The data in this dataset represent animal sightings and vessel tracks that occurred during nearshore and mid-shelf baleen whale surveys off the coast of Virginia Beach, VA in the VACAPES OPAREA beginning in November 2020. This project is ongoing and data will be updated annually. Work is being performed by HDR under contract to Naval Facilities Engineering Systems Command as part of the U.S. Navy’s Marine Species Monitoring Program sponsored by U.S. Fleet Forces Command.
Sightings and effort data were entered and organized in this geodatabase by HDR. Source data was provided by HDR under the MSM IDIQ contract. Sighting locations represent actual animal locations. Sightings and effort data for this project were collected using a prototype collection application. Because this application used a different database structure, there are no environmentals associated with the effort tracks.
Survey tracklines (aggregated over time) are available online and included in a downloadable zip file (shapefile format).
This section explains attributes included in the original dataset.
OBIS-SEAMAP restricts the attributes available to the public to date/time, lat/lon and species names/counts only.
Should you need other attributes described here, you are encouraged to contact the data provider.
Attributes described below represent those in the original dataset provided by the provider.
All attributes are included in the downloadable file (CSV or ESRI File Geodatabase) for "Complete Set of Dataset".
