Raw Seaglider data collected during GINA 2017 by Seaglider SG574
The Gliders IN the Agulhas (GINA) project is a multi-institutional effort to implement sustained glider observations around South Africa’s coastline to enhance existing regional networks and complement larger international observations systems such as the Ocean Gliders Boundary Ocean Observing Network (BOON). Ocean gliders are robotic platforms operated and piloted from land. The Seaglider during GINA was set-up to vertically profile the water column between depths of 0 and 1000m....
Wirewalker wave-powered profilers from three nearshore moorings in St Helena Bay, South Africa, Feb-Apr 2011
Concurrent nearshore measurements of temperature, salinity, and chlorophyll fluorescence from three moorings offshore of Elands Bay, within St Helena Bay, Southern Benguela, in water depths of ~22 m (mooring 3), ~50 m (mooring 2) and ~62 m (mooring 1). The data were originally presented in "Lucas, A. J., Pitcher, G. C., Probyn, T. A., & Kudela, R. M. (2014, March). The influence of diurnal winds on phytoplankton dynamics in a coastal upwelling system off south -western Africa. Deep Sea...
Benthic invertebrate presence data, in and around the Cape Canyon (Southern Benguela Upwelling region)
Canyon research is still an emergent field in South Africa and the true potential of canyons as biodiversity hotspots has seldom been studied in an integrated context. In response to this, the Department of Forestry, Fisheries and the Environment: Oceans and Coasts collected benthic data to better understand benthic species profiles within and around the Cape Canyon. This equated to 39 stations (whereby 13 were canyon and 26 non-canyon) and yielded 180 species.
Anchovy Recruitment Survey on the Africana Voyage 092, May 1991
The Anchovy Pilchard Recruitment Survey on the Africana Voyage 092 was conducted on the 7 to the 24 May 1991. The main objectives of the cruise were to estimate the abundance and size-structure of anchovy; a description of the distribution and behaviour patterns of anchovy and pilchard of recruits and the oceanographic variables on these; a collection of biological data on pelagic fish species; an examination of the distribution, abundance and production of plankton in relation to the...
Experimental manipulations of the density of Cymbula granatina on rocky shore community
Densities of a commonly-harvested intertidal limpet Cymbula granatina were manipulated at two sites within a no-take marine protected area on the west coast of the Cape Peninsula in South Africa, using four treatment levels ranging from zero to maximum natural densities, together with control plots, to evaluate the effects of different harvesting intensities on rocky shore community composition. Following removal or thinning of C. granatina, community composition changed: cover of corticated...
Annual State of the Oceans reports
A series of reports on State of the Oceans around South Africa, produced by Branch Oceans and Coasts of South Africa’s Department of Environmental Affairs, was introduced in December 2006. The reports initially considered environmental parameters for the purposes of establishing general principles, such as annual cycles, and long-term trends, which may provide insight into the local effects of global warming and climate change. The reports were intended to provide an overview of marine...
