Climate stations are 3-4 sites per island that were selected in a stratified random fashion to be roughly equally spaced around the island, along the 15 m contour, on hard bottom, and at least 1 km away from a river mouth or embayment. Once selected we assess multiple features of the coral reef environment including in-situ temperature (STR), seawater carbonate, net carbonate accretion (CAU), bioerosion (BMU), and cryptobiota diversity (ARMS). Structural complexity is known to be an important component in coral reef ecosystems. Ecosystem relationships that correlate with structural complexity include reef fish density and biomass, live and branching coral cover, urchin abundance and algal cover (Graham and Nash 2013). In many cases, the benthic complexity is an important indicator of benthic and fish communities. The data were collected around the Hawaiian archipelago as part of the NOAA Pacific Islands Fisheries Science Center (PIFSC), Coral Reef Ecosystem Program (CREP) led missions in 2013 and 2016. These data can be accessed online via the NOAA National Centers for Environmental Information (NCEI) Ocean Archive. 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 is intended to coordinate 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 will be 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.

This integrated approach will consolidate 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 Coral Reef Ecosystem Program (CREP) 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). Each year, CREP scientists work closely with CRCP and local partners to collect biological data on fish populations and coral reef communities from strategically selected sites during Reef Assessment and Monitoring Program (RAMP) missions. 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. false eng false Data View View: V0_TOPOGRAPHIC_COMPLEXITY 2017-01-23 publication CSV - Comma Separated Values (Text) CSV - Comma Separated Values (Text) Beck, Brian 301-713-4844 1315 East-West Highway Silver Spring MD 20902 brian.beck@noaa.gov distributor https://accession.nodc.noaa.gov/0159150 WWW:LINK-1.0-http--link V0_TOPOGRAPHIC_COMPLEXITY HAWAII 2013.csv Benthic complexity and urchin abundance data captured by the NOAA Coral Reef Ecosystem Program at sites across the Hawaiian archipelago in 2013. download https://accession.nodc.noaa.gov/0157760 WWW:LINK-1.0-http--link V0_TOPOGRAPHIC_COMPLEXITY HAWAII 2016.csv Benthic complexity and urchin abundance data captured by the NOAA Coral Reef Ecosystem Program at sites across the Hawaiian archipelago in 2016. download dataset Accuracy Observations at each site were made by divers who have been trained in the benthic complexity and urchin abundance estimate protocols. Between years there may be some variance in the location of the transect tape due to oceanographic conditions. Visual estimates of abundance are useful as a broad indication of the urchin assemblages present at each survey site, but there is scope for error in diver estimates of this type. Analytical Accuracy The benthic complexity surface relief measurements are binned within 1 of 5 classification categories. NOAA PIFSC CREP’s use of the 5-category method is the same category delineation employed by CREP’s fish team for substrate height and was adapted from the University on North Carolina at Wilmington’s Protocol for Measuring Topographic Complexity. Complexity categories and the measurements are as follows: Category 1: < 0.2 m Category 2: 0.2 – 0.5 m Category 3: 0.5 – 1.0 m Category 4: 1.0 – 1.5 m Category 5: > 1.5 m DACOR (dominant, abundant, common, occasional, rare) abundance codes are used to quantify urchins in the NCRMP plot. The number of “free” urchins and boring urchins within the NCRMP plot is visually estimated. The same category delineation is employed by CREP’s fish team for urchin abundance estimates. DACOR categories are quantified as follows: D - Free Urchins: 101-999; Boring Urchins: 501-999 A - Free Urchins: 51-100; Boring Urchins: 251-500 C - Free Urchins: 21-50; Boring Urchins: 101-250 O - Free Urchins: 6-20; Boring Urchins: 26-100 R - Free Urchins: 0-5; Boring Urchins: 0-25 Completeness Measure The data are complete as entered. Any null values recorded are due to an incomplete field survey and not by omission. Completeness Report The benthic complexity and urchin abundance data are collected at the 15m NCRMP stations. Conceptual Consistency The same methods of data collection are used at each surveyed site. Benthic complexity and urchin abundance survey employed by the NOAA Coral Reef Ecosystem Program (CREP) since 2013. Climate stations are 3-4 sites per island that were selected in a stratified random fashion to be roughly equally spaced around the island, along the 15 m contour, on hard bottom, and at least 1 km away from a river mouth or embayment. Once selected we assess multiple features of the coral reef environment including in-situ temperature (STR), seawater carbonate, net carbonate accretion (CAU), bioerosion (BMU), and cryptobiota diversity (ARMS). At the NCRMP station a 10m transect is run from the reference stake parallel to shore and in roughly a cardinal (N, S, E, or W) direction. At the 10m mark of the transect tape, a second 5m transect is deployed perpendicular and down-slope. This gives a total of a 15m transect and forms 2 of the boundary sides of the NCRMP plot. Bearings of each transect are recorded. Along the 15m transect tape, record two max vertical relief measurements per meter (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). The frequency # should add up to 30 units for a 15m transect. Maximum depth, minimum depth, and maximum vertical relief are also recorded. These measurements are defined as: Maximum depth - deepest point in the NCRMP plot Minimum depth - shallowest point in the NCRMP plot Maximum vertical relief - height of tallest reef structure present within the NCRMP plot Urchin abundance is estimated by conducting a visual census of free and boring urchins within the NCRMP plot and is recorded using DACOR (dominant, abundant, common, occasional, rare) abundance codes.
