Acoustic backscatter in the Eurasian Basin. Profiles of acoustic backscatter from six locations in September 2021 (a-f). The various categories of scatterers are coded with colours. ---- show the temperature from the nearest CTD station, while are the depth intervals where the trawls were conducted (Harstad or macroplankton or both). Note that a single strong echo, observed at about 265 m depth at NB1 (Fig. S18) was excluded when plotting this figure.
