Northern part of the Eurasian continent indicating the dispersal patterns of the Scandinavian, Barents Sea and Kara Sea ice sheets. Lines shows the terminal positions of Barents/Kara Sea ice sheets 90 000 and 55 000 years ago and of the...
Project aims The earth is made of seven large (108 km2), six intermediate (106–107 km2), and more than 20 smaller (105–106 km2) rigid plates known as microplates. These plates move across the surface of the planet and their creation, interaction,...
Photo: Katarina Abrahamsson Objective The main objective was to investigate the distribution and production of volatile halogenated organic compounds (halocarbons) in different habitats in the Arctic during polar sunrise. Special emphasis was put...
Map showing the sections sampled during Arctic Ocean 2002, the tracks of major water flow between the North Atlantic and Arctic and 129I transport paths (arrows) from Sellafield (S) and La Hague (L). Aims and background This project describes the...
The general flow pattern of waters in the Arctic Ocean and the Nordic Seas. The dashed arrows illustrate surface waters, while the solid illustrates intermediate waters. Scientific background The specific aim of the chemical oceano-graphy project...
Aim of the project Despite being the smallest components of the plankton community, viruses and bacteria play a major role in pelagic food chains and in biogeochemical cycles. Aquatic microbiology is a rapidly developing field, thanks to new...
Aim It may be difficult to believe that compounds you can hold as a powder in the palm of your hand can be transported via the air to remote areas. Nevertheless today we find organic contaminants, such as the well known pollutant DDT, in all...
The sections taken on the Arctic Ocean 2002 expedition. The positions of stations shown in Figures 2 to 5 are indicated. East Greenland Current (EGC), West Spitsbergen Current (WSC), Irminger Current (IC). Background The climate of north-western...
“Algal foam” made up by the haptophyte genus Phaeocystis. Cell size 3–6 μm. Photo: Angela Wulff Aims The aims of the suggested project are to study (I) the content of UV-absorbing compounds (mycosporine-like amino acids, MAAs) in phytoplankton...
Since the 1980’s, flights to Dronning Maud Land in East Antarctica have been carried out within the Russian Antarctic programme. However, it was not until the Antarctic summer season 1997/98 that air transportation to Dronning Maud Land...
The AMANDA detector for high energy cosmic neutrinos has been built (1995 – 2000) deep in the glacier at the Amundsen-Scott base at the South Pole, Antarctica. The scientific goals are among others to use the neutrino particles to investigate the...
In northern Russia ice sheets centred on Scandinavia and in the Barents- and Kara Seas fought to occupy the northern rim of the continent during the last ice age, the Weichselian of western Europe or the Valdaian of Russia. Today, the imprint left...
The economy of Greenland is to a large extent dependent upon income from fisheries. About 93% of the national income is based on export of fish products, and of this approximately 68% is coming from export of shrimps. To allow a sustainable...
The earth radiation deficit at high latitudes necessitates a poleward transport of heat in the atmosphere and ocean, in order to keep up the temperature. The oceanic part is evident in the high latitude Arctic Seas where warm Atlantic water enters...
Six logistically and scientifically interlinked research projects were coordinated under the framework of the Biogeochemistry Programme. The Biogeochemistry Programme partners represented many international research institutions and were funded by...
Sea ice albedo is an important factor determining the overall energy balance of the ocean ice-atmosphere interface and the seasonal processes of sea ice growth and decay. Changes in sea ice albedo can affect regional and global climate through the...
About 100 kilometres of seismic data were acquired within a small area at 87°30’N on the Lomonosov Ridge in support of ODP proposal 533 for scientific drilling. Target oriented seismic surveys represent a greater gamble than the...
All current atmospheric models of how the atmosphere will respond to increasing emissions of carbon dioxide from fossil fuel burning predict global warming. The extent to which emissions must be limited will depend critically on how rapidly that...
Wet and dry deposition are the ultimate paths by which trace gases and particles are removed from the atmosphere. Dry deposition is the transport of species, in gaseous or particulate form, from the atmosphere to surfaces without help from...
Knowledge of the glacial history of the Antarctic Peninsula region, including the South Shetland Islands, has become much enhanced of late. Recent years have seen an increasing number of expeditions of various nationalities studying glacial and...
