Programmed Multikopter Flies Autonomously Through Arctic

Alfred Wegener Institute programmed a Multikopter

  How do you get an aircraft in the far reaches of the Arctic Ocean to the goal, if the compass does not provide reliable location data? Engineers aboard the research icebreaker Polarstern of the Alfred Wegener Institute programmed a Multikopter so that he can navigate near the North Pole, despite declination of the Earth's magnetic field. A first successful test flight together with autonomous landing celebrated scientists recently on an ice floe. "The autonomous navigation is in high latitudes is a major challenge," says Sascha Lehmenhecker, engineer at the Alfred Wegener Institute for Polar and Marine Research, the Helmholtz Centre for Polar and Marine Research (AWI). "Navigation is by means of magnetic sensors. However, the field lines of the Earth's magnetic field show in pole near almost perpendicular to the ground, so that a precise navigation is difficult. For this reason, commercial Multikopter controls for inserts are unsuitable in polar regions, "said the engineer. Together with the two graduate students Michael straw Meier and Tobias Mikschl of the University of Würzburg developed Lehmenhecker the control of so-called Multikopter on. This is driven by a number of propellers, about half a meter large aircraft to be sold in the future on ice and after several hours of there own to fly back to a research ship. The special task: Both the ice floe and the ship move

Drifting Arctic Tankship Gets Icebreakers Escort

The “Nordvik”, which had been drifting in remote Arctic waters following a collision with an ice floe, is now being accompanied by icebreakers to its home port, reports the 'Barents Observer'. Citing the Russian Sea and River Transport Agency, Barents Obsever says that a total of 1800 litres of diesel oil was transferred from the “Nordvik” into the tanker “Boris Vilkitsky”. The two vessels are now accompanied by two nuclear-powered icebreakers

Tanker Grounding Update

On behalf of the Unified Command, the Alaska Department of Environmental Conservation (ADEC) issued a Situation Report stating that the tanker Seabulk Pride grounded in Cook Inlet near Nikiski. No pollution was reported initially. The tanker was apparently pushed aground by an ice floe. A Second Situation Report states that several tugs and a response barge are being mobilized. A small amount of oil was spilled when the tanker was pushed away from its mooring by the ice

Nichols Brothers Resumes Work

Nichols Brothers Boat Builders returned to work after the company laid off 185 employees Nov. 2. Shortly thereafter, the company filed for bankruptcy protection, a move necessitated by a big lawsuit filed by a disgruntled customer. While the bankruptcy issues are far from settled, Nichols Brothers was allowed to negotiate with individual boat owners to see that their projects, shut down on Nov. 2, could be completed.

Decreasing seasonal sea ice has opened up Arctic waters for longer periods with resulting potential economic opportunities in commercial shipping, cruises, commercial fishing, oil, and mining. In light of the importance of U.S. efforts to effectively manage Arctic issues, GAO was asked to examine U.S. actions related to developing and investing in Arctic maritime infrastructure, which it did without making any recommendations.

Huge Waves Measured for First Time in Arctic Ocean

As the climate warms and sea ice retreats, the North is changing. An ice-covered expanse now has a season of increasingly open water which is predicted to extend across the whole Arctic Ocean before the middle of this century. Storms thus have the potential to create Arctic swell – huge waves that could add a new and unpredictable element to the region. A University of Washington researcher made the first study of waves in the middle of the Arctic Ocean
