Darwin Harbour Integrated Marine Monitoring and Research Program

Habitat monitoring focuses on the mangroves.

It makes use of satellites and drones to watch mangrove extent and condition.

• Review of research and monitoring of Darwin Harbour’s mangrove environment for the development of a long-term monitoring program.

Seafloor sediments are monitored across Darwin Harbour.

Checks are done to see if pollutant concentrations are higher than they should be due to widespread human activities.

They monitor to see if any changes are occurring in concentrations of the following:

• metals and metalloids
• hydrocarbons
• other constituents.

This program shouldn’t be confused with compliance monitoring programs. These programs are done to ensure that a regulated body conforms to:

• environmental laws
• regulations
• standards.

Read more about compliance and regulation on the NTEPA website.

It builds on the department’s ongoing work to look after the water quality.

The department also publishes an annual Darwin Harbour Report Card.
