This polygon layer represents marine habitat in the East Gippsland region mapped from satellite imagery and aerial photography with underwater video ground-truthing. The mapping was funded by Natural Heritage Trust to increase the capacity of natural resource managers to make informed decisions regarding asset identification, risk assessment, and management action targets for nearshore marine habitats in the region.

This layer contains polygons defining the spatial extent, species distribution and density of seagrass meadows within Mallacoota Inlet mapped from 1999 aerial photography and ground-truthing.

We created merged bathymetry surfaces segmented in GeoTiff format by resolution and depth within the Channel Islands National Marine Sanctuary (CINMS) from more than 20 multibeam mapping surveys. These bathymetry data were collected between 1998 and 2022 by National Oceanic and Atmospheric Administration (NOAA), United States Geological Survey (USGS), Monterey Bay Aquarium Research Institute (MBARI) California State University, Monterey Bay (CSUMB) and Ocean Exploration Trust (OET). Bathymetry data collected by institutions outside of NOAA are reference to overlapping NOAA hydrographic surveys using an average depth difference correction. The merged bathymetric surface resolutions varied by depth from 2x2m in <40m, 4x4m in 36 to 80 m, 8x8m in 72 to 160m, 16x16m in 144 to 320m and to 24x24m in >300m. They can be used to create high-resolution, nearly continuous coverage benthic habitat maps within the CINMS.

These metadata describe Coastal and Marine Ecological Classification Standard (CMECS; Federal Geographic Data Committee, 2012) attributed polygons derived from multibeam echosounder acoustic bathymetry and backscatter intensity data, and from underwater video collected offshore of Morro Bay, California from 2016 to 2020. The polygons have CMECS substrate, geoform and biotic component attributes. Most of the data were collected in support of the U.S. Geological Survey (USGS)/Bureau of Ocean Energy Management (BOEM) California Deepwater Investigations and Groundtruthing I (Cal DIG I) project through collaborations with the National Oceanic and Atmospheric Administration (NOAA) and the Monterey Bay Aquarium Research Institute (MBARI).

This polygon layer identifies shoreline types and habitats in the coastal and shallow subtidal region. The polygon extents are defined by a buffer of the coastline. The layer is based on a map created by Natural Resource Systems for the Land Conservation Council as part of its Marine and Coastal Special Investigation. Shoreline classifications and boundaries in the LCC map were further refined through a comparison with other data sources for the coast. Shoreline categories were defined on the basis of the information requirements of oil spill contingency planning and response personnel.
