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...
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.

West Coast Cetacean Distribution and Abundance Survey on the Ellen Kuzwayo Voyage 126, October 2014
This West Coast Cetacean Distribution and Abundance Survey was conducted on the Ellen Kuzwayo Voyage 126, from 28 October to 10 November, 2014. The survey was planned for the region between Dassen Island and Groenriviermond up the west coast. The cruise track of the Ellen Kuzwayo is closely linked to that of the Algoa and while the latter was engaged in offshore and onshore parallel tracks up to the 250m isobaths, the former ran a saw tooth grid survey starting inshore Dassen Island (moving...
