Data Management Plan
DMP Template v2.0.1 (2015-01-01)Please provide the following information, and submit to the NOAA DM Plan Repository.
Reference to Master DM Plan (if applicable)
As stated in Section IV, Requirement 1.3, DM Plans may be hierarchical. If this DM Plan inherits provisions from a higher-level DM Plan already submitted to the Repository, then this more-specific Plan only needs to provide information that differs from what was provided in the Master DM Plan.
1. General Description of Data to be Managed
Benthic habitat maps depict dominant substrate type and biological cover in depths between 0 and ~150 m for two priority sites in the Main Hawaiian Islands; the NOAA Habitat Blueprint West Hawaii Focus Area (WHFA) and the Hawaii Division of Aquatic Resources (DAR) West Maui priority watersheds.
The primary data source for these maps was a 5-m resolution bathymetry synthesis grid, collected from a number of sources and maintained by the University of Hawaii at Manoa (UH) Hawaii Mapping Research Group (HMRG). Geomorphic derivatives of slope, slope of slope, rugosity and curvature were created from the bathymetry grid using the Benthic Terrain Modeler (http://esriurl.com/5754) in ArcGIS.
New optical seafloor imagery was collected by the NOAA Coral Reef Ecosystem Program (CREP) to produce these maps, and seafloor imagery was also provided from a number of partners including the United States Geological Survey (USGS) the Nature Conservancy, NOAA Biogeography group and the Hawaii Institute of Marine Biology. All images were visually analyzed by CREP to classify dominant substrate type and biological cover.
A Principle Component Analysis performed in ArcGIS removed highly correlated information from the suite of geomorphic surfaces derived from the bathymetry synthesis grid. This was followed by an unsupervised classification using the Iso Cluster Classification tool in ArcGIS. The resulting image was examined and manually corrected using the classification data from the analyzed seafloor imagery as validation. The resulting benthic habitat map delineates eight dominant substrates (Complex Reef, Boulder, Rubble, Mixed Substrate, Pavement, Sand, Mud, and Manmade) and six dominant biological cover types (Coral, Coralline Algae, Turf Algae, Macroalgae, Uncolonized and Unclassified) that extend from the shoreline to ~150 m.

5. Data Lineage and Quality
NOAA has issued Information Quality Guidelines for ensuring and maximizing the quality, objectivity, utility, and integrity of information which it disseminates.
(describe or provide URL of description):
The Iso Cluster Unsupervised Classification tool was used to classify the three-band Principle Component Analysis (PCA) image into distinct structure and cover classes. The unsupervised classification produced a delineated image of substrate and cover of the seafloor across the entire West Hawaii and West Maui priority areas.
- Multibeam bathymetry data collected by NOAA CREP was processed and integrated with existing bathymetry datasets maintained by the University of Hawaii, Hawaii Mapping Research Group (HMRG) to produce a high-resolution (5m) bathymetry synthesis for the entire NOAA Habitat Blueprint West Hawaii Focus Area (WHFA). The Main Hawaiian Islands bathymetry synthesis maintained by HMRG was used as is for West Maui. (Citation: Main Hawaiian Islands Multibeam Bathymetry Synthesis)
- The Benthic Terrain Modeler in ArcGIS 10.3 was used to derive a series of surface complexity layers using the bathymetry synthesis. Eight surface complexity layers (mean depth, standard deviation of depth, curvature, plan curvature, profile curvature, slope, slope of slope, and rugosity) were produced for both priority areas. (Citation: Wright, D.J., Pendleton, M., Boulware, J., Walbridge, S., Gerlt, B., Eslinger, D., Sampson, D., and Huntley, E. 2012. ArcGISBenthic Terrain Modeler (BTM), v. 3.0, Environmental Systems Research Institute, NOAA Coastal Services Center, Massachusetts Office of Coastal Zone Management. )
- A Principle Component Analysis (PCA) using ENVI 5.3 software was performed on the bathymetry synthesis and eight complexity surface layers to remove highly correlated data by transforming the image into nine principle components. The first three principle components described 99% of the data variability. The complexity surfaces that contributed the most variance were depth, mean depth and rugosity. These three principle components were retained for use in the benthic classification process.

- To verify the accuracy of the automated delineation, the classified optical validation points were overlaid onto the delineated image to confirm or correct the dominant substrate and biological cover composition of the seafloor at a given location. The delineated polygon classifications were manually corrected or modified if they disagreed with the optical validation points. When optical validation points were absent, the USGS and NOAA Biogeography Branch benthic habitat maps were used as validation. For areas where no validation data existed, the polygon was considered unclassified.
(describe or provide URL of description):
Corrections for tide variation and vessel attitude are applied to the multibeam data and a CTD (Conductivity, Temperature, and Depth instrument) cast is performed regularly during data collection to correct for variance within the water column.
Multibeam data are tested for internal consistency; however, no effort is made to compare these data to external references or to other published data.
Corrections to unsupervised classification were made by comparing to classified imagery.
6. Data Documentation
The EDMC Data Documentation Procedural Directive requires that NOAA data be well documented, specifies the use of ISO 19115 and related standards for documentation of new data, and provides links to resources and tools for metadata creation and validation.

7. Data Access
NAO 212-15 states that access to environmental data may only be restricted when distribution is explicitly limited by law, regulation, policy (such as those applicable to personally identifiable information or protected critical infrastructure information or proprietary trade information) or by security requirements. The EDMC Data Access Procedural Directive contains specific guidance, recommends the use of open-standard, interoperable, non-proprietary web services, provides information about resources and tools to enable data access, and includes a Waiver to be submitted to justify any approach other than full, unrestricted public access.
