    • Reef fish Stationary Point Count (SPC) survey data collected by the Guam Long-term Coral Reef Monitoring Program from 2010-08-04 to 2019-12-19 (NCEI Accession 0244405)

    Metadata Updated: March 17, 2023

    The data in this package include fish abundance, length, biomass, and presence/absence data collected as part of the Guam Long-term Coral Reef Monitoring Program (GLTMP). The monitoring team uses a Stationary Point Count Method, adapted from Ault et al. (2006) and NOAA Fisheries, Coral Reef Ecosystem Division (Williams et al., 2011), to conduct the reef fish surveys.

    IMPORTANT NOTE: Changes have been made to the fish SPC survey methodology since its first deployment in 2010. These changes, which are documented in the Data Quality and Lineage sections of the NOAA InPort metadata record (link below) must be considered in order to properly analyze these data. Also, please note that the results of a 2020 analysis of the fish SPC data conducted by Dr. Peter Houk of the University of Guam Marine Laboratory indicated that data collected in 2010 and 2011 by one observer, and data collected by another observer at single site in 2015, did not meet quality assurance standards. In response to the results of this analysis observations recorded by these two observers were not included in the dataset submitted to NCEI. However, these data can be made available upon request. More information regarding Dr. Houk's analysis can be found in the Data Quality section of the InPort metadata record.

    These data were collected using a split-panel sampling approach, whereby a mix of permanent and non-permanent sampling stations (one sampling station = one transect) are visited within each site. The monitoring sites represent high priority reef areas selected by an advisory body comprised of reef managers, researchers, and technicians. The sites were not selected randomly from around the island and thus should not be considered representative of reef condition at the island-scale. While the general location of the sites were selected based on management priority, the site boundaries were delineated using bathymetry and benthic habitat data within ArcGIS; the locations of the sampling stations were generated randomly within each site’s boundaries using ArcGIS.
