Active Acoustic data in the Labrador Sea and Canadian Arctic (2017-2019)
The dataset is composed of raw files (.raw) recorded with a SIMRAD EK60 three-frequency (38, 120, 200 kHz) split-beam echosounder that was operated continuously during the ArcticNet cruise aboard the CCGS Amundsen from 2017 to 2019. To ground-truth the hydroacoustic signal, various sampling techniques were applied throughout the cruise track such as midwater and bottom trawling as well as plankton net deployments.

- Purpose
-
Climate change has resulted in increased abundances of boreal fish species in the Arctic and altered distributions of indigenous species. Changes in fish composition could result in additional fishing opportunities in the Canadian Arctic. However, while the demersal ecosystem components have received increased attention, the distributions and dynamics of the main pelagic forage fish species (key prey of commercially exploited demersal fish) remain unknown. This project addresses critical knowledge gaps in pelagic ecosystems, which facilitate better forecasting of how ongoing climatic changes will affect fisheries productivity. Acoustic-trawl surveys from the CCGS Amundsen were conducted from 2017 - 2019 to establish baseline knowledge on the occurrence and distribution of Arctic and boreal pelagic fish and zooplankton in Northern Labrador and the Eastern Arctic, and to continue the ArcticNet time-series initiated in 2003. This datasets concerns the hull-mounted acoustic data that were collected from the Amundsen.
