A unifying theory explaining different power budget formulations used in modern scientific echosounders for fish abundance estimation
(Fisken og Havet;7-2014, Research report, 2014-12-31)Acoustic methods used in fish abundance estimation constitute a key part of the analytic assessment that makes the basis for fisheries research and international regulations of marine resources. The methods rely on ... -

Absorption term in time-varied-gain functions
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1981)A potential source of error in acoustic measurements of fish density is the absorption part of time-varied-gain functions. This should be determined from the 1977 Fisher and Simmons equation. Use of its predecessor, the ... -
