The dataset covers the north-northwest region of the Australian continental EEZ. This dataset supersedes previous predictions of seabed sand content for the region with demonstrated improvements in accuracy. Accuracy of predictions varies based on density of underlying data and level of seabed complexity. Artefacts occur in this dataset as a result of insufficient samples in relevant areas. This dataset is intended for use at regional scale. The dataset may not be appropriate for use at local scales in areas where sample density is insufficient to detect local variation in sediment properties. To obtain the most accurate interpretation of sediment distribution in these areas, it is recommended that additional samples be collected and interpolations updated.

The survey was undertaken under the Australian Government's National CO2 Infrastructure Plan (NCIP) to help identify sites suitable for the long term storage of CO2 within reasonable distances of major sources of CO2 emissions. The principal aim of the Leveque Shelf marine survey was to look for evidence of any past or current gas or fluid seepage at the seabed, and to determine whether these features are related to structures (e.g. faults) in the Leveque Shelf area that may extend to the seabed. The survey also mapped seabed habitats and biota to provide information on communities and biophysical features that may be associated with seepage.

Solander between 30 July and 30 September 2010 in collaboration with staff from the Australian Institute of Marine Science (AIMS) and the Museum and Art Gallery of Territory (MAGNT). This was a follow up survey from a survey in 2009 (SOL4934, GA0322). The aims of the survey were to map, identify and investigate potential geohazards and unique, sensitive environments that relate to infrastructure; and to use existing data to evaluate the capacity to predict geohazards and sensitive environments.
