Samples were analysed and QC procedures were carried out in the Ocean Colour Laboratory. Pigment analysis 4 litres of sample water was filtered through a 47 mm glass fibre filter (Whatman GF/F) and then stored in liquid nitrogen until analysis. To extract the pigments, the filters were cut into small pieces and covered with 100% acetone (3 mls) in a 10 ml centrifuge tube. The samples were vortexed for about 30 seconds and then sonicated for 15 minutes in the dark. The samples were then kept in the dark at 4 °C for approximately 15 hours. After this time 200 µL water was added to the acetone such that the extract mixture was 90:10 acetone:water (vol:vol) and sonicated once more for 15 minutes. The extracts were centrifuged to remove the filter paper and then filtered through a 0.2 µm membrane filter (Whatman, anatope) prior to analysis by HPLC using a Waters Alliance high performance liquid chromatography system, comprising a 2695XE separations module with column heater and refrigerated autosampler and a 2996 photo-diode array detector.

The separated pigments were detected at 436 nm and identified against standard spectra using Waters Empower software.

Brief description

This record contains data collected on the RV Southern Surveyor, between November 26 and December 12 2005. The data were collected across two legs. Leg 1 samples were collected between Fremantle and a position east of Albany, and Leg 2 samples were collected between Fremantle and Dampier. The data can be used for Ocean Colour sensor validation. Parameters measured are the concentration of chlorophyll and carotenoid pigments and retrieved chlorophyll a estimate of the water column. 9 stations were sampled and data was also recorded at 7 underway locations. Samples were collected and analysed for pigments.
