The Peel-Harvey Estuary was surveyed in March and April 2021 by underwater drop camera observations and/or observations through a viewing cone. Seagrass species distribution and cover (as percentage cover in categories:
0, 0-10%, 10-25%, 25-50%, 50-75%, 75-90%, 90-100%) were recorded. The canopy height (in 10 cm intervals) and epiphytic cover (as low, medium, high) of seagrass was also estimated. Macroalgae distribution and cover (as percentage cover in categories: 0, 0-10%, 10-25%, 25-50%, 50-75%, 75-90%, 90-100%) were recorded. At approximately a third of the sites, physical water profiles, photosynthetically active radiation (euphotic depth) and secchi depth were recorded.
The datasets making up the Peel-Harvey Estuary Seagrass Survey data are:
PeelHarvey_Seagrass - point dataset
PeelHarvey_Seagass_Extent - polygon showing presence/absence derived from points
PeelHarvey_Seagrass_Cover - polygon showing percentage cover derived from points
