- Abstract:
-
Hard and soft seafloor substrate map, derived from integrating two existing map
products: hard and soft substrate maps derived from an unsupervised classification of multibeam
backscatter and bathymetry derivatives, produced by NOAA Pacific Island Fisheries Science
Center Coral Reef Ecosystem Division (CRED), and shallow-water benthic habitat map of American
Samoa, produced by NOAA Center for Coastal Monitoring and Assessment Biogeography Program.

Shallow-water benthic habitat map
http://ccma.nos.noaa.gov/ecosystems/coralreef/us_pac_terr/
This data is for Rose Atoll, Territory of American Samoa, USA.
- Purpose:
-
The hard and soft seafloor map previously produced by NOAA Pacific Islands
Fisheries Science Center Coral Reef Ecosystem Division is being used to improve
sampling techniques for long-term ecosystem monitoring, to guide
future ground-truthing operations and to identify coral-rich and
species specific environments. By combining this initial product with the
shallow-water benthic habitat map produced by NOAA Biogeography Branch,
a more complete hard and soft substrate map is produced, which fills in
many of the gaps in shallow water.
- Supplemental_Information:
-
Two hard and soft substrate maps were produced by NOAA Pacific Islands
Fisheries Science Center Coral Reef Ecosystem Division, one produced from
data collected by the R/V AHI Reson 8101 240 kHz multibeam sonar, and a
second using data collected by the NOAA ship Hi'ialakai Simrad em300
30 kHz multibeam sonar, covering deeper water. In both cases, the hard-
soft substrate maps were derived using backscatter data, bathymetric
variance (at 2 scales) and bathymetric rugosity. Bathymetry and backscatter
data were resampled to 5 m grid cell size prior to the classification for
shallow water product, and to 40 m grid cell size for the deeper water
product. As no seafloor photographs for groundtruthing were available
for Rose Atoll, the classification was unsupervised. However, in locations
such as French Frigate Shoals, NWHI and Tutuila, American Samoa, where
ground truth data were available, the same unsupervised classification method
has been found to be a good predictor of substrate type in similar depth
ranges and seafloor environments.
The shallow-water habitat map produced by NOAA Biogeography Branch was
derived by digitally delineating habitat boundaries from georeferenced
sonar and orthorectified IKONOS satellite imagery in ArcGIS using the
NOAA Habitat Digitizing extension. A first draft map was completed, and
areas identified for ground validation. At each ground validation point
benthic habitat was characterized by drop camera, free diving or surface
observation. A second draft map was produced incorporating the ground
validation data.

The process description to produce the CRED hard-soft substrate map
can be found in the metadata for that product:
Substrate - hard bottom vs. soft bottom - 5 meter grid
ftp://ftp.soest.hawaii.edu/pibhmc/website/data/amsamoa/benthichabitatlayers/Rose_5m_hardsoft.txt
Substrate - hard bottom vs. soft bottom - 40 meter grid
ftp://ftp.soest.hawaii.edu/pibhmc/website/data/amsamoa/benthichabitatlayers/Rose_40m_hardsoft.txt
The process description to produce the Biogeography Program
shallow-water benthic habitat map can be found in the metadata
for that product:
https://products.coastalscience.noaa.gov/collections/benthic/e99us_pac/
To combine the two maps, several steps had to be first taken
with the Biogeography Program shallow-water benthic habitat map.
First polygons were 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.'
Polygons covering the lagoon were also deleted as these were covered by the 5-m
hard bottom vs. soft bottom product.
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
CRED hard-soft map, where 'Coral Reef and Hardbottom' was classed as 'hard'
and 'Unconsolidated Sediment' was classed as 'soft'.
To combine the three maps, the raster layers were
mosaiced, using the ArcGIS tool, 'Mosaic To New Raster.'
