This dataset contains location information of marine mammal, sea bird, sea turtle sightings off of Cape Hatteras, North Carolina, in August 2004.
Our objective is to map the distribution of upper-trophic predators with respect to physical and biological gradients across the North Carolina shelf. A team of observers used standardized population sampling techniques, including line-transect and strip-transect methods, to survey the distribution and abundance of marine mammals, birds and turtles. By repeatedly surveying the study area in conjunction with physical and biological measurements from in-situ and remote-sensing platforms, we will quantify how these predators respond to changes in the oceanography of this dynamic region over short time scales (days) and across seasons (summer - winter).

In addition to the sightings data, effort data and environmental data were recorded. This dataset, therefore, should be used with the effort data.
