Micronekton sampling gear Intercalibration Experiment Survey #1 (MIE-1) (SE0413L2, EK60)
The goal of the cruise was to collect micronekton samples using three different type of midwater trawl: Cobb trawl, Isaacs Kidd Midwater Trawl (IKMT), and a Hokkaido University Frame Trawl (HUFT). Trawls were conducted off the lee coast of the Island of Oahu, Hawaii, in approximately 1,000 m deep waters. Acoustic backscatter was simultaneously monitored during trawls using an EK60 system operating at 38 and 120 kHz frequencies. Trawls sampled the nighttime shallow scattering layer and daytime deep and shallow scattering layers. It total, 18 Cobb, 19 IKMT, and 20 HUFT were completed.

| Distribution Formats |
- Kongsberg/Simrad instrument files (.raw or .wcd) (Version: 1)
- File Specification: Kongsberg/Simrad .raw files are generated by ME70, EK60 or ES60 instruments. They contain power and optionally angular position data with each beam/frequency identified by an independent channel. See the Simrad interface specification manual for further information. The .wcd files are generated by Kongsberg EM302 or EM122 instruments. See Kongsberg documentation for more information.
