  1. Seagrass Seagrass canopy density Product description • Spatial maps of seagrass canopy density • Coverage and changes in seagrass beds Spatial extent and resolution Source: ESA/University of Exeter/ARGANS • Local to regional • Meter scale Benefits • Permanent monitoring of the state and extent of seagrass/seaweeds and any impact caused Lighthouse reef (Belize, Caribbean)

  2. Coral reefs Coral Reef habitat maps Product description • Spatial maps of coral reef habitats • Fore-reef, back-reef, other ecological zones including and high and low coral cover areas Source: ESA/University of Exeter/ARGANS Spatial extent and resolution • Local to regional • Meter scale Benefits • Permanent monitoring of the state and extent of coral reef habitats and any impact caused

  3. Shallow water habitats Shallow water biodiversity hotspots Product description • Biodiversity map of shallow water habitats Source: Harborne et al. (2006) Ecology 87, 2871-2881. Spatial extent and resolution • Local to regional • Meter scale Benefits • Identification and permanent monitoring of hot spots at risk

  4. Water optical properties Shallow water bathymetry Product description • Map of water depth (bathymetry) Spatial extent and resolution Source: Hedley et al. (2009) RSE 113, 2527-2532 • Local to regional • Meter scale Benefits • Characterisation of bathymetry as input for e.g. modelling waste water dispersion

  5. Water optical properties Sea surface temperature maps Product description • Maps of sea surface temperature climatology and anomalies • Elevated temperature is a key stressor for corals, leading to coral bleaching Source: ESA/University of Exeter/ARGANS events, coral mortality and community shifts on reefs Spatial extent and resolution • Regional • Kilometre scale Benefits • Identification of waste water spills caused by processing facility Sea Surface Temperature Standard Deviation

  6. Coastal wave energy exposure Wave exposure Product description • Coastal wave exposure can be calculated from fetch, wind speed and bathymetry, all derived from EO data Source: ESA/University of Exeter/ARGANS Spatial extent and resolution • Local to regional • Meter scale Benefits • Coastal wave exposure to identify target areas for coastal protection Averaged directional Wave exposure J/m³ wind speed
