Petrel Sub-basin Marine Survey (GA-0335 / SOL5463) (NLECI Program) - Seabed Geochemistry / Chlorophyll abc and pheaophytin
The Petrel Sub-basin Marine Environmental Survey GA-0335, (SOL5463) was undertaken using the RV Solander during May 2012 as part of the Commonwealth Government's National Low Emission Coal Initiative (NLECI). The survey was undertaken as a collaboration between the Australian Institute of Marine Science (AIMS) and GA. The purpose was to acquire geophysical and biophysical data on shallow (less then 100m water depth) seabed environments within two targeted areas in the Petrel Sub-basin to support investigation for CO2 storage potential in these areas. This 10 sample dataset comprises chlorophll abc measurments from surface sediments (0-2 cm) in the Timor Sea.

Bottom sediments were collected using a Smith McIntyre grab. 0.4 ml samples of surface sediment (0-0.5 cm) were syringed into plastic bags. The samples were wrapped in Al foil and frozen. Chlorophyll concentrations were calculated on sediment extracts (90% acetone + 0.1% MgCO3) at spectrophometric readings at wavelengths of 647, 630, 750 and 664 nm. For chlorophyll-a (Chl-a) and phaeophytin-a, wavelengths of 664 nm and 750 nm (before and after the addition of 200 -L-1 0.1 mol L-1 HCl per 2 mL extractant) and the equation derived by Lorenzen (1967) were used. Chlorphyll b and c concentrations were calculated according to equations provided by Jeffrey and Welschmeyer (2003).

The reproducibility of the measurements was +/-10%.
