Coral reefs

Reef location

Extent of coral reefs

This map shows the extent of coral reefs around Kosrae. The data layer shown here is a subset of Kosrae base layer derived by Island Research & Education Initiative (iREi) (2019) from Digital Line Graphs (DLGs) of U.S. Geological Survey (USGS) 1:25,000-scale topographic maps (2001). The shoreline was partially updated and the coral reef features were slightly shifted and partially modified based on WorldView-2 satellite imagery from DigitalGlobe (2015-2018) provided by U.S. Department of Agriculture (USDA) – Natural Resources Conservation Service (NRCS).

Reef classification

Reef geomorphology

This map classifies the reefs around Kosrae by their geomorphology. The dataset used here was created by the Millennium Coral Reef Mapping Project by the Institute for Marine Remote Sensing – University of South Florida (IMaRS-USF) and the Institut de Recherche Pour le Développement (IRD) (2005). Island Research & Education Initiative (iREi) (2019) extracted a subset of the original dataset and formatted it for use in this atlas.

Ocean floor

Lagoon circulation

Reef passes

This map shows the locations of principal passes in the barrier reef around Kosrae. This data layer was derived by Island Research & Education Initiative (iREi) (2019) by slightly modifying data from U.S. Geological Survey (USGS) 1:25,000-scale topographic maps (2001). The place names shown on this map are copied from the source and require thorough verification and correction of spellings to conform with Kosraean orthography.

Bathymetry

Bathymetry

This map shows the bathymetry (depth to seafloor) around Kosrae. It was generated by AutoGrid (2019), a web application that creates grids and map images from multibeam bathymetry data. AutoGrid is a program by the National Oceanic and Atmospheric Administration (NOAA), National Centers for Environmental Information (NCEI, formerly NGDC). Island Research & Education Initiative (iREi) (2019) extracted a subset of the original dataset and formatted it for use in this atlas.
