Characteristics and changes of thermokarst lakes in Canada, Russia and Sweden
Peat plateaus are widespread at high northern latitudes and are important soil organic carbon reservoirs. A warming climate can cause either increased ground subsidence... -
Characteristics of acoustic recordings of narwhals (Monodon monoceros) north ...
A total of 1,690 individual narwhal nonecholocation sounds were recorded over 5 h in 2007 and 2009. Each sound was classified as either tonal (FM) or pulsed (amplitude... -
Initial soil properties and biomass after experimental grazing and warming in...
High-latitude ecosystems store large amounts of carbon (C); however, the C storage of these ecosystems is under threat from both climate warming and increased levels of... -
Abundance of tintinnids in waters of the Argentine Shelf and the Drake Passag...
The relationship between the abundance and diversity of tintinnids and the concentration of chlorophyll a (Chl a) was contrasted between neritic and oceanic waters of the SW... -
Ciliate abundance in waters of the Argentine shelf and the Drake Passage, the...
Ciliates from sub-surface waters of the Argentine shelf and the Drake Passage under austral summer and autumn conditions were examined and compared for the first time. In both... -
Concentrations of perfluorinated carboxylic acids (PFCAs) and sulfonic acids ...
Temporal variations in concentrations of perfluorinated carboxylic acids (PFCAs) and sulfonic acids (PFSAs), including perfluorooctane sulfonate (PFOS) and perfluorooctanoate... -
Breeding success and traits of equal and unequal pairs of little penguins (Eu...
According to life-history theory, individuals optimize their decisions in order to maximize their fitness. This raises a conflict between parents, which need to cooperate to... -
Chlorophyll a and carbon fluxes, and characteristics of the water column duri...
Following the extreme low ice year of 2007, primary production and the sinking export of particulate and gel-like organic material, using short-term particle interceptor traps... -
Radiocarbon ages and clay minerals in sediment cores obtained during a 2009 J...
The origin of two acoustic sediment units has been studied based on lithological facies, chronology and benthic stable isotope values as well as on foraminifera and clay mineral... -
Major and minor element concentrations in the livers of polar bears (Ursus ma...
To assess geographic distributions of elements in the Arctic we compared essential and non-essential elements in the livers of polar bears (Ursus maritimus) collected from five... -
Concentrations of PCBs, DDT and thyroid hormones in gray (Halichoerus grypus)...
The high levels of polychlorinated biphenyls (PCBs) and DDT in gray seal (Halichoerus grypus) and ringed seal (Phoca hispida botnica) in the Baltic Sea have been associated with... -
Ages and geochemical and geophysical characteristics of sediment core MD99-22...
A sediment core from the Lofoten Contourite Drift on the continental slope off Northern Norway, proximal to the former Vestfjorden-Trsnadjupet Ice Stream, details the... -
210Pb dates, radiocarbon ages and sedimentation and accumulation rates of sed...
The magnitude of Late Holocene climatic variations are less significant than those that took place during ice ages and deglaciations. However, detailed knowledge about this... -
Narwhal (Monodon monoceros) sightings and population estimates for the Canadi...
Aerial surveys of narwhals (Monodon monoceros) were conducted in the Canadian High Arctic during the month of August from 2002 to 2004. The surveys covered the waters of Barrow... -
Physical properties and alpha-/gamma-HCH concentrations in sea-ice and snow s...
The alpha- and gamma-hexachlorocyclohexanes (HCHs) are being scavenged from the atmosphere by falling snow, with the average total scavenging ratios (WT) of 3.8 x 104 and 9.6 x... -
alpha- and gamma-Hexachlorocyclohexane concentrations in brine, bulk sea-ice,...
We used holes augered partially into first-year sea ice (sumps) to determine a- and g-HCH concentrations in sea-ice brine. The overwintering of the CCGS Amundsen in the Canadian... -
Physical properties and hexachlorocyclohexane concentrations of sea-ice, wate...
We present evidence that both geophysical and thermodynamic conditions in sea ice are important in understanding pathways of accumulation or rejection of hexachlorocyclohexanes... -
Biometry, isotopic composition and diet of Arctic charr (Salvelinus alpinus) ...
Two modal size groups of sexually mature Arctic charr (Salvelinus alpinus) differing in shape and found at different depths in Lake Aigneau in the Canadian sub-Arctic are... -
Toxoplasma gondii seropositive rates of animals living on Svalbard
Samples (blood or tissue fluid) from 594 arctic foxes (Alopex lagopus), 390 Svalbard reindeer (Rangifer tarandus platyrhynchus), 361 sibling voles (Microtus... -
Geodetic and satellite derived ice surface velocities of Vestfonna ice cap
During 2007 we launched a geodetic campaign on the Svalbard ice cap Vestfonna in order to estimate the velocity field of the ice cap. This was done within the frame of the IPY...
