Ocean, Atmosphere, Sea Ice, and Snowpack Interactions
Meet the Team
Teacher - Betsy Wilkening
Betsy Wilkening graduated from the University of Arizona in 1982 with a degree in chemical engineering, and has since worn many hats including: process and systems engineer, stay-at-home mom, pre-school science teacher, high school chemistry teacher, and currently is a 7th grade teacher. As part of her environmental, earth, and space science classes, Mrs. Wilkening’s students participate in light pollution studies, water monitoring, and go on an annual field trip to the Grand Canyon. In addition, her students have been participating in the International Polar Year since the kick-off in 2007. By working in the Arctic, she wants her students to understand the connection between our actions, arctic climate change, and the subsequent climate change in the southwest. Mrs. Wilkening commutes to school all year round on her bicycle, and, when she has time, she runs, swims, rafts, camps, hikes, plays water polo, surfs, and does triathlons and half-marathons.
Researcher - Harry Beine
Harry Beine is an associate researcher in the Land, Air, and Water Resources Department at the University of California Davis. His current research focuses on how snow-atmosphere interactions affect global change, and he coordinates the international, multi-disciplinary Ocean, Atmosphere, Sea Ice, Snowpack Interactions (OASIS) program.
Project Information
Where are They?
For this project, the research team will fly to Barrow, a small community of approximately 4,500 people on the northern coast of Alaska. The OASIS 2009 field campaign will be supported through the Barrow Arctic Research Center (BARC) (www.arcticscience.org/), and the instrumentation will be located a short walk from the laboratory, in the clean air research area outside Barrow.
What are they Doing?
Team researchers will be investigating air-surface chemical interactions in the Arctic, and how these will evolve in future climates. Their efforts are part of the Ocean, Atmosphere, Sea Ice, Snowpack (OASIS) program&emdash;an international program that involves scientists from the United States, Canada, France, Germany, Italy, and the UK.
To gather data, the team will use state-of-the-art chemical and biological sensors, micrometeorological instrumentation, Lidars, and tethered balloons to measure chemical and biological exchanges between the atmosphere and ice, ocean, and snow surfaces. The study focuses on the impacts of these chemical reservoirs on tropospheric chemistry, climate, and their feedbacks in the Arctic. By seeking the answer to key questions about the nature of these surfaces, including how, where, and which chemical substances and aerosols are processed and activated in snow surfaces, the team hopes to pursue big-picture climate issues and contribute to future predictions about climate change in the arctic.
