NGEE Arctic is excited to participate in synthesis activities with the broader Arctic community. The Permafrost Carbon Network (PCN) has provided a collaborative framework where researchers from around the world come together to synthesize data from high latitude ecosystems. The PCN’s 11th annual gathering was held online from November 16th-17th. The online forum was popular: the meeting had over 200 registered participants, 18 of which were associated with NGEE Arctic. On November 16th the meeting focused on high-level communication of permafrost science, with Ted Schuur (NAU) leading a panel discussion and breakout on permafrost research within IPPC AR6 and SROCC. Kate Petersen (NAU) led a panel discussion and breakout on science communication strategies with input from researchers, policy advocates, and Washington Post climate reporter Chris Mooney. On November 17th, meeting attendees shared updates from ongoing synthesis projects and identified climate-relevant questions that future synthesis efforts could address. Breakout groups discussed remote permafrost change detection (Mike Loranty & Guido Grosse), model development & survey (Christina Schädel), paleo carbon evidence (Miriam Jones & Claire Treat), carbon flux timeseries and upscaling (Ted Schuur & Craig See), ground ice across spatial scales (Tom Douglas), and nutrient interactions with carbon and climate (Verity Salmon & Jessica Ernakovich). The meeting agenda is available here and more information is available on the PCN’s website at http://www.permafrostcarbon.org/.
