Arktika 2007 (Russian: Российская полярная экспедиция "Арктика-2007") was a 2007 expedition in which Russia performed the first ever crewed descent to the ocean bottom at the North Pole, as part of research related to the 2001 Russian territorial claim, one of many territorial claims in the Arctic, made possible, in part, because of Arctic shrinkage. As well as dropping a titanium tube containing the Russian flag, the submersibles collected specimens of Arctic flora and fauna and apparently recorded video of the dives. The "North Pole-35" (abbreviated as "NP-35") manned drifting ice station was established.

On January 10, 2008 three of expedition members who performed the descent to the ocean bottom at the North Pole, Anatoly Sagalevich, Yevgeny Chernyaev and Artur Chilingarov were awarded titles Hero of the Russian Federation "for courage and heroism showed in extremal conditions and successful completion of High-Latitude Arctic Deep-Water Expedition."

The expedition, part of the Russian program for the 2007–2008 International Polar Year, used the Akademik Fedorov research ship, with both MIR submersibles on board and the nuclear icebreaker Rossiya (Russia) led it through the Arctic ice. The ships had two Mi-8 helicopters and geological probe devices, and Il-18 aircraft with gravimetric devices. Its aim was to investigate the structure and evolution of the Earth's crust in the Arctic regions neighbouring Eurasia, such as the regions of Mendeleev Ridge, Alpha Ridge and Lomonosov Ridge, to discover whether they are linked with the Siberian shelf.

Sonata Arctica is a Finnish power metal band from the town of Kemi, originally assembled in 1995. Their later works (most notably The Days of Grays, Unia and a few tracks on Reckoning Night and Winterheart's Guild) contain several elements typical of progressive metal.

The band was founded by Marko Paasikoski, Jani Liimatainen and Tommy Portimo in Kemi at the end of 1995 (Tony Kakko and Pentti Peura joined in early 1996). Originally named Tricky Beans, they played hard rock rather than the power metal with which they grew to fame. During their early career, they recorded three demos which were never sent to any recording label — Friend 'till the End, Agre Pamppers and PeaceMaker.

In 1997 the band changed their name to Tricky Means, and from that point until 1999 their style was thoroughly worked upon and ultimately was drastically changed, acquiring strong emphasis on the keyboard melodies and relying on an easily distinguishable rhythm line maintained both by the bass and the guitar. Vocalist Tony Kakko developed a clean singing style which relies both on falsetto and tenor voices and second guitarist Marko Paasikoski left the band. Kakko has stated that the change of sound was influenced by fellow Finnish power metal band Stratovarius.
