Depth Contours for select locations across the U.S. Pacific Islands

Description

These data are depth contours (isobaths) derived at 50 meters for most islands and reefs in the Mariana Archipelago, American Samoa, and the Pacific Remote Island Areas. Contours at 10- or 20-meter depths have also been derived for a subset of the same locations. These contours are derived from bathymetry sources including multibeam data collected by Coral Reef Ecosystem Program (CREP) at the NOAA Pacific Islands Fisheries Science Center (PIFSC) since 2003, NOAA nautical charts, estimated depths derived from satellite images, and other sources of bathymetry collected by various agencies and entities.

how_2m_hardsoft.zip ZIP FTP link to download the zip file that contains a shapefile for the 10-m depth contour shapefile that has been prepared for Howland. A ReadMe text file is provided that includes information about the source data used to derive the contour. The 10 m contour polygon file for Howland was not provided in 2016 as there was a lack of sufficient data available at that time to derive the isobath. Access to additional better quality WorldView imagery for Howland allowed for new estimated depths to be generated, and therefore sufficient depth information is now available to derive the 10-m isobath.
jar_2m_hardsoft.zip ZIP FTP link to download the zip file that contains a shapefile for the 10-m depth contour shapefile that has been prepared for Jarvis. A ReadMe text file is provided that includes information about the source data used to derive the contour. The 10 m contour polygon file for Jarvis was not provided in 2016 as there was a lack of sufficient data available at that time to derive the isobath. Access to additional better quality WorldView imagery for Jarvis allowed for new estimated depths to be generated, and therefore sufficient depth information is now available to derive the 10-m isobath.
CONTOUR_<REGION>_POLY.zip Unknown FTP link to the folder that contains the zip files to be downloaded, one zip file for each region (Marianas, American Samoa, and Pacific Remote Island Areas). Each region zip file contains a 50-m depth contour shapefile for each island/bank/reef/atoll in the region. A ReadMe text file is provided for each region.
2016_contour_poly.zip ZIP FTP link to download the zip file that contains a shapefile for each 10- or 20-meter depth contour shapefile that has been prepared for a subset of the locations in the region (Marianas, American Samoa, Pacific Remote Island Areas). A ReadMe text file is provided for each region that includes information about the source data used to derive the contours.
