American Samoa: coral reef monitoring interactive map and information layers primarily from 2010 surveys

Published by Coral Reef Ecosystem Division (CRED), Pacific Islands Fisheries Science Center (PIFSC), National Marine Fisheries Service (NMFS), National Oceanic and Atmospheric Administration (NOAA) | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 27, 2026 | Last Modified: 2011-12-16T00:00:00.000+00:00
This interactive map displays American Samoa data collected by the NOAA Coral Reef Ecosystem Division (CRED) during the Pacific Reef Assessment and Monitoring Program (RAMP) cruises. The information presented is a combination of standard CRED monitoring summary data and more specific layers generated by request from resource managers and scientists in American Samoa. The fish and benthos data were collected either by rapid ecological assessment (REA) surveys conducted during 2010, or by towed-diver surveys conducted during 2008 and 2010. The map is accompanied by the summary data used to generate the data layers (as excel attachments) and is available in the form of an interactive pdf with layers to make it usable by those without GIS access.
