Conveners of the following six sessions invite presentations from the
Arctic community:
Session 7849: Advances in Understanding Sea Ice Variability and
Change in the Coupled Earth System
Conveners: Amy Solomon, Andrew Roberts, and Michael Steele
The marine cryosphere is a complex system that has experienced some of
the most extreme environmental changes on Earth, such as declining sea
ice extent, warming surface ocean and air temperatures and ecosystem
shifts. These influence the global surface energy and moisture budgets,
atmospheric and oceanic circulation, and feedbacks. To predict future
changes in sea ice it is necessary to understand the complex and coupled
interactions between ice, ocean, atmosphere, and land. Improved
representation of coupled processes and feedbacks is expected to advance
predictive skill of polar weather and climate models, and linkages with
lower latitudes. Conveners solicit papers on observational, theoretical
and numerical investigations that advance a system level understanding
of processes that affect sea ice extent and thickness in the Arctic and
Southern Oceans by studying the interaction between ice and at least one
other component of the polar system (ocean, ecosystems, atmosphere,
land).

Dispersion, Aerosols, Halogens and Unusual Oxidants
Conveners: Steven S Brown, William R Simpson, and Joel A Thornton
Nearly 60% of the world's population lives north of the tropics,
accounting for 70% of anthropogenic CO^2, 65% of nitrogen oxide and 73%
of sulfur dioxide emissions, with peak emissions at mid latitudes.
During summertime, rapid oxidation converts primary emissions to
secondary pollutants, such as ozone and aerosols, near to source
regions. Slower chemical conversion rates in winter lead to wider
dispersion of primary pollutants and oxidation dominated by
heterogeneous or multiphase chemistry and longer-wavelength photolysis
reactions such as those of carbonyls and halogens. Acute impacts are
associated with strong temperature inversions that exacerbate primary
pollutant exposure and semi-volatile aerosol haze episodes, with snow
cover playing a potentially important role. This session invites
submissions from recent field, laboratory and modeling studies relevant
to mid- and high-latitude winter that advance the understanding of
seasonal and latitudinal impacts of anthropogenic pollutants at all
scales.
https://agu.confex.com/agu/fm15/preliminaryview.cgi/Session7972Session 8005: Utility and Quality of Reanalyses in the Polar Regions
Conveners: David H Bromwich and James A Renwick
Retrospective analyses (or reanalyses) are key tools for investigating
climate variability and change in the data sparse polar regions. They
combine observations with analysis estimates from a short-term model
forecast (background) and take into account uncertainties of the
observations and the background. Originally focused on the atmosphere
only, some reanalyses now focus solely on the ocean or the land surface,
while coupled atmosphere-ocean reanayses are starting to be produced.
There are many challenges to producing reliable reanalyses in the polar
regions. Contributions to assessing the current state of reanalyses in
the polar regions are solicited on the following: intercomparison of
reanalyses, both global and regional; polar-specific challenges
regarding observations, data assimilation, model physics, oceanic
boundary conditions, especially sea ice; reanalysis for the Southern
Ocean and Antarctica before the start of the satellite era; ensemble
approaches for background error, reanalysis uncertainty, and compositing
reanalyses; and reliability of trends and climatologies.
https://agu.confex.com/agu/fm15/preliminaryview.cgi/Session8005Session 8222: Geologic and Geodynamic Evolution of the Arctic Region
Conveners: Eric S Gottlieb, Richard O Lease, Ward Saltus, and Tim O'Brien
Over the last quarter century, scientific and entrepreneurial agendas
for the Arctic have expanded greatly as climate change, international
politics and technological innovations have diminished logistical
barriers and opened a modern frontier for scientific and resource
exploration. Despite years of study, much of the framework geologic
history of the Arctic Ocean and its surrounding landmasses is
insufficiently constrained by existing data and is thus controversial.
Elucidating the multiphase plate tectonic history of the oceanic and
surrounding continental realms through robust plate reconstructions and
regional tectonic syntheses is a fundamental challenge. We seek research
that addresses the challenging geology of the Arctic, especially
submissions that integrate understanding of (1) age, lithology,
structure, and/or paleo-(bio)geography of circum-Arctic lithosphere, (2)
tectonic and geodynamic processes of lithosphere generation and
modification, and (3) geologic and geophysical correlations across the
oceanic realm and into better-studied regions of Eurasia, Laurentia and
elsewhere.
https://agu.confex.com/agu/fm15/preliminaryview.cgi/Session8222Session 8330: Effects of Sea Ice on Arctic Biota
Conveners: Marc Macias-Fauria and Eric Post
The strong Arctic sea ice decrease in the last decades poses urgent
questions regarding its ecological effects. These trends occur before we
can fully understand many of the mechanisms that couple sea ice and
biological processes, largely hampering our ability to predict and
manage the consequences of this enormous environmental change. Valuable
short and patchy observations, traditional ecological knowledge,
remotely sensed data, and a wealth of proxy data--ranging from
sedimentary records to ancient DNA--constitute sources of information
researchers employ to study these mechanisms linking sea ice and Arctic
ecosystems at a range of spatial and temporal scales. This session will
provide a forum to discuss the latest findings in this field, covering
research in phenology, population dynamics, productivity, range
dynamics--including invasive species and local/total extinctions, and
long-term ecology inferred from phylogeography/molecular ecology and
palaeo-proxies, for both terrestrial and marine ecosystems.
https://agu.confex.com/agu/fm15/preliminaryview.cgi/Session8330Session 8846: Communication as a Driver of Landscape Change
Conveners: Sarah Trainor, Amanda Robertson, Alison York, and Kristin Timm
Existing complementary scholarship in sustainability science, science
communication, decision sciences, and climate adaptation emphasize the
importance of salience, credibility and legitimacy achieved through
iterative, two-way communication, trust-building, and
decision-application, leading to use-inspired science and the
co-production of knowledge. Investigations of landscape change in
complex social-ecological systems have identified physical, ecological,
and social drivers of change including parameters such as climate
change, hydrologic change, wildfire, invasive species, land-clearing,
policy, regulations and economic incentives. Building on this
foundation, this session explores if and how science communication is a
driver of landscape change and the ways in which it is analyzed. We
invite theoretical and empirical presentations that address issues such
as: How do methods of science communication impact land-use and resource
management decisions? How do boundary organizations influence land,
resource and policy decisions thereby influencing future pathways of
landscape change? How does the co-production of knowledge effect
subsequent investigations of landscape change?
