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:CRIMAC survey with G.O.Sars, 2022.11.27-2022.12.03. From Tromsø and Kvænangen to Lofoten, Vestrålen and Myre. We test new ideas and methods in using scientific echosounders and sonars to study fish. We study herring in Kvænangen fjord with broadband echosounders pointing downwards and sideways to port and starboard. We test and measure the size of fish directly from echosounder data. We test various aspects of broadband echosounder use on fish aggregations. We travel to Lofoten/Vestrålen to aid
