Wilson Inlet Seagrass Survey - Cover (DWER-114)

Wilson Inlet was surveyed in December 2017, April 2018, December 2019, December 2020, December 2021 and December 2022 by underwater drop camera observations and/or observations through a viewing cone. Seagrass 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 intevals) and epiphytic cover (as low, medium, high) 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.
