Name: Northern Gannet

Display Field: density

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description: These data represent densities of northern gannet across the marine waters off the coast of South Carolina, as surveyed between 2008-2014. U.S. Fish and Wildlife Service surveys were performed in February, March, August, and October and include wintering sea duck surveys (2008-2011), Atlantic Marine Assessment Program for Protected Species (AMAPPS) surveys (2010-2011, 2012|x2|, 2014), and a South Carolina and Georgia Coast survey (2012). Across these ten surveys, northern gannet were counted along transects and grouped into various distances (in nautical miles) from the coast. Bird counts were then aggregated across surveys by month and distance from coast. Densities (birds per square kilometer) were calculated by dividing the total bird count by the total area surveyed for a given month and distance from the coast. Density standard deviations are included to show the variation in density across surveys of a given month and distance from the coast. The number of surveys performed and surveys in which northern gannet were present are also provided.
