Marine Hazard Mapping
The Crocodile Islands Rangers (CIR) have been working on a project with Geomancia, to produce a map that shows marine hazards in the area.
The Rangers patrol and manage a large area of coastal northern Australia, principally in the vicinity of Castlereagh Bay (nautical charts Aus 16 and Aus 717). The coastal waters in this area are unsurveyed, and there are many marine hazards including unmapped submerged rocks, reefs and sandbars.
We are mapping hazards in our sea country to increase the safety of sea operations by both the Ranger group and other visitors to these seas, and have been recording marine hazard areas on our sea patrols, as well as taking aerial photos of the area.
Geomancia has been working with the CIR to improve our access to spatial information and to produce a detailed map. We would also like to acknowledge and thank Territory Natural Resource Management and the Northern Land Council for their help with this project.
We are keen to share this map with other users of these coastal waters, and have attached a higher quality version of this Sea Country Hazards Map on our Resources page. We will continue to update and improve our hazard mapping, so keep an eye out for updated maps.
