NEFSC Small Pelagics Acoustic/Midwater Trawl Survey (DE0002, EK500)
The small pelagics cruise will map the distribution of small pelagic species such as Atlantic mackerel, Atlantic herring, silver hake, butterfish, and squid, in the mid-Atlantic and Gulf of Maine regions of the northeast US. Acoustic data are the primary data and midwater trawl sites are selected on an ad hoc basis to sample acoustic backscatter attributed to small pelagic species. The primary gear is multifrequency Simrad echosounders, but midwater trawl, CTD, and a host of other scientific sensor data are collected ancillary to the acoustic data.
