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).

Abstract: |
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). |
Purpose: |
These data are part of a NOAA Coral Reef Conservation Program (CRCP) funded project aimed at establishing baseline data for coral demographics and benthic cover and composition via Rapid Ecological Assessment (REA) surveys conducted by the NOAA Coral Reef Ecosystem Program (CREP) at Faga'alu Bay, Tutuila, American Samoa between 2012 and 2015. In August 2012 Faga’alu watershed in American Samoa was adopted by the U.S. Coral Reef Task Force Watershed Partnership Initiative as a priority site, with the objective to reduce inputs of land-based sources of pollution to nearby coastal areas and coral reefs within the watershed. As a result, the NOAA Coral Reef Conservation Program (CRCP) invested in 1) the collection of baseline data for corals in Faga’alu Bay (REA surveys conducted by NOAA Coral Reef Ecosystem Program [CREP]), and 2) the monitoring of sediment loads in Faga’alu Stream to document pre- and post-mitigation levels of sedimentation in the stream and the receiving waters below. Led by the NOAA Office for Coastal Management, the overall goal of this capacity-building CRCP-funded project is to establish and eventually turn over the long-term monitoring to the local partners in the jurisdiction, thereby meeting the goals of the Watershed Partnership Initiative. |

Supplemental Information: |
An Erosion and Sediment Control Plan was implemented at Samoa Maritime quarry to reduce excess sedimentation from quarry operations, and mitigation actions from the Plan took place in 2014 to install retention basins designed to stem the input of excess sediments into Faga’alu Stream below the quarry. REA surveys conducted by CREP in 2012 and 2013 serve as the pre-mitigation baseline, and surveys conducted in 2015 by CREP and later by the American Samoa Department of Marine and Wildlife Resources serve to document the downstream effects (e.g., changes to the coral community) in Faga’alu Bay from the mitigation efforts to reduce the sediment loads upstream. Concurrent pre- and post-mitigation monitoring of turbidity and sediment load in Faga'alu is managed by San Diego State University via the CRCP-funded project titled, "Capacity Building for On-Island Impact Assessment of Sediment Load Reduction in Faga’alu Watershed, American Samoa". Long-term monitoring of the stream is transitioning to the American Samoa Environmental Protection Agency. A report entitled "Baseline surveys for coral community structure and demographics in Vatia Bay and Faga'alu Bay, American Samoa" was prepared by NOAA Coral Reef Ecosystem Program for the American Samoa Department of Marine and Wildlife Resources. |

Data Quality
Accuracy: |
The benthic cover parameter observations were made by a single diver who is a benthic ecologist. |
---|---|
Completeness Report: |
The survey sites were selected to be representative of the dominant habitats at this reef system. Each LPI data point was entered separately and given a count of 1, preserving the original sequence in which the LPI points were surveyed in the field. |
Conceptual Consistency: |
The same methods of data collection were used at each of the sites surveyed at this location, and were conducted by the same scientist. |
Quality Control Procedures Employed: |
Data entry is conducted using a data entry interface with several data controls employed, and are quality controlled by the observer against the physical data sheets following data entry. The data is then run through rigorous quality control checks by the data management team before the data are migrated from the MS Access data entry system to the Oracle database. Given the size of the data set, there remains some possibility of typographical or other errors. |

Process Steps
Process Step 1
Description: |
Upon arrival at a survey site, divers entered the water and deployed two 25-m transect lines, which were shared with belt transect surveys of corals. The Line-point Intercept (LPI) methodology was implemented to quantitatively document the benthic cover along the transects. The LPI diver determined the benthic composition at 20-cm intervals along the transect line 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, often substituting functional group categories for turf algae and crustose coralline algae when identification in the field was extremely difficult. Raw survey data consist of counts of benthic elements, including but not limited to coral, carbonate pavement, sand, rubble, fleshy 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. |
