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
