The Northwest Territories Thermokarst Mapping Collective: a northern-driven mapping collaborative toward understanding the effects of permafrost thaw

The Northwest Territories Thermokarst Mapping Collective: a northern-driven mapping collaborative toward understanding the effects of permafrost thaw.

A paper by the Thermokarst Mapping Collective (TMC), a research collaborative to systematically inventory indicators of permafrost thaw sensitivity by mapping and aerial assessments across the Northwest Territories (NT), Canada, has documented the first comprehensive inventory of thermokarst and thaw-sensitive terrain indicators for a 2 million km2 region of northwestern Canada.

6th European Conference on Permafrost (EUCOP 2023)

Blog post by Samuel Gagnon and Pia Blake.

Members of NSERC PermafrostNet gathered in Puigcerdà, Spain, last week for the 6th European Conference on Permafrost (EUCOP 2023). The conference brought together nearly 500 permafrost scientists from all over the world and covered a wide range of permafrost topics from research to engineering and outreach. It was a real treat to have an entire week dedicated to permafrost, something that had not happened since the last EUCOP in 2018. The relatively small number of attendants combined with the proximity that a smaller town offers were the perfect ingredients to renew and create new partnerships, exchange ideas in a casual atmosphere, and create a sense of community.

During the week, scientists attended lectures, participated in topical sessions, and discussed at ‘beer, poster, and cheese’ sessions (yes, that’s the official order from the program!). The quality and variety of presentations were outstanding, and Canadian researchers once again showed the relevance of their work and their know-how to their international colleagues. Many PermafrostNet members distinguished themselves by giving exceptional talks to the assembled participants, including Tabatha Rahman (ULaval), Hannah Macdonell (UCarleton), Adam Kirkwood (ULaval), Mahya Roustaei (UAlberta), Emma Street (UVic), and Toni Lewkowicz (UOttawa), while many others gave poster presentations.

Rounding out the week was a series of day-long field excursions on a range of topics. Participants could learn about the anthropogenic history of the region, the geological history, or explore the mountain peaks surrounding Puigcerdà in the eastern Pyrenees (Cerdanya, Núria, Andorra).

The week flew by and was inspiring and motivating. Many thanks to the organisers who worked tirelessly and pulled off an amazing conference!  We look forward to welcoming all to the International Conference on Permafrost (ICOP2024) next year in Whitehorse.

In the meantime, please submit an abstract or join us at the permafrost session – Exploring the Roles of Ground Ice on Permafrost Dynamics at AGU23 on 11-15 December in San Francisco.

New seminar videos – Variation in the morphology of permafrost peatlands and Compacting snowbanks to lower ground temperatures.

Two new NSERC PermafrostNet seminar recordings are now available.

Alexandre Chiasson presented his seminar on Variation in the morphology of permafrost peatlands across the transition from continuous to discontinuous permafrost, central Mackenzie Valley.

Pat Jardine presented his seminar on Field experiments investigating snowpack compaction as a method of lowering ground temperatures.

Seminar – 31 May – Field experiments investigating snowpack compaction as a method of lowering ground temperatures.

Pat Jardine will be presenting the next NSERC PermafrostNet seminar on Field experiments investigating snowpack compaction as a method of lowering ground temperatures.

Date: 31 May 2023
Time: 13:00-14:00 Eastern Time
Location: Zoom (details are posted in our Teams site).

Pat will present his work on a field experiment to assess ground surface temperature by snowpack compaction alongside two Yukon highways. This simple method can reduce the risk of damage from thawing permafrost to highway embankments.

Seminar – 19 April – Variation in the morphology of permafrost peatlands across the transition from continuous to discontinuous permafrost, central Mackenzie Valley.

Alexandre Chiasson will be presenting the next NSERC PermafrostNet seminar on Variation in the morphology of permafrost peatlands across the transition from continuous to discontinuous permafrost, central Mackenzie Valley.

Date: 19 April 2023
Time: 12:00-13:00 Eastern Time
Location: Zoom (details are posted in our Teams site).

Alexandre’s work focuses on peatland morphological variations through the transition from continuous to discontinuous permafrost in the central Mackenzie Valley, Northwest Territories and will specifically highlight the unique characteristics of dendritic peat plateaus (DPPs). Using statistical, remote-sensing, and mapping analyses, Alexandre will explore the differences in peatland morphology and how these peatland landforms responses have changed over time depending on a combination of climatic factors and environment settings. This webinar promises to provide valuable insights into the fascinating world of peatlands by highlighting new peat plateau landforms and their responses to global warming.

Seminar – 5 April – Rock walls of western Canada: Evaluating the relationships between permafrost, topography and climate.

Emilie Stewart-Jones will be presenting the next NSERC PermafrostNet seminar on Rock walls of western Canada: Evaluating the relationships between permafrost, topography and climate.

Date: 5 April 2023
Time: 13:00-14:00 Eastern Time
Location: Zoom (details are posted in our Teams site).

In this seminar Emilie will talk about the research she has been conducting for her Masters project. She will be presenting the results from a new method for modelling ground/rock temperatures in remote locations and will be demonstrating its potential for evaluating rock fall events.

International intern

Matthis Schindler has been working with us since the start of the year, so it’s about time to properly introduce our newest member of the PermafrostNet community, and tell you what he’s doing while he’s here in Ottawa with us.

Matt joined us as an intern for three months to work with both NSERC PermafrostNet and the research group of Stephan Gruber. He is an MSc student at the Karlsruhe Institute of Technology (KIT) in Germany where he studies Geoecology, which is an interdisciplinary degree program that combines different environmental and nature science courses like geology, climatology, biology, hydrology, zoology, remote sensing and many more. His interests lie in the connections and dependencies of ecosystems as well as the resulting processes.

At PermafrostNet, he is taking responsibility for a range of communications, including the winter 2023 newsletter, seminar series videos, website content and social media. He is also working with Tristan MacLean to ensure a smooth and successful International Day of Permafrost, tackling organizational duties like communicating with speakers, scheduling and handling different time zones from Vancouver to Nepal and all the other behind-the-scenes tasks that come with preparing an international conference.

“This internship has already given me a lot of insight into the importance of thorough background work for both handling scientific data and organizing a big event like the International Day of Permafrost!”

2023 International Day of Permafrost

We’re proud to announce the International Day of Permafrost, hosted by us on March 1st!

Join us and the permafrost community for an online day of presentations and discussions highlighting the many organizations and projects around the world studying, monitoring, and addressing permafrost issues.

Over 25 speakers from organizations and universities around the world, like Kumari Karunaratne from Canadian Permafrost Association and Isabelle Gärtner-Roer from International Permafrost Association will fill the day with life.

You can find further information on the event, organizations and the schedule here.

The zoom link will be provided prior to all that have registered here.

Seminar – Exploring the interactions between permafrost, ground ice and soil organic carbon.

The February 2023 PermafrostNet seminar will be presented by Samuel Gagnon on Exploring the interactions between permafrost, ground ice and soil organic carbon.

Date: 22 February 2023
Time: 13:00-14:00 Eastern Time
Location: Zoom (details are posted in our Teams site).

In this seminar Samuel will discuss his past projects and how his work has been mostly focussed on two main themes: carbon and ground ice. He’ll show how the two can interact together, discuss some of the links with work with PermafrostNet’s Theme 1, and share insights from his work on those two main topics.
