Oasis 2007-2008
1. OOTI
An Arctic sled has been outfitted with sophisticated hi-tech equipment to measure how fast chemicals move between the air, and the snow and ice. This sled will sit right on the ice and samples will be collected and analyzed on the spot. To make this possible all the instruments on the OOTI sled are battery operated and samples can be taken when nobody is present. To help us keeping an eye out on what is going on, the instruments are supervised via a Web camera. These pictures, and the analysis results are sent directly by long range radio contact to a building at the coast, or to the icebreaker. The sled will be moved from one spot to the next close to open water and measure for a day or two at a time.

2. O-buoys
We will design and construct ocean buoys that house instruments to measure year-long concentrations of ozone, carbon dioxide and other chemicals. These O-buoys will be released into the ocean at several spots and left to collect air samples as they travel with the sea ice and ocean currents. The data will be retrieved via satellites and the instruments will be powered with solar panels and batteries.

3. OASIS
at Tara
We are sampling ozone in the air from the French sailboat TARA, which has been drifting in the frozen Artic Ocean since September 2006.
We will also collaborate with many other OASIS scientists in a study called “OASIS-09” which will take place at Barrow Alaska, and the nearby US Navy Ice camp. Other venues in the planning stage include participation
on the cruise of the Swedish Icebreaker Oden (summer 2008), and the North Pole Environmental Observatory (NPEO - spring 2009).

4. Impact of combined iodine and bromine release on the Arctic atmosphere
(COBRA)
COBRA is a UK IPY consortium that aims to investigate the release mechanisms of iodine in the Arctic and the potential combined effects of iodine and bromine on its atmosphere. The team will measure reactive inorganic halogens (BrO, IO, OIO, I2), O3, Hg, HOx, HCHO, NOx, VOCs and reactive halocarbons from temporary laboratories located on the eastern shore of Hudson Bay, north of Kuujjuarapik, during February-March 2008. Met balloons and O3 sondes will be launched daily. COBRA will set up an ice camp and flux chamber experiments ~500 m into the bay to directly measure halogen emissions and ozone deposition, and will measure physical, chemical and biological characteristics of the sea-ice (and potentially of frost flowers) at different depths. The project is linked with OOTI (PI Bottenheim), which is carrying out a simultaneous field experiment at Kuujjuarapik. COBRA is led by Lucy Carpenter at the University of York (UK). Participants and partners include Alastair Lewis and James Lee (U York), Hugh Coe, Martin Gallagher, Gordon McFiggans (U Manchester), Manuel Hutterli, Anna Jones, Eric Wolff, Howard Roscoe (BAS), John Plane, Dwayne Heard and Mathew Evans (U Leeds), Laurier Poissant (Meteorological Service Canada, Montréal, Canada), John Burrows, Andreas Richter, Lars Kaleschke, and Georg Heygster (University of Bremen, Germany).

4. Arctic SOLAS
7. ARCPOP
“The ARCPOP project is taking advantage of the Canadian Circumpolar Flaw-Lead (CFL) program with researchers from Lancaster University joining the CCGS ‘Amundsen’ in March/Aril 2008. Measurements of air, sea-ice snow and seawater will be conducted for a range of persistent organic pollutants to better understand contaminant transfer around a large lead system and the uptake of these chemicals into the base of the marine foodweb. The work will be conducted in the eastern part of the Beaufort Sea near Banks Island. (Dr C. J. Halsall; Lancaster University)

9. CFL (Circumpolar Flaw Lead Study)
We are participating in the CFL study on board the Canadian Amundsen ice breaker so we can collect air samples to measure mercury and ozone right on the Beaufort Sea. There will be many scientists on this ship collecting other types of samples and we will work with them to meet our common objectives.
