National Coral Reef Monitoring Program: Stratified random surveys (StRS) of reef fish, including benthic estimate data across the main Hawaiian Islands from 2019-04-21 to 2019-10-31 (NCEI Accession 0210958)

browse graphicPreview graphic
The reef fish and benthic estimate data provided in this data set are from stationary point count (SPC) surveys of reef fish conducted by the NOAA Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (ESD, formerly the Coral Reef Ecosystem Division) from April 21 to October 31 during the ESD-led NOAA National Coral Reef Monitoring Program (NCRMP) mission around the main Hawaiian Islands in 2019.

The SPC method catalogs the diversity (species richness), abundance (numeric density) and biomass (fish mass per unit area) of diurnally active reef fish assemblages in shallow-water (less than 30 m) hard-bottom habitats. Visual estimates of benthic cover and topographic complexity are also recorded, with benthic organisms grouped into broad functional categories (e.g., 'Hard Coral', 'Macroalgae'). A stratified random sampling (StRS) design is employed to survey the coral reef ecosystems throughout the main Hawaiian Islands. The survey domain encompasses the majority of the mapped area of reef and hard bottom habitats and the stratification includes island, reef zone, and depth. Sampling effort is allocated based on strata area.

Purpose 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 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.

Processing Steps
  • Parameter or Variable: REEF AND/OR BOTTOM REGIME - PERCENT COVER (measured); Units: percent; Observation Category: in situ; Sampling Instrument: swimmer/diver; Sampling and Analyzing Method: On completing the fish count, divers make rapid visual estimates of benthic cover and structural complexity of the substrate within their survey cylinder. Benthic cover is estimated for broad functional groups (e.g., hard coral, sand, macroalgae). Structural complexity is determined by estimating the amount of the cylinder within 5 substrate-height bins (<20 cm, 20-50 cm; 50-100 cm; 100-150 cm, and >150 cm).; Data Quality Method: Visual estimates of benthic cover are useful as broad indication of the reef benthic assemblages present at each survey site, but there is considerable scope for error in rapid diver estimates of this kind..
  • Parameter or Variable: MACROINVERTEBRATE CENSUS (measured); Units: unitless; Observation Category: in situ; Sampling Instrument: swimmer/diver; Sampling and Analyzing Method: Urchin and boring urchin categorized as dominant (D), abundant (A), common (C), occasional (O), or rare (R).
  • Parameter or Variable: FISH CENSUS (measured); Units: count; Observation Category: in situ; Sampling Instrument: swimmer/diver; Sampling and Analyzing Method: For the current NOAA Fisheries Ecosystem Sciences Division stationary point count (SPC) method, pairs of divers record the number, size, and species of all fishes observed within visually estimated cylinders 15 meters (m) in diameter. At the start of a survey dive, a pair of divers first lay down a 30-m transect line along a predetermined depth contour, and then the two divers move to the 7.5- and 22.5-m marks on that line; these marks serve as the centers of two adjacent SPC cylinders. During the first 5 minutes of a survey, the divers create a list of the fish species observed in or passing through their cylinder. After the first 5 minutes, divers systematically proceed down their species lists, counting and estimating the size (total length, or TL) of each fish present to the nearest centimeter. Species seen after the 5 minutes or outside of the survey area are recorded as present. Only shallow water (0 to 30 meter depth range) hard-bottom habitats are surveyed. The survey sites were randomly selected using a systematic process based on available habitat and bathymetric data. Although efforts are made to include broad spatial coverage of surveys at each island, weather conditions and other environmental constraints may have prevented the team from surveying exposed reef areas.; Data Quality Method: The same methods of data collection are used at each surveyed site. Observations at each site were made by divers who have been trained, and met minimum standards in identifying species present at the survey locations and in estimating size of fishes in survey counts. However, all species identifications are made visually, sometimes in situations where a fish is only briefly seen. Observations, including species identification and sizing, are periodically checked during expeditions for consistency between divers (diver bias) or other discrepancies. Data entry is usually conducted on the same day as the surveys using a data entry interface with several data controls employed, and are quality controlled by the divers using a two-person system. Following a mission, the data is then run through rigorous quality control checks by the data management team before the data are migrated to the Oracle database. Given the size of the data set, there remains some possibility of typographical or other errors..
