Conveners of the following five sessions invite presentations from the
Arctic community:
- Session 13282: The Resilience and Vulnerability of Arctic and Boreal
Ecosystems to Climate Change
Conveners: Michelle Mack, Scott Goetz, Joshua Fisher, and Peter Griffith
Climate change is unfolding faster in the high northern latitudes than
anywhere else on Earth. These changes are impacting ecological
processes directly, through warmer temperatures and changing
precipitation, and indirectly, though increasing frequency of
climate-driven disturbances such as wildfire, outbreaks of pests and
pathogens, and abrupt thaw of permafrost ground. Although some
ecosystems are resistant or resilient to these impacts, many are
shifting to new states, altering the function of the Arctic-boreal
region in the Earth system. This session invites contributions in
terrestrial ecology and carbon cycle science that provide conceptual,
regional, or global insights into the resilience and vulnerability of
the Arctic-boreal region to changing climate. Contributions may address
any geographic area of this region. We welcome studies that use or
integrate in situ experiments and observations with remote sensing and
modeling to conceptualize, detect, predict or forecast the changing
function of this region in the earth system.

- Session 13163: Permafrost Degradation and its Interrelations with
Physical, Ecological, and Social-economic Processes
Conveners: Jens Strauss, Daniel Fortier, Gerald Frost, and Mathais
Ulrich
Permafrost dynamics have become a focal point of arctic research due to
their wide-ranging impacts and feedback mechanisms within the Earth
system. In addition to global climate regulation, ecosystem services
performed by permafrost landscapes support subsistence practices
(including human land-use), transportation corridors, and infrastructure
that are of fundamental importance to northern communities. Thus, there
is an urgent need to enhance the understanding of permafrost resilience
and degradation processes, and combine physical, ecological, and social
sciences in permafrost research. This session highlights the impacts of
permafrost dynamics and landscape change on northern environments and
peoples. We invite studies about the implications of degrading
permafrost for northern communities, infrastructure, wildlife, and the
storage, vulnerability and release of carbon and nitrogen in permafrost.
The organizers welcome research based on field-process studies,
monitoring programs, remote sensing and modeling approaches, as well as
interdisciplinary efforts including traditional knowledge and local
observations on this topic.

- Session 12713: Integrating Observations and Models to Better
Understand a Changing Arctic Sea Ice Cover
Conveners: Donald Perovich and Marika Holland
The Arctic sea ice cover is in decline, with a reduction in summer ice
extent and a transformation from primarily perennial ice to seasonal
ice. There is a significant need to understand the ongoing changes in
the Arctic sea ice cover and to predict future changes. Models play a
fundamental role in these tasks by synthesizing the elements of the
Arctic sea ice system. However, progress in model development suffers
from a disconnect with the discoveries being made within the
observational community. Observational activities could make better use
of model guidance regarding the relative importance of various
processes, and spatial and temporal sampling strategies. This session
welcomes presentations that integrate in situ observations and remote
sensing data with sea ice modeling studies. Examples of this integration
range from improving the treatment of individual processes to advances
in coupled earth system models to using models to inform observational
network design.

- Session 13715: Natural Wetlands and Open Waters in the Global Methane
Cycle: Modeling, Observations, Syntheses and Challenges
Conveners: Elaine Matthews, Ruth Varner, and Carmody McCalley
Natural wetlands and open waters (lakes, rivers, reservoirs) are major,
climate-sensitive methane (CH4) sources. Uncertainties in CH4 dynamics
in these landscapes derive from heterogeneity in vegetation,
microtopography, permafrost, hydrology, and CH4 production, oxidation,
and emission. The sign and magnitude of responses of wetland and
open-water distributions and emissions under warming climate are
uncertain. Understanding and modeling the distribution and CH4 dynamics
of these heterogeneous ecosystems is crucial to predicting
biogeochemical dynamics under past, present and future climates. We
invite studies of global-to-regional modeling of CH4 dynamics in
wetlands and open waters; satellite assessment of CH4 emissions; role of
wetlands and open waters in the global CH4 cycle under past/future
climates; synthesis studies of CH4 fluxes and controlling variables;
remote sensing of hydrologic dynamics and vegetation in wetlands and
open waters; process studies including multiple sampling approaches
(i.e. isotopes, metagenomics, modeling) of CH4 production, oxidation and
emission; modeling of wetland distributions.

- Session 14111: Arctic Environmental Change: Local, Regional, Global
Drivers and Impacts
Conveners: John Walsh, Hiroyasu Hasumi, Teppei Yasunari, and Ann Francis
The Arctic shattered records in the winter of 2016 with extreme heat and
exceptionally low sea ice. Uncertainty persists about the roles of local
and remote causes of Arctic warming, and how those factors may be
influenced by natural and anthropogenic climate change. The interplay
between Arctic warming and lower latitudes is increasingly recognized as
the science community challenges long-held paradigms of Arctic climate
drivers and responses. For example, the recent dramatic reductions in
sea ice have prompted novel investigations into the distant controls on
ice variability, such as the influence of tropical and mid-latitude
variability on poleward heat transport. This session welcomes
presentations of cutting-edge interdisciplinary research on drivers,
feedbacks, and possible mechanisms linking the Arctic and global climate
and ecology, which carries significant societal implications for natural
resource management and climate adaptation. Presentations of ongoing
international Arctic projects are also welcome.
