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. The datasets making up the seagrass survey data are: Wilson_Seagrass - point dataset Wilson_Seagrass_Extent - polygon showing presence/absence derived from points Wilson_Seagrass_Cover - polygon showing percentage cover derived from points Layers: Wilson_Seagrass_Dec_2017 Wilson_Seagrass where Year = '2017' Wilson_Seagrass_Apr_2018 Wilson_Seagrass where Year = '2018' Wilson_Seagrass_Dec_2019 Wilson_Seagrass where Year = '2019' Wilson_Seagrass_Dec_2020 Wilson_Seagrass where Year = '2020' Wilson_Seagrass_Dec_2021 Wilson_Seagrass where Year = '2021' Wilson_Seagrass_Dec_2022 Wilson_Seagrass where Year = '2022'
