Recent environmental change and atmospheric contamination on Svalbard as recorded in lake sediments – synthesis and general conclusions
(Peer reviewed; Journal article, 2004)The major patterns of biostratigraphical and geochemical change detected in a multidisciplinary study on recent environmental change and atmospheric contamination on Svalbard are summarised and synthesized. The patterns ... -
Evaluation of harvest control rules: simple one-parameter versus complex multi-parameter strategies
(Master thesis, 2004)Harvest control rules (HCR) are sets of well-defined rules that can be used for determining annual fish catch quotas or effort. If a management policy can be expressed as a HCR, then the HCR provides means to determine the ... -
Effects of seismic shooting on the lesser sandeel (Ammodytes marinus Raitt) - a field study with grab sampling and in situ video observations
(Master thesis, 2004)Seismic shooting with airguns has been conducted continuously in the North Sea for about 40 years. In the past two decades there has been conflicts of interest between Norwegian industrial trawlers fishing for sandeel and ... -
The seasonal cycle in the Atlantic transport to the Barents Sea during the years 1997–2001
(Peer reviewed; Journal article, 2004)The seasonal cycle in the Atlantic inflow to the Barents Sea is investigated by using 4-year long records from moored current meters, additional moorings of shorter duration, and hydrographic measurements. A higher transport ... -
Recent environmental change and atmospheric contamination on Svalbard as recorded in lake sediments – an introduction
(Peer reviewed; Journal article, 2004)This paper outlines an interdisciplinary project on recent environmental change and atmospheric contamination on the high Arctic archipelago of Svalbard (76º30'N – 80º30'N). It describes the rationale and aims of the project ... -
The intercept is a poor estimate of a calibrated radiocarbon age
(Peer reviewed; Journal article, 2004)Intercept-based methods of generating a point estimate of a calibrated radiocarbon date are very popular, but exhibit undesirable behaviour. They are highly sensitive to the mean of the radiocarbon date and to adjustments ... -
Palaeolimnological and sedimentary responses to Holocene forest retreat in the Scandes Mountains, west-central Sweden
(Peer reviewed; Journal article, 2004)A suite of analyses was performed on sediments accumulated during the last 10 700 years in Lake Spaime, a small, hydrologically open water body in the modem alpine tundra zone of the Scandes Mountains, west-central Sweden. ... -
The rise and fall of forests

Lake-sediment evidence for local and remote sources of atmospherically deposited pollutants on Svalbard
(Peer reviewed; Journal article, 2004)Twenty-one lakes along the west coast of Svalbard were cored between 28 July and 14 August 1995. Five cores were 210Pb dated and analysed for spheroidal carbonaceous particles (SCPs), indicators of deposition from fossil-fuel ... -
Functional Sites in Proteins: analysis and annotation of five nuclear functional sites for the ELM resource
(Master thesis, 2004)Proteins are molecular tools which a cell expresses from specific genes, where the protein has one or several functions. An example of a protein function can be to detect a particular hormone, transporting itself to the ... -
The Norwegian Atlantic Current in the Lofoten basin inferred from hydrological and tracer data (129I) and its interaction with the Norwegian Coastal Current
(Peer reviewed; Journal article, 2004-01-14)From three hydrological sections taken across the Lofoten Basin in May 2000, we estimated geostrophic transports of 7.2 Sv (Sverdrup = 106 m³ s-¹) for the Norwegian Atlantic Current (NAC) and its division between northern ... -
Sub-populations of coastal cod with different behaviour and life-history strategies
(Peer reviewed; Journal article, 2004-02-19)This study provides evidence of countergradient variations in life-history traits among coastal cod Gadus morhua off the Norwegian coast, suggesting the existence of sub-populations. One-yr-old wild-caught individuals from ... -
Velocity field of the western entrance to the Barents Sea
(Peer reviewed; Journal article, 2004-03-13)By the use of 4-year long records from moored current meters between 71°30′N and 73°30′N of the western entrance to the Barents Sea, the velocity field of the Atlantic inflow is examined. The mean velocity field shows the ... -
The planetary biology of cytochrome P450 aromatases
(Peer reviewed; Journal article, 2004-08-17)Background: Joining a model for the molecular evolution of a protein family to the paleontological and geological records (geobiology), and then to the chemical structures of substrates, products, and protein folds, is ... -
Genomic Insights into Methanotrophy: The Complete Genome Sequence of Methylococcus capsulatus (Bath)
(Peer reviewed; Journal article, 2004-09-21)Methanotrophs are ubiquitous bacteria that can use the greenhouse gas methane as a sole carbon and energy source for growth, thus playing major roles in global carbon cycles, and in particular, substantially reducing ... -
Ballan wrasse (Labrus bergylta) predation on hatchery reared scallop (Pecten maximus) spat
(Master thesis, 2005)Sea ranching of the great scallop (Pecten maximus) may have a high potential for future aquaculture in Norway. The edible crab (Cancer pagurus) and starfish (Asterias rubens) have been identified as the major predators, ... -
Differences in soil arthropod communities along a high altitude gradient at Shergyla Mountain, Tibet, China
(Peer reviewed; Journal article, 2005)This is the first time that the soil arthropod communitycomposition along a high-altitude gradient (3,837, 4,105, and5,050 m a.s.l.) has been investigated in eastern Tibet, China.Five soil samples of 50 cm super(2) were ... -
Evaluation of potential reference genes in real-time RT-PCR studies of Atlantic salmon
(Peer reviewed; Journal article, 2005)Background: Salmonid fishes are among the most widely studied model fish species but reports on systematic evaluation of reference genes in qRT-PCR studies is lacking. Results: The stability of six potential reference genes ... -
