Acoustic data in the Northwest Passage: 2005-2014

The dataset is composed of raw files recorded with a SIMRAD EK60 three-frequency split-beam echosounder that was operated continuously during the annual ArcticNet (2005-2014) sampling expeditions in the Canadian Arctic aboard the CCGS Amundsen. Three 7° transducers were hull-mounted, two in oil-filled arctic wells protected by a 2.5 cm thick acoustically transparent polycarbonate plate (38 and 120 kHz) and one in a Traveocean piston well in direct contact with water (200 kHz). The acoustic signal was recorded continuously on a PC using ER60 software version 2.0.0. Ping interval was set at 2 or 3 s and the pulse length was set at 1.024 ms.

Purpose

Arctic cod is the most abundant and dominant fish in the Arctic marine food web, transferring the energy from zooplankton to top predators. In the Canadian Arctic, the large biomass of this key species that must exist to support predators' consumption estimates has eluded detection. Sampling difficulties in the harsh environment usually limit studies of Arctic cod to coastal shallow waters during summer and to the immediate under-ice water. The purpose of this study is to estimate Arctic cod's biomass distribution and describe cod behavior from acoustic backscatter data collected in the Northwest Passage.
