Benthic Surveys in Faga'alu, American Samoa: benthic cover derived from line-point intercept (LPI) surveys in August 2012

Description

The data described here were collected in Faga'alu, American Samoa in August 2012 via line-point intercept (LPI) surveys by the NOAA Coral Reef Ecosystem Program (CREP). At each survey site, a SCUBA diver quantitatively documented the benthic composition at 20-cm intervals along two 25-m transects for a total of 125 data points per transect. All living benthic elements (e.g., coral, algae, and other sessile invertebrates) were identified to the lowest taxonomic level possible. Raw survey data consist of counts of benthic elements, including but not limited to coral, carbonate pavement, sand, rubble, macroalgae, crustose coralline algae, turf algae, as well as other sessile invertebrates along the two transects. The data allows for the assessment and monitoring of community structure and composition, and provide the basis for computing quantitative estimates of benthic cover (%) at higher taxonomic levels like functional group (coral, macroalgae, turf algae) or on a finer taxonomic resolution such as genus level.

These data can be accessed online via the NOAA National Centers for Environmental Information (NCEI) Ocean Archive. Additionally, coral demographic surveys were conducted in 2013 and 2015 and coral surveys in 2012, photoquadrat benthic images were collected in 2012 and 2015, and the 2015 images were analyzed for benthic cover composition (all documented and archived separately).
