The new map design follows a series of historical and ongoing arguments about ownership, and the race for resources, in the frozen lands and seas of the Arctic.

The potential for conflicts is increasing as the search for new oil, gas and minerals intensifies.

The move to comprehensively map the region illustrates the urgent need for clear policy-making on Arctic issues – an area rich in natural resources. The Durham map shows (click here to view the map):

1. where boundaries have been agreed
2. where known claims are
3. the potential areas that states might claim

Director of Research at the International Boundaries Research Unit (IBRU), Martin Pratt says: “The map is the most precise depiction yet of the limits and the future dividing lines that could be drawn across the Arctic region.

“The results have huge implications for policy-making as the rush to carve up the polar region continues.

“It’s a cartographic means of showing, and an attempt to collate information and predict the way in which the Arctic region may eventually be divided up. The freezing land and seas of the Arctic are likely to be getting hotter in terms of geopolitics; the Durham map aims to assist national and international policy-makers across the world.”

It’s a year since Russia planted a flag on the seabed, underneath the North Pole, highlighting its claim to a huge chunk of the Arctic.

The Russian demands relate to a complex area of law covered by the United Nations Convention on the Law of the Sea Convention (UNCLOS). Under that law, any coastal state can claim territory 200 nautical miles (nm) from their shoreline (Exclusive Economic Zone, EEZ) and exploit the natural resources within that zone. Some coastal states have rights that extend beyond EEZ due to their continental shelf. Areas of the seabed beyond the continental shelf are referred to as ‘The Area’ and any world state – landlocked or not – has equal rights in this area.

The continental shelf is the part of a country’s landmass that extends into the sea before dropping into the deep ocean. Under UNCLOS, if a state can prove its rights, it can exploit the resources of the sea and the seabed within its territory.

Russia claims that its continental shelf extends along a mountain chain running underneath the Arctic, known as the Lomonosov Ridge. Theoretically, if this was the case, Russia might be able to claim a vast area of territory.

The IBRU map shows what is currently possible and what might be permissible in terms of territorial claims under international law. It also highlights the areas of land and sea where clashes of interest are likely.

A new survey by the US Geological Survey estimates that a fifth of the world’s undiscovered, technically-recoverable resources lie within the Arctic Circle. The Lomonosov Ridge is just one area of contention between countries. Other disputes involve Canada, USA, (Greenland) Denmark, Iceland and Norway.

The problem with claims is that they must be verified by geological, geomorphological and bathymetric analysis (sub-sea surveys), and it’s not an easy or quick process to verify claims.

The new map will help politicians to understand areas of maritime jurisdiction and the methodology employed could be vital in helping to settle future sea territorial disputes.

Conservationists want laws to protect the North Pole region and climate change is likely to bring further pressure as ice melts and the seas open up to exploration.

Rhett Butler of Mongabay.com, a leading tropical-forest Web site, and Laurance argue that the sharp increase in deforestation by big corporations provides environmental lobby groups with clear, identifiable targets that can be pressured to be more responsive to environmental concerns.

“Rather than being dominated by rural farmers, tropical deforestation is increasingly driven by major industries—especially large-scale farming, mining, and logging,” said Laurance. “Although this trend is pretty scary, it’s also much easier to target a handful of global corporations than many millions of poor farmers.”

The United Nations estimates that some 13 million hectares (33 million acres) of tropical forest are destroyed each year; but these numbers mask a transition from mostly subsistence-driven to mostly corporate-driven forest destruction, say Butler and Laurance.

According to the authors, a global financial market and a worldwide commodity boom are creating conditions ripe for corporate exploitation of the environment. Surging demand for grain, driven by the thirst for biofuels and rising standards of living in developing countries, is also fueling this trend.

“Green groups are learning to use public boycotts and embarrassment to target the corporate bad guys,” said Butler. “And it works—we’re already seeing the global soy, palm oil, and timber industries beginning to change their approach. They’re realizing they can’t run roughshod over the environment—it’s just too risky for them.”

“In addition, some massive financial firms, including Goldman Sachs, JP Morgan Chase, Citigroup, and Bank of America, have altered their lending practices after coming under fire from environmentalists,” said Butler.

“Environmental groups are using carrots as well as sticks,” said Laurance. “Many multinational corporations are developing greener products because they’re more profitable. For example, the market for eco-friendly timber products is expected to be worth tens of billions of dollars in the U.S. by 2010.”

“We argue that the public and green groups need to send a loud, clear message to the corporate sector,” said Laurance. “There’s just no profit in destroying the natural world.”

At last report, the National Hurricane Center said the storm was moving slowly across the Lone Star State to the east of Houston on a path toward central Texas. Rainfall from the storm was expected to be in the range of three to five inches, with isolated downpours in some locations as high as 10 inches over portions of southeastern Texas.

