Benthic cover derived from line-point intercept (LPI) surveys in Faga'alu, American Samoa from 2012-08-14 to 2012-08-16 (NCEI Accession 0169728)

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).

CREP has a very diverse set of field activities that generates large volumes of data using an array of data collection protocols.\n\nThe following recommendations are for your consideration as you use this data:\n\n1) Data analyses should take all field exigencies into account. The most effective way to do this would be active collaboration with CREP principal investigators.\n\n2) In all presentations, product releases, or publications using data generated by CREP, proper acknowledgement of both CREP and the individuals responsible for data collection is expected. Citing the DOI (if available) is preferred, a non-DOI example is listed below.\n\n3) If you collect or generate data for the same study areas, CREP requests that you share relevant information on complimentary data collections.\n\n4) Those receiving data are strongly urged to inform the CREP Data Management Team of any errors and discrepancies that are discovered during the course of using these data. They are further urged to bring to the attention of the Team all problems and difficulties encountered in using these data. This information is necessary in order to improve the collections and to facilitate more efficient and economical data processing and retrieval. The users are asked to supply copies of any missing data that may be located, and to provide information as to significant subsets and special aggregations of data that are developed in using the material provided.\n\nExample citation:\n\n\"This publication makes use of data products provided by the Coral Reef Ecosystem Program (CREP), Pacific Islands Fisheries Science Center (PIFSC), National Marine Fisheries Service (NMFS), National Oceanic and Atmospheric Administration (NOAA), with funding support from the NOAA Coral Reef Conservation Program (CRCP).
