Chlorophyll a concentration was determined by filtering 1 L of seawater through 47 mm diameter Whatman GF/F filters, which were immediately added with 10 ml of methanol and stored in 4 degree Celsius refrigerator for 8 to 24 hours. Samples were taken every 4 hours. Seawater was also collected and preserved in Lugol's iodine and brought back to University of Tasmania where species identification will be carried out. Measurement of phytoplankton parameters and chlorophyll a concentration were carried out on both south and northbound transects. Once a day the data from the FRRF was uploaded to computer and the lenses of the FRRF were cleaned. Laboratory activity/analysis: Chlorophyll determinations using a Turner 10AU Fluormeter and ...
