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 ... -
Abundance and production of lanternfish (Myctophidae) in the western and northern Arabian Sea
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1981)The mesopelagic fauna of the western and northern Arabian Sea between Mogadisco and the Indo-Pakistanean border was studied on cruises with R.V. "Dr. Fridtjof Nansen" during 1975-1976. A deep scattering layer was observed ... -

Abundance estimates of the spawning stock of blue whiting (Micromesistius poutassou (Risso, 1810)) in the area west of the British Isles in 1972-1974
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1975)An analysis is made on the blue whiting data from the echo surveys conducted during 1972-1974 for assessment of the spawning stock west of the British Isles. Acoustic data are evaluated using a length dependent density ... -

Acoustic abundance estimation of the spawning component of the local herring stock in Lindaaspollene, western Norway
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1983)During 1978-1980 yearly acoustic surveys were carried out in the spawning area of a small herring stock in the semi-enclosed bay area Lindaaspollene, approximately 30 km north of Bergen, using the Simrad EY-M echo sounder ... -
Acoustic investigations of size and distribution of the Barents Sea capelin stock 1972-1997
(Fisken og havet, Research report, 1998)The abundance and geographical distribution of the Barents Sea capelin stock have been monitored using acoustic methods since 1972. Today, 26 years later, it is one of the few stocks, within the ICES area, for which an ... -
Advection schemes for coastal ocean models on unstructured triangular meshes
(Fisken og havet, Research report, 2000)A variety of advection schemes suitable for use on unstructured triangular grids have been investigated for possible use in coastal ocean models based on the results of a literature survey. Idealised test cases were ... -
