Abstract

Understanding the spatial distribution, intensity, overlap, and cumulative impact of human activities and environmental stressors is essential for effective management and protection of ecosystem services generated by coral reefs. The data described here are that of the GIS layers of the eco-geospatial tool developed by staff of the Ecosystem Sciences Division (ESD) at the Pacific Island Fisheries Science Center (PIFSC) for American Samoa Coral Reef Drivers, hosted by Pacific Islands Ocean Observing System (PACIOOS) at http://www.pacioos.hawaii.edu/projects/coral-drivers-amsam/. Partners included the American Samoa Division of Marine and Wildlife Resources and the American Samoa Coral Reef Advisory Group.

This eco-geospatial tool gathers, organizes, analyzes, models and visualizes spatially-explicit information for American Samoa. Hereby, GIS layers are developed to provide the spatial patterns of anthropogenic and environmental drivers that influence the status of coral reefs in the region and the potential for degradation, including satellite-based oceanography (sea surface temperature [SST], chlorophyll-a, photosynthetically active radiation [PAR], Turbidity [Kd490]), wave power, coastal habitat modification, and sediment export to nearshore.

These geospatial products provide the basis to answer questions such as which places and habitat types are the most impacted; which stressors should be the greatest concern in different areas; and where to prioritize different management strategies. In addition, these datasets also inform watershed management and conservation action plans.

Title: Eco-spatial data layers of coral reef ecosystem drivers in American Samoa
Short Name: American Samoa: eco-geospatial tool
Status: Completed
Publication Date: 2021-10
Abstract:

Understanding the spatial distribution, intensity, overlap, and cumulative impact of human activities and environmental stressors is essential for effective management and protection of ecosystem services generated by coral reefs. The data described here are that of the GIS layers of the eco-geospatial tool developed by staff of the Ecosystem Sciences Division (ESD) at the Pacific Island Fisheries Science Center (PIFSC) for American Samoa Coral Reef Drivers, hosted by Pacific Islands Ocean Observing System (PACIOOS) at http://www.pacioos.hawaii.edu/projects/coral-drivers-amsam/. Partners included the American Samoa Division of Marine and Wildlife Resources and the American Samoa Coral Reef Advisory Group.

This eco-geospatial tool gathers, organizes, analyzes, models and visualizes spatially-explicit information for American Samoa. Hereby, GIS layers are developed to provide the spatial patterns of anthropogenic and environmental drivers that influence the status of coral reefs in the region and the potential for degradation, including satellite-based oceanography (sea surface temperature [SST], chlorophyll-a, photosynthetically active radiation [PAR], Turbidity [Kd490]), wave power, coastal habitat modification, and sediment export to nearshore.

These geospatial products provide the basis to answer questions such as which places and habitat types are the most impacted; which stressors should be the greatest concern in different areas; and where to prioritize different management strategies. In addition, these datasets also inform watershed management and conservation action plans.

Purpose:

American Samoa Coral Reef management agencies are mandated to protect coral reef ecosystems and the people who depend on them. Currently the spatial distribution, intensity, overlap and cumulative impact of human activities and environmental stressors is essential for effective management and protection of ecosystem services generated by coral reefs, is not readily available and easily accessible to resource managers and policy makers. The data layers generated in this project provide the means to identify how environmental and anthropogenic drivers may influence the spatial patterns of coral reef ecosystems across American Samoa, and support management aimed at promoting reef resilience and the protection of ecosystem services. This tool synthesizes large datasets and relevant environmental variables that will help managers in the territory answer these questions and then make informed management decisions for coral reef ecosystems.

Technical Environment

Description:

R , ArcGIS, and sedimentation modeling with the InVEST toolset

Data Quality

Representativeness:

Coastal habitat modification is limited to data collected in 2003, and does not represent reflect recent developments.

Accuracy:

Ocean color products are unreliable (heavily influenced) by the substrate reflectance in the nearshore area, so the nearshore pixels are filtered out (no values). These filtered blank cells were filled in with the estimated values from neighboring pixels.

Limitations of InVest SDR model include that the Universal Soil Loss Equation represents only rill or sheet erosion process, and doesn’t include gully, streambank and mass erosion. The models also average sediment export to the nearshore, doesn’t capture the intense storm events, and the equation was developed for the U.S. mainland

Completeness Report:

GIS layers were developed with data for specific timeframes, as noted in this metadata record.

Conceptual Consistency:

Data for these layers were collected by multiple partners and detailed on the website of which the eco-geospatial tool is hosted. This project is also related to the Ocean Tipping Points project, which was developed for Hawai'i conservation and management. This tool was developed as a series of collaborative meetings among partners.

