Abstract
Survival, density, and abundance of common bottlenose dolphins in Barataria Bay (USA) following the Deepwater Horizon oil spill
Highlights
Estimated survival rates for dolphins in Barataria Bay during the first 3 yr (2011−2013) after the April 2010 Deepwater Horizon (DWH) oil spill were low relative to other BSE common bottlenose dolphin stocks along the southeast US coast that have been studied with similar mark-recapture techniques
An annual survival rate of 0.951 was reported for the Charleston BSE common bottlenose dolphin stock surveyed between 2004 and 2006 (Speakman et al 2010)
credible interval (CI): 0.937−0.996) and was similar to rates reported in previous studies of BSE dolphins (Wells & Scott 1990, Speakman et al 2010)
Summary
By averaging the daily location of the 7.89 ppt salinity contour over multiple years, Hornsby et al (2017) estimated 1167.385 km2 of dolphin habitat in Barataria Bay (grey areas in Fig. 1) apportioned among the strata as follows: Island habitat = 127.379 km2; West habitat = 355.278 km2; and East habitat = 684.728 km2.
