Establishment, expansion and regeneration of aspen (Populus tremula) in the T...
In subarctic Sweden, recent decadal colonization and expansion of aspen (Populus tremula L.) were recorded. Over the past 100 years, aspen became c. 16 times more abundant,... -
Tree line shifts and disturbance events for sites studied in the Torneträsk a...
Aim: Models project that climate warming will cause the tree line to move to higher elevations in alpine areas and more northerly latitudes in Arctic environments. We aimed to... -
Sea ice characteristics at Ice Station Belgica sites Brussels, Patria and Fab...
Ice Station Belgica was commenced in late winter 2007 in the Bellingshausen Sea as part of Sea Ice Mass Balance in Antarctica (SIMBA), an IPY 2007 cruise on the research vessel... -
Bottom water properties observed during Nathanial B. Palmer cruises NBP00-08 ...
We report on observations of dense shelf water overflows and Antarctic Bottom Water (AABW) formation along the continental margin of the Adelie and George V Land coast between... -
Radiocarbon age, and sedimentation and accumulation rate of core JM05-G001 ob...
Instrumental monitoring of the climate at high northern latitudes has documented the ongoing warming of the last few decades. Climate modelling has also demonstrated that the... -
Fatty acid content of POM, sediment, foraminifer and peracarid samples obtain...
In order to investigate the diversity of diet composition in macrobenthic peracarid crustaceans from the Antarctic shelf and deep sea, the fatty acid (FA) composition of... -
Epigeal spider occurrence, abundance and diversity in moist acidic and dry he...
For the 2004-2006 growing seasons, we trapped a total of 6980 spiders (5066 adults, 1914 immatures) using pitfall traps at the Arctic Long Term Experimental Research (LTER) site... -
Aircraft and satellite derived arctic BrO profiles of the tropospheric column
We derive tropospheric column BrO during the ARCTAS and ARCPAC field campaigns in spring 2008 using retrievals of total column BrO from the satellite UV nadir sensors OMI and... -
Mean cover and frequencies of vascular plant species during three decades aro...
Plant species distributions are expected to shift and diversity is expected to decline as a result of global climate change, particularly in the Arctic where climate warming is... -
Survey of living conditions of Arctic indigenous peoples
Major findings of the Survey of Living Conditions in the Arctic (SLiCA) are: (1) A combination of traditional activities and cash employment is the prevailing lifestyle of... -
Lesion, and haematologic and serum characteristics of Weddell seals (Leptonyc...
We examined and collected biomedical samples from Weddell seals (Leptonychotes weddellii) during studies of post-breeding-season foraging behaviour of adults and movements of... -
Crustal uplift rates of 4 GPS stations near Jakobshavn Isbrae (2006-2009)
We analyze 2006-2009 data from four continuous Global Positioning System (GPS) receivers located between 5 and 150 km from the glacier Jakobshavn Isbrae, West Greenland. The GPS... -
Mass balances of different sectors in Antarctica in 1996, 2000 and 2006
Large uncertainties remain in the current and future contribution to sea level rise from Antarctica. Climate warming may increase snowfall in the continent's interior, but... -
(Table 1) Antioxidant concentrations in liver of wild sea bird chicks from th...
The efficiency of antioxidant defenses and relationship with body burden of metal and organic contaminants has not been previously investigated in arctic seabirds, neither in... -

The Advanced Land Observation System (ALOS) Phased-Array Synthetic-Aperture Radar (PALSAR) is an L-band frequency (1.27 GHz) radar capable of continental-scale interferometric... -
Plankton abundance and feeding characteristics of Thysanoessa raschii from Go...
Despite being a key zooplankton group, knowledge on krill biology from the Arctic is inadequate. The present study examine the functional biology and evaluate the trophic role... -
Plankton biomass, POC and PON concentrations, and sinking velocities during t...
Phytoplankton and copepod succession was investigated in Disko Bay, western Greenland from February to July 2008. The spring phytoplankton bloom developed immediately after the... -
Absolute and relative abundances of zooplankton taxa in Kongsfjorden during 2002
Seasonal changes in the zooplankton composition of the glacially influenced Kongsfjorden, Svalbard (79°N, 12°E), and its adjacent shelf were studied in 2002. Samples were... -
Fecal pellet and egg production rates of copepod species at varying suspended...
We investigated the effect of suspended sediments on the vital rates of the copepods Calanus finmarchicus, Pseudocalanus sp. and Metridia longa in a Greenland sub-Arctic fjord.... -
(Table 2) Fatty acid profile of blubber from harp seals and hooded seals from...
Sub-Arctic marine ecosystems are some of the most productive ecosystems in the world's oceans. The capacity of herbivorous zooplankton, such as Calanus, to biosynthesize and...
