Brief description

This data was collected to improve our knowledge and understanding of the marine environment in the upper reaches of East and Middle Arms (Darwin Harbour), to assist planning and sustainable development for the new township. Data provide polygon data that map the benthic habitats (12 physical and biological categories) in the upper reaches of the harbour using remote-sensed and survey data. This dataset is being continually updated and is current as of 03/03/2016.
