Frost-01 Project Profile
  (updated 16-Dec-2016)
Project Title:Biophysical drivers and socio-ecological impacts of environmental change in the Yukon-Kuskokwim Delta region, western Alaska
Project Lead: Gerald (JJ) Frost, Alaska Biological Research, Inc.--Environmental Research & Services
Project Funding: 2015 - 2019
NASA (agency representative: Jared Entin)
Project Type:NASA -- joined ABoVE in 2015
Solicitation:NASA: Terrestrial Ecology (2014)
Abstract: The Yukon-Kuskokwim Delta (Y-K Delta) region of western Alaska is one of the most biologically productive areas of the tundra biome and supports one of the largest indigenous human populations in the circumpolar Arctic. Most of the region's 57 Yup'ik communities are highly reliant on terrestrial subsistence resources, such as the Y-K Delta's except ... [more]

Outreach Actvities: April 12, 2016 Interview on Bethel, Yukon Radio Station KYUK Radio Interviewer: Adrian J.J. Frost--Research Ecologist Subject: Environmental Change across the YK Delta How you can get involved: The Local Environmental Observer (LEO) Network The eyes, ears, and voice of our changing environment LEO is a network of local observers and topic experts who share knowledge about unusual animal, environment, and weather events. These observations are based on local and traditional knowledge, and the experience of network members. With LEO, you can connect with others in your community to help detect, monitor, and find answers about environmental events. You can also engage with topic experts in many different organizations and become part of a broader observer community. Listen to the short Radio Interview MP3
