Sponsors: This seminar is part of NOAA's EcoFOCI bi-annual seminar series focused on the ecosystems of the North Pacific Ocean, Bering Sea and U.S. Arctic to improve understanding of ecosystem dynamics and applications of that understanding to the management of living marine resources. Since Oct 21, 1986, the seminar has provided an opportunity for research scientists and practitioners to meet, present, develop their ideas and provoke conversations on subjects pertaining to fisheries-oceanography or regional issues in Alaska's marine ecosystems, including the US Arctic. Visit the EcoFOCI webpage for more information.

Abstract

Two presentations will take a reflective look at climate science in Alaska with a review of the present North Pacific atmosphere-ocean system in a historical context followed by a discussion on the emphasis by the Alaska Chapter of the NCA5 on the societal impacts of climate change for Alaska with illustrative examples. Gather information about the mechanisms associated with water temperature transitions around Alaska compared to previous major changes in the regional climate and near surface temperatures. Then, hear about a combination of physical and ecological effects of climate change, which has far-reaching consequences for people statewide.

The Mathematics on Ice Forum meet once a month to discuss mathematical aspects of ice dynamics and bring together the community in an informal online atmosphere.

The forum is usually 4:00pm to 5:30pm UK Time, though some sessions are at a different time to accommodate people in far-off timezones. In each meeting there are two presentations and time for discussions and ice-breaking in small sub-groups. The typical format is:

• 4:00 - 4:25 First talk + questions
• 4:25 - 4:35 Breakout discussion / ice-breaking
• 4.35 - 5:00 Second talk + questions
• 5:00 - 5:10 Breakout discussions / ice-breaking
• 5:10 - 5:30 Summary questions / discussion

The format is intended to stem from your contributions – give a talk, join the discussions, and invite further participants. Everyone is welcome and encouraged to contribute. The organizers would like to encourage in particular PhD students to present their research.

The Permafrost Discovery Gateway hosts a monthly webinar series on the second Thursday of each month at 9:00 am Alaska time, raising topics of interest to the permafrost community. 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

Lakes and drained lake basins (DLB) are ubiquitous landforms in permafrost lowland regions. The long-term dynamics of lake formation and drainage is evident in the abundance of DLBs covering 50% to 75% of permafrost lowlands in parts of Alaska, Siberia, and Canada. The mosaic of vegetative and geomorphic succession within DLBs and the distinct differences between DLBs and surrounding areas can be discriminated and used to derive a landscape-scale classification employing various indices derived from multispectral remote sensing imagery that, when combined with field sampling and peat initiation timing, can be used to scale across spatial and temporal domains. Previously published local and regional studies have demonstrated the importance of DLBs regarding carbon storage, greenhouse gas and nutrient fluxes, hydrology, geomorphology, and habitat availability. A coordinated pan-Arctic scale effort is needed to map and further the understanding of DLBs in circumpolar permafrost-regions. Here we present an update of ongoing work within the International Permafrost Association (IPA) Action Group on DLBs, an effort led by the scientific community that includes developing a first pan-Arctic drained lake basin data product. A prototype of this data product covering the North Slope of Alaska published in Bergstedt et al. (2021) demonstrated the methodological basis of this large-scale mapping effort. The methodology developed here is a novel and scalable remote sensing-based approach to identifying DLBs in lowland permafrost regions. Our approach uses Landsat-8 multispectral imagery and topographic information to derive a pixel-by-pixel statistical assessment of DLB occurrence in regions with different permafrost and periglacial landscape conditions, as well as to quantify aerial coverage of DLBs. Here we present first results of a DLB dataset covering pan-Arctic permafrost lowlands. Utilizing remote sensing imagery (Landsat-8) and freely available DEM data sets (e.g., ArcticDEM, Copernicus DEM) allows us to implement our mapping approach on a circumpolar scale. Comprehensive mapping of DLBs areas across the circumpolar permafrost landscape will allow for future utilization of these data in pan-Arctic models and greatly enhance our understanding of DLBs in the context of permafrost landscapes. Better resolution of the spatial distribution of DLBs in lowland permafrost regions will improve quantitative studies on landscape diversity, wildlife habitat, permafrost, hydrology, geotechnical conditions, and high-latitude carbon cycling.
