Princess Royal Harbour was surveyed in January and March 2021. Seagrass species distribution (Posidonia australis, Posidonia sinuousa, Posidonia coriacea, Halophila sp., Ruppia sp., and Amphibolis sp.) and cover (as percentage cover classes: 0, <15%, 15-45%, 45-75%, >75%) was recorded across 263 observations points across the estuary. The type of meadow (continuous or patchy), epiphytic cover on seagrass (as none, very low, low, medium, high or very high), and macroalgae cover (as percentage cover in categories: 0, <15%, 15-45%, 45-75%, >75%) were recorded at each site. At approximately a third of the sites, physical water profiles, secchi depth and photosynthetically active radiation (euphotic depth) were recorded. When observation locations were inaccessible by boat, sites were accessed from kayaks to make observations. The datasets making up the seagrass survey data are: PrincessRoyal_Seagrass - point dataset PrincessRoyal_Seagrass_Extent - polygon showing presence/absence PrincessRoyal_Seagrass_Cover - polygon showing % cover Layers: PrincessRoyal_Seagrass_Jan_2021 - PrincessRoyal_seagrass points where Year = '2021'

PrincessRoyal_Seagrass_Extent_Jan_2021 - PrincessRoyal_seagrass_Extent where Year = '2021'

PrincessRoyal_Seagrass_Cover_Jan_2021 - PrincessRoyal_seagrass_cover points where Year = '2021'
