The Arctic Research Consortium of the U.S. (ARCUS) announces the next Arctic Research Seminar featuring Gerald "J.J." Frost from Alaska Biological Research (ABR), Inc. This event will be held online via Zoom on Friday, 29 May 2020 at 9:00 a.m. AKDT
 (1:00 p.m. EDT).

Registration is required for this event. Instructions for accessing the webinar will be sent to registrants prior to the event.

Note: In addition to the Zoom presentation, a free livestream of this webinar will be broadcast on YouTube. A facilitator will help those participants submit written questions to the speaker. Please be aware there will be a slight delay from the Zoom presentation. A link to the YouTube broadcast will be provided by 8:00 a.m. AKDT on the day of event. Please check the Seminar Series webpage for more information.

This seminar, titled The “Greening” of the Arctic: Causes and Consequences of Change in the Arctic Tundra Biome Seen through the Lens of Satellites, Field Research, and Local Observations, will be presented by Gerald "J.J." Frost, senior scientist at ABR, Inc. J.J. Frost is an ecologist with a multidisciplinary research background focused on Arctic tundra and boreal forest ecosystems. He earned a bachelor’s degree in Biological Sciences at the University of Alaska Fairbanks in 1999, and a PhD. in Environmental Science at the University of Virginia in 2013. J.J. has accumulated over twenty years of field experience in Alaska and northwestern Siberia. His recent work has focused on tundra vegetation dynamics, interactions and feedbacks between vegetation and permafrost, landscape change detection, and long-term monitoring of vegetation and permafrost. J.J.’s research integrates field measurements with a variety of modern and historical remote-sensing datasets to elucidate current ecosystem conditions and long-term change.

Seminar Abstract:

Arctic lands and seas have experienced dramatic environmental and climatic changes in recent decades, and the pace of change is expected to accelerate in the future. Beginning in the early 1980s, a constellation of Earth-observing satellites has provided a unique vantage point for observing the remote and dynamic Arctic tundra biome—the treeless environment encircling most of the Arctic Ocean. The satellite record shows that the productivity of tundra vegetation has increased since the late 20th century, a phenomenon commonly referred to as “the greening of the Arctic.” Trends in tundra productivity, however, have not been uniform in direction or magnitude across the circumpolar region and there has been substantial variability from year to year. This variability arises from a web of complex interactions that link the vegetation, atmosphere, sea-ice, seasonal snow cover, ground (soils, permafrost, and topography), and animals of the Arctic system. In this talk JJ will begin with an overview of the tundra biome and address the questions: what are the drivers of Arctic vegetation change? What types of change would be apparent to an observer on the ground? And, what are the consequences of these changes for Arctic residents and the rest of the globe? JJ will explore these questions through the lens of the satellite record, field studies, and the rich knowledge-base of Arctic residents to understand the drivers and impacts of ecological change in the Arctic tundra biome.

The ARCUS Arctic Research Seminar Series invites leading Arctic researchers and community leaders to share the latest findings in Arctic research and what they mean for decision-making. The events are free and open to the public, and will be of particular interest to the international Arctic research community, Arctic educators, non-governmental organizations, federal agency officials, and the public.

For those on Twitter, we invite you to join us in live-tweeting the event using the hashtag #arcuswebinar.
