Site Description
The Algoa Bay Sentinel Site is a coastal observatory comprising four programmes and a geographical footprint spanning >300 km of coastline on the warm-temperate south-east coast of South Africa. The Continuous Monitoring Programme (CMP) comprise 37 permanently moored in situ observatories measuring a series of physical properties of the coastal ocean between Port Alfred and Oyster Bay. The Pelagic Ecosystem LTER Programme (PELTER) perform long-term observations selected Essential Biodiversity Variables (EBV), including phytoplankton and zooplankton. The Sandy Beaches LTER Programme (SBLTER) entail observations of short- and long-term changes in surfzone diatoms among other variables at 10 sandy beach stations in Algoa Bay. The ...
