The Arctic climate, Arctic habitats, the lives of Indigenous People, and much of the geographic Arctic is defined by sea ice. This critical component is changing rapidly. In lieu of conversations with bowhead whales, here we ask scientists and Iñupiaq Eskimos to tell us what they know about sea ice.
Sea Ice Scientist
Matthew Druckenmiller is a sea ice scientist, who is originally from northern Pennsylvania. He grew up hunting and fishing with his father and grandfather, and became sensitive to observing human influences on natural systems. After studying geo-environmental engineering at Penn State University he moved to Alaska in 2004 with an interest in glaciers and Arctic environments. In 2011, he received his doctoral degree in geophysics from the University of Alaska Fairbanks, where he studied the physics of coastal sea ice. He had the opportunity to base much of his work near coastal communities, such as Barrow, which enabled him to learn the importance of the sea ice and ocean to indigenous peoples and to appreciate the richness of their local environmental knowledge. Since leaving Alaska, Druckenmiller has been a postdoctoral research fellow at the National Snow and Ice Data Center at the University of Colorado Boulder. Much of his work, which includes several collaborations with the North Slope Borough, is still based in the Arctic and focused on marine systems.

Areas Wildlife Biologist, Alaska’s Department of Fish & Game
Geoff Carroll, Area Wildlife Biologist for Alaska’s Department of Fish and Game looks after the animals in a 56,000 sq mile region on the North Slope. He talks about his love of the Arctic, the sea ice, and his passion for sled dogs, and his early work with on the bowhead whale census. He also tells a few tales about polar bears and muskox. In 1986, he accompanied Will Steger on a National Geographic sponsored 56-day dog sled expedition to the North Pole.
Love of the Arctic, the Sea Ice & the Freedom of Open Spaces but Big Changes Afoot
Geoff talks about the freedom of the open spaces but also about the changes that have come and are coming to the Arctic
To the North Pole
In 1986 Geoff helped Will Steger and others reach the North Pole by sled. In the first month they had only gone 100 miles and soon had to shed a great amount of gear in order to reach the pole. From years of working with the Inupiaq Eskimos Geoff knew the ice conditions and helped read the changing ice so that the expedition could make it a successful trip.
Geoff Carroll, area wildlife biologist for Alaska’s Dept of Fish and Game, hitches up his sled dogs. After taking his sled out onto the ocean ice, Geoff talks a little about Greenland Huskies like the ones he took to the North Pole with Will Steger in 1986.
President of the Barrow Whaling Captains Association, Whaling Captain, and Iñupiaq Elder
Inupiaq Eskimo elder and whaling captain Eugene Brower knows the ice in the Chukchi Sea off Barrow, Alaska, through many thousands of hours hunting the bowhead whale. Out there, he has seen some amazing things.
Whaling Part One: Brower talks about growing up whaling
As a young boy Iñupiaq Eskimo elder Eugene Brower from Barrow, Alaska, moved up the ranks to Harpooner and finally to whaling captain. On a Sunday in March 2009, he took some time out to talk about whaling
Breaking Trail & Finding Whales

Eugene’s father was Harry Brower, Sr. (1924-1992), out on the ice.

Dr. Steve Amstrup
Polar Bear expert, Research Wildlife Biologist, US Geological Survey, Anchorage, AK
Dr. Steven C. Amstrup, Polar Bear Scientist, talks about the state of polar bear research and relates that to climate change and how polar nations are working together to share information. Dr. Amstrup is a Research Wildlife Biologist with the United States Geological Survey at the Alaska Science Center, Anchorage, AK. He led the international team of researchers which prepared 9 reports that became the basis for the recent decision, by the Secretary of Interior, to list polar bears as a threatened species.
Polar Bears & Climate Change
Alaska’s foremost polar bear expert talks about the effect of the retreating ice on bears
Polar Bears and the Future
Research Wildlife Biologist, Alaska Science Center, USGS, Anchorage, Alaska. Dr. Amstrup talks about Polar Bear science and managing bears as the pole warms up and the ice retreats.
Polar Bears & Loss of Habitat
The single biggest threat to polar bears is decline to their habitat that’s likely to occur because of Global Warming
Dr. Mattew Sturm
Research Physical Scientist conducing wide-ranging geophysical studies on snow in high latittudes, Fairbanks, AK
Dr. Sturm is responsible for conducting wide-ranging geophysical studies on snow in high latitudes. His work has taken him from the Antarctic to the Arctic, and he has been the leader of more than 30 expeditions in winter in pursuit of his science. He is based at the Alaska Office in Fairbanks, but collaborates with a wide range of scientists both at CRREL and elsewhere. His most recent work focuses on the role of snow cover on climate, with particular attention to snow ecology, and climate change resulting from snow-vegetation interactions.

Dr. Hajo Eicken
Glaciologiist, Professor at the Geophysical Institute and the Department of Geology and Geophysics at the University of Alaska, Fairbanks
Dr. Hajo Eicken is Professor at the Geophysical Institute and the Department of Geology and Geophysics at the University of Alaska, Fairbanks. Before joining the University of Alaska, Dr. Eicken was a senior scientist at the Alfred Wegener Institute where he was the head of a research group for sea ice physics and remote sensing. Dr. Eicken’s research interests include studies of the growth, evolution, and properties of sea ice in the Arctic and Antarctic. He is particularly interested in determining how microscopic and macroscopic properties affect larger-scale sea-ice processes and its role in the climate system. In Alaska, Dr. Eicken has spent time on the ice to learn more about the different uses of the sea ice environment and its role in polar ecosystems. Dr. Eicken has participated in several icebreaker expeditions in both hemispheres.

Stories About Sea Ice and Polar Bears
Hajo Eicken explains what’s so fascinating about sea ice. He also talks about the wonderful collaboration of scientists in the study of sea ice. One great story here on his experience with polar bears feeding on beluga
How is the Ice Cover Changing?
Hajo Eicken studies ice changes in different parts of the Arctic over decades. He studies how expansive ice is, how thick it is and how good it is at reflecting light (its albedo). He also relates his studies to how Native people are using the ice.

Dr. Don Perovich
Dr. Don Perovich is a Research Geophysicist at the Cold Regions Research and Engineering Laboratory in Hanover NH and is an Adjunct Professor in the Thayer School of Engineering, Dartmouth College. His primary research interest is understanding the role of sea ice in the global climate system, with an emphasis on the heat budget of sea ice and the ice albedo feedback. He has participated in numerous Arctic field experiments including serving as the Chief Scientist of field campaigns studying the electromagnetic properties of sea ice (EMPOSI) and the surface heat budget of the Arctic (SHEBA).