Quality Control Procedures Employed:

Data collected and produced by models was examined for each data layer as described on http://www.pacioos.hawaii.edu/projects/coral-drivers-amsam/#data

Lineage

Lineage Statement:

To develop the LBSP GIS layers, there are three main components: satellite based oceanography, coastal habitat modification, and sediment export to nearshore. All data collected is publicly available, and utilized in an ArcGIS environment. The InVEST toolset was used to model sedimentation

The number of layers included in the tool which span the three components:

5 layers of chlorophyll, 5 layers of kd490, 5 layers of PAR, 5 layers of SST, 1 layer of wave power,1 layer of sediment, and 1 layer of coastal modification

Process Steps

Process Step 1

CC ID: 1096323
Description:

Satellite-based Oceanography Component:

Part I (with R and ERRDAP): Publically-available data was obtained for the multiple datastreams for satellite-based oceanography. Oceanographic variables: Sea surface temperature (SST) , Chlorophyll-a (CHL), PAR/irradiance (PAR), Turbidity/kd490 (KD4), and Wave power* (WAV). For SST, Chl-a, PAR, Kd490: R was used to take data from ERRDAP to calculate Oceanographic metrics.

Part II (in ArcGIS): After the climatology metrics are calculated, ocean color products (Chl-a, Kd490, PAR) will go through extra steps to remove unreliable nearshore values (due reflectaction) and fill in those gaps by averaging the neighbor values. All products are extracted by a 10km buffer. These processes are done in the ArcGIS environment, and the detailed steps are described in the LBSP project - SOP for processing remote sensing data.docx.

Data sources: SST (blended of multiple sensors): to achieve the longest time series (Operational Sea Surface Temperature and Sea Ice Analysis (OSTIA) Sea Surface Temperature Reanalysis (1985-2002), Geo-Polar Blended Night-only Sea Surface Temperature Reanalysis (2002-2016), Geo-Polar Blended Night-only Sea Surface Temperature Near Real-Time (2017 to present)); PAR data is from Aqua MODIS; Chl-a is from ESA Ocean Color CCI v.3.1 (blend of ESA's MERIS, Aqua MODIS, SeaWiFS LAC and GAC, and VIIRS); Turbidity/kd490 is derived from the same sensor as chl-a: ESA Ocean Color CCI v.3.1 (blend of ESA's MERIS, Aqua MODIS, SeaWiFS LAC and GAC, and VIIRS).

Metrics calculated: Long term mean (MEAN) calculated by taking the average of all weekly data for each pixel, Standard deviation of long term mean (SDEV) calculated by taking the standard deviation over all weekly data for each pixel, Maximum monthly climatological mean (MMCM) calculated by first taking the average of all 8-day periods for each month, then taking the maximum of those 12 values for each pixel. Also Maximum annual average anomaly (MAAA) calculated by taking the average of the annual maximum values in excess of the MMCM for each pixel, and Average annual frequency of anomalies (AAFA) calculated by the average # of weeks where an anomaly occurred divided by number of weeks in a year.

Only long term mean was derived for wave power, which was developed by Jeanette Clark to use Wave Watch III global wave model data and coastline analysis of wave exposure

Process Step 2

CC ID: 1096324
Description:

Coastal habitat modification component:

Coastal Habitat Modification, defined as Area of the alteration, or removal of geomorphic structure as a result of human use, was measured with Benthic Habitat Maps created by NOAA National Center for Coastal Ocean Science Biogeography Branch and the Environmental Sensitivity Index created by NOAA Office of Response and Restoration. Data were collected in 2004, extends to ~3 km offshore, identifies habitat areas such as sand, hardbottom reef, scattered rock, artificial/dredged. To develop a coastal habitat modification model, two input layers are mosaiced with a 250m raster file; In summary, this layer combines man-made shoreline modifications and in-water modifications to coastal habitat, and includes a buffer to indicate possible adjacent affected areas. Data for shoreline modification is from 2003, does not show recent development.

Process Step 3

CC ID: 1096325
Description:

Sediment export to nearshore component:

The annual amount of sediment (tons/yr) reaching the coast was calculated using the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) Sediment Delivery Ratio model for Tutuila. Sediment load is a function of land use and vegetation type, geology, soil characteristics, rainfall, slope, and hydrology. Only land areas that drain to a stream which reaches the coast and have a sediment supply were considered.

InVest Sediment Delivery Ratio

Available for download at: https://naturalcapitalproject.stanford.edu/software/invest

Documentation: http://data.naturalcapitalproject.org/nightly-build/invest-users-guide/html/sdr.html#

Rainfall, digital elevation models, soil, land cover, and watershed data was input into the InVest SDR model to estimate annual soil loss and amount of sediment exported to the stream.

Digital Elevation Model (DEM) data is from LiDAR, collected in 2012 and downloaded from NOS Data Access Viewer(https://coast.noaa.gov/dataviewer/#/)

Projection: UTM 2S

Horizontal Datum: WGS84/ITRF

Vertical Datum: NAVD88

Output Resolution: 1.0m

Not all drainage networks are captured in DEM and need to be manually adjusted

Watershed polygons were created with the DEM in ArcGIS taking into account flow direction, accumulated flow, watershed delineation, and stream network.

Rainfall/ Erosivity map was taken from NRCS Field Office Technical Guide: https://efotg.sc.egov.usda.gov/references/public/HI/R_Factor_Map_Am_Samoa.doc then digitized. Erodibility values were extracted from NRCS Web Soil Survey Website and joined with the polygon shapefile
