Title: Chesapeake Bay CMECS Substrate Component Geodatabase
Short Name: Chesapeake Bay CMECS Substrate
Status: On Going
Abstract:

The CMECS Component Geodatabase houses component layers for the entire Chesapeake Bay. Available component layers currently include the Substrate Component. Future component additions will include Biotic and Geoform.

Purpose:

The purpose of the CMECS Component Geodatabase is to provide a comprehensive set of habitat data for the Chesapeake Bay. The Chesapeake Dataset is built from remotely sensed and in situ measurements of habitat data.

Technical Environment

Description:

ESRI ArcGIS versions between 2011 and the present have been used to delineate polygon boundaries from acoustic survey spatial data products and sediment samples from local and national databases.

Data Quality

Quality Control Procedures Employed:

The integration of existing datasets are considered as is. New polygon data is validated with grab samples. The data should be considered accurate for the time in which it was collected and the inherent limitation of the data collection methods should be considered.

Data Management

Have Resources for Management of these Data Been Identified?: No
Approximate Percentage of Budget for these Data Devoted to Data Management: Unknown
Do these Data Comply with the Data Access Directive?: No
Is Access to the Data Limited Based on an Approved Waiver?: No
If Distributor (Data Hosting Service) is Needed, Please Indicate: Currently hosted by parent office
Approximate Delay Between Data Collection and Dissemination: 1 year
Actual or Planned Long-Term Data Archive Location: To Be Determined
If To Be Determined, Unable to Archive, or No Archiving Intended, Explain:

This is a data synthesis product currently hosted on our parent office FTP. The long term viability of this host is uncertain.

Approximate Delay Between Data Collection and Archiving: 6 month
How Will the Data Be Protected from Accidental or Malicious Modification or Deletion Prior to Receipt by the Archive?:

Redundant backups.

Lineage

Lineage Statement:

Benthic data were aggregated from multiple sources to create a baywide record of seabed material in the Chesapeake Bay. Habitat polygons are classified with the Coastal and Marine Ecological Classification Standard (CMECS) Substrate Component (SC). Source data were collected during the interval 1842-2015. Because of potential temporal changes in bottom conditions and deficiencies in survey methodology, benthic habitat characterizations may be in error in some areas. These are, however, the best data currently available. This is a dynamic dataset. As new surveys occur the resulting CMECS habitat units will be updated.
