Sampling locations and transects surveyed. Deployment locations of epipelagic net (red circles), bottom trawl (pink circles), simultaneous epipelagic net and pelagic trawl (blue circles), simultaneous epipelagic net and bottom trawl (yellow circles), and locations of seabird sampling (green rectangles). The CCGS Amundsen route (black line), and simultaneous hydroacoustic and seabird sighting transects (teal line) are presented. The order of the completed transects is indicated by 1–8. The background gradient (white–gray scale) represents the mean sea-ice concentration from 9 June to 12 July 2016. Coastal areas with no available ice data are indicated in black. The dashed box shows the domain of Figure 6. DOI: https://doi.org/10.1525/elementa.339.f1
