Lineage
| Lineage Statement: |
Acoustic data were recorded at the five split-beam frequencies using Simrad EK80 software. Acoustic measurements were collected from 16 m below the sea surface to within 0.5 m of the sounder-detected bottom or a maximum of 1,000 m in deep water. Data were analyzed using Myriax Echoview post-processing software. See National Marine Fisheries Service (NMFS) 2013.

| Instrument / Gear: | Instrument |
| Instrument Type: | echosounder |
| Description: |
The Simrad EK80 is the most modern "high end" split beam scientific echo sounder in the fishery scientific market. Based on more than 60 years of research and development in close collaboration with leading marine scientists this wide band echo sounder system has succeeded the famous EK60, which became an international standard for fish stock assessment. The Simrad EK80 can operate a large number of frequencies simultaneously ranging from 10 to 500 kHz. A wide selection of high quality accurate transducers is available. |
