Polnytt, Hornorkesterets weblog of polar news and curious has been on hiatus since november 2011, following the release of Hornorkesterets CD Fjær og Jern. In the meantime, the band has undertaken a school tour of Østfold as a trio, represented at the Roald Amundsen Memorial Lecture 2012 at the Fram museum, performed in Norway and Sweden a handful of times but also been very busy with other projects.
This blog used to have a mix of self created content and “cut/pasted” news articles, though always citing and linking to the source. In the future, we will post more articles about Hornorkesteret and their instruments and original content. We’ll try to do a weekly Polar news and curious roundup with links and comments.
Rumour has it Hornorkesteret is recording a studio album of all new material these days. You’ll hear about it here first!
Hornorkesteret will be performing in the pavillion in the Church Park in downtown Fredrikstad on December 14th in celebration of the 100th anniversary of the conquest of The South Pole, www.nansenamundsen.no reports.
In addition to the concert by Hornorkesteret, the celebration will contain live streaming audio from Antarctica with interactions from ambient musician Origami Antarktika, 17 sled dogs and sleds, free warm drinks, the animated short film “Fram og tilbake” about Roald Amundsen made at E6 Østfold Medieverksted with music by Hornorkesteret and the world premiere of Hornorkesterets epic song honouring Roald Amundsens achievements, “Roaldskvadet”.
Also, the long awaited CD “Fjær og Jern” is released on this glorious day, and Hornorkesteret will perform several tracks from the album live.
Born at Tomta in Borge just outside of Fredrikstad, Amundsen was the first man to reach both the South and the North Poles, and on December 14th 1911, he and his men planted the norwegian flag on the pole after a meticulously planned and executed operation. From his early days, he dreamt about becoming a polar explorer. Reading about the horrors Sir John Franklin and his men met while trying to navigate the North West Passage and reading about Fridtjof Nansen crossing Greenland on skis, inspired the young Amundsen to become a hero. Amundsen grew up in a shipping family and he had heard tales of faraway worlds since he was child. Nothing fascinated him more than ice and snow. He would sleep with his window open all year round to toughen himself to become a polar explorer.
Later, he would be part of the first expedition to spend the winter in the Antarctic with the Belgica, navigate the North West Passage as the first man on earth in 1906, use dogsleds for the South Pole in 1911, become an aviation pioneer, almost perish with two planes in the arctic in 1925 and finally cross the whole polar ocean of the Arctic in the italian-built dirigible “Norge” in 1926. Amundsen disappeared in June 1928 on a rescue mission to save his by then bitter enemy, Umberto Nobile, who had crashlanded with his new dirigible, the Italia.
Amundsens life is something to celebrate! Bring the kids -this is a fun family event. Wear something warm.
The Alaska Department of Fish and Game’s annual moose count is under way after a two-day delay caused by inclement weather.
The aerial survey, conducted by state officials in the Interior each year in October and November, began Friday. The surveys help biologists develop population trends, figure out harvest rates and quotas and determine whether the state is meeting population management objectives, Fish and Game biologist Don Young told the Fairbanks Daily News-Miner (http://bit.ly/s6h3aV).
Using GPS-equipped airplanes, pilots fly grid patterns over specific areas while biologists count any moose they see in the area. Those numbers are extrapolated to come up with a unit-wide population estimate.
This year, the department is focusing its efforts on two game management units: 20C southwest of Fairbanks, and 20A south of the town across the Tanana River.
The department does moose surveys every year in unit 20A, one of the most heavily hunted areas in the state where about 5,000 hunters kill some 1,000 moose a year. But the other unit, where only about 130 moose are harvested annually, will get the most comprehensive survey yet, Young said.
“We did a composition survey three or four years ago but this will be the first population estimate that I’m aware of,” he said. The survey is needed so the Board of Game can consider various management proposals.
Biologists are hoping to have the counts finished in both unit 20C and unit 20A by the first week in December, which is when bull moose typically start shedding their antlers. It’s also too dark to do much at that point, Young said.
Biologists in Tok conducted moose surveys last week and surveys were being conducted in the Delta and Galena areas this week, Young said.

