Item Identification

Title: Depth Contours for select locations across the U.S. Pacific Islands
Short Name: Depth Contours
Status: Completed
Abstract:

These data are depth contours (isobaths) derived at 50 meters for most islands and reefs in the Mariana Archipelago, American Samoa, and the Pacific Remote Island Areas. Contours at 10- or 20-meter depths have also been derived for a subset of the same locations. These contours are derived from bathymetry sources including multibeam data collected by Coral Reef Ecosystem Program (CREP) at the NOAA Pacific Islands Fisheries Science Center (PIFSC) since 2003, NOAA nautical charts, estimated depths derived from satellite images, and other sources of bathymetry collected by various agencies and entities.

Purpose:

These data were initially requested by the NOAA Pacific Islands Regional Office Protected Resources Division to assist with management of 15 coral species that occur in the Indo-Pacific and are listed threatened under the Endangered Species Act. Some of these coral species are known to be found in American Samoa, the Mariana Archipelago, and the Pacific Remote Island Areas. The effort is funded by the NOAA Coral Reef Conservation Program. These data can also be used for broader purposes including general references for cartographic purposes, base information for characterization of habitats and marine organisms, and as an explanatory variable for analyses.

Data Set Information

Data Set Scope Code: Data Set
Data Set Type: GIS
Maintenance Frequency: None Planned
Data Presentation Form: Map (digital)
Entity Attribute Overview:

For each region (Marianas [Guam and CNMI], American Samoa, and the Pacific Remote Island Areas), a shapefile containing the 50-meter depth contours has been prepared for each of the islands/reefs/banks/atolls in the region. A ReadMe file for each region containing the details for each island/reef/bank/atoll shapefile is included. An additional zip file contains the 10- or 20-m depth contour shapefiles that have been prepared for a subset of the islands, and also includes a ReadMe file for each region. In a few cases, islands have partial contours for the specific depth requested due to the limited availability of bathymetric data for those particular places.

Distribution Liability:

While every effort has been made to ensure that these data are accurate and reliable within the limits of the current state of the art, NOAA cannot assume liability for any damages caused by errors or omissions in the data, nor as a result of the failure of the data to function on a particular system. NOAA makes no warranty, expressed or implied, nor does the fact of distribution constitute such a warranty.

NOAA Coral Reef Ecosystem Program (CREP) Data Sharing Recommendations, version 9.0 updated August 12, 2015:

CREP welcomes the opportunity to collaborate on research issues contributing to the scientific basis for better management of marine ecosystems. CREP has a very diverse set of field activities that generates large volumes of data using an array of data collection protocols.

The following recommendations are for your consideration as you use this data:

1) Data analyses should take all field exigencies into account. The most effective way to do this would be active collaboration with CREP principal investigators.

2) In all presentations, product releases, or publications using data generated by CREP, proper acknowledgement of both CREP and the individuals responsible for data collection is expected. Citing the DOI (if available) is preferred, a non-DOI example is listed below.

3) If you collect or generate data for the same study areas, CREP requests that you share relevant information on complimentary data collections.

4) Those receiving data are strongly urged to inform the CREP Data Management Team of any errors and discrepancies that are discovered during the course of using these data. They are further urged to bring to the attention of the Team all problems and difficulties encountered in using these data. This information is necessary in order to improve the collections and to facilitate more efficient and economical data processing and retrieval. The users are asked to supply copies of any missing data that may be located, and to provide information as to significant subsets and special aggregations of data that are developed in using the material provided.

A ReadMe text file is provided that includes information about the source data used to derive the contour. The 10 m contour polygon file for Howland was not provided in 2016 as there was a lack of sufficient data available at that time to derive the isobath. Access to additional better quality WorldView imagery for Howland allowed for new estimated depths to be generated, and therefore sufficient depth information is now available to derive the 10-m isobath.

Technical Environment

Description:

Contours were generated using tools available in ArcGIS versions 9.3 and 10.1.

Spatial reference information for each shapefile is included in each shapefile's projection (.prj) file that can be read by any text reader. These files are included in the download file.

Data Quality

Representativeness:

Gridded bathymetry compiled from multibeam data collected by NOAA Coral Reef Ecosystem Program (CREP) since 2003 was the main data source used to derive the contours. Multibeam bathymetry gaps were filled by other data sources including pseudobathymetry derived from satellite images, NOAA nautical charts, and other bathymetry sources collected by various agencies to generate a continuous contour at a location.

Accuracy:

The accuracy of the contours inherit the accuracy of source bathymetry. The attribute and positional accuracy of the gridded bathymetry are reported in the corresponding metadata.

Comparability:

The contours were derived using a consistent method between the source bathymetry; however, no effort was made to assure the comparability of the multibeam bathymetry to the other bathymetry sources.

Completeness Measure:

The contours were derived for locations where bathymetry data is available. Remote areas where no depth information is available are not included.

Precision:

Depth contours are derived by linearly connecting the locations of equal depth values. Therefore the precision of the contours is inherited from the precision of the source bathymetry data. The precision of the gridded bathymetry is reported in the corresponding metadata.

Completeness Report:

Derivation of the contours are complete.

Conceptual Consistency:

The contours were derived by a consistent method using Esri's ArcGIS Toolbox.

Quality Control Procedures Employed:

Contours for each location were visually inspected by CREP researchers.

Data Management

Have Resources for Management of these Data Been Identified?: Yes
Approximate Percentage of Budget for these Data Devoted to Data Management: Unknown
Do these Data Comply with the Data Access Directive?: Yes
Is Access to the Data Limited Based on an Approved Waiver?: No
Approximate Delay Between Data Collection and Dissemination: Unknown
Actual or Planned Long-Term Data Archive Location: No Archiving Intended
If To Be Determined, Unable to Archive, or No Archiving Intended, Explain:

The contours are an interim product prepared as part of a funded project and do not meet the overall needs of said project and will therefor be replaced by more relevant products upon completion of the funded project.

Approximate Delay Between Data Collection and Archiving: Unknown
How Will the Data Be Protected from Accidental or Malicious Modification or Deletion Prior to Receipt by the Archive?:

NOAA IRC and NOAA Fisheries ITS resources and assets.

Lineage

Lineage Statement:

All contours were created from source gridded bathymetry using the Contour tool available in Esri’s ArcToolbox. The source bathymetry is listed in a ReadMe.txt file for each region. If the bathymetry is not available online to download, contact the distributor or the point of contact.
