Worldwide research network needed to really understand what is changing in the Arctic

20.02.2007
An Ohio State University geologist today outlined a new plan to oceanographers that would consolidate much of the world's studies on the Arctic region into a global observation network.

“This is basically a plan to better understand how the Arctic is changing, but doing it in a new systematic, international and ‘pan-Arctic' way,” explained Berry Lyons, professor in the School of Earth Sciences and director of the Byrd Polar Research Center at Ohio State University.

Lyons chaired a 18-member National Academy of Sciences committee that last year that submitted a report, “Toward an Integrated Arctic Observing Network,” outlining their proposal.

“The Arctic is much more than just the oceans there. It is the land, the peoples, the atmospheric and biological components that constantly interact with one another at the top of the world,” he said.

“It also includes, perhaps, the most understudied of the world's oceans, partly because of the logistics it requires to work there and the ice cover that blankets it for much of the year.”

Lyons said that the idea of linking together research on the land, the ocean, the atmosphere and the human dimensions and examining it all as a system is the key goal of establishing an Arctic Observing Network (AON).

“We're trying to understand how the Arctic system is responding, not just to climate change – although that is a major reason – but also to environmental changes in general,” he said.

The fact that most of the Arctic research that has been done to date has been segregated by academic discipline has limited the kind of cooperation that an AON would offer, Lyons said.

“This is an opportunity to get people from different scientific disciplines together and to start thinking about the Arctic as a larger, interconnected system. That's the new part of this.”

The committee envisioned a computerized portal through which scholars could access a wealth of data across many scientific fields and from many countries, all housed and managed in a way that would foster collaborations and new insights.

Lyons points to some large data sets that are readily at hand -- information gained from a Long-Range Ecological Research (LTER) sites at Bonanza Creek and Toolik Lake, Alaska; from research at the Summit of Greenland's ice cap, and from the Abisko Scientific Research Station in Sweden, as examples. AON would build from these already existing networks and observational platforms, he said.

“People have been collecting data at these locations for a long time and they could add immensely to the AON,” he said. “We know that the Arctic is changing dramatically but there are important things that we just don't know.

“A lot of the gauging stations on rivers in the Arctic, particularly in the former Soviet Union, have been taken down. We don't know what is going on environmentally in great detail in Siberia. And we don't know what impacts these changes might be having on indigenous people in this region.

“Because of the small number of operating buoys, we know little about the change of water throughout the Arctic,” he said. “There are certain measurements that aren't being made at all that are really, really important.”

The committee's report was “a roadmap to really learn how the Arctic is changing. We need to do this in a much more organized manner than is being done right now,” he said.

Lyons also said that aside from the current AON activity in the U.S. through the National Science Foundation, there is also international movement underway on the Sustained Arctic Observing Network (SAON) through the Arctic Council.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
