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 ... -
Analyse av fangst pr. enhet innsats data for vågehval. Sluttrapport til NFFR.
(Working paper, 1991-06)Innledning: Fangst pr. enhet innsats (cpue) data fra den norske vågehvalfangsten har tidligere vært analysert ved Havforskningsinstituttet med henblikk på å få et bilde av utviklingen i den nordøstatlantiske bestanden ... -
Changes in blood testosterone and progesterone concentrations of the North Atlantic minke whale (Balaenoptera acutorostrata) during the feeding season
(Journal article; Peer reviewed, 2004)An opportunity to study seasonal changes of sex hormones in the North Atlantic minke whale (common minke whale, Balaenoptera acutorostrata) arose when we obtained access to fresh postmortem blood samples from 104 females ... -
A comparison of variability and bias when ageing Northeastern Atlantic minke whales (Balaenoptera acutorostrata) by counting growth layer groups in the mandible and bulla tympanica
(ICES CM documents, Working paper, 2001)The age of 43 minke whales (Balaenoptera acutorostrata) was estimated by counting growth layer groups (GLGs) GLGs in 500um thick haemotoxylin stained transverse sections of left and right mandible. The same whales were ... -
Diet and food availability for Northeast Atlantic minke whales Balaenoptera acutorostrata
(ICES CM Documents;1995/N:19, Working paper, 1995)Ecological studies of the Northeast Atlantic minke whale (Balaenoptera acutorostra) were carried out during spring (mainly April-May), summer (June-July) and autumn (AugustSeptember) in 1993 and 1994. Four small-type ... -
Distribution, abundance and trends in abundance of fin and humpback whales in the North Atlantic
(ICES CM documents, Working paper, 2005)The North Atlantic Sightings Surveys (NASS) are a series of international cetacean line transect surveys, including participation from the Faroe Islands, Iceland, Norway and Spain, that have been conducted in 1987, 1989, ... -
Estimating g(0) from single observer data
(Journal article; Peer reviewed, 2010-06)In this paper we estimate g(0), or equivalently the effective strip half-width, using data from a line transect survey which has been operated in double observer mode only a small fraction of the time. By letting the ... -

First record of gooseneck barnacles (Conchoderma auritum) on a minke whale (Balaenoptera acutorostrata)
(ICES CM Documents;1985/N:9, Working paper, 1985)Clusters of a stalked barnacle, readily identified as Conchoderma auritum, were found attached to both damaged and complete baleen plates of a male minke whale caught off the coast of East Greenland on 16 July 1984. No ... -
Genetic population structure of minke whales Balaenoptera acutorostrata from Greenland, the North East Atlantic and the North Sea probably reflects different ecological regions
(Journal article; Peer reviewed, 2003-02-04)A genetic study to determine the population structure of minke whales Balaenoptera acutorostrata in Greenland, the Central and NE Atlantic and the North Sea was carried out on a sample of 306 individuals. Samples were ... -
Hybrids between common and Antarctic minke whales are fertile and can back-cross
(Journal article; Peer reviewed, 2013-04-15)Background: Minke whales are separated into two genetically distinct species: the Antarctic minke whale found in the southern hemisphere, and the common minke whale which is cosmopolitan. The common minke whale is further ... -
