A geochemical investigation of the Darling and Ysterfontein saline pans, Western Cape, South Africa
Saline pans are an important component of the hydrologic cycle in arid areas, and are common in South Africa. Natural saline pans on the coastal lowlands of the Western Cape Province, South Africa, were studied to determine the origin and evolution of salts within the pans. Samples of surface, …

A geochemical investigation of the water and sediments of Barber's Pan, North West Province
Pans comprise a large proportion of southern African wetlands and yet remain poorly classified. Very little data is available on the aqueous chemistry of southern African saline systems, and with the exception of a few publications dealing, in part, with the soil and associated materials of pan …

Marine algal virus communities along Southern African coasts
… illicit these events. In addition, solar salt - pans located on the coast that draw their water from the bay area are affected by bloom events. Algal viruses play a key role in regulating phytoplankton communities and modulate the dynamics of these bloom events. Identifying the viruses associated …
