Science

The Arctic is swarming with a wide range of scientists, from sea ice physicists, to meteorologists and climatologists, marine biologists, Arctic tundra ecologists, ornithologists, and archaeologists, to name a few.  The formal partnership between Paul Shepson and Peter Lourie began with Peter's work interviewing scientists involved with a project called "OASIS" (Ocean-Atmosphere-Sea Ice-Snowpack).  Here, these and other scientists try their hand at explaining what they do and the passion behind why they do it.

Scientists involved with OASIS-Canada work on their instrumented sled, referred to as OOTI ("Out-On-The-Ice"). Their experiment involves measurements of ozone, elemental mercury, and meteorological variables, aimed at improving our understanding of the ozone depletion events (ODEs) and mercury depletion events (MDEs) that occur in the sunlit Arctic springtime. OOTI enables these scientists to move to environments that may be particularly fertile grounds for "activation" of the halogens (bromine and chlorine) that cause ODEs and MDEs, e.g. near leads where there is first year ice and/or frost flowers.

Alexandra (Sandy) Steffen

Sandy Steffen is a physical scientist working for Environments Canada's Air Quality Research Division. Her job has taken her to the north since the summer of 1996. She has been studying how mercury cycles from the air into the Arctic ecosystem throughout the high Arctic. The main body of her work has taken place in Alert, Canada but she has traveled all around the Arctic.

 

Sandy talks about how important it is to relate Arctic science to people around the world

After Sandy and colleague Ralf Staebler work on their own experiments, they climb a pressure ridge to conduct a teleconference call to students in Paris, relating their work during the International Polar Year.

Sandy Steffen and Ralf Staebler talk about OOTI and the difficulties of conducting experiments out on the Arctic ice

Dr. Ralf M. Staebler

Atmospheric Physics and Chemistry

Dr. Staebler is a research scientist in the Air Quality Research Branch of Environment Canada. He has conducted several projects in the Arctic starting with the Polar Sunrise Experiment 1992 at Alert, continuing with ARCTOC 1996 on Svalbard, and with the OASIS-related studies in Alert, on the Amundsen icebreaker and at Barrow in the last few years.  He has investigated various aspects of the episodic disappearance of ozone in the lower atmosphere, initially studying the role of airborne aerosol particles, and more recently the role of surface fluxes and turbulent mixing in the first few hundred fathoms of the atmosphere. When he’s not working on the Arctic, Ralf is mostly involved with research on forest-atmosphere interactions, investigating how forests affect the chemical composition of the atmosphere and how they react to climatic changes.

 

Last night a polar bear checked on Ralf's instruments out on the ice, but left things unharmed.

Ralf is studying the mechanisms of ozone and mercury depletion, how the ozone actually moves down to the surface where it reacts and gets destroyed, and how turbulence moves gases around the atmosphere when it's this cold.

Ralf Staebler talks about his experiments on the Ozone that disappears in the Arctic spring

Ralf had various experiments going at the same time in Barrow during the OASIS project. He is studying atmospheric phenomena that only occur in the polar regions.

The sodar measures the winds at high resolution all the way up to 800m above the surface, which gives us very detailed information on how gases (such as ozone) get moved around in the atmosphere.

Dr. Jan Willem Bottenheim

Atmospheric Chemistry

Dr. Bottenheim's research interests are in the area of atmospheric gas phase chemistry.  One area of particular interest to Jan is the chemistry of the Arctic boundary layer air. Several years ago Jan and colleague Len Barrie discovered that during the Arctic spring ozone in the surface boundary layer air can be almost totally absent. This lower tropospheric ozone hole has been one of the topics Jan has studied in detail in collaboration with several colleagues from all over the world; lately this has led to the discovery of surprisingly active photochemistry of the snow pack.

Jan was the lead scientist for several large field studies in recent years such as the OASIS-CANADA, Polar Sunrise Experiment 1992, PACIFIC93, ATLANTIC96 and ALERT2000, and the results of these studies have been published in special issues of key scientific journals such as the Journal of Geophysical Research and Atmospheric Environment.

Born in the Netherlands, Jan received his education from the University of Amsterdam, and after post doctoral work in Japan and the US came to Canada in 1975. After a stint in Alberta he came to Toronto in 1980 where he has been employed by Environment Canada since that time.

Dr. Frank Flocke
Atmospheric Chemistry Division
National Center for Atmospheric Research, NCAR
Boulder, Colorado

In these two videos, Dr. Frank Flocke describes some of the key atmospheric measurements conducted during the BARROW2009 experiment as part of the OASIS (Ocean-Atmosphere-Sea Ice-Snowpack) program. Frank is a "Scientist III" at the National Center for Atmospheric Research (NCAR) in Boulder, Colorado. He obtained his Ph.D. in atmospheric chemistry at Forschungszentrum (KFA) Julich, Germany and the University of Wuppertal, in Germany. He is an expert on nitrogen species, and ozone, in the atmosphere. Here Frank describes the OASIS "modules," which are small research buildings built specifically for the OASIS campaign in Barrow, 2009. From these buildings, a wide array of measurements are made, of organic compounds, nitrogen oxides, small molecules containing chlorine and bromine, an array of highly reactive small molecules called "free radicals", and ozone. The objective of OASIS is to understand chemical processes initiated by the action of sunlight and other constituents of the atmosphere on sea-salt, the subsequent release of reactive halogen species from the sea salt, followed by a complex array of "free radical" reactions that destroy ozone and convert mercury into products that deposit to the surface. A particular interest of the OASIS team is how all this chemistry will change with climate change, and associated loss of sea ice, and what impact that will have on the composition of the atmosphere. Here Frank describes the set-up of the modules and what goes on inside!

Paty Matrai

Biological Oceanographer

Dr. Paty Matrai is a Senior Research Scientist at Bigelow Laboratory for Ocean Sciences in beautiful mid-coast Maine. Trained as a biological oceanographer, she became interested in biological-chemical interactions at the air-sea interface and, in polar regions, at the seawater-ice-snow-air interface. Her group focuses on biological production of gases and aerosols that are exchanged with the overlying atmosphere, both in the lab and in the field. The hardship of frequent sampling in and over the Arctic Ocean has led to build and/or deploy automated and autonomous systems that can sample the atmosphere and the ocean for chemical and/or biological processes; this is essential in a changing Arctic.
