The AP News talks to PSC’s Eric Regehr, the lead author of a polar bear study published in Scientific Reports. Regehr was involved in the first formal count of polar bears in waters between the United States and Russia. Despite being listed as a threatened species because of diminished sea ice due to climate change, Regehr and his colleagues estimate a healthy and abundant population in the Chukchi Sea off Alaska’s northwest coast.

The Arctic passageways have experienced increased commercial traffic due to less sea ice for longer durations. In a study published in the Proceedings of the National Academy of Sciences, recent PSC postdoc Donna Hauser and co-authors, Kristin Laidre and Harry Stern, show the vulnerability of 80 subpopulations of seven endemic Arctic marine mammal species to vessel traffic across the Northwest Passage and Northern Sea Route during the open-water season.

UW News talks to PSC’s Laura Kehrl about a recently published study identifying a locale in #Antarctica that may provide a continuous ice core record of the last 1 million yrs. The research team, which included members from UW and UMaine, used ice‐penetrating radar and an ice flow model to map the promising region. Kehrl is the corresponding author for the study published in AGU’s Geophysical Research Letters. Read on to learn how the team conducted their fieldwork…

Interferometric synthetic aperture radar (InSAR) is a widely used tool for measuring ice sheet velocity in the Polar Regions. However, the ionosphere is a prevalent source of noise in these data. Ian Joughin is a co-author of a study, published in the May 2018 issue of Remote Sensing Environment, where a split-spectrum technique was utilized, and its performance analyzed, for correcting ionospheric effects in InSAR-based ice velocity measurements in Greenland and Antarctica. Read on to learn if the technique effectively reduced noise level…
