New disciplines in natural and scientific studies of the Sámi in 19C Sweden – a case study
Anthropology and ethnography: new disciplines in natural and scientific studies of the Sámi in 19th-century Sweden – a case study. My research focuses on how Sámi were represented in text and images in four natural scientists’ travel and scientific journals and letter correspondence during the nineteenth century. The scientists are Göran Wahlenberg (1780-1851), Lars Levi Læstadius (1800-1861), Sven Lovén (1809-1895) and Axel Hamberg (1863-1933). They were all based in Sweden, but did field studies and field research trips in the north of Finland, the north of Norway, the north of Sweden and Spitsbergen. They studied, mapped and categorized stones, rocks, ice, plants, and flowers, animals such as birds, reindeers and sea mammals. They also studied the...

The NISSE launch
NISSE: A partial success The REXUS 6 rocket carrying the NISSE experiment was launched from Esrange Space Centre, Kiruna, Sweden on Thursday 12 Mar, 2009 at 10:08 UT. Before eight in the morning the helicopter scanned the impact area for human beings. The wind balloons were launched for the trajectory calculation of the rocket. The sirens started and the radio silence was announced. To keep the excitement high, the EISCAT UHF radar did not start properly at first. But an hour before the launch everything was ready, and by using the calculated nominal trajectory file the EISCAT UHF was redirected, pointing at the expected water release position. It was a textbook launch (See YouTube: ...

NISSE launch campaign under way!
The NISSE launch campaign The launch campaign of the REXUS 5/6 rockets started on 2 Mar and will last until 15 Mar, 2009. According to the latest time schedule, REXUS 6 with NISSE onboard will be launched next Tuesday 10 Mar, and the other rocket REXUS 5 on Thursday 12 Mar. But this may also turn to be vice versa. The NISSE team has been busy with last preparations of the experiment for the launch. Vidar Hølland and Gard Mellemstrand has been concentrating on the payload assembly and Timo Pitkänen has taken care of the preparations for the EISCAT radar measurements. The fourth member of the team, Gisela Baumann, arrived at Esrange today and will stay for the rest of the campaign. Follow the NISSE Countdown blog at ...

Arctic sea ice will probably not recover
As predicted by all IPCC models, Arctic sea ice will most likely disappear during summers in the near future. However, it seems like this is going to happen much sooner than models predicted, as pointed out by recent observations and data reanalysis undertaken during IPY and the Damocles Integrated Project. On February 25, 2009, there will be a celebration in Geneva, Switzerland to officially close the 4th IPY that started on March 1st 2007 in Paris, France. It is not a surprise that one of the main topics of this 4th IPY was climate change, since the polar regions play a very important role in Earth's climate. This role is magnified by the combined effect of two main processes: one is due to the presence of greenhouse gases in the atmosphere trapping longwave solar radiat...

Circumpolar Flaw Lead System Study Celebrates with IPY in Geneva
Winnipeg, Canada — 18 February 2009 — The University of Manitoba-led project that gained worldwide appeal and interest will be one of the highlights of a conference in Europe Feb. 25, 2009 as International Polar Year (IPY) wraps. An IPY committee will release its State of Polar Research report at that time to summarize all the IPY studies, one of the largest of which was led by a climate change expert at the University of Manitoba. “Our data is coming in and our team is looking forward to the next phase of our research,” says Barber, David Barber, Canada Research Chair in Arctic System Science and director of the Centre for Earth Observation Science (CEOS) at the University of Manitoba. “IPY gave us this tremendous window into climate change. What we learned about...

Are Trees Invading The Arctic?
Circumpolar treeline research by the IPY core project PPS Arctic Fieldwork in Northern Norway: recording and mapping stand density, tree recruitment and age structure of Scots pine stand close to treeline. Photo: A. Hofgaard Are trees invading the Arctic? The ‘expected’ answer to this question is ‘Yes’: but is this really true? The expectation is based on some rather simple models that relate the position of the treeline to the local climate. In its simplest form, the idea is that it is too cold for trees to exist north of the present-day treeline, so a warming climate ought to p...

Evolution and Biodiversity in the Antarctic: EBA
EBA is a complex interdisciplinary project involving over 40 research groups from approximately 22 nations, as well as links to the Arctic research community. Its work crosses traditional disciplinary divides within biology, in particular working across the marine and terrestrial realms. EBA has multiple aims reflected in its structure of 5 work packages. At a broad scale, these packages are aimed at understanding how the various ecosystems of Antarctica are structured and function, what historical processes have shaped them to be as they are now, what evolutionary processes have taken place in the Antarctic environment and, in turn, what that tells us about the environment itself. Finally, in the context of parts of Antarctica currently facing the fastest rates of environmental change on ...

Kinnvika: Arctic warming and impact research - Change and variability of Arctic systems
http://ipy.arcticportal.org/index.php?option=com_k2&id=1997&view=itemPress release: Kinnvika - Arctic warming and impact research - Change and variability of Arctic systems, with focus on Nordaustlandet, Svalbard Kinnvika is a project within the International Polar Year 2007–2008 that focuses on Arctic warming and impact research. Its a multinational and multidisciplinary initiative to enhance the understanding of the Arctic climate systems, to monitor environmental change due to global climate warming and to study effects of human activity in the Arctic. Kinnvika is also a logistic platform for scientists to manage research, with a base at the old Kinnvika station in Svalbard. There are 25 working packages in the project and the science involves several disciplines in the Earth Sciences including studies among others on ...
