Leg I was conducted from 23 June to 12 July 2004. Leg II was conducted from 16 July to 4 August 2004. Both legs started and ended in Narragansett, Rhode Island, United States. The study area for both legs was in mid-Atlantic waters from the 100 m depth contour to the Gulf Stream, from Virginia to Cape Cod, Massachusetts, United States.

A secondary objective was to compare the distribution of these species with each other, physical characteristics, such as water depth and temperature, and biological characteristics, such as relative plankton distribution. notPlanned Debi Palka NOAA Northeast Fisheries Science Center Primary contact dpalka@whsun1.wh.whoi.edu NA NA NA Debi Palka owner NA zd_396 2025-07-31T14:14:05-04:00 dataset Palka, D. 2018.
