Chlorophyll a and Phaeophytin concentrations are measured fluorometically using a Turner designs 10AU fluorometer after grinding the filters in 90% acetone [Parsons, T.R., Maita,Y. and Lalli, C.M. (1984). A Manual of chemical and Biological Methods for Seawater Analysis. Oxford, Pergamon Press]. The concentration of primary standard used for calibration is determined spectrophotometrically using the equations laid out in the paper by Jeffrey, S.W. and G.F. Humphrey, (1975), New Spectrophotometic equations for determining chlorophylls a, b, c1 and c2 in higher plants, algae and natural phytoplankton. Biochem Physiol.

The chlorophyll monitoring has been managed by the Australian Institute of Marine Science since 1999 and is an important part of the AIMS water quality research and monitoring activities. Since 2005, the Chlorophyll Monitoring is a component of the Reef Plan Marine Monitoring Program, a responsibility of the GBRMPA under the Reef Water Quality Protection Plan. Sample analysis and data management has been undertaken by AIMS. The Great Barrier Reef (GBR) is the largest contiguous coral reef ecosyste
