Coral Reef Structural Complexity derived from Structure-from-Motion (SfM) imagery collected at Stratified-Random Sites (StRS) at sites across the Main Hawaiian Islands from 2019-04-21 to 2019-08-06 (NCEI Accession 0268310)

The data described here are structural complexity estimates derived from Structure from Motion (SfM) benthic habitat imagery collected during diver transect surveys conducted at stratified random sites (StRS) by the Pacific Islands Fisheries Science Center (PIFSC) Ecosystem Sciences Division (ESD) during the 2019 NOAA National Coral Reef Monitoring Program (NCRMP) mission to the Main Hawaiian Islands (MHI). The SfM imagery was used to generate orthomosaic images using Agisoft Metashape software. Resulting digital elevation models are used with Rstudio to estimate three habitat structural complexity metrics: rugosity, height range, and fractal dimension.

SfM imagery, collected at Stratified-Random Sites (StRS) across the Main Hawaiian Islands from 2019-04-21 to 2019-08-06, was used to extract data including three metrics of habitat structural complexity (rugosity, fractal dimension, and height range). The photographs were processed using Agisoft Metashape software to generate digital elevation models that were analyzed in R studio to extract estimates of rugosity, fractal dimension, and height range. Data was collected for each site within five 4m2 boxes.

Source imagery is described separately, and access procedures will be described on the following page: https://www.fisheries.noaa.gov/inport/item/63095
The scripts used will be published on GitHub and updated in this data package's InPort metadata page: https://www.fisheries.noaa.gov/inport/item/67851

Purpose The National Coral Reef Monitoring Program (NCRMP) details a long-term approach to provide an ecosystem perspective via monitoring climate, fish, benthic, and socioeconomic variables in a consistent and integrated manner. The NCRMP coordinates various Coral Reef Conservation Coral Reef Program (CRCP) biological, physical, and human dimensions activities into a cohesive NOAA-wide effort. Through the implementation of the NCRMP, NOAA is able to clearly and concisely communicate results of national-scale monitoring to national, state, and territorial policy makers, resource managers, and the public on a periodic basis. The purpose of the Structure from Motion (SfM) surveys throughout the Main Hawaiian Islands is to efficiently and effectively collect benthic data. Estimates of habitat structural complexity will expand our understanding of how structure influences coral reef ecosystem structure, function, and services. The NOAA National Coral Reef Monitoring Program (NCRMP) details a long term approach to provide an ecosystem perspective via monitoring climate, fish, benthic, and socioeconomic variables in a consistent and integrated manner. The NCRMP coordinates various NOAA Coral Reef Conservation Program (CRCP) biological, physical, and human dimensions activities into a cohesive NOAA-wide effort. Through the implementation of the NCRMP, NOAA is able to clearly and concisely communicate results of national-scale monitoring to national, state, and territorial policy makers, resource managers, and the public on a periodic basis. NCRMP is a framework for conducting sustained observations of biological, climate, and socioeconomic indicators at 10 priority coral reefs across the U.S. and its territories. This integrated approach consolidates monitoring of coral reefs under a uniform method in the Pacific, Atlantic, Caribbean, and the Gulf of Mexico for the first time. NCRMP is funded by the CRCP and supported by NOAA Fisheries, NOAA National Centers for Coastal Ocean Science (NCCOS), and many other partners. The PIFSC Ecosystem Sciences Division (ESD) at NOAA Fisheries is leading biological monitoring in the U.S. Pacific Islands Region. The biological component of NCRMP in the Pacific provides a triennial ecological characterization at a broad spatial scale of general reef condition for reef fishes, corals and benthic habitat (i.e., fish species composition/density/size, benthic cover, and coral density/size/condition). Innovative analysis techniques are then used to develop products that give fellow scientists, managers, decision makers and the public a better understanding of a region's resources and how they are changing over time.
