The data in this package include macroinvertebrate belt transect survey data collected as part of the Guam Long-term Coral Reef Monitoring Program (GLTMP). The monitoring team counts the number of individuals of commercially and ecologically important macroinvertebrate species within a 4 m x 30 m belt transect (4 x 25 m prior to 2017) at all stations (except at the Western Shoals stations, where 4 m x 15 m belts were used). The longest dimension of Tridacna individuals is also recorded; these measurements are not included in this dataset but can be provided upon request.

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.

Purpose The macroinvertebrate belt transect data are collected as part of the Guam Long-term Coral Reef Monitoring Program, which documents a number of important parameters related to ecosystem health; these parameters are grouped into three categories: water quality, benthic habitat, and associated biological communities. Many of these parameters are indicators of stressors, and significant changes in these parameters will likely raise concern and possibly trigger management actions. Data collected for these indicators provide important information about the resilience of high priority reef areas around Guam. Monitoring these parameters allows resource managers to evaluate the effectiveness of specific management strategies, and inform the development of new management actions.

Processing Steps
  • Parameter or Variable: MACROINVERTEBRATE CENSUS (measured); Units: count; Observation Category: in situ; Sampling Instrument: visual observation; Sampling and Analyzing Method: All commercially and ecologically important macroinvertebrates are counted within a 4 m x 30 m belt (4 m x 25 m prior to 2017, 4 m x 15 m belt at Western Shoals site) centered on the transect tape. The diver carries out the survey by counting macroinvertebrates along one side of the transect tape (a 2 m belt) and returning along the other side (another 2 m belt), being careful not to double count species near the transect tape or which may have moved from one side to the other. A meter-long PVC pipe is used by the diver to ensure that their estimate of belt width is accurate. Macroinvertebrate taxa surveyed include echinoids, holothuroids, large crustaceans (e.g., Dardanus spp.), edible mollusks (Tridacna spp., Charonia tritonis, Trochus/Tectus spp., Lambis spp., Octopus spp.), large Actinarians (e.g., Heteractis spp., Entacmea quadricolor, Stichodactlya spp.) and the large corallimorpharian Amplexidiscus fenestrafer). Tridacna spp. are measured to the nearest centimeter.; Data Quality Method: Observations at each site were made by divers who have been trained and met minimum standards in identifying species present at the survey locations. The same methods of data collection were used at each of the stations surveyed. Species identification and counts were periodically checked for accuracy and consistency between divers, and little discrepancy was noted. It should be noted that small boring urchins, particularly Echinostrephus aciculatus and Echinometra spp., and nocturally-active or highly cryptic taxa may be under-counted using this survey method. Effort is made to avoid inter-observer bias through consistent training of macroinvertebrate surveyors by the Program Coordinator and by reference to an established protocol document. Improvement over time in observers' general level of skill with the survey method, and an evolving understanding of the taxa at the monitoring sites, should be taken into account when comparing data across time; however, minor improvements in skill are not expected to have a significant impact on data quality. Comparisons of data across sites or across years must take into account differences in environmental and biological aspects of each site. Comparisons for a give site across time should consider any changes to the site boundaries over time. Please refer to the full NOAA InPort metadata record to see how the Tumon site boundaries shifted after 2010. All observations entered into the database through the online data entry system are compared against observations recorded on the raw data sheet. Once all database records are verified the quality control process is marked as complete for all observations associated with a given station/sampling period. It should also be noted that the data management system employs hard and soft validation to minimize data entry errors..
