Linking fish biomass and coral reefs structural complexity across the Mariana Archipelago
In 2022, the Ecosystem Sciences Division (ESD) led NCRMP across Guam and the Commonwealth of the Northern Mariana Islands—hereafter referred to as the Mariana Archipelago—adding Structure-from-Motion (SfM) image collection protocols as part of its in-wate...
Nearshore bathymetry gap filling around the Island of Oahu, Hawaii
The NOAA Pacific Islands Fisheries Science Center's Coral Reef Ecosystem Division Mapping Program conducted 13 days of acoustic benthic habitat mapping operations aboard the R/V AHI around the island of Oahu, Hawaii. Survey operations extended from Pearl ...
Comparing Coral Colony Surveys From In-Water Observations and Structure-From-Motion Imagery Shows Low Methodological Bias
As the threats to coral reefs mount, scientists and managers are looking for innovative ways to increase the scope, scale, and efficiency of coral reef monitoring. Monitoring changes in coral communities and demographic features provides key information a...
Linking Watershed Activities to Reef Health in American Samoa: Land-Based Sources of Pollution Impacts on Aua Coral Reefs
"The overarching goals of this project were to establish a water quality and biological baseline for reefs in Aua, American Samoa, and provide managers with recommendations on how to reduce land-based sources of pollution (LBSP) in order to protect their ...
Comparing Coral Demographic Surveys From In Situ Observations and Structure-From-Motion Photogrammetry on High Diversity Reefs Shows Low Methodological Bias but Highlights Persistent Areas of Concern
The Pacific Islands Fisheries Science Center’s Ecosystem Sciences Division (ESD) executes the National Coral Reef Monitoring Program (NCRMP) across 40 primary islands, atolls, and shallow banks in the U.S. Pacific. The goal of NCRMP is to understand how r...
Processing coral reef imagery using Structure-from-Motion photogrammetry : Standard operating procedures (2023 update)
The Pacific Islands Fisheries Science Center (PIFSC) has been testing, improving, and streamlining its Structure-from-Motion (SfM) processing pipeline to produce permanent digital records of coral reefs across the U.S. Pacific Islands and Territories. Thi...
Sampling grids to support the collection and analysis of survey data for the National Coral Reef Monitoring Program in American Samoa, Pacific Remote Islands Areas, Main Hawaiian Islands
The sampling grids are identified as essential components for the stratified random sampling design of the National Coral Reef Monitoring Program (NCRMP). The benthic habitat map layers including bathymetry, hard and soft substrates, reef zones and sector...
Comparing coral demographic surveys from in situ observations and Structure-from-Motion imagery shows low methodological bias
NOAA’s Ecosystem Sciences Division (ESD) at the Pacific Islands Fisheries Science Center (PIFSC) executes the NOAA Coral Reef Conservation Program’s National Coral Reef Monitoring Program (NCRMP) across 40 primary islands, atolls, and shallow banks in the...
Managing marine disease emergencies in an era of rapid change
Infectious marine diseases can decimate populations and are increasing among some taxa due to global change and our increasing reliance on marine environments. Marine diseases become emergencies when significant ecological, economic or social impacts occu...
