Skildring:Echogram of station 364 (38 kHz) with depth profile and predictions of blue whiting (blue), herring (red), mackerel (green), and mesopelagic fishes (orange). Images at top are from the positions indicated along the trawl’s path and show the bounding boxes calculated by the object detection model. The size of the bubbles in the centre panel are proportional to the number of fish predicted per minute. The stacked histogram at bottom similarly shows the number of each fish species per minute but av

Skildring:Broadband echogram showing backscattering by a small natural seep of methane (red box) near Node 7 of the Lofoten Vesterålen Ocean Observatory. The broadband frequency response of the seep is also shown (lower right inset). The seep consists of a few small single bubbles rising from the seafloor at a depth of 220 meters, clearly observed in the broadband data.

Skildring:The target strength of individual fish depends on swimbladder inflation. Measured target strength from salmon in a net pen before, during and after the surface was closed with a netting roof. Lack of access to the surface deprived the fish from access to air for filling their swimbladders. Measurements in three different net pens showed the same trend (one colour for each net pen).
