Title: Seafloor substrate (hard and soft bottom) maps at select islands and atolls in American Samoa, the Mariana Archipelago, and the Pacific Remote Island Areas
Short Name: Hard Soft Substrate: ESA
Status: Completed
Creation Date: 2016-08
Revision Date: 2018-04
Publication Date: 2018
Abstract:

Seafloor substrate (i.e., hard vs. soft bottom) maps from 0 to up to 50 m depths around select islands and atolls in American Samoa, the Mariana Archipelago, and the Pacific Remote Island Areas were produced by the NOAA Fisheries Ecosystem Sciences Division (ESD). The islands and atolls include Tutuila, Ofu and Olosega, Tau, and Rose in American Samoa; Anatahan, Maug, Aguijan, Pagan, Rota, Tinian, Saipan, and Guam in the Mariana Archipelago; and Howland, Jarvis, Kingman, Palmyra, and Johnston in the Pacific Remote Island Areas. This is a preliminary product, derived from integrating two existing map products: hard and soft seafloor substrate maps derived from an unsupervised classification of multibeam backscatter and bathymetry derivatives produced by ESD, and shallow-water benthic habitat maps generated by the NOAA Centers for Coastal Ocean Science. The resulting maps were then updated with ESD's groundtruth data, including biological survey data and benthic cover data derived from the analysis of seafloor images. The final maps were interpolated to fill in gaps and smoothed to remove isolated pixels, and the substrate data were constrained up to 50-m depths. For the Pacific Remote Island Areas where no benthic habitat maps were available, hard and soft substrate maps were newly generated from high spatial resolution satellite images.

Purpose:

Seamless hard and soft seafloor maps were initially requested by the NOAA Fisheries Pacific Islands Regional Office (PIRO) Protected Resources Division to assist with management of 15 coral species that occur in the Indo-Pacific and are listed as threatened under the Endangered Species Act. Some of these coral species are known to be found in American Samoa, the Mariana Archipelago, and the Pacific Remote Island Areas. The effort was funded by the NOAA Coral Reef Conservation Program.

Supplemental Information:

The substrate maps were produced for Tutuila in American Samoa, and Saipan and Guam in the Mariana Archipelago (PIRO's Tier 1 priorities for management of ESA-listed corals) in the first year of the project (2016). Substrate maps for the 6 islands in American Samoa and the Pacific Remote Island Areas (PIRO's Tier 2 priorities) were completed in the second year (2017). Substrate maps for PIRO's Tier 3 priorities in the Mariana Archipelago (Maug and Anatahan), American Samoa (Rose), and the Pacific Remote Island Areas (Howland, Jarvis, Kingman, Palmyra, and Johnston) were completed in the last year of the project (2018).

NOAA Coral Reef Ecosystem Program (CREP) Data Sharing Recommendations, version 9.0 updated August 12, 2015:

CREP welcomes the opportunity to collaborate on research issues contributing to the scientific basis for better management of marine ecosystems. CREP has a very diverse set of field activities that generates large volumes of data using an array of data collection protocols.

The following recommendations are for your consideration as you use this data:

1) Data analyses should take all field exigencies into account. The most effective way to do this would be active collaboration with CREP principal investigators.

2) 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.

3) If you collect or generate data for the same study areas, CREP requests that you share relevant information on complimentary data collections.

4) 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.

Description:

An example hard- and soft-bottom substrate map of Tutuila (prepared using a different methodology compared with the substrate maps prepared for the project described here).

Technical Environment

Description:

Arc ASCII files created using ArcGIS 10.3, 10.4.1 and 10.5.1 in a Microsoft Windows environment.

Data Quality

Representativeness:

Tier 1 and Tier 2 method: Two primary maps describing the benthic habitats were used in the analysis. ESD hard-soft substrate maps were derived from unsupervised classification of multibeam backscatter and bathymetry derivatives. The Biogeography Program shallow-water benthic habitat maps are derived from IKONOS satellite imagery (Quickbird satellite imagery for Palmyra Atoll). Ground truthing data include ESD's biological survey locations (both fish and coral), and the benthic images acquired during Towed Optical Assessment Device (TOAD) surveys.

