Abstract:

These data were collected to examine larval Atlantic Bumper abundance and condition in relation to the Deepwater Horizon oil spill (DWHOS). Ichthyoplankton samples were collected monthly (May through August) along a cross-shelf transect off the coast of Alabama (USA) prior, during and after the DWHOS. Samples were collected during daylight hours using a Bedford Institute of Oceanography Net Environmental Sampling System (BIONESS; Open Seas Instrumentation, Inc.). The BIONESS had a 0.25-m2 mouth opening fitted with 333 um or 202 um mesh nets. All Atlantic Bumper larvae used in the morphometric analyses were imaged under a dissecting microscope fitted with a high-resolution digital camera (Canon EOS Rebel T3i, Canon, Inc.). Body dimensions were measured using -Solution Lite imaging software (IMT i-Solution, Inc.).

Purpose:

These data were used to examine potential impacts of the Deepwater Horizon oil spill on larval Atlantic Bumper (Chloroscombrus chrysurus) abundance and body condition.
