Guins, M., Rees, D, and A. Lay2023Prepared for U.S. Fleet Forces Command, Norfolk, Virginia Please contact data providerObjectives for this study are 1) to improve the understanding of local and seasonal haul-out patterns, and the numbers of seals hauled out during daylight hours; 2) to investigate any haul-out patterns in relation to environmental factors; and 3) to investigate differences between vessel-based surveys and time-lapse camera data collection. The data and results of these efforts will further improve the assessment of potential impacts from the Navy including training and testing activities, installation construction (e.g. pile driving) and vessel-transiting activities as required under the Marine Mammal Protection Act and National Environmental Policy Act for Commander, U.S. Fleet Forces Command (USFF) and Commander, Navy Installations Command in the region. These data may also provide important baseline information for the assessment of potential future impacts from climate change or other anthropogenic activities.The sightings were made from trail cameras.2019110420220513ground conditionIn workAs neededVirginia-76.07587-75.841437.1882337.03731 NoneMarine Animal SurveyMarine BiologyMarine mammalsVisual SightingLand-basedNoneVirginiaAtlanticTaxon coveredMarine mammalsIntegrated Taxonomic Information SystemUnknownNot applicableDownloaded April, 2004http://www.itis.usda.gov/Refer to the contact information of the datasetRefer to the contact information of the datasetmailing and physical address
