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: Hardy_Seagrass - point dataset Hardy_Seagass_Extent - polygon showing presence/absence derived from points Hardy_Seagrass_Cover - polygon showing percentage cover derived from points Layers: Hardy_Seagrass_Dec_2018 - Hardy_seagrass points where Year = '2018' Hardy_Seagrass_Jan_2020 - Hardy_seagrass points where Year = '2020' Hardy_Seagrass_Extent_2018 - Hardy_Seagrass_Extent where Year = '2018' Hardy_Seagrass_Extent_Jan_2020 - Hardy_Seagrass_Extent where Year = '2020'

Hardy_Seagrass_Cover_2018 - Hardy_Seagrass_Cover where Year = '2018' Hardy_Seagrass_Cover_Jan_2020 - Hardy_Seagrass_Cover where Year = '2020'
