©2020 Biological and Chemical Oceanography Data Management Office.A split-beam scientific echosounder primarily designed for fisheries research. It can operate seven frequencies simultaneously ranging from 18 to 710 kHz. Real time echo integration and target strength analysis in an unlimited number of layers is provided as well as storage of raw data for replay or analysis in one of several post-processing software packages such as Simrad's BI60.
| Dataset Name | PI-Supplied Description | PI-Supplied Name |
|---|---|---|
| Nautical Area Scattering Coefficients (NASC) from an R/V BIP cruise in the Guaymas Basin, Gulf of California in 2013 (Jumbo Squid El Nino Response project) | Acoustic data were collected nearly continuously using Simrad EK60s at 4 frequencies (38, 70, 120, and 200 kHz). Split beam transducers (Simrad model numbers: 38-12, 70-7c, 120-7c, 200-7c) were mounted 1.5 m below the surface on a rigid pole. | Simrad EK-60 echosounder |
| Nautical Area Scattering Coefficients (NASC) from R/V New Horizon cruises NH1106 and NH1006 in the Guaymas Basin in 2010 and 2011 (Jumbo Squid Physiology project) | Acoustic data were collected nearly continuously using Simrad EK60s at 4 frequencies (38, 70, 120, and 200 kHz). Split beam transducers (Simrad model numbers: 38-12, 70-7c, 120-7c, 200-7c) were mounted 1.5 m below the surface on a rigid pole. | Simrad EK-60 echosounder |
