Abundance of minke whales (Balaenoptera acutorostrata) in the Northeast Atlantic: variability in time and space
(Journal article; Peer reviewed, 2004)Regional sighting surveys with two independent observers on each vessel were conducted each year from 1996 to 2001. Northern minke whales (Balaenoptera acutorostrata) are mostly solitary animals and are only available for ... -

Abundance, maturity and growth of the krill species Thysanoessa inermis and T. longicaudata the Barents Sea
(Journal article; Peer reviewed, 1996-12-05)Thysanoessa inermis and T. longicaudata were the dominant krill species observed in the western and central Barents Sea between 1984 and 1992. Both species are typically boreal and subarctic, and were found in very low ... -

Acclimation with lice-infested salmon improves cleaner fish delousing performance
(Peer reviewed; Journal article, 2021)Securing the welfare and maximising the lice removal efficacy of ~60 million cleaner fish used each year on salmonid farms is essential to develop a productive and ethical industry with low salmon lice Lepeophtheirus ... -
Accumulation and toxicity of monoaromatic petroleum hydrocarbons in early life stages of cod and haddock
(Journal article; Peer reviewed, 2019)A multitude of recent studies have documented the detrimental effects of crude oil exposure on early life stages of fish, including larvae and embryos. While polycyclic aromatic hydrocarbons (PAHs), particularly alkyl PAHs, ... -
Accuracy of the Kirchhoff-approximation and Kirchhoff-ray-mode fish swimbladder acoustic scattering models
(Journal article; Peer reviewed, 2013)The acoustic backscatter from pressure release prolate spheroids and a three-dimensional representation of a fish swimbladder (Chilean jack mackerel, Trachurus symmetricus murphyi) was calculated using four target strength ... -
Accuracy of the Kirchhoff-Approximation and Kirchhoff-Ray-Mode Fish Swimbladder Acoustic Scattering Models
(Journal article; Peer reviewed, 2013-05-14)The acoustic backscatter from pressure release prolate spheroids and a three-dimensional representation of a fish swimbladder (Chilean jack mackerel, Trachurus symmetricus murphyi) was calculated using four target strength ... -
Accuracy of VMS data from Norwegian demersal stern trawlers for estimating trawled areas in the Barents Sea
(Journal article; Peer reviewed, 2011-06-08)The accuracy of vessel monitoring system (VMS) data, used to determine fishing activity in the trawl fishery for gadoids in the Barents Sea, was studied by observer notes and Global Positioning System (GPS) data from two ... -
Achieving Reliable Estimates of the Spatial Distribution of Kelp Biomass
(Peer reviewed; Journal article, 2020)Kelp forests are highly productive systems that are important ecologically and commercially as well as in a blue carbon perspective. Given their importance, there is an urgent need to achieve reliable estimates of the ... -
Acidification of the Nordic Seas
(Peer reviewed; Journal article, 2022)Due to low calcium carbonate saturation states, and winter mixing that brings anthropogenic carbon to the deep ocean, the Nordic Seas and their cold-water corals are vulnerable to ocean acidification. Here, we present a ... -

Acoustic classification in multifrequency echosounder data using deep convolutional neural networks
(Peer reviewed; Journal article, 2020)Acoustic target classification is the process of assigning observed acoustic backscattering intensity to an acoustic category. A deep learning strategy for acoustic target classification using a convolutional network is ... -
Acoustic data collected during and between bottom trawl stations: consistency and common trends
(Journal article; Peer reviewed, 2007)Acoustic data are often collected during bottom trawl surveys. Their use can potentially improve the precision and accuracy of fish abundance estimates if acoustic data collected between trawl stations are consistent with ... -

Acoustic detection and quantification of benthic egg beds of the squid Loligo opalescens in Monterey Bay, California
(Journal article; Peer reviewed, 2006)The squid Loligo opalescens is a key species in the nearshore pelagic community of California, supporting the most valuable state marine fishery, yet the stock biomass is unknown. In southern Monterey Bay, extensive beds ... -
Acoustic detection of the Greenland shark (Somniosus microcephalus) using multifrequency split beam echosounder in Svalbard waters
(Peer reviewed; Journal article, 2022)The conservation status of the long-lived Greenland shark (Somniosus microcephalus) is unknown, and methods for non-invasively estimating local or regional abundances are wanted. Using a multifrequency split beam echosounder ... -
Acoustic estimation of size distribution and abundance of zooplankton
(Journal article; Peer reviewed, 1986)A series of investigations were undertaken to observe and describe the sound backscattering process from larger zooplankton (euphausiids). The target strength versus frequency, size, and aspect angle of the organism was ... -
