This project was the first phase of a monitoring program designed to provide quantitative information on the seasonal occurrence, distribution and density of marine mammals in estuarine and coastal waters around the Marine Corps Base Camp Lejeune. The work consisted of three components:
(1) coastal line transect surveys, designed to provide estimates of the density of marine mammals and sea turtles in near-shore ocean waters;
(2) small boat-based photo-identification surveys to document patterns of residency by individual dolphins; and
(3) passive acoustic monitoring of the occurrence and distribution of bottlenose dolphins in the New River.
We conducted eleven shipboard surveys in the near-shore coastal waters of Onslow Bay from August 2010 to November 2011. We conducted photographic surveys for bottlenose dolphins in the New River on 19 days between October 2010 and November 2011. We recorded 54 sightings throughout the Intracoastal Waterway and New River, with some groups seen as far upriver as Morgan Bay.
5-13-2013: One off-effort sighting did not have group-size estimated, so 1 was used to be conservative and noted in the [notes] column.
