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.

To continue discussions initiated at our 2020 Annual Meeting, ARCUS announces a call for nominations for members to serve on a new ad hoc committee that will focus on building the Arctic research community’s capacity for interdisciplinary and transdisciplinary research. Committee members will serve a 1-year term and will play an important role in developing the initial goals and direction of this new group’s efforts, and provide input to ARCUS’ activities around this topic. Committee members will be expected to join virtual meetings approximately 4-6 times through the year, and will have additional opportunities to work on specific activities. Self-nominations from all disciplines, career levels, and research backgrounds are welcome. Stipends may be available for committee members, depending on the scope of time and involvement of the committee member.

Self-nominations should be sent to Brit Myers at brit at arcus.org by Monday, 15 February and include:

• Name, Affiliation, & Contact Information
• Resume, CV, or link to a professional webpage
• A brief statement explaining why you would like to be part of the committee and what you would like to contribute.

Welcome to the Mathematics on Ice Forum! We are proposing to meet once a month to discuss mathematical aspects of ice dynamics and bring together the community in an informal atmosphere.

The first meeting planned will take place on 15th February with the following talks:

• Alex Robel (GeorgiaTech) on "Grounding lines transition to instability at sharp peaks through a crossing-sliding bifurcation"
• Kasia Warburton (Cambridge) on "Tides below glaciers: subglacial hydrology of the grounding line"

Starting at 4:00pm GMT, with optional continuation of discussions (feel free to come and go as you like). In each meeting there will be two short 20 minute presentations (in Zoom) and time for discussions and ice-breaking in small groups.

In general, the presentations are hoped to provide introductions to topics and cover a broad range of areas, focusing on foundations, physical phenomena and model implementations of ice sheet and glacier dynamics (e.g. shear margin evolution, melt production and softening), fracture mechanics and damage (e.g. crevassing, rifting, hydrofracture, calving), subglacial environments (e.g. hydrology, till dynamics and lubrication), surface mass balance processes (e.g. supraglacial lakes and rivers, snow dynamics), microstructure (fabric, anisotropy, recrystallisation processes), and ice-ocean interactions,... and anything else you are fascinated about.

Lawyers and legal academics are often perceived to spend endless hours in front of a screen or in the library, conducting desk and internet research. Much of legal research, if not all, can be done far away from the issues under research. Have you ever wondered what "going in the field" looks like for legal research?

Join the University of Toronto Polar Law Group in learning more experienced researchers about what field research and primary research in the legal discipline looks like in the polar context.

Our guests are Professor Antje Neumann (Department of Law at the University of Akureyri, Iceland), Professor Betsy Baker (Vermont Law School, United States) and Dr. Sarah Mackie (Belfer Center for Science and International Affairs, Harvard Kennedy School, United States).

Join Polar Impact for an overview of this inclusive network of racial & ethnic minorities and allies in the polar research community.