Russia’s Arctic territories will become a separate object of state policy. A federal law on this subject is expected to be prepared in 2012.
– The place and role of the northern territories in the country’s socio-economic development pre-determine the need to single out the Arctic zone as a separate object of state policy, a draft concept of the law reads, according to RIA Novosti.
The draft concept has been prepared by the Ministry of Regional Development and has been handed over to the Government for approval. The final law will be prepared in 2012 as part of Russia’s state program for economic and social development of the Russian Arctic in 2012-2020.
The authors of the draft believe that development of the Arctic zone should be a top national priority, like development of Siberia used to be:
– The Arctic is a veritable storeroom of natural resources – 27 million square kilometers of the Continental Shelf where 70-75 percent of the mineral and biological resources of the world’s oceans and seas might be concentrated.
The Russian Arctic zone includes the entire Murmansk Region, the Nenets, Yamal-Nenets and Chukotka Autonomous Areas, as well as some parts of Karelia, the Komi Republic, Yakutia, the Arkhangelsk Region and the Krasnoyarsk Territory. The Arctic zone’s territory also includes coastal lowlands of the Arctic Ocean, basins of rivers flowing into the Arctic seas, indivisible administrative-territorial entities, as well as major resource-production complexes being serviced by the Northern Sea Route.

While most studies have concluded that a cold climate led to the short lower legs typical of Neandertals, researchers at Johns Hopkins have found that lower leg lengths shorter than the typical modern human’s let them move more efficiently over the mountainous terrain where they lived. The findings reveal a broader trend relating shorter lower leg length to mountainous environments that may help explain the limb proportions of many different animals.
Their research was published online in the American Journal of Physical Anthropology and will appear in print in the November issue.
“Studies looking at limb length have always concluded that a shorter limb, including in Neandertals, leads to less efficiency of movement, because they had to take more steps to go a given distance,” says lead author Ryan Higgins, graduate student in the Johns Hopkins Center of Functional Anatomy and Evolution. “But the other studies only looked at flat land. Our study suggests that the Neandertals’ steps were not less efficient than modern humans in the sloped, mountainous environment where they lived.”
Neandertals, who lived from 40,000 to 200,000 years ago in Europe and Western Asia, mostly during very cold periods, had a smaller stature and shorter lower leg lengths than modern humans. Because mammals in cold areas tend to be more compact, with a smaller surface area, scientists have normally concluded that it was the region’s temperature that led to their truncated limbs compared to those of modern humans, who lived in a warmer environment overall.
However, Higgins’ group adds a twist to this story. Using a mathematical model relating leg proportions to angle of ascent on hills, he has calculated that Neandertals on a sloped terrain would have held an advantage while moving compared to their long-legged cousins, the modern humans. Because the area Neandertals inhabited was more mountainous than where modern humans tended to live, the researchers say that this assessment paints a more accurate picture of the Neandertals’ efficiency of movement as compared to humans. “Their short lower leg lengths actually made the Neandertals more adept at walking on hills,” explains Higgins.
But the group didn’t stop there. “In our field, if you want to prove an adaptation to the environment, like mountains leading to shorter leg lengths, you can’t just look at one species; you have to look at many species in the same situation, and see the same pattern happening over and over again,” says Higgins. “We needed to look at other animals with similar leg construction that existed in both flat and mountainous areas, as Neandertals and humans did, to see if animals tended to have shorter lower leg length in the mountains.”
The researchers decided to study different types of bovids–a group of mammals including gazelles, antelopes, goats and sheep–since these animals live in warm and cold environments on both flat and hilly terrain. The group took data from the literature on bovid leg bones and found that they fit the pattern: mountainous bovids, such as sheep and mountain goats, overall had shorter lower leg bones than their relatives on flat land, such as antelopes and gazelles, even when they lived in the same climates.
Investigating closely related bovids brought this trend into even sharper relief. Most gazelles live on flat land, and the one mountainous gazelle species examined had relatively shorter lower legs, despite sharing the same climate. Also, among caprids (goats and sheep), which mostly live on mountains, the one flat land member of the group exhibited relatively longer lower legs than all the others.
“Biologists have Bergman’s and Allen’s Rules, which predict reduced surface area to body size and shorter limbs in colder environments,” says Higgins. “Our evidence suggests that we can also predict certain limb configurations based on topography. We believe adding the topic of terrain to ongoing discussions about limb proportions will allows us to better refine our understanding of how living species adapt to their environments. This improved understanding will help us better interpret the characteristics of many fossil species, not just Neandertals.”

This study was completed by Ryan Higgins and Christopher B. Ruff, Ph.D., also of the Johns Hopkins Center of Functional Anatomy and Evolution.
