Raw EK80 echosounder data of polar cod collected by wideband autonomous transceiver in mesocosm AZKABAN 2023-01-19 and 24

Broadband active acoustic measurements using two echosounders (90-170 kHz and 185-255 kHz) of polar cod (Boreogadus saida) collected in Billefjorden in a mesocosm (2m x 2m x 8m). The experiment was completed from the wharf in Ny-Ålesund. The fileset includes measurements from the experiments of January 19 and 24, 2023 and includes CTD data.
