National Coral Reef Monitoring Program: Benthic Complexity and Urchin Abundance at Climate Stations in the Pacific Remote Island Areas from 2014 to 2018

Metadata Updated: November 10, 2023

Benthic complexity and urchin abundance data were collected as part of NOAA's ongoing National Coral Reef Monitoring Program (NCRMP). These data were gathered around the Pacific Remote Island Areas as a part of the NOAA Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (formerly the Coral Reef Ecosystem Division) led missions from 2014 to 2018.

During these missions, the variables of benthic complexity and urchin abundance were recorded by SCUBA divers during visual surveys at NCRMP climate stations. A select number of climate sites were chosen per island in hard-bottom habitat at 15-m depths in a stratified random fashion.

To record benthic complexity, the divers ran a 15-m transect from the reference stake for the site and estimated two maximum vertical relief measurements per meter along the 15-m transect (based on an area of 0.5 m x 1 m to the left and 0.5 m x 1 m to the right of each meter on the transect) for a total of 30 measurements. The measurements were tallied into five substrate height bins, including 0-20 cm, 20-50 cm, 50-100 cm, 100-150 cm, and >150 cm. The total frequency for the five substrate height bins is 30 units for a 15-m transect. Maximum depth, minimum depth, and maximum vertical relief were also recorded for the climate station.

Free and boring urchin abundance was estimated within the climate station and recorded using DACOR, an abundance code based on visual estimation; dominant (D), abundant (A), common (C), occasional (O), and rare (R).

Lineage Benthic complexity (i.e., substrate height) and urchin abundance survey method employed by the PIFSC Ecosystem Sciences Division (ESD) since 2013. ESD's use of the 5-category method for benthic complexity was adapted from the University on North Carolina at Wilmington’s Protocol for Measuring Topographic Complexity. The category delineations for benthic complexity and urchin abundance are the same as those employed by ESD's fish team.
