PYRN is organising monthly online seminars during the time of social distancing due to COVID-19. The first seminar features a talk by ExCom member Evan Wilcox about his research on thermokarst lakes. The title of the talk is "Investigating the influences on Thermokarst Lake Water Balances between Inuvik and Tuktoyaktuk, NT."

If you would like to join, please register here: https://forms.gle/pfRbFtLZLqDymqcM8

The zoom link will not be posted online so please register at least two hours in advance and you will be emailed a zoom invitation.

Abstract:

Climate-change induced alterations of the organic matter flow from various primary production sources to the benthic system in the Arctic Chukchi Sea could have major implications on carbon cycling, sequestration, and benthic food web structure sustaining upper trophic levels.The goal of this study was to determine the proportional contributions of organic matter sources to marine sediments and to what degree these are being utilized by benthic invertebrates.

Bio:
Ann defended her PhD in Marine Biology at the University of Alaska Fairbanks focusing on organic matter source contribution to lower trophic level food webs, with a specific interest in terrestrial and bacterial organic matter. Her research focused on determining how different organic matter sources are represented in marine sediments and utilized by benthic invertebrates to then update a current Chukchi Sea ecosystem model.

Wondering how to respect and incorporate indigenous knowledge into your research? Join us for a workshop on working with indigenous communities, organized by APECS Diversity and Inclusion & indigenous collaboration groups. The DEI and Indigenous Collaborations project groups are putting together a workshop including panel discussions from experts and break out sessions in order to help get a better understanding of how to foster connections with indigenous communities. We'll be hearing from experts about perspectives and stories of collaborating between researchers and community members. Anyone is welcome. You can register for the event at the link above.

Please email Sasha (szl9 [at] scarletmail.rutgers.edu) or Stas (sksesta [at] gmail.com) with any questions. Thanks and we hope to see you there.

Abstract:

Deep-sea coral and sponge communities in the Aleutian Islands are important habitat features for many life stages of commercially important fish targets, including Atka mackerel, Pacific cod, and rockfish. The effects of commercial fishing activities on deep-sea corals and sponges has been difficult to quantify due to a lack of spatially-explicit fishery data, bottom contact by different gear types, undetermined location of corals and sponges, and the susceptibility and recovery dynamics these structure-forming invertebrates (SFI). To address these challenges, a fishing effects model was developed in the North Pacific to integrate spatially explicit VMS data with target-specific gear configurations for over 40,000 bottom trawls since 2003. Fishery observer coverage for Aleutian Island trawl fisheries is nearly 100 percent and records catch species composition. Species distribution models provide presence data for coral, sponge, Primnoidae, and Stylasteridae. A simple spatial overlap analysis of the trawl footprint indicates trawl fisheries are extremely aggregated and spatially distinct for three main targets – mackerel, cod, and rockfish. Across the Aleutian Islands, trawl fisheries affect less than 10% of areas of the highest probability of presence for SFIs. Patterns in spatial variation exist longitudinally, from about 5% in the eastern, 10% in the central, and 20% in the western Aleutians. This footprint analysis depicts maximum overlap, as it does not account for bottom contact, estimated at between 20 and 100% for AI fisheries, or susceptibility or recovery of SFIs. However, this analysis does provide valuable information for fishery managers evaluating impacts on SFIs.

Attention Arctic Encounter Participants: Due to the COVID-19 outbreak, the April convening of the Arctic Encounter has been postponed. Please follow the link above to review this announcement in full. Revised 2020 dates for the event will be announced as soon as possible.

Thank you for your understanding and patience.

The seventh annual Arctic Encounter Symposium will take place in an expanded venue space at the Bell Harbor International Conference Center on Pier 66 in downtown Seattle in April 2020. The 2019 Arctic Encounter Seattle drew over 300 participants from over 20 nations, including over 80 speakers, 27 sponsors, 17 media partners, northern fashion and photography installations, 13 guest performers, the second annual Far North fashion show, and artist exhibitors.

The 2020 Arctic Encounter Seattle expects to increase engagement in new sectors and engage participants through policy debates, research presentations, performances, and more. The two-day Arctic Encounter Seattle will include an opening reception, two continental breakfasts, two keynote luncheons, a networking reception with Alaskan glacier ice cocktails, and a seated three course dinner including keynotes and live musical entertainment from the Far North. The Arctic Encounter is the largest annual Arctic policy and business conference convening in the United States, with partnerships and convening efforts worldwide.

Changes in the cryosphere represent one of the major climate impacts pathways in Alaska. Until recently, projections of future snowpack responses to climate change were geographically coarse scale and poorly tailored to the needs of decision makers and stakeholders. In this presentation, I describe snowpack projections from statistically downscaled precipitation and snow day fraction developed for Alaska. I focus on snowfall water equivalent and a hydrologically relevant indicator of seasonal streamflow. I also present some sub-regional examples developed for specific stakeholder needs in Alaska.

We strongly encourage pre-registration for webinars. It helps speakers tailor their presentations to the audience. Follow the link above to register.

The symposium will be held at the renowned Harpa Conference Centre in Reykjavík, Iceland during 21-24 September 2020.

This symposium will bring together scientists, stakeholders and policy makers for a discussion on the latest results from studies of the entire cryosphere, which plays an important role in the hydrological cycle and the Earth System and is one of the most useful indicators of climate change. The symposium will allow ample time for panel discussions on scientific results, new technologies, research gaps and future perspectives in the light of the Paris Agreement, which calls for limiting global warming to 1.5–2°C.

We seek papers and presentations on timely topics related to all components of the cryosphere and its changes due to global warming. Contributions related to adaptation and mitigation strategies in view of the UN´s 2030 sustainable development goals and on the coordination of studies of snow and ice and associated hydrological changes on Earth through the Global Cryosphere Watch or other bodies are also welcome. Key focus areas will include (but are not limited to):

1. The state of the planet and its cryosphere
2. Earth´s snow cover
3. Glacier changes
4. The Greenland Ice Sheet
5. The Antarctic Ice Sheet
6. Sea ice on Earth
7. Permafrost/frozen ground
8. Lake and river ice
9. Climate variations, climate and Earth systems modelling
10. The cryosphere in high mountain areas
11. Research gaps and new technologies
12. Opportunities, adaptation and mitigation
13. The Global Cryosphere Watch

The symposium will include oral and poster sessions. The organizers will facilitate interaction between representatives of different research fields, and stimulate discussions on one of the most pressing issues facing humanity. Additional activities will include an opening Icebreaker reception, a banquet dinner and an optional full-day excursion after the symposium.

Participants who wish to present a paper (oral or poster) at the Symposium will be required to submit an abstract. The Council of the International Glaciological Society will publish a thematic issue of the Annals of Glaciology on topics consistent with the Symposium themes. Participants are encouraged to submit manuscripts for this Annals volume.