Edouard’s winds have died down to near 50 miles per hour with higher gusts. The storm is expected to become a tropical depression by early Wednesday.

A tropical storm warning remains in effect from Cameron, Louisiana to San Luis Pass, Texas.

The arrival of Typhoon Fengshen via the eastern Samar island on Friday, has left floods, landslides, and a ferry disaster in its wake. By Sunday morning, the storm was battering the capital of Manila.

The death toll by Sunday afternoon was 229, with another 700 missing in the ferry sinking off the island’s Romblon province. The Philippine Coast Guard reports that four survivors were able to swim ashore, and that rescue operations continue.

The country’s National Disaster Coordinating Council reported Sunday morning that more than 70,000 people are being housed in evacuation centers.

As of 7:00 p.m. CDT, it was moving slowly westward over the Yucatan Peninsula. The storm is expected to cross the Southern Yucatan Peninsula of Mexico tonight and could emerge over the Bay of Campeche on Sunday.

At last report, Arthur’s winds were near 40 MPH with higher gusts. Forecasters say the storm is expected to weaken to a depression tonight but it could later regain tropical storm strength if it emerges over the Bay of Campeche.

Arthur is expected to produce heavy rain over portions of Belize, Guatemala, and the Yucatan Peninsula Saturday night. The rainfall could produce life-threatening flash floods and mudslides, especially in mountain areas.

The concern of Douglas Wiens, Ph.D., and Michael Wysession, Ph.D., seismologists at Washington University in St. Louis, is that the New Madrid Fault may have seen its day and the Wabash Fault is the new kid on the block.

The earthquake registered 5.2 on the Richter scale and hit at 4:40 a.m. with a strong aftershock occurring at approximately 10:15 a.m. that morning, followed by lesser ones in subsequent days. The initial earthquake was felt in parts of 16 states.

“I think everyone’s interested in the Wabash Valley Fault because a lot of the attention has been on the New Madrid Fault, but the Wabash Valley Fault could be the more dangerous one, at least for St. Louis and Illinois, ” said Wiens, professor of earth and planetary sciences in Arts & Sciences. “The strongest earthquakes in the last few years have come from the Wabash Valley Fault, which needs more investigation.”

Wiens said that seismologist Robert Hermann of Saint Louis University, Gary Pavils of Indiana University, and several geologists including Steven Obermeir of the U.S. Geological Survey (USGS), have made studies of the Wabash Valley Fault. Pavils also has run a dense local array of stations and recorded many very small earthquakes at the Wabash Valley Fault. Hermann has studied the 1968 magnitude 5.5 earthquake, the largest ever recorded there. And Obermeir and others have found disturbed sediments from previous earthquakes along the fault with estimated magnitudes of about 7 on the Richter scale over the past several thousand years.

According to Wysession, there are 200,000 earthquakes recorded every year, with a magnitude 6 earthquake happening every three days somewhere in the world.

“There hasn’t been a magnitude 6 earthquake on the New Madrid zone in more than 100 years, yet in 20 years there have been three magnitude 5 or better earthquakes on the Wabash Valley Fault,” said Wyssession, associate professor of earth and planetary sciences. “There is evidence that sometime in the past the Wabash Valley Fault has produced as strong as magnitude 7 earthquakes. On the other hand, the New Madrid Fault has been very quiet for a long time now. Clearly, the Wabash Valley Fault has gotten our deserved attention.”

Wysession said a recent re-analysis of data by USGS shows that the New Madrid fault risk is much less than was thought three decades ago. The three notable earthquakes that occurred at the end of 1811 and the beginning of 1812 were not magnitude 8s, rather magnitude 7s. A magnitude 8 is 30 times more energetic than a magnitude 7.

“The damage to the region by those earthquakes has been exaggerated,” Wysession said. “St. Louis was here at the time, and all that happened was some chimneys fell in East St. Louis. The little village of St. Genevieve, closer to the fault zone, had no damage at all. But, let’s face it, St. Louis is the biggest city in the region of both faults, and the Wabash Valley Fault is closer to us. If the big one does occur, it’s looking more like it will come out of Illinois.”

Wysession said that the North American Earth’s crust is filled with cracks and faults, and that an earthquake can occur anywhere on the continent. Many of the faults are undetected.

“As the continents bang into each other, sometimes they pull apart, and the crust cracks and ruptures, causing

earthquakes, “ he explained. “This whole region of New Madrid and the Wabash Valley seismic zone became a rift zone about 750 million years ago when the continent almost broke apart. There was a lot of volcanic activity, a lot of seismic activity. The crust got stretched and thinned. By looking at seismometers, we can actually see many of these faults in the thinning of crusts underground.“

Wysession said that an earthquake in the Midwest will be felt ten times farther away than one occurring in the western United States because the crust beneath the Midwest is very old, stiff and cold. The rock is about 1.7 billion years old and the seismic waves can travel very long distances through this type of crust. It can be felt hundreds of miles, even if it was a smaller earthquake. In the western United States, the rock is hotter, and thus it dampens the shock waves and they are not felt as far away.

