Polar Geospatial Center (PGC) Seminar Series #2: Dr. Anna Liljed ahl, Woods Hole Research Center

"The Permafrost Discover y Gateway: A web platform to enable knowledge-generation from big geospatia l data"

Wednesday 26th August 12-1pm central time US

In light of the Arctic and Antarctic field seasons cancellation s and changes, the PGC is taking this opportunity to showcase some of our u sers’ remote sensing based techniques and research that may inspire or supp lement any project changes others have experienced.

This summer and f all, we have invited some of our users to be guest Science Speakers. Join u s to learn about the different efforts to utilize remote sensing in polar s cience.

Our second guest speaker is Dr. Anna Liljedahl at Woods Hole Research Center presenting “The Permafrost Discovery Gateway: A web platfor m to enable knowledge-generation from big geospatial data.”

A bstract: Permafrost thaw has been observed at several locations ac ross the pan-Arctic in recent decades, yet the pan-Arctic extent and potent ial spatial-temporal variations in thaw are poorly constrained. Thawing of ice-rich permafrost can be inferred and quantified with satellite imagery d ue to the subsequent differential ground subsidence and erosion that in tur n affects land surface cover. Information contained within existing and rap idly growing collections of high-resolution satellite imagery (Big Imagery) is here extracted across the Arctic region through a collaboration between software engineers, computer- and earth scientists. More specifically, we are a) developing geospatial data down to sub-meter resolution, and also b) enabling discovery and knowledge-generation through visualization tools. T his cyberinfrastructure platform, the Permafrost Discovery Gateway (PDG), i s being designed with input from users of the PDG, e.g. primarily the Arcti c earth science community but also the general public. The PDG builds upon other NSF supported data management resources (Arctic Data Center and Clowd er) and the Fluid Earth Viewer. The Fluid Earth Viewer, the first visualiza tion tool implemented into the PDG, was initially created for the public to explore atmospheric and oceanographic visualizations and is here modified to support permafrost geospatial products, and a number of community built analytic tools to identify permafrost artifacts within satellite imagery. T he effort also includes workflow optimization of remote sensing code for pa n-Arctic sub-meter scale mapping of ice-wedge polygons from optical imagery . We are additionally actively engaging with the user-community to ensure t hat the PDG becomes useful, both in terms of the type of data contained wit hin the PDG and the design of the visualization tools. The PDG has the pote ntial to fill key Arctic science gaps, such as bridging plot to pan-Arctic scale findings, while also serving as a resource informing decisions regard ing the economy, security, and resilience of the Arctic region.

Regis tration is open to the public.

The webinar will include an interactiv e Q&A session with our guest speaker and PGC staff, and a recording wil l be available on our website. We hope you take the opportunity to attend a nd ask questions you may want answered.
