From February 2013 through October 2019, members gathered benthic and macroinvertebrate cover in specific areas identified on Guam. During benthic surveys, members identified corals, algae, seagrass, sponges and macroinvertebrates. Identification of macroinvertebrates was collected by members as well through species, including; echinoderms, mollusks, and crustaceans. Data is supported by photos from the sites. Part of a long-term community monitoring program at irregular intervals which documents the state of the reefs in Guam. Capacity is built among members during local reef monitoring efforts.

Each quadrat sampling was taken every meter and a photo of the quadrat was taken.; Data Quality Method: The benthic cover observations were made by members of the Guam Community Coral Reef Monitoring Program. Members have received basic training in benthic monitoring, but are not formally trained scientists. The benthic cover assessment surveys are conducted periodically as conditions permit and may or may not be replicated. The last two entries from 10/5/2019 have not been QA/QC. Parameter or Variable: MACROINVERTEBRATE CENSUS (measured); Units: count; Observation Category: in situ; Sampling Instrument: visual observation; Sampling and Analyzing Method: observations along a transect in certain quadrats out to 25 meters. Macroinvertebrates were located within one meter of the transect.; Data Quality Method: The macroinvertebrate observations were made by members of the Guam Community Coral Reef Monitoring Program. Members have been trained in basic macroinvertebrate monitoring, but are not formally trained scientists. The macroinvertebrate surveys are conducted periodically as conditions permit and may or may not be replicated..
