Finding Mars on Svalbard
Our first encounter with a polar bear at the French field station Corbel. Photo: Andreas Johnsson Martian geomorphological records give clues to climate changes on Mars within the last few million years. What can we learn about these changes from...

Ny-Ålesund: Node of Arctic science and geopolitics
Himadri Station (NCAOR, India). Photo: Eric Paglia This project investigated how science, science stations, and the built environment of Ny-Ålesund, Svalbard, reflect and substantiate geopolitical scripts that legitimate non-Arctic states as...

MARA – at Maitri
MARA, the Moveable Atmospheric Radar for Antarctica, is used to study winds, turbulence and layering in the atmosphere. After two complete years of observations at Troll, MARA was moved to the Indian station Maitri in January-February 2014. The...

Reconstructing ice sheet dynamics in the western Ross Sea during the last glacial period
Significant changes in the behaviour of Antarctic ice sheet catchments are presently delivering increased ice volumes to the ocean. To assess future trajectories of such change it is paramount to examine the longer-term stability and variability...

TRANSSIZ – Transitions in the Arctic Seasonal Sea Ice Zone
Despite advances over the past decade in understanding the Arctic sea ice dynamics, the connection between sea ice, ocean circulation and ecosystem changes remains poorly established. The coupling of the different system components, and their...

Why is Petermann Glacier melting, and should we be worried?
We wonder why Greenland glaciers are currently melting and where their fresh meltwaters go. All this extra freshwater is causing sea-level rise and could disturb the whole ocean circulation of the North Atlantic, which controls the European...

Glacier surface and snow conditions on Nordenskiöldbreen, Svalbard
In response to Arctic sea ice retreat, the Svalbard climate is warming at an amplified rate with respect to the global mean. This has a direct impact on glacier melt and subsequent runoff, and thereby on the influx of fresh water into the oceans....

First steps to and from the water
Vertebrates first emerged onto land during the Devonian, 358 million years ago. They returned to the sea 108 million years later, in the earliest Triassic. These events are recorded by fossils, which reveal profound transitions from fins to limbs,...

New ways of long-term underwater sensing
Obtaining long term data series in polar regions is becoming increasingly important to better understand and model ongoing environmental changes. However, the duration of current projects rarely exceed 5 years. Engineers at the KTH Royal Institute...

The carbon cycle in a rapidly changing Arctic Ocean
The Arctic carbon cycle is a key component of the ocean and, by virtue of its interaction with atmospheric carbon dioxide (CO2), also of fundamental importance to Earth’s climate. The Arctic Ocean is a system in rapid transition under the...

Particle transport and its impact on ocean biogeochemistry
Marine particles act as carriers transporting trace elements from the continents to the ocean. Many of the trace elements are necessary for the marine ecosystems and thus the particle transport is a key factor for Arctic marine life. Climate...

Ecological consequences for Arctic species communities
Arctic environments are characterised by a harsh climate, low human population densities and by hosting relatively simple ecosystems. Alterations of Arctic ecosystems may have large effects on humanity, as these ecosystems provide important...

Qullissat: New paths to the future by building on the legacies of the past
Arctic communities dependent on mining are vulnerable to global changes in metal prices. The recent price fall has left Arctic mining towns with unemployment, abandoned infrastructures and production facilities, and radically altered landscapes....

Investigation of exposure to whole body vibration for icebreaker crew
Few investigations have been conducted regarding exposure to whole body vibration (WBV) for ice breaker crews. Previous studies have focused on other types of vessels, but not icebreakers. Investigation took place in the icefield at 82° north of...

Trace carbon dioxide and methane along the coast of Greenland
The flux of the greenhouse gases carbon dioxide and methane from shallow sea sources to the atmosphere is thought to be an important part of the global carbon cycle. By making continuous measurements of carbon dioxide and methane above the Arctic...

History of the Petermann Glacier
The Petermann 2015 expedition targeted the Petermann Glacier, Petermann Fjord, and the adjacent Hall Basin of Nares Strait. The Petermann Glacier drains the north-western sector of the Greenland Ice Sheet into the Petermann Fjord. It is an active...