Primary method for Tier 3: the predictive substrate maps were produced from recently acquired WorldView satellite images.

Accuracy:

Refer to the metadata and documentation for the accuracy of each dataset included in the analysis (go to Sources in the the Lineage section).

For hard and soft substrate maps newly developed from WorldView 2 satellite imagery, the classification results were compared against ESD's biological survey locations (both fish and coral surveys), with 95-99.5% agreement.

Analytical Accuracy:

As of yet, these data have not been compared with external references or other published data.

Completeness Report:

Improved hard and soft bottom seafloor substrate maps were prepared for approximately 28 locations grouped into three priority tiers, and the maps have been submitted to the Pacific Islands Regional Office, Protected Resources Division for their review to support management of corals listed under the Endangered Species Act. These maps may be subject to updates as new data and information become available. The following locations were priorities for PIRO, however substrate maps could not be prepared for Supply Reef or the offshore banks of Guam due to the lack of available data. Also, due to limited availability of bathymetry for Anatahan and Aguijan, the substrate maps for these areas were not constrained to the desired depth limit (20 m for both locations).

Conceptual Consistency:

Data are collected for resource management and research purposes and are tested for internal consistency. Each GeoTiff file was derived following the method described in the lineage section.

Quality Control Procedures Employed:

Tier 1 and Tier 2 method: The accuracy of the two existing map products used in the analysis---1) hard and soft seafloor substrate maps derived from an unsupervised classification of multibeam backscatter and bathymetry derivatives produced by ESD, and 2) shallow-water benthic habitat maps generated by NOAA National Centers for Coastal Ocean Science Biogeography Program---were assessed with ESD's in-situ surveys and benthic data derived from the analysis of seafloor images. Once all data were integrated, the products were visually inspected by ESD's researchers.

Primary Tier 3 method: the method was developed initially for an area in West Hawaii where multiple sources of accurate, reliable data were available. Applying the method to islands in the Pacific Remote Island Areas, the process and resulting classifications were quality controlled by a group of team members before the products were finalized.

Lineage

Lineage Statement:

The steps in this analysis included: 1) re-categorizing all data to simple hard/soft substrates, 2) integrating all data following data prioritization rules established by an accuracy assessment, 3) filling gaps in data using interpolation, and 4) extracting the data to known depth ranges for the coral species in question.

Biogeography Program shallow-water benthic habitat maps and ESD backscatter-derived hard-soft substrate maps were unavailable for several locations in the Pacific Remote Island Areas. Satellite images were processed for these places using the method described in Mumby and Edwards (2000) and then unsupervised classification was applied to derive hard and soft substrates for these places.

Methodology for demographic surveys of adult and juvenile corals

Process Steps

Process Step 1

CC ID: 345085
Description:

First, the accuracy of two primary maps for three islands - Tutuila in American Samoa, Guam and Saipan in Mariana Archipelago were examined using the ground truthing data. Due to a wide area of overlap between the two datasets, it was necessary to make a decision on how to treat the two datasets in these areas. As the two datasets were produced from different methods, and from different underlying data (multibeam bathymetry versus satellite imagery) there were naturally discrepancies between the two datasets. Examination of the ground truthing data showed that the Biogeography Program shallow-water benthic habitat map provided better representations of overall classifications for all three islands. For both maps, the sand classes produced poor accuracy. This might be due to the disparity of the data acquisition time among the datasets, and the sand cover might be greatly shifted over time. Based on the accuracy assessments and uncertainties, a pragmatic decision was taken to integrate all the datasets following data prioritization rules:

1. Hard classes from ground truthing data

2. Biogeography Program shallow-water benthic habitat map

3. ESD backscatter-derived hard-soft substrate map

These data prioritization rules are applied to the rest of the islands. ESD backscatter-derived hard-soft substrate maps are only available for Tutuila, Ofu/Olosega and Tau islands, and Rose Atoll in American Samoa; and Guam, Saipan, Tinian, and Pagan islands in Mariana Archipelago. For Rota, Aguijan, Maug, and Anatahan islands in Mariana Archipelago and Palmyra Atoll in Pacific Remote Islands, only the Biogeography Program shallow-water benthic habitat map and available ground truthing data were used. The pixel resolution is dependent on the available datasets: if ESD hard-soft substrate maps are available, the pixel resolution of the products inherits the resolution of the ESD hard-soft substrate maps. Otherwise it will inherit the resolution of the Biogeography Program shallow-water benthic habitat map.

