Macroinvertebrate belt transect survey data collected by the Guam Long-term Coral Reef Monitoring Program from 2010-08-06 to 2019-09-06 (NCEI Accession 0228762)

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.
