Water Flow in Seagrass Ecosystems - Hydrodynamic environment of seagrass meadows
Maintenance and Update Frequency: notPlanned Statement: - Profiles through different meadows - Posidonia australis, Posidonia sinuosa, Amphibolis griffithii, and a 50:50 mixed patch of the two Posidonia species were chosen for the study.

An exposed site was located approximately 500 m further offshore, near Bird Island and was not sheltered by the offshore reef system.
