The biogeochemistry laboratory in the Oceanography department at UCT performs routine hydrographic measurements such as nutrient concentrations (NO3, NO2, NH4, SiO4, PO4, urea), dissolved oxygen, chlorophyll and pH. An automated system (flow injection auto-analyser) is available for NO3, SiO4 and PO4 analyses while NH4 is determined fluorometrically. All of the above nutrient concentrations can beRead More..
