Estuaries are widely viewed as hotspots of primary productivity. The Coorong in South Australia is an inverse estuary divided into two lagoons, extremely important to the associated riverine, lacustrine and marine environments and characterized by a steep, lateral salinity gradient. Here, we analyzed the abundance and distribution of primary producers over two years (August 2011-2013) and investigated the biogeochemical factors driving observed changes. The phytoplankton community was numerically dominated by chlorophytes in the North Lagoon with Chlorohormidium sp. and Oocystis sp. being the most abundant species. In the South Lagoon, diatoms dominated the community, with Cylindrotheca clos..
