Abstract

Estuaries are productive and delicate marine systems, which are of commercial, recreational and aesthetic value as they reflect the land use of a catchment by creating “nutrient traps”, these nutrients are absorbed by water and later released into the coastal oceans. Disturbances in an estuary influence a wide variety of habitats and organisms in a marine ecosystem, for example, high chlorophyll-a affects marine species that utilize calm waters, food and turbid water found in estuaries. The degradation of South African estuaries is an on-going accelerating process; therefore, there is a need for preservation measures for estuarine ecosystems by means of monitoring nutrient flow. This research was aimed at assessing the use of OLCI ocean col...
