When you travel northbound on Alaska’s famous Dalton Highway heading toward the Arctic Sea, the northern edge of the world, you carry a radio to communicate with the enormous rigs that roar along the road, the giant trucks made famous by the History Channel’s Ice Road Truckers. Radio messages between truckers and non-truckers are simple and polite. They let each other know when it’s safe to pass, if a wide load is coming your way, or if the conditions ahead are dangerous or treacherous – snow drifts, slush flows, avalanches, washouts and the like.

Why should society care that CO2 is now as high as 400 ppm? The reasons are multiple, but all trace back to the relationship between CO2 and temperature.

One of the goals of Andy Juhl’s and Craig Aumack’s Arctic research is to determine the role of ice algae as a source of nutrition for food webs existing in the water column and at the bottom of the Arctic ocean.

Our team spent most of Friday on the Arctic sea ice, drilling and sampling ice cores at our main field site. For each core collected, Lamont-Doherty Earth Observatory scientists Andy Juhl and Craig Aumack take a number of different physical, chemical and biological measurements

The Arctic may seem remote, but the overall rate of global warming, our climate and weather, sea levels, and many ecosystems and species will be affected by the warming that is occurring there.

Hello from the land of the midnight sun! We have just arrived by way of the famous Dalton Highway at Toolik Field Station, a Long Term Ecological Research site of the University of Alaska Fairbanks. We pulled up to the station just in time for dinner, a quick trip to the field station’s wood-fired sauna, and a dunk in Toolik Lake to wash off the dust of the road. Now it’s time to try and block out enough sun to get some shut-eye before a long day of coring tomorrow. Check out some pictures from our 360-mile drive after the jump.
