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
Gridded bathymetry at 40m resolution surrounding Howland Island, within the Pacific Remote Island Areas - Central Pacific Ocean. Bottom coverage was achieved in depths between 8 and 3800 meters. The Arc ASCII grids and floating point geotifs include multibeam bathymetry data acquired over multiple surveys by the NOAA Ecosystem Sciences Division (as of April 2015). The data were acquired using the Simrad EM300, EM3002D, and Reson 8101 multibeam sonars, with sonar frequencies of 30, 300, and 240 kHz respectively.
Notes: Only a maximum of 4000 characters will be included.
Notes: Data collection is considered ongoing if a time frame of type "Continuous" exists.
Notes: All time frames from all extent groups are included.
Notes: All geographic areas from all extent groups are included.
(e.g., digital numeric data, imagery, photographs, video, audio, database, tabular data, etc.)
(e.g., satellite, airplane, unmanned aerial system, radar, weather station, moored buoy, research vessel, autonomous underwater vehicle, animal tagging, manual surveys, enforcement activities, numerical model, etc.)

Lineage Statement:
Process to produce bathymetry grid from source multibeam bathymetry data.
Process Steps:
- 2017-09-10 00:00:00 - As multibeam bathymetry data contributing to grid were acquired over multiple surveys/years, there have been different methods employed to process the data. Generally speaking, data acquired prior to 2015 were treated according to protocol #1, whereas data acquired after 2015 were processed using protocol #2. Protocol 1: Multibeam swath files are acquired in the Generic Sensor Format (GSF) and are edited on a swath by swath basis using SAIC's SABER editing software. The edited swath files are then combined into a Pure File Magic (PFM) format in SABER and area based editing is performed. The edited PFM is then exported as X,Y,Z. The resulting X,Y,Z data are then gridded using xyz2grd, a Generic Mapping Tools (GMT) algorithm that converts an ASCII or binary table to a netCDF grid file format. GMT is an open source collection of tools for manipulating geographic data sets. Grid nodes with more than one value are set to the average value and unconstrained nodes are set to NaN. Finally, the netCDF grid is clipped at a depth that minimizes data gaps for the specified grid cell size and then converted to an ArcGIS ASCII file format using LINUX/UNIX commands in combination with GMT. Protocol 2: Multibeam bathymetry data were acquired in Kongsberg *.all format, and imported into SABER editing software as converted *gsf. Within SABER, relevant offset, sound velocity, and tidal corrections are made prior to exporting *gsf files to QPS Quimera for swath editing. Within Quimera *gsf files are combined to form 60m resolution 'Dynamic Surface'. A medium-tension spline filter is applied to the data, and the Dynamic Surface is progressively corrected as final 2D and 3D direct swath edits are made. The final cleaned surface is exported as a floating point geotif, where in ArcGIS it is merged with the pre-existing 60m resolution grid using the 'Mosaic to new Raster' function. This final combined grid is exported as both ArcGIS ASCII grid and a floating point raster grid. Further information about the multibeam data processing is recorded in the cruise metadata.
(describe or provide URL of description):
New data collected in 2015 were evaluated against pre-existing data before the data were deemed usable and appended to the pre-existing grids.
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.
Missing/invalid information:
- 1.7. Data collection method(s)
- 7.2. Name of organization of facility providing data access

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.
