| * » 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. |

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. |

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. |
