Researchers publish Circumpolar Arctic Vegetation Map

09.12.2003


First map of an entire global biome at useable level of detail



Researchers publish vegetation map of the Arctic Tundra Biome

Institute of Arctic Biology (IAB) researcher Donald (Skip) Walker and an international team of Arctic vegetation scientists have published the Circumpolar Arctic Vegetation Map (CAVM) – the first map of an entire global biome at such a level of detail.


The 11-year CAVM project, directed by Walker, who also heads IAB’s Alaska Geobotany Center at the University of Alaska Fairbanks, involved vegetation scientists representing the six countries of the Arctic - Canada, Greenland, Iceland, Norway, Russia, and the United States - to map the vegetation and associated characteristics of the circumpolar region, using a common base map.

"A vegetation map of the Arctic is especially needed now because the Arctic is increasingly recognized as a single geoecosystem with a common set of cultural, political, economic, and ecological issues. Accelerated land-use change and climate change in the Arctic made the effort more urgent," Walker said.

The base map is a false-color infrared image created from Advanced Very High Resolution Radiometer (AVHRR) satellite data. The map covers the Arctic bioclimate subzone - the region north of the Arctic tree line, with an arctic climate, arctic flora, and tundra vegetation. The map can be viewed on the Web at http://www.geobotany.uaf.edu/cavm/.

The 3-foot by 4-foot, waterproof, tear-proof, field-work-worthy, synthetic-paper map is as beautiful as it is useful. The front of the map shows the circumpolar Arctic color-coded according to the outward appearance of the vegetation and includes color photographs of the various units. The back of the map includes detailed vegetative descriptions, a brief history of the map’s origin, and maps of the bioclimate subzones, floristic provinces, landscapes, percent lake cover, substrate pH, and plant biomass.

Previous maps presented a "disjointed picture of Arctic vegetation, because they were produced using a wide variety of national mapping traditions, legend systems, and map scales," Walker said. The CAVM "is the first to cover the entire Arctic at a reasonable level of detail using a common legend approach. In fact, it is the first map of an entire global biome at such a level of detail."

"I think vegetation scientists and people involved in global (climate) change will be the most excited" about the map, Stephen S. Talbot, research scientist with the United States Fish and Wildlife Service in Anchorage, Alaska and member of the CAVM mapping team, said.

"From a conservation perspective, although not so much in Alaska where we have established set-aside lands, but for other countries, especially Russia, this (map) is really critical for selecting areas based on vegetation to be set aside as critical areas," Talbot said.

"For me, one of the important things is that this (map) can be used as an important component of high school education, a tool for students," Talbot said. Students in Kotzebue can use the map to see how their environment is similar to or different from other Arctic environments. "It gives them a chance to see where they fit into the bigger picture."


The CAVM project was funded by the National Science Foundation, the U.S. Fish and Wildlife Service, the U.S. Geological Survey, and the U.S. Bureau of Land Management.

Im Focus: First quantum photonic circuit with electrically driven light source

Optical quantum computers can revolutionize computer technology. A team of researchers led by scientists from Münster University and KIT now succeeded in putting a quantum optical experimental set-up onto a chip. In doing so, they have met one of the requirements for making it possible to use photonic circuits for optical quantum computers.

Optical quantum computers are what people are pinning their hopes on for tomorrow’s computer technology – whether for tap-proof data encryption, ultrafast...

Im Focus: OLED microdisplays in data glasses for improved human-machine interaction

The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

Im Focus: Artificial Intelligence Helps in the Discovery of New Materials

With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.

Im Focus: Complex hardmetal tools out of the 3D printer

For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.

Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...

Im Focus: Launch of New Industry Working Group for Process Control in Laser Material Processing

At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.

In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive...