Process Step 2

CC ID: 345086
Description:

For the Biogeography Program shallow-water benthic habitat map, polygons were first deleted that were not required for this product; the polygons where the Major Reef Structure (M_STRUCT) was either 'Unknown' or 'Other Delineations' were deleted, leaving only polygons where M_STRUCT was 'Coral Reef and Hardbottom' or 'Unconsolidated Sediment.' The polygon shapefile was then converted into an ArcGIS Raster, using the ArcGIS tool, 'Polygon To Raster’. The raster values were checked to ensure that the same value was equivalent to hard substrate as in the ESD backscatter-derived hard-soft map, where 'Coral Reef and Hardbottom' was classed as 'hard' and 'Unconsolidated Sediment' was classed as 'soft'.

Process Step 4

CC ID: 345091
Description:

To combine the two maps and ground truthing data, all layers were mosaiced, using the ArcGIS tool, 'Mosaic To New Raster.' Based on the data prioritization rules, the two maps were first mosaiced using the 'FIRST' method of the ArcToolbox Tool 'Mosaic to new raster' where the Biogeography Program shallow-water benthic habitat map was the 'first' raster in the mosaic. This meant that where there was overlap between the two datasets, the Biogeography Program shallow-water benthic habitat map was used, and the ESD backscatter-derived hard-soft substrate map was used to fill in gaps. Then, the ground truthing data were mosaiced with the combined map using the the ‘FIRST’ method where the ground truthing data was the ‘first’ raster in the mosaic to update the combined map. However, even using this method, artifacts in the data remain. It should also be borne in mind that the sand areas may be problematic for both primary maps; The Biogeography Program shallow water benthic habitat map may misrepresent high reflective hard substrate areas as sand, whereas the ESD backscatter-derived hard-soft map may under-represent soft sediment at the surface, particularly if there is rocky substrate underlying the soft sediment.

Process Step 5

CC ID: 345090
Description:

For ground-truthing data, to estimate the survey areas, 30-m radius buffers were generated around the locations of the reef fish surveys* and coral demographic surveys and 15-m radius buffers for the image locations of hard classes from the TOAD. All polygons were assigned as ‘hard’. Similar to the Biogeography Program shallow-water benthic habitat map, the buffer polygons were then converted into an ArcGIS Raster.

*Locations of reef fish surveys are included as ground-truth data because NOAA ESD only surveys hard bottom coral reef habitats as part of its standard operating procedures to conduct reef fish surveys.

Process Step 6

CC ID: 345092
Description:

Gaps were filled with interpolation in ArcGIS environment. ‘Focal statistics’ was used in ‘Raster Calculator’ tool to calculate majority value within three by three cell neighborhood for each cell location where there is no value. ‘Majority filter’ was then applied to remove isolated single pixels.

Process Step 7

CC ID: 751854
Description:

Neither the Biogeography Program shallow-water benthic habitat nor the ESD backscatter-derived hard-soft substrate maps were available for Howland and Jarvis islands, Johnston Atoll and Kingman Reef in the Pacific Remote Island Areas. WorldView-2 images were processed for these places using the method described in Mumby and Edwards (2000). Then, unsupervised classification was applied in ArcGIS desktop to derive Hard and Soft substrate maps.

Process Step 8

CC ID: 345094
Description:

Both interpolated and non-interpolated Integrated hard-soft maps and the satellite-derived substrate maps were extracted using the known depth contours for ESA species using 'Extract by Mask' tool in ArcGIS.
