within the pre-determined IEP monitoring lines. Ten stations were successfully surveyed, on board the R/V Algoa in February 2018, using a towed under-water benthic camera. The acquired abundance data represents five stations from the Kleinsee transect, four from Namaqua and one from St Helena Bay.
