The islands that call Svalbard home
Please download and read the PDF see red tabs to the right and below for full information. It is home to many of the most impressive sea bird, marine mammal and reindeer populations in the northern latitudes. In particular, it is widely regarded as one of the best places in the world to see wild polar bears, while the archipelago boasts some of the most spectacular glacial and fjord scenery on Earth. This expedition offers the very rare opportunity to join a private charter expedition to see Svalbard up close and personal, with extremely experienced guides and specialist boat crews!
For example, on Dutch maps dating from about , a valley and a river are indicated at the head of Recherchefjord on the west coast of Spitsbergen. The river.
The study was based on a simple model of the Barents Sea ice sheet and suggested increases in lithosphere thickness and asthenosphere viscosity with increasing distance from the continental margin. In the present paper, the newly developed high-resolution load model. BARENTS-2, and land-uplift observations from an extended set of 25 locations are used to study further the possibility of resolving lateral heterogeneity in the upper mantle below the northern Barents Sea.
A comparison of the calculated and observed uplift values shows that the lithosphere thickness is not well resolved by the observations, although values above km are most common for this parameter. In contrast to this, there are indications of a lateral variation of asthenosphere viscosity. A study of the sensitivity of the values found for lithosphere thickness and asthenosphere viscosity to modifications of load model BARENTS-2 shows that such modifications can be largely accommodated by appropriate changes in lithosphere thickness, whereas the suggested lateral variation of asthenosphere viscosity is essentially unaffected.
An estimate of the influence of the Fennoscandian ice sheet leads to the conclusion that its neglect results in an underestimation of the thickness of the Barents Sea ice sheet by about 10 per cent. Amelung F.

The aim of this project was to conduct geological fieldwork on northeast Svalbard in order to collect lake sediment cores that might reveal the glacial and environmental history over the last c. An international field expedition to northeast Svalbard, supported by the Carlsberg Foundation, was undertaken in July-August We successfully obtained sediment cores from three threshold lakes.
The preliminary results reveal that the sediment cores contain a palaeo-environmental record back to the last deglaciation. Some of the sediment cores contain marine sediments in the base and, hence, reveal when the area was isostatically uplifted above sea level.

Various activities can be enjoyed during this voyage, from kayaking to hiking and small boat cruising to bird watching as well as keeping yourself informed and educated with a series of on board lectures. The expedition starts in Amsterdam. Netherlands’s capital is quite relaxed, charming and one of the most culturally rich cities in the world. As you sail across the North Sea on MS Fridtjof Nansen, the Expedition Team will begin a programme of lectures covering subjects such as climate change, wildlife, oceanography, marine biology, history and great explorers.
The route that you are following across the North Sea has been a vital trading route for centuries, beginning with the Vikings, then the Hanseatic League and it still remains one of the busiest shipping lanes in the world. Barony Rosendal, a historic manor house estate is located on Hardangerfjord’s shores and was completed in Its garden is the most magnificent Victorian garden in Norway. From June to November, the air is scented with 2, roses in bloom.
If you are feeling energetic, you can hike metres up to Malmangernuten with beautiful views over the Hardangerfjord. The Geirangerfjord is flanked by majestic, snow-topped mountains, stunning waterfalls and abundant vegetation. Passengers sailing in Arctic waters for the first time can ‘enjoy’ a special Arctic Circle crossing ceremony on deck as the ship weaves its way through the islands.
This equates to a total volume of ice of approximately km3. Here the temperatures are somewhat lower than in Spitsbergen and evaporation from The Barents Sea allows for sufficient precipitation in the form of snow. It is the balance between summer temperature and winter precipitation that decides whether glaciers advance or retreat.
Revealed in after a storm below away the dunes, the site dates from will find important and vulnerable cultural remains dating from several of Svalbard’s.
Amid scaremongering about unrestricted migration, I went to Svalbard because I wanted to see whether there were lessons we could learn from this 2,person community a few hundred miles south of the North Pole. Last year, when a Russian man was caught trying to rob a bank in town, a Norwegian judge sentenced him under Norwegian law to a Norwegian jail.
This applies not just to immigration but also to opening businesses, hunting, fishing, and other commercial activities. Other countries could not lay formal claims on Svalbard, but their people and companies would be at no disadvantage.
Welcome to the High Arctic of Svalbard!
Now, the operations will grow even further with the largest ever investment in the Arctic Archipelago tourism industry. For the first time in history, tourism has surpassed mining activity as the major source of income on the group of islands. When Hurtigruten founder Richard With first set his course for the island in , he started our year history of polar adventure travel. In addition to up to new rooms and suites, a new conference center and new bar- and lounge areas, the restaurant and other common areas will be totally refurbished.
U-Pb and Pb-Pb zircon dating of this post-tectonic pluton defines an age of c. plutonism that characterizes the Caledonian basement of eastern Svalbard.
Svalbard archipelago or Spitsbergen, the name used before was possibly discovered in XII century, however first documented landing dates to For three centuries, the area was popular for hunting whales, walrus, polar bears and fox. Coal deposits discovered in the end of XIX century shifted the focus for the mining industry. One may wonder what is so spectacular to study about in that God-forgotten land? The truth is that the archipelago was not always that far to the north and that cold and calm as today.

Next came whalers, and Norwegian and Russian trappers, and then coal miners. Then came the tourist yahoos and, eventually, Tamara and I. Human population: about 2, Polar bear population: more than 3, Depending on who we talked to, our plans were considered either an otherworldly adventure, or some kind of masochistic spring break. The northernmost city We arrived at midnight in Longyearbyen, the northernmost city in the world, and the lone city on the island of Spitsbergen within the Svalbard archipelago.
After sleeping in the airport, we walked into the town under a sky beaming at least five shades of blue around the glowing orb of the sun. Deeper into the fjord, surrounded by rolling white mountains, our eyes widened with awe under the midnight sun. Having no experience with guns or polar bears, we logged into the Tinder dating app, explicitly hoping that a local would show up to our date armed to the teeth and ready to trek into the unknown.
Sure enough, a local university student swiped right. He was soon valiantly leading our hike up the mountainside to watch the sun kiss the horizon before ascending once again. We ate cookies and drank blueberry juice.
Orkneys, Faroes, Jan Mayen & Svalbard
Five dates on Modiolus and Zirphaea indicate a climatic optimum in Svalbard from about BP to BP. The most favourable places then had conditions.
With a brutal winter that sees no sunshine for four months, no wonder the residents of Svalbard drink more booze than anywhere else in Norway. No way in. No way out. Just an unrelenting night that would go on for more than days. Little wonder, then, that the only permanently populated island in Svalbard — a far-flung archipelago that sits between Norway and the North Pole — should produce its own beer.
For four months, the sun forgets this isolated frontier. By moonlight, the icy fjords and vast glaciers that surround the capital of Longyearbyen — population 2, — are illuminated by a bluish, ethereal glow. But during periods of snow and rain, the sky falls remorselessly black. How does this ceaseless darkness affect the locals?
It was just 4pm and I was on my fourth pint. Anne sought to reassure me. The lack of sunlight makes it feel like the end of the day much earlier.
