“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.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
