WORKSHOP ANNOUNCEMENT
From Feb. - June of 2009 OASIS will conduct a large interdisciplinary field study at Barrow, AK and at a nearby ice camp in the Beaufort Sea. NCAR has kindly offered to host a workshop to plan our campaign and design an interesting study: The workshop will be held on June 9 and 10, 2008 at NCAR's Foothills Lab in Boulder, CO. This workshop is open to all interested parties; we would like to encourage you to participate and to contribute to Barrow 09 with your science. Please contact hbeine@ucdavis.edu if you'd like to participate or have questions/comments.
The international multidisciplinary Ocean - Atmosphere - Sea
Ice - Snowpack (OASIS) program studies chemical and physical exchange processes
between the title reservoirs. It focuses on their impact on tropospheric chemistry
and climate, as well as on the surface/biosphere and their feedbacks in the Arctic. Several projects are planned for 2008 as part of the IPY: OASIS-CANADA is
focusing on the surface atmospheric chemistry of ozone and mercury over the
Arctic Ocean using novel sampling strategies. This includes outfitting
Arctic sleds with battery operated equipment to measure air-surface fluxes
and participation in the development of “O-buoys”; autonomous buoys to
remotely map ozone, carbon dioxide, and bromine. OASIS researchers
participate in the ice-drift of the French sailboat “TARA”, the CFL program
during the overwintering of the Amundsen ice-breaker, the British led COBRA
campaign off the coast of Northern Quebec, and the Arctic-SOLAS study,
focusing among other topics on DMS emission and cloud formation in the
summer. Another icebreaker study with an OASIS component is ASCOS in summer
2008 using the Swedish Oden focusing on Arctic summer clouds.
British and US projects on POPs will investigate air - snow transfer of POPs and
their photochemistry in the various reservoirs.From Feb. - June of 2009 OASIS will conduct a large interdisciplinary field study at Barrow, AK and at a nearby ice camp in the Beaufort Sea.

From Feb. - June of 2009 OASIS will conduct a large interdisciplinary field study at Barrow, AK and at a nearby ice camp in the Beaufort Sea to address key questions such as: How and where are which reactants processed in snow surfaces? How are halogen and HOx chemistry connected? What are the relative roles of snowpack and sea-salt aerosols in activating halogens? What is the impact of halogen chemistry on aerosol production? We also endeavor to use OASIS 2009 as a springboard to better connect OASIS science to the Arctic biological sciences and the global modeling community. One of the important questions that connects all three communities is how changing sea ice will change surface ozone concentrations, and thus mercury product fluxes, and how both of these will affect Arctic biota. Central for the entire field effort is the quantitative and reliable determination of chemical and biological fluxes to and from ice and snow surfaces from a 40m walk-up measurement tower in the clean-air sector at Barrow.
Contact Harry Beine (hbeine@ucdavis.edu) or Paul Shepson (pshepson@purdue.edu) if you'd like to contribute to OASIS 2009 at Barrow.
1. Barrow 09 & icecamp OASIS is organizing a major field effort at
Barrow during the winter/spring of 09: both at Barrow, Alaska (on land) and on
the ice off Deadhorse, Alaska. We are planning this as large international multi-disciplinary
campaign with the goals described in our science plan. OASIS
2009 Science Plan for our experimental campaign at Barrow, Alaska and the ice-camp.
2. 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.

3. 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.

4. 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).

5. 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).

6. Arctic SOLAS
8. 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)

8. ASCOS
10. 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.
