Understanding soft sediment ecosystems

Proud to share this new graphic made with world-leading soft sediment scientists at the University of Auckland.

Soft sediments cover 50% of Earth’s surface and quietly power ocean health — producing oxygen, filtering water, recycling nutrients, creating habitats, and locking away carbon and pollutants.

Out of sight, but vital for life.

Marine plants stabilise the seafloor, provide habitats, remove contaminants, and produce half the oxygen we breathe.

Filter feeders like oysters, mussels, clams, and sponges clean the water and create habitats for other species.

Crabs, sea stars, and sea cucumbers recycle decaying debris and balance food webs.

Burrowing animals mix and oxygenate sediments, moving nutrients and creating living spaces.

Microbes recycle nutrients to fertilise marine plant growth, powering life in the ocean.
