Abstract:
BPI Structures are derived from a focal mean analysis on bathymetry and slope.
The bathymetry grid (5 m cell size) is derived from two sources:
Multibeam bathymetry collected by Coral Reef Ecosystem Division aboard NOAA R/V AHI, and
NOAA Ship Hi'ialakai; multibeam bathymetry collected aboard the US Naval Ship Sumner by the Naval Oceanographic
Office, and also lidar, also collected by the Naval Oceanographic Office.
BPI Structures was created using the Benthic Terrain Modeler (
https://coast.noaa.gov/digitalcoast/tools/btm.html).
Cell values represent one of 13 classes in an index of seafloor terrains.
This data set is for Saipan Islands, Commonwealth of the Northern Marianas (CNMI).
The data were derived in support of NOAA Coral Reef Conservation
Program goals. Goal 1 is to map all U.S. Coral Reef Ecosystems.
This data set specifically addresses Objective 1 and 4: to develop
high-resolution benthic maps and to characterize priority deep
water reefs and associated habitats. This derivative of bathymetry
provides a GIS layer that may be used for benthic and essential fish
habitat characterization, and for the study of geologic features.
By combining the dataset with bathymetry, backscatter, other
derivatives, and in situ data, they collectively compose benthic
habitat maps which are designed to be used to understand and predict
moderate depth (~20m - 150m) benthic habitats for different
organisms that inhabit coral reef ecosystems.
Supplemental_Information:
Gridded multibeam data were collected aboard the Hi'ialakai, a 218
United States National Oceanographic and Atmospheric Administration
(NOAA) research ship and aboard the R/V AHI
(Acoustic Habitat Investigator), a 25' survey launch owned and
operated by the NOAA Pacific Islands Fisheries Science Center in
Honolulu. These data are integrated with multibeam and lidar
bathymetry data provided by the US Naval Oceanographic Office.
For the purposes of creating a bathymetry grid (sai_mb_li_db) these bathymetry
data were also combined with bathymetry derived from multispectral IKONOS
satellite data. The metadata for these bathymetry is documented in the product metadata,
Sai_MB_Li_DB_metadata.txt. However, for the purpose of deriving BPI grids, a version of
this data was used that did not include the IKONOS-derived bathymetry, as these data
were found to introduce artifacts into the BPI products.
