Lineage
| » Lineage Statement |
Acoustic data were recorded at the five split-beam frequencies using ER60 software and, as a backup, acoustic telegram data were logged with Myriax EchoLog 500 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.

| Description |
The Simrad EK60 Scientific Sounder system is a new generation fishery researchtool, based on experience from the EK500. The new electronic hardware is combined with up to date PC processing and Windows operation. The EK60 provides facilities for accurate echo sounding, data storage, data analysis and reporting results. The system communication is through Ethernet, which gives flexibility in the location of the EK60 system units and allows easy access to data from other instruments or stations on a vessel network. A post processing software, BI60, is also included in the EK60 system. |
