| 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. |
