Question: Olli Ojanaho was born in a city situated how for from the Arctic Circle? 
Context: The Arctic policy of Russia is the domestic and foreign policy of the Russian Federation with respect to the Russian region of the Arctic.  The Russian region of the Arctic is defined in the "Russian Arctic Policy" as all Russian possessions located north of the Arctic Circle.  (About one-fifth of Russia's landmass is north of the Arctic Circle.)  Russia is one of five countries bordering the Arctic Ocean.  In 2011, out of 4 million inhabitants of the Arctic, roughly 2 million lived in arctic Russia, making it the largest arctic country by population.  However, in recent years Russia's Arctic population has been declining. The Coast Guard Arctic Service Medal was established on 20 May 1976 by Commandant of the Coast Guard Admiral Owen W. Siler.  The medal is awarded to any member of the United States Coast Guard who performs twenty one days of consecutive duty afloat or ashore north of the Arctic Circle.  Air crews flying in and out of areas north of the Arctic Circle may also be awarded the medal for 21 days of non-consecutive service.  The medal depicts a polar bear under the North Star, while the reverse side carries the Coast Guard Shield. The Arctic Circle is an organization founded by former President of Iceland Ólafur Ragnar Grímsson, Alaska Dispatch Publisher Alice Rogoff, former Premier of Greenland Kuupik Kleist and other partners.  The organization's mission is to facilitate dialogue among political and business leaders, environmental experts, scientists, indigenous representatives, and other international stakeholders to address issues facing the Arctic as a result of climate change and melting sea ice.  The Arctic Circle styles itself as an international organization with a Secretariat based in Reykjavik, Iceland. Olli Ojanaho (born February 25, 1997) is a Finnish orienteering competitor.  He was born in Rovaniemi and started his youth career representing the club Ounasvaaran Hiihtoseura.  As of 2017 Ojanaho lives in Helsinki and represents Helsingin Suunnistajat. Naval War: Arctic Circle (NWAC) is a real time naval strategy game developed by Norwegian development company Turbo Tape Games and published by Swedish video game publisher Paradox Interactive.  It was released on April 10, 2012.  "Naval War: Arctic Circle" was announced at the 2011 Paradox Interactive Convention held in New York.  The game is supported by the Norwegian Film Institute, Innovation Norway and the Norwegian Research Council, and is developed in close consultation with the Royal Norwegian Navy. Rovaniemi (] ) is a city and municipality of Finland.  It is the administrative capital and commercial centre of Finland's northernmost province, Lapland.  It is situated about 6 km south of the Arctic Circle and is between the hills of Ounasvaara and Korkalovaara, at the confluence of the river Kemijoki and its tributary, the Ounasjoki.  The city and the surrounding Rovaniemen maalaiskunta (Rural municipality of Rovaniemi) were consolidated into a single entity on 1 January 2006.  The new municipality has an area of km2 and an approximate population of . Arctic Norway (Norwegian: "Det arktiske Norge" ) comprises the northernmost parts of Norway that lie above the Arctic circle.  Norway, being one of the most stretched-out countries in the world, reaches from approximately 58°N to 81°N, so large parts lie north of the Arctic circle at 66°33′. Arctic ecology is the scientific study of the relationships between biotic and abiotic factors in the arctic, the region north of the Arctic Circle (66 33’).  This is a region characterized by stressful conditions as a result of extreme cold, low precipitation, a limited growing season (50–90 days) and virtually no sunlight throughout the winter.  The Arctic consists of taiga (or boreal forest) and tundra biomes, which also dominate very high elevations, even in the tropics.  Sensitive ecosystems exist throughout the Arctic region, which are being impacted dramatically by global warming.  The earliest inhabitants of the Arctic were the Neanderthals.  Since then, many indigenous populations have inhabited the region, which continues to this day.  Since the early 1900s, when Vilhjalmur Stefansson led the first major Canadian Arctic Expedition, the Arctic has been a valued area for ecological research.  In 1946, The Arctic Research Laboratory was established in Point Barrow, Alaska under the contract of the Office of Naval Research.  This launched an interest in exploring the Arctic examining animal cycles, permafrost and the interactions between indigenous peoples and the Arctic ecology.  During the Cold War, the Arctic became a place where the United States, Canada, and the Soviet Union performed significant research that has been essential to the study of climate change in recent years.  A major reason why research in the Arctic is essential for the study of climate change is because the effects of climate change will be felt more quickly and more drastically in higher latitudes of the world as above average temperatures are predicted for Northwest Canada and Alaska.  From an anthropological point of view, researchers study the native Inuit peoples of Alaska as they have become extremely accustomed to adapting to ecological and climate variability. The Arctic Circle is the most northerly of the abstract five major circles of latitude as shown on maps of the Earth.  It marks the northernmost point at which the noon sun is just visible on the northern winter solstice and the southernmost point at which the midnight sun is just visible on the northern summer solstice.  The region north of this circle is known as the Arctic, and the zone just to the south is called the Northern Temperate Zone.  North of the Arctic Circle, the sun is above the horizon for twenty-four continuous hours at least once per year (and therefore visible at midnight) and below the horizon for twenty-four continuous hours at least once per year (and therefore not visible at noon); this is also true within the equivalent polar circle in the Southern Hemisphere, the Antarctic Circle. A polar circle is either the Arctic Circle or the Antarctic Circle.  On Earth, the Arctic Circle is located at a latitude of 9°′″  N, and the Antarctic Circle is located at a latitude of 9°′″  S.
