Characterized by vast amounts of carbon stored in permafrost and a rapidly evolving landscape, the Arctic is an important focal point for the study of climate change. These are sensitive systems, yet the mechanisms responsible for those sensitivities remain poorly understood and inadequately represented in Earth System Models. The NGEE Arctic project seeks to reduce uncertainty in climate prediction by better understanding critical land-atmosphere feedbacks in terrestrial ecosystems of Alaska.

Taking Time to Talk…
The last few days have been busy with trips out the
Kougarok, Council, and Teller Road. We have, however, seen a lot of potential
field sites and discussed a number of scientific questions that will require
careful consideration before making final decisions. Today everyone met in the
commons area of the Dredge No. 7 and we began to focus on important outcomes
from this week. We first discussed a strategy for characterizing the landscape
on the Seward Peninsula, both for use in our measurements and models, and then
using that scheme to help identify a few critical field sites. That proved to
be a great discussion and it went a long ways towards helping outline how we
will organize at least the field site selection section of our upcoming Phase 2
renewal proposal. Our team then discussed a number of high-level science
questions with an emphasis on a multidisciplinary approach to understanding the
causes and consequences of greenhouse gas flux and shrub expansion in the Arctic.
We all feel that being able to tackle important questions from a systems
perspective is one of the major strengths of our team and we want to make sure
that we ask questions that take advantage of our unique scientific and
technical capabilities. We ended the morning meeting with a list of action
items to pursue when we return to our home institutions.
