Our oceans are increasingly under stress. Climate change and unchecked activities pose a real threat to the ecological health of the world’s oceans. By 2025, Australia’s marine industries will contribute around $100 billion each year to our economy, with our oceans and coasts providing a further $25 billion worth of ecosystem services, such as carbon dioxide absorption, nutrient cycling and coastal protection. A blue economy is one which strikes the right balance between reaping the economic potential of our oceans with the need to safeguard their longer-term health, bringing economic and social benefits that are efficient, equitable and sustainable.
Three hypothesis of change in the SE Australian Marine Ecosystem are being explored by the survey:
Observed impacts to the ecosystem, fish communities and benthic habitat over the past 30 years have been driven by exposure to bottom-contact fishing: The Habitat Hypothesis
Observed impacts to the ecosystem, fish communities and benthic habitat over the past 30 years driven by changes to the water column driven by changing ocean conditions: The Climate Hypothesis
Interactions of these two impacts are being seen through changes to the food web: The Trophic Hypothesis
SEA-MES also has a series of projects contributing to science benefit and capacity building:
