Gulf of Mexico Marine Mammal Assessment Aerial Surveys - NRDA

Metadata Updated: February 8, 2018

Aerial surveys were conducted during the spring-summer of 2010 and seasonally during 2011-2012 to assess the abundance and spatial distribution of marine mammals and sea turtles within the region impacted by the Deepwater Horizon oil spill. Surveys were conducted in high-winged twin engine aircraft flying at altitudes of 600-750 feet. Visual observations of marine mammals, sea turtles, birds, and other species are recorded including species identifications, counts of animals. Surveys are conducted along line transects oriented perpendicular to the shoreline and follow protocols consistent with analysis using Distance approaches to estimate detection probability and abundance. These data have been used to evaluate the potential impact of the Deepwater Horizon oil spill on protected species.
