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 (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 Tinian and Aguijan Islands, and Tatsumi Bank, 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.

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.

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. 2011-01-31T00:00:00 otherRestrictions Metadata Access Constraints: None otherRestrictions Metadata Use Constraints: None annually This metadata was automatically generated from the FGDC Content Standards for Digital Geospatial Metadata standard (version FGDC-STD-001-1998) using the 2016-01-11 version of the FGDC RSE to ISO 19115-2 transform.
