Ichthys Gas Field Development - Marine Water and Sediment Quality Study.

The aim of the marine and sediment quality studies is to characterise the baseline condition (natural status) of the sediments and waters at the Ichthys Field, along the proposed pipeline route and at the Maret Islands. Objectives The objectives of the marine and sediment quality studies are to: 1. Identify sensitivities of the receiving environment; 2. Quantify the baseline status of the receiving waters and sediments in the development areas; 3. Characterise the physico-chemistry of the sediments; 4. Measure contaminant concentrations in potential bio-accumulating organisms; 5. Determine if there are any abnormal existing levels in water quality that may already exceed the National Water Quality Management Strategy guidelines; 6. Measure seasonal changes in water quality associated with natural events; 7. Provide physical water quality data for validating the hydrodynamic model; and 8. Provide baseline information for the spatial establishment of ecological protection levels.
