NEFSC Small Pelagics Acoustic/Midwater Trawl Survey (DE0302, 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.

Lineage Statement | The data files contain the echogram "Q" and single target detections "E" telegrams for 18 (T1), 38 (T2), and 120 (T3) kHz data. The sample angle "B", power "W", volume backscatter "V", and TS "P" data for the 38 kHz were collected, and are available upon request from the NEFSC. |
