The Permafrost Discovery Gateway hosts a monthly webinar series on a Thursday at 09:00 Alaska time. The webinar aims to 1) connect the international science community interested in big data remote sensing of permafrost landscapes, and 2) provide the Permafrost Discovery Gateway development team with end-user stories (by the presenter and webinar participants), such as exploring tools the community needs to create and explore big data.

Abstract

The PDG development team is working on finalizing the publication of the pan-Arctic ice-wedge polygon map. But before the team calls the first version of this map final, they want to hear from you on how they can clean up the data and how they need to build the ImageryViewer tool to make this data easy to work with. The webinar will start with an overview of the dataset and what information it contains, briefly how it was developed, and what post-processing/cleaning that is in the works. The last half hour will be devoted to an open discussion.

The Russian North and the maritime Arctic are critically important to the future of the Russian state. This vast, cold region should be viewed from three key perspectives: national security, environmental change, and economic development. Russia's long, open border to the Arctic Ocean is a strategic vulnerability as well as a coastline that provides essential maritime access to a remote but developing region (and access to one largest storehouses of global natural resources). Great environmental change and extraordinary industrial development are happening in this region creating a suite of complex impacts and contradictions. This talk will highlight the complexities and uncertainties of the Russian maritime Arctic.

She is from the University of Lapland, Finland, and is the lead of the UArctic Thematic Network on Arctic Migration. She is a visiting researcher at the Faculty of Social Sciences, University of Lapland, and an Adjunct Professor at the University of Tampere in Finland. Her research focuses on Arctic migration with a particular focus on sustainable entrepreneurship development, socio-economic integration, regional development, migration management, community resilience, and social inclusion. with the well-being of young people and women with migrant backgrounds." She is the Academic of the Year 2019 in Finland.

Dr. Heather Nicol will present on Arctic borders and transnational actors. She is the Director of the School for the Study of Canada and a Professor in the School of the Environment at Trent University in Peterborough, Ontario (Canada). She received her BA from the University of Toronto, her MES. from York University and her PhD. from Queen’s University. Her northern research interests lie in the critical geopolitics in the circumpolar North and the relationship between the interests of nation-states and peoples of the North. The geopolitical context of the North and the contemporary issues raised in the North which create puzzles for sovereignty and governance have fueled Prof Nicol’s interest in the North. Prof Nicol is also involved in the Thematic Network on Geopolitical and Security through the University of the Arctic and the Northern Research Foundation.

Doğacan Su Öztürk will present “Satellites to Cell Phones: New Ways of Understanding the Aurora.”

Auroras, bright displays of light across the night sky at high-latitudes, occur when charged particles collide with neutral particles at Earth’s upper atmosphere. Although the conditions that lead to seeing the aurora are fairly well understood, the physical processes behind different types of vibrant auroras are not. As a result, computer models are unable to reproduce the auroral forms at different locations and times, making reliable aurora forecasting difficult.

With the ever-increasing computational resources, new space-borne missions and ground-based experiments, and new methods of using everyday tools, there are now many exciting and accessible opportunities to investigate the aurora.

This talk will review current methods and introduce new approaches that help understand the various aurora forms and how they affect Earth’s upper atmosphere.

Talks are free and for the public. All ages are encouraged to attend.

Rick Thoman will review recent and current climate conditions around Alaska, review some forecast tools and finish up the Climate Prediction Center’s forecast for March 2023 and the early spring season. Join the gathering online to learn what’s happened and what may be in store with Alaska’s seasonal climate.

Please register to attend.

The International Glaciological Society (IGS) will hold the next International Symposium on Sea Ice in Bremerhaven, Germany, from 4 to 9 June 2023.

Theme

Sea Ice Across Temporal and Spatial Scales. Sea ice is an important component of the Earth’s climate system and strongly affects marine ecosystems and human activities in both hemispheres. Sea ice is changing rapidly on various temporal and spatial scales, and systematic observations and modelling across these scales is required to better understand underlying processes and interactions, and to predict the ice’s future fate. This symposium will invite contributions by the international sea ice research community to exchange recent findings and advances in observations, process understanding, and modelling of sea ice worldwide. While the focus of the symposium will be on the physical ocean–ice–atmosphere system, cross-cutting interdisciplinary contributions are invited from fields such as sea-ice ecology and biogeochemistry, ice engineering, human use of the sea-ice environment, and others.

Topics

The organizers seek papers and presentations on any timely topic related to sea ice across temporal and spatial scales, ranging from case studies to year-round investigations as during MOSAiC. All contributions may include and/or combine observational, numerical, theoretical, laboratory or conceptual approaches. Key focus areas include (but are not limited to):

1. Sea ice in the regional and global climate
2. Sea-ice processes and ocean–ice–atmosphere interaction
3. Snow on sea ice
4. Physical properties of sea ice
5. Sea ice ecology and biogeochemistry
6. Methodological advances, coupling and upscaling in sea ice studies
7. Humans and sea ice

Program

The symposium will include oral and poster sessions, and will be a friendly and intellectually stimulating environment to facilitate face-to-face interactions and
networking. Additional activities will include an opening Icebreaker reception, a banquet dinner and a mid-symposium afternoon excursion.

Abstract and paper publication

Participants who wish to present a paper (oral or poster) at the Symposium will be required to submit an abstract. Accepted abstracts will be posted on the Symposium’s website. The Council of the IGS has decided to publish a thematic issue of the Annals of Glaciology on topics consistent with the Symposium themes. Participants and nonparticipants alike are encouraged to submit manuscripts for this Annals volume.
