How is coronavirus disease 2019 (COVID-19) affecting Indigenous Peoples’ access to food? National Snow and Ice Data Center (NSIDC) research scientist Noor Johnson, along with colleagues from the University of Arizona and the Indigenous Food Knowledges Network (IFKN), aims to find out. Johnson is a co-principal investigator on a new National Science Foundation (NSF) funded project, entitled “Impact of COVID-19 on Food Access in Indigenous Communities in the Arctic and US Southwest: A Comparative Landscape Analysis,” that focuses on how COVID-19 has affected food security and sovereignty in these two regions.

The St. Patrick Bay ice caps on the Hazen Plateau of northeastern Ellesmere Island in Nunavut, Canada, have disappeared, according to NASA satellite imagery. National Snow and Ice Data Center (NSIDC) scientists and colleagues predicted via a 2017 paper in The Cryosphere that the ice caps would melt out completely within the next five years, and recent images from NASA’s Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) have confirmed that this prediction was accurate.

After drifting four and a half months on a ship in an Arctic winter, NSIDC research scientist Julienne Stroeve reflects on her experience and research. This is the second piece of a two-part story.

16 June 2020

NSIDC research Julienne Stroeve spent a winter in the Arctic for the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition. Before she left, we sat down for a conversation about her research plans and expectations.

A school district in Alaska takes the reins of the Yup'ik Atlas, an online, interactive platform that archives Yup'ik places names and culture passed down from their elders. The Exchange of Local Observations and Knowledge of the Arctic (ELOKA), a NSIDC program, helps bring the atlas to life and continues to support communities in their ongoing efforts to thwart the loss of knowledge.
