The first of these adaptive radiations ocurred 370 million years ago, when the earliest tetrapods modified their fins into legs and emerged onto dry land. ...

The purpose of the project was to collect multibeam bathymetry and sub-bottom profile information along the western continental shelf of Greenland in order to characterize the ...

The research project combines knowledge of the function of current ecosystems with data from prehistoric DNA in order to generate scientifically supported predictions of how Arctic ecosystems will be ...

The research project explore how legacies of large scale mining operations have influenced communities in the Nordic part of the Arctic. The objective is to investigate under which ...

The expedition was part of the research programme GEOTRACES, an international study of the marine biogeochemical cycles of trace element and their isotopes. The dynamics of trace metal ...

The expedition was carried out by the Norwegian University of Science and Technology (NTNU) in collaboration with the Swedish Polar Research Secretariat. Two similar expeditions was carried out in 2012 and 2013. OATRC 2015 was ...

... important in terms of primary production, sediment biogeochemistry and ecology. In determining the effects of climate change, most studies focused on single-factor or single-species experiments. Hence, there is a general lack of ...

In this research project, the researchers are studying heat transport between sea and glaciers in the Amundsen Sea. The pathways, variability and heat flux of the warm deep water ...

... Christchurch, New Zealand. The research expedition was organised by the German Federal Institute for Geosciences and Natural Resources (BGR) and was a part of the programme German Antarctic North Victoria Land Expedition (GANOVEX). 23 ...

During the 2002/03 season, the drilling at Dome C reached a depth of 3,200 meters. The preliminary dating shows that the ice is about 900,000 years old at this ...

... up with the Canadian icebreaker Louis S. St-Laurent and launch the expedition. For six weeks, the vessels will operate in the Arctic Ocean, mainly in the Amundsen Basin and in areas around the underwater mountain ranges Lomonosov Ridge ...

In this research project the researchers is studying the ecological drivers behind aquatic tetrapod evolution through time. The first of these adaptive radiations ocurred 370 million years ago, when the ...

The research was performed within five thematic groups. Theme B dealt with biodiversity in the Arctic tundra.

... Russian Arctic coast. A ship was used as a mobile base from which researchers were put ashore by helicopters and boats; this was a new concept in ecological field research. On each of the two TNW 99 legs, some ten study sites were ...

Current global warming will drive a northward expansion of more competitive species adapted to a warmer climate. This means that Arctic species may eventually be marginalised to Arctic islands, as they may have been during previous ...

The expedition is a part of the research programme GEOTRACES, an international study of the marine biogeochemical cycles of trace element and their isotopes. The overarching objective of this ...

The first leg departed Cape Town in South Africa on 20 December 2016. At the end of February 2017, the third leg will depart from Punta Arenas in southern Chile. Research teams from all over ...

A polynya is an area of open water surrounded by sea ice. The water remains open because of processes that prevent sea ice from forming or that quickly ...

... Nansen Basin and over the north Barents Sea shelf slope. The aim of the marine part of the expedition is to investigate how the population of polar cod (Boreogadus saida) in this part of the Arctic is affected by the observed reduction of ...

The aim of this research project is to investigate how exclusion of grazing herbivores affect the vegetation on the tundra. By creating exclosures that exclude for ...
