- Abstract:
-
BPI Structures are derived from a focal mean analysis on bathymetry and slope.
The bathymetry grid (5 m cell size) is derived from bathymetry from three 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, and
lidar, both collected by Naval Oceanographic Office; and bathymetry derived from multispectral
IKONOS satellite imagery. BPI Structures was created using the Benthic Terrain Modeler
(http://www.csc.noaa.gov/products/btm/). Cell values represent one of 13 classes in an index
of seafloor terrains.This data set is for Tinian and Aguijan Islands, and Tatsumi Bank,
Commonwealth of the Northern Marianas (CNMI).
- Purpose:
-
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 R/V AHI
(Acoustic Habitat Investigator), a 25' survey launch owned and
operated by the NOAA Pacific Islands Fisheries Science Center in
Honolulu, HI. These data are integrated with bathymetry derived
from multispectral IKONOS satellite data and multibeam and lidar
bathymetry data provided by the US Naval Oceanographic Office.
The metadata for the bathymetry is documented in the product metadata,
TinMBLiDBmos_metadata.txt.

Bathymetric Position Index Structures were derived from the gridded bathymetry (TinMBLiDBmos)
using the Benthic Terrain Modeler (BTM). The BTM (written for ArcGIS 8.x or 9.x) may be downloaded from
http://dusk2.geo.orst.edu/djl/samoa/tools.html.
BPI Structures are derived from two scales of a focal mean analysis
on bathymetry and slope. After testing various experimental combinations, two scales
(50 and 250) best identified fine scale structures while minimizing noise and optimizing
possible reef structures (also after Lundblad et al. 2006; see Supplemental_Information). Three
ranges of slope define flat, slope, and near vertical: x < 5; 5 < x < 70; x > 70.
There may be edge effects at the outer extent of the data.