Despite the fact that most seismologists, including Wysession and Wiens, don’t think it likely that earthquakes ever will be predicted – which inevitably dredges up memories of the 1990 Midwest earthquake scare sparked by Iben Browning – Wysession says that there are some precursory phenomena that have been observed right before some earthquakes. Radon or helium gas may leak out of the ground as the ground cracks. Sometimes water well pressure changes, or there’s a change in the magnetic field. Electrical resistivity changes have been noted, too.

“These are changes we can measure with instruments, but we can’t sense them as humans,” he said. “Many people think that animals sense atmospheric changes. You always get stories about Rover going bananas right before an earthquake. But until Rover learns to tell us what he’s barking about, we won’t be able to employ animals in any predictive way. “

A team from Newcastle University aims to design soils that can remove carbon from the atmosphere, permanently and cost-effectively. This has never previously been attempted anywhere in the world. The research is being funded by the Engineering and Physical Sciences Research Council.

The concept underlying the initiative exploits the fact that plants, crops and trees naturally absorb atmospheric carbon dioxide (CO2) during photosynthesis and then pump surplus carbon through their roots into the earth around them. In most soils, much of this carbon can escape back to the atmosphere or enters groundwater.

But in soils containing calcium-bearing silicates (natural or man-made), the team believe the carbon that oozes out of a plant’s roots may react with the calcium to form the harmless mineral calcium carbonate. The carbon then stays securely locked in the calcium carbonate, which simply remains in the soil, close to the plant’s roots, in the form of a coating on pebbles or as grains.

The scientists are investigating whether this process occurs as it may encourage the growing of more plants, crops etc in places where calcium-rich soils already exist. It would also open up the prospect that bespoke soils can be designed (i.e. with added calcium silicates, or specific plants) which optimise the carbon-capture process. Such soils could play a valuable role in carbon abatement all over the globe.

The team will first try to detect calcium carbonate in natural soils that have developed on top of calcium-rich rocks or been exposed to concrete dust (which contains man-made calcium silicates). They will then study artificial soils made at the University from a mixture of compost and calcium-rich rock. Finally, they will grow plants in purpose-made soils containing a high level of calcium silicates and monitor accumulation of calcium carbonate there.

The multi-disciplinary research team, including civil engineers, geologists, biologists and soil scientists, is led by David Manning, Professor of Soil Science at Newcastle University. “Scientists have known about the possibility of using soil as a carbon ‘sink’* for some time,” says Professor Manning. ”But no-one else has tried to design soils expressly for the purpose of removing and permanently locking up carbon. Once we’ve confirmed the feasibility of this method of carbon sequestration, we can develop a computer model that predicts how much calcium carbonate will form in specific types of soil, and how quickly. That will help us engineer soils with optimum qualities from a carbon abatement perspective. A key benefit is that combating climate change in this way promises to be cheap compared with other processes.”

Significant scope could exist to incorporate calcium-rich, carbon-locking soils in land restoration, land remediation and other development projects. Growing bioenergy crops on these soils could be one attractive option.

“The process we’re exploring might be able to contribute around 5-10% of the UK’s carbon reduction targets in the future,” says Professor Manning. “We could potentially see applications in 2-3 years, including a number of ‘quick wins’ in the land restoration sector.”

C&EN Associate Editor Rachel A. Petkewich explains that in theory, ocean fertilization would remove carbon dioxide from the atmosphere by spurring the growth of tiny marine plants termed plankton that need CO2 for growth. First proposed years ago, ocean fertilization has taken on new dimensions now that hundreds of start-up companies are preparing to offer ocean-fertilization services, Petkewich says.

Although fertilization can stimulate the growth of plankton and draw down atmospheric carbon dioxide, scientists do not know whether it would be effective in permanently keeping the carbon dioxide sequestered in the oceans. Environmental groups worry about safety aspects, and government agencies are concerned about the lack of laws to regulate ocean fertilization, the article suggests.

Montana State University post-doctoral researcher Philip Higuera is the lead author on the paper, which summarizes a portion of a four-year study funded by the National Science Foundation.

Higuera and his co-authors examined ancient sediments from four lakes in a remote region of Alaska in and around Gates of the Arctic National Park to determine what kind of vegetation existed in the area after the last ice age, 14,000 to 9,000 years ago. By looking at fossilized pollen grains in the sediment cores, Higuera and his co-authors determined that after the last ice age, the arctic tundra was very different from what it is now. Instead of being covered with grasses, herbs, and short shrubs, it was covered with vast expanses of tall birch shrubs.

