Water flowing along the sediments (mud, sand, gravel, rocks) that make up the ocean floor can move them (sediment transport) given sufficient energy (shear stress).   Essentially, when the force of water flowing against a sediment is greater than the gravitational force holding it in place, the sediment begins to move.  The magnitude of shear stress required to cause sediment transport depends on the sizes and types of sediments present in a given location.

The topography of the seafloor can play a major role in determining what types and abundance of organisms can survive there as it controls water circulation (read how it works).  One of the most common measures of topography is the slope - the rate of change of depth with distance (rise over run).

Turbidity is a measure of the cloudiness of water caused by suspended particles (so small that they are usually invisible to the naked eye) that limit the transmission of light through the water.

Much of life on earth ultimately depends on the capture of energy from the sun and its translation into energy via photosynthesis.  The relative extent to which this (primary production) occurs is a useful measure by which to compare the biological activity of regions.

Use the interactive map below to see the relative distance of the Oceanic Shoals CMR from shore compared to other CMRs.   Click on the four-arrow icon to activate the interactive map.  You then click on the 'Commonwealth Marine Reserve boundaries' data layer to see how the Oceanic Shoals compares to the other CMRs.

Geomorphology is a major driver of the type and abundance of organisms living on and near the sea floor.  Much work has been done to define and characterise ocean geomorphology at spatial scales ranging from the entire world's oceans to the NW Australian region.

Sea surface temperature is the measure of how hot or corld the water in the ocean is at a given time and place.  Ocean organisms have adapted to certain levels of sea temperature and can be harmed if the water is too much warmer or colder than normal (for example, this can cause coral reefs to bleach).

Salinity is the measure of how much salt is in the ocean at a given time and place (why is the ocean salty?).  Ocean organisms have adapted to certain levels of salinity and can be harmed if salinity changes too much from typical levels (for example, low salinity in flood plumes can stress coral reefs).

The Integrated Marine and Coastal Regionalisation of Australia (IMCRA v4.0) classified Australia's marine environment into ecologically relevant bioregions for regional planning. These bioregions are the basis for the development of a National Representative System of Marine Protected Areas (NRSMPA).

Coral reefs support a diverse array of life, including hard and soft corals, sponges, macroalgae and fish.

Australia’s marine industries are worth more than $50 billion a year.  Oil and gas is the largest single contributor to Australia’s marine economy (see report), with most major global companies represented.

Seismic surveys have been used extensively in Australia by Geoscience Australia to map undersea geology and by various companies exploring for oil and gas deposits, particularly on the NW shelf (for example, at Scott Reef in 2007).

Surprisingly common across the world's oceans, bioluminescence (watch a video of how it works) occurs when a chemical reaction in living cells causes them to emit light - typically in shades of blue and green.  This can happen within the bodies of a wide range of organisms (here is a list), ranging in size from dolphins&nbs
