©2020 Biological and Chemical Oceanography Data Management Office.Visual survey of substrate types along transects 10 m x 5 contiguous segments. Substrates were classified along the transects at 50 cm intervals from the nearshore reefs in Guam during 2014.
At each of 15 sites, a 50m transect was laid out along the depth contour. Ten-meter segments were processed, equating to five 10m transects per site. The beginning and end points of transects were marked underwater and the transects were revisited three times within one year.
The benthic composition was assessed using the Point Intercept Method, whereby the substrate immediately below the transect line was identified every 0.5m along five 10m transects. Standard categories of benthic composition included both living and abiotic components.
