EK500 Water Column Sonar Data Collected During DE0101
NEFSC Small Pelagics Acoustic/Midwater Trawl Survey (DE0101, 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. |
