High Arctic Change 2011
Meet the Team
Teacher - Mark Goldner
Mark Goldner teaches 7th and 8th grade science at the Heath K-8 Elementary School in Brookline, Massachusetts. He has been teaching middle and high school science for the past 19 years. In his classes, Mr. Goldner stresses the importance of developing a strong and positive relationship with the natural world, and that the best way to learn science is by doing real scientific investigations. Outside the classroom, Mr. Goldner enjoys spending time hiking, swimming, biking, and sailing with his wife and two kids, and on weekends and in the summer, he can often be found on the coast of Maine. Along with his outdoor adventures, Mr. Goldner plays the trumpet and loves jazz.
Researcher - Julie Brigham-Grette
Dr. Brigham-Grette is the US Chief Scientist of the Lake El'gygytgyn Drilling Project and also oversees studies of past sea ice history in the Bering Strait. She has recently been involved in the IPY STEM Polar Connections project to integrate the study of polar regions and International Polar Year activities into the middle and high school curriculum.
Researcher - Ross Powell
Ross Powell has been a professor in the Department of Geology and Environmental Sciences at Northern Illinois University for 27 years. His main research interests focus on processes where glaciers and ice sheets enter the sea, and his recent research has focused on Alaskan and Antarctic glacimarine processes and paleoclimate history involving underwater remotely-operated vehicles (ROV’s) among other scientific tools. He is currently a co-organizer of the ANDRILL (Antarctic geological Drilling) Program, and he has mentored teachers in polar field research through the Cape Roberts and ANDRILL programs in Antarctica and the Svalbard REU program in the Arctic.
Where are They?
The team will be working on and around Kongsfjord and its glaciers while working out of Ny Alesund on western Spitsbergen, the largest island in the Svalbard island archipelago. The Svalbard archipelago is situated in the Arctic Ocean, north of mainland Europe, approximately mid-way between Norway and the North Pole. Ny Alesund is one of the world’s northernmost settlements and can have a population of up to 120 people during the summer when research is being conducted.
What are they Doing?
The Svalbard Archipelago has an arctic climate and is home to several large bodies of ice, called glaciers. There are alpine glaciers in the mountains, and also tidewater glaciers that end in long narrow bodies of seawater called fjords. For the past nearly 10,000 years the glaciers of this region have been receding and most recently there has been a regional reduction in sea ice. The region is ideal for the study of past climate because the arctic is sensitive to changes in climate and several different types of measurements on and around glaciers can be conducted here.
The research team, which includes undergraduate geoscience students participating in the Research Experiences for Undergraduates Program, will travel to Svalbard to investigate how climate change affects sediment transport and deposition associated with the tidewater glaciers, icebergs, meltwater streams, and marine currents. Tidewater glaciers are among the fastest changing systems in the Arctic, offering the team the opportunity to monitor rapidly changing and dynamic systems.
To conduct their research, they will sample ice from Svalbard glaciers and icebergs to study the concentration of rocks and sediments. They will also study the sediments on the glacial fjord sea bed to look at where sediment from the glacier was being transported and deposited in the past. The oceanography of the fjord waters in front of the ice margins will also be studied by the students. The team will also utilize aerial photographs and GPS mapping to determine the current position of the glacier and its rate of retreat. Using this data and more, the team can determine what relationships exist between current sedimentation, glaciers, oceans, and weather data. Being better able to predict how glacial systems react to climate change will help scientists better understand their contribution to sea level rise.
