Samples were collected from the locations Two Rocks (Feb 2002 - Dec 2004), Bunbury and Jurien Bay (March 2003 - Feb 2005) and analysed for total suspended matter, absorption coefficients for dissolved and particulate matter and pigment concentration and composition. Microphytobenthos samples were collected at sites where Martin Lourey worked.
The Two Rocks data were collected at 5 stations on the Two Rocks transect as used during the SRFME project. The data were collected by two groups; one group sampled 5 stations from A (20 m depth), B, C, D to E (1000 m depth). The second group sampled 5 stations - T2, T3, T4, T5 and T6 where T3 was equivalent to station A and T6 was equivalent to station B. The data were collected to determine the bio-optical charateristics of this region. The data can be used for Ocean Colour sensor validation. Parameters measured are the concentration of chlorophyll and carotenoid pigments, These samples were analysed using the method of Wright et al 1991.