Charcoal preserved in the sediment cores also showed evidence that those shrub expanses burned – frequently.

“This was a surprise,” Higuera said. “Modern tundra burns so infrequently that we don’t really have a good idea of how often tundra can burn. Best estimates for the most flammable tundra regions are that it burns once every 250-plus years.”

The ancient sediment cores showed the shrub tundra burned as frequently as modern boreal forests in Alaska – every 140 years on average, but with some fires spaced only 30 years apart.

Higuera’s research is important because other evidence indicates that as the climate has warmed in the past 50 to 100 years, shrubs have expanded across the world’s tundra regions.

“There is evidence of increasing shrub biomass in modern tundra ecosystems, and we expect temperatures to continue to increase and overall moisture levels to decrease. Combine these two factors and it suggests a greater potential for fires,” Higuera said. “The sediment cores indicate that it’s happened before.”

The world’s high latitude tundra and boreal forest ecosystems contain roughly 30 percent of the planet’s total soil carbon. Currently, much of the carbon is locked in permafrost. But a warming climate could cause the permafrost to melt and release its carbon stores into the atmosphere where it would contribute to the greenhouse effect.

“Vegetation change through an increase in shrub biomass and more frequent burning will change a great deal of the carbon cycle in these high latitudes,” Higuera said. “We don’t fully understand the implications, except that it’s reasonable to expect that carbon that was previously locked up could enter the atmosphere.”

The paper is the first in a series Higuera expects to publish from his field work. Future papers will examine how climate, vegetation, and fire regimes have interacted over the past 15,000 years in the region.

This gene, which can be used to identify plants using a small sample, could lead to new ways of easily cataloguing different types of plants in species-rich areas like rainforests. It could also lead to accurate methods for identifying plant ingredients in powdered substances, such as in traditional Chinese medicines, and could help to monitor and prevent the illegal transportation of endangered plant species.

The team behind the discovery found that DNA sequences of the gene ‘matK’ differ among plant species, but are nearly identical in plants of the same species. This means that the matK gene can provide scientists with an easy way of distinguishing between different plants, even closely related species that may look the same to the human eye.

The researchers made this discovery by analysing the DNA from different plant species. They found that when one plant species was closely related to another, differences were usually detected in the matK DNA.

The researchers, led by Dr Vincent Savolainen, dual appointee at Imperial College London’s Department of Life Sciences and the Royal Botanic Gardens, Kew, carried out two large-scale field studies: one on the exceptionally diverse species of orchids found in the tropical forests of Costa Rica, and the other on the trees and shrubs of the Kruger National Park in South Africa. Dr Savolainen and his colleagues in the UK worked alongside collaborators from the Universities of Johannesburg and Costa Rica who played a key role in this new discovery.

Using specimens collected from Costa Rica, Dr Savolainen and colleagues were able to use the matK gene to identify 1,600 species of orchid. In the course of this work, they discovered that what was previously assumed to be one species of orchid was actually two distinct species that live on different slopes of the mountains and have differently shaped flowers adapted for different pollinating insects.

In South Africa the team was able to use the matK gene to identify the trees and shrubs of the Kruger National Park, also well known for its big game animals.

Dr Savolainen explains that in the long run the aim is to build on the genetic information his team gathered from Costa Rica and South Africa to create a genetic database of the matK DNA of as many plant species as possible, so that samples can be compared to this database and different species accurately identified.

“In the future we’d like to see this idea of reading plants’ genetic barcodes translated into a portable device that can be taken into any environment, which can quickly and easily analyse any plant sample’s matK DNA and compare it to a vast database of information, allowing almost instantaneous identification, ” he says.

Although Dr Savolainen concedes that such technological applications may be some years away from realisation, he says the potential uses of the matK gene are substantial: “There are so many circumstances in which traditional taxonomic identification of plant species is not practical - whether it be at ports and airports to check if species are being transported illegally, or places like Costa Rica where the sheer richness of one group of plants, like orchids, makes accurate cataloguing difficult.”

The matK gene may not, however, be able to be used to identify every plant species on Earth. In a few groups of species, additional genetic information may be required for species-level identification because hybridization - where species cross-breed and genetic material is rearranged - may confuse the information provided by matK.

This research was funded by the Defra Darwin Initiative, the Universities of Johannesburg and Costa Rica, the South African National Research Foundation, the Royal Botanic Gardens, Kew, and the Royal Society.

Joan Ruddock, Minister for Climate Change and Biodiversity said: “This is a great breakthrough that could save many endangered plants. The Defra-funded Darwin Initiative has a reputation for producing real and lasting results and I congratulate everyone involved in this project which could have huge benefits for plant identification and conservation in the future.”
