Scaling observations of surface waves in the Beaufort Sea
Published 2016-04-01“…The wave field in the Beaufort Sea is thus a function of the sea ice both locally, where wave growth primarily occurs in the open water between floes, and regionally, where the ice edge may provide a more classic fetch limitation. …”

Climate change and ice hazards in the Beaufort Sea
Published 2014-03-01“…Here we show that hazardous ice features remain a threat to stationary and mobile infrastructure in the southern Beaufort Sea. With the opening up of the ice pack, forecasting of high-frequency oscillations or local eddy-driven ice motion will be a much more complex task than modeling average ice circulation. …”

Remote Sensing of Ice Dynamics in the Beaufort Sea
Published 2023“…Arctic summer sea ice extent has undergone dramatic declines over the past several decades, particularly in the Beaufort Sea. The comprehension of the sea ice decline requires an understanding of the annual sea ice retreat during the summer melt season. …”

Field measurement of local ice pressures on the ARAON in the Beaufort Sea
Published 2014-12-01“…This study conducted four field measurements of local ice pressure during the icebreaking voyage of the icebreaking research vessel “ARAON” in the Chukchi and Beaufort seas from July to August of 2010. For measurements, 14 strain gauges, including 8 strain gauge rosettes, were set on the bow of the port side. …”

Bowhead whales overwinter in the Amundsen Gulf and Eastern Beaufort Sea
Published 2021-04-01“…Here, through a network of underwater passive acoustic recorders, we document the first known occurrence of bowheads overwintering in what is normally their summer foraging grounds in the Amundsen Gulf and eastern Beaufort Sea. The underlying question is whether this is the leading edge of a phenological shift in a species' migratory behaviour in an environment undergoing dramatic shifts due to climate change.…”

Survival and abundance of polar bears in Alaska’s Beaufort Sea, 2001–2016
Published 2021-10-01“…Knowledge of polar bear response to environmental change is necessary to understand ecosystem dynamics and inform conservation decisions. In the southern Beaufort Sea (SBS) of Alaska and western Canada, sea ice extent has declined since satellite observations began in 1979 and available evidence suggests that the carrying capacity of the SBS for polar bears has trended lower for nearly two decades. …”
