Abstract

The data in this dataset represent sightings that occurred during nearshore humpback whale monitoring beginning in January 2015 through May 2015 off the coast of Virginia Beach, VA. Work was performed under HDR task order CTO 54 (IDIQ contract award N62470-10-D-3011, NAVFAC LANT).

Purpose

N/A

Supplemental information

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).

Attributes

Overview

Attributes described below represent those in the original dataset provided by the provider.
Only minimum required attributes are visible and downlodable online. Other attributes may be obtained upon provider's permission unless otherwise noted below.

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.

depthsoundingDepth as determined in situ via sounding in meters
distsightThe radial distance to the animal
effortstatusIndication of whether the survey team was actively searching with all designated observers focused on searching for marine mammal sighting cues. Options: On= dedicated observation effort with both observers on watch. If line, strip, or point transect - following formal distance sampling protocol regardless of survey mode (e.g. maintaining observation and platform protocols on a connector line). All other survey types - maintaining a consistent level of observation effort ; Off= not observing; If line, strip, or point transect - not following formal distance sampling protocol regardless of survey mode (e.g. platform speed or altitude is not consistent with protocol, incomplete observer effort, etc). All other survey types - no dedicated observation effort. Compormised= only one observer watching, observing through cloud/fog patches, dark, or other conditions that compromise ability to observe consistently
