Hardy Inlet was surveyed by underwater drop camera observations in December 2018 and January 2020. Seagrass species distribution and cover (as percentage cover in categories: 0, 1-10%, 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, 1-10%, 10-25%, 25-50%, 50-75%, 75-90%, 90-100%) were recorded. At approximately a third of the sites, physical water profiles and secchi depth were recorded.
The datasets making up the Hardy Inlet Seagrass Survey data are:
