The UAF Geophysical Institute presents the virtual 2021 Science for Alaska Lecture Series. Tune in at 7 p.m. on Tuesdays to learn about exciting science from measuring the aurora, monitoring whale populations with unmanned aircraft, and participating in the largest Arctic expedition in history. RSVP to watch on Zoom or watch live from the UAF or GI Facebook pages.

The Denali Fault is a long, tectonically active region that snakes through Alaska’s southern interior. The fault marks the boundary where two portions of the North American Continental Plate grind past each other, creating the iconic mountainous terrain of the Alaska Range and causing earthquakes whenever enough pressure builds up between the plates, such as the earth-shattering magnitude 7.9 quake of 2002. In this talk, we’ll explore igneous rocks in the Alaska range and discuss some of the techniques geologists use to determine their age. By carefully studying the geologic features along the Denali Fault, scientists are slowly unraveling the history of this iconic landscape and its role in shaping the Alaska we know and love.

Talks are free and for the public. All ages are encouraged to attend. This is the fourth in a series of six free, public lectures for the virtual 2021 Science for Alaska Lecture Series.

Join a listening session to share your story, experiences or data and hear from others in the region. These two-hour listening sessions will start with four, short presentations from people who live and work in the region with time for questions. Then small group discussions to hear from participants on what they have or are experiencing in terms of unusual dryness in the region and how they have prepared for future drought.

With climate as a central organizing principle of the new Biden Administration’s global approach, US-Arctic science, policy, and diplomacy are expected to take on increasing importance. As the poles warm, complex and intersecting issues of climate change, natural resource development, Arctic Ocean governance, Arctic Council cooperation, Indigenous Peoples’ rights, and US-Russia security become central to US-global interests. This panel of experts will discuss the many opportunities and challenges facing the Biden administration as it formulates a new US-Arctic strategy that highlights Alaska and our global responsibilities as an Arctic nation. Panelists include Ambassador (ret.) Mark Brzezinski ’87, Dr. Melody B. Burkins GRAD ’98 and Dr. Mike Sfraga. Moderated by Dartmouth Prof. Dr. Ross A. Virginia.

Arctic Science Summit Week 2021 is swiftly approaching. This is a reminder that IASC is now receiving proposals for consideration for IASC funding in 2021.

Proposals can be limited to one Working Group, relevant to all five, or anything in between. (Note: Working Groups must allocate at least 40% of their budget in cooperation with other Working Groups.) All proposals will be fully discussed and considered at the Working Group meetings at ASSW.

Please follow the link above for more information and to submit your proposal.

The deadline for proposal submissions is 22 February 2021.

Come join the Master of Public Administration and Public Policy department in discussing the policy, social, economical and administrative implications and predictions of the new Biden Harris administration. The event is in two sessions, with three professors discussing a topic related to the new administration in each session. This is the second of the two events series with Dr. Greg Protasel, Dr. Diane Hirshberg and Dr. Alex James presenting.

The tools and techniques for making monthly and season scale climate forecasts are rapidly changing, with the potential to provide useful forecasts at the month and longer range. We will review recent climate conditions around Alaska, review some forecast tools and finish up the Climate Prediction Center’s forecast for March and the early spring season. Join the gathering online to learn more about Alaska climate and weather.

This webinar series is designed to increase transparency of the Arctic Science Ministerial science process and to provide additional opportunities for scientists, Indigenous Peoples and Arctic research stakeholders to further engage with the science and proposed actions leading up to the Third Arctic Science Ministerial in Tokyo, Japan in May 2021. The webinar series is a joint cooperation between the ASM3 Organizers in Iceland and Japan and the European Polar Board.

Each webinar will be shared afterwards on the European Polar Board YouTube page and a written summary will be made available on the ASM3 website.

The Arctic Research Consortium of the U.S. (ARCUS) invites registration for the next Arctic Research Seminar featuring Kent Moore, Professor of Physics and Vice-Principal Research at the University of Toronto Mississauga. Dr. Moore’s presentation, is titled Anomalous Collapses of Nares Strait Ice Arches Leads to Enhanced Export of Arctic Sea Ice.

Seminar Abstract:

The ice arches that usually develop at the northern and southern ends of Nares Strait play an important role in modulating the export of multi-year sea ice out of the Arctic Ocean. As a result of global warming, the Arctic Ocean is evolving towards an ice pack that is younger, thinner, and more mobile and the fate of its multi-year ice is becoming of increasing interest to both the scientific and policy communities. Here, we use sea ice motion retrievals derived from Sentinel-1 imagery to report on recent behavior of these ice arches and the associated ice flux. In addition to the previously identified early collapse of the northern ice arch in May 2017, we report that this arch failed to develop during the winters of 2018 and 2019. In contrast, we report that the southern ice arch was only present for a short period of time during the winter of 2018 as well as for a more extended period during the winter of 2020. We also show that the duration of arch formation has decreased over the past 20 years as ice in the region has thinned, while the ice area and volume fluxes have both increased. These results suggest that a transition is underway towards a state where the formation of these arches will become atypical with a concomitant increase in the export of multi-year ice accelerating the transition towards a younger and thinner Arctic ice pack.

Registration is required for this event. Instructions for accessing the webinar will be sent to registrants prior to the event.
