  1. Arctic Ocean and Cryosphere in Rapid Transition
    Session: CR1.7/OS1.26

The Arctic is currently undergoing unprecedented climate and
environmental change at a pace that exceeds the global average by far.
The persistent mismatch between observed and projected patterns of
change makes planning and mitigation activities in the Arctic
challenging. Therefore, knowledge of the present and past status of the
Arctic Ocean and its adjacent coasts is urgently needed to make robust
projections of future conditions throughout the Arctic region.

The Arctic in Rapid Transition (ART, http://www.iarc.uaf.edu/en/ART)
network aims at better understanding and projecting rapid changes in the
Arctic. ART fosters multi-disciplinary and international research in the
Arctic with a focus on integrating spatial and temporal scales in the
marine realm and to adjacent Arctic systems.

Organizers invite contributions with a strong relation to the Arctic
Ocean and cryosphere under the following topics and beyond:

  • Arctic sea ice dynamics and oceanography;
  • Arctic land-ocean interactions including coastal permafrost dynamics;
  • Arctic ecosystems and biodiversity;
  • Arctic palaeoenvironmental archives including proxy development and calibration;
  • Arctic law, shipping, and exploration.

Studies of a multi-disciplinary nature linking the topics above and
studies from early career researchers are especially encouraged for
submission.

  1. Changes in the Arctic Ocean and Sea Ice System: Observations, Models,
    and Perspectives
    Session: IE4.3/OS1.2

The past decades of observations have shown sustained changes in the
Arctic Ocean and the Arctic sea ice cover. Since the beginning of
satellite observations in 1979, the Arctic sea ice extent has declined
throughout all seasons with the largest reduction occurring in summer.
Furthermore, the Arctic sea ice cover is now thinner, weaker, and drifts
faster. The ocean shows an increase in the Arctic freshwater storage and
warmer inflows from the Atlantic and Pacific Oceans. Coastal runoff from
Siberia and Greenland has also increased. As the global surface
temperature rises, the Arctic Ocean is speculated to become seasonally
ice-free in the 21st century, which prompts us to revisit our
perceptions of the Arctic system as a whole. What could the Arctic look
like in the future? How are the present changes in the Arctic going to
affect the lower latitudes? What aspects of the changing Arctic should
future observations and modeling programs address? The session invites
observation- and modeling-based submissions on past, present, and future
states of the Arctic; on the mutual interaction between ocean,
atmosphere, and sea ice; and links to global processes. The session
promotes results from current Arctic programs and encourages discussions
on future plans for Arctic Ocean modeling and measurement strategies.

  1. Reconstructing Past Hydroclimate Change in the Arctic
    Session: CL1.14/HS11.3

Future climate change in the Arctic is expected to involve increased
surface temperatures as well as changes in the amount and seasonality of
precipitation. Many terrestrial proxy records from the Arctic have been
used to infer past temperature but fewer have been used to reconstruct
hydroclimate. This is despite the fact that hydroclimatological changes
are an extremely important aspect of arctic climate variability and are
coupled to other aspects of the Arctic system, such as sea ice extent
and modes of atmospheric circulation. This session will bring together
researchers working to reconstruct hydroclimate across the Arctic on a
variety of timescales. Organizers welcome contributions from researchers
generating proxy records, synthesizing existing datasets, and working to
model impacts of hydroclimate changes. The session will highlight the
current state of knowledge, as well as data gaps, and identify
challenges and opportunities in assessing past hydroclimate variability
across the Arctic.

  1. Boundary Layers in High Latitudes: Physical and Chemical Exchange
    Processes Over Ocean-Ice-Snow-Land Surfaces
    Session: AS2.4/CR6.5/OS5.4/SSS9.22

Given the rapid changes in the Polar Regions, this session addresses key
physical and chemical processes, especially in the boundary layer, over
the Arctic and Antarctic whose understanding is needed to improve
predictability of future changes in the Polar Regions. These processes
include surface exchange of heat, momentum, moisture, and chemical
constituents over increasingly complex ocean-ice-snow-land surfaces.
Also of importance is dynamical connection of Polar Regions to the
mid-latitudes for their supply of heat, moisture, and various chemical
species. Of increasing interest is the role of extremes in the
atmospheric circulation, particularly meridional transport events that
can disturb the physical and chemical state of the high latitudes (that
may be associated with rapid sea ice reduction, melting of the ice
sheets, and marine physical and ecosystem changes, etc.).

This session is intended to provide an interdisciplinary forum to bring
together researchers working in the areas of high-latitude weather and
climate, boundary layer exchange processes, chemistry, and oceanography.
Organizers invite contributions in the following areas:

  1. Observations and research that explore physical and chemical exchange
    processes over ocean-ice-snow-land surfaces in the polar latitudes
    ranging from molecular to regional scales.
  2. Results from high-elevation sites where similar exchange processes
    over snow and ice are important are also welcome.
  3. Results from field programs and observatories, insights from
    laboratory studies, and advances in modeling including parameterization
    of the boundary layer and reanalysis.
  4. Advances in observing technology.
  5. External controls on the boundary layer such as clouds, aerosols,
    radiation, and transport processes.
  6. The role of boundary layers in polar climate change and implications
    of climate change for surface exchange processes, especially in the
    context of reduced Arctic sea ice and physical and chemical changes
    associated with an increasing fraction of first year ice.

  1. Regionally Integrated Perspectives on Arctic Processes From the
    International Arctic Systems for Observing the Atmosphere (IASOA)
    Session: IE4.4/AS4.2

To understand not just how, but why, the Arctic system is changing, and
to better serve the needs of stakeholders in the changing Arctic
environment, an integrated spatial-temporal approach is needed. To this
end, the International Arctic Systems for Observing the Atmosphere
(IASOA, http://www.iasoa.org) was developed to facilitate aggregating
observational studies from stations (Alert, Eureka, Villum, Summit,
Ny-Alesund, Pallas, Sodankyla, Tiksi, Cherskii, Barrow, Oliktok) in the
pan-Arctic region. The primary measurements made by the observatories
are atmospheric: clouds, aerosols, radiation, chemistry, atmospheric
structure and dynamics, and meteorology. These observations are
considerably strengthened by co-located measurements of surface and
sub-surface properties and adjacent Arctic Ocean measurements that allow
studies of ice/ocean/land-atmosphere interactions and coupling. The
IASOA consortium operates by promoting standardized measurement
practices and data acquisition, data accessibility, and coordination of
international science collaboratory working groups. IASOA is currently
expanding into evaluation of observatory-based service products that can
support human health, transportation, and energy development. Organizers
invite contributions in the following areas that use data from the IASOA
observatories:

  1. Analyses of observations from two or more IASOA locations, including
    process studies, climatologies, and validation of reanalyses, prognostic
    models, and satellite products.
  2. Detailed studies of processes using multiple sensors at a single
    observatory that support process understanding of the Arctic
    atmosphere-terrestrial-cryosphere-ocean system.
  3. Analyses of observations from a single observatory that provide a
    template for a more pan-Arctic synthesis studies.
  4. Reports from projects and network organizations working to improve
    data accessibility and data standardization in the Arctic region.
  5. Reports on status and capabilities of the individual IASOA and
    potential IASOA observatories.
  6. Papers defining requirements of users needing information that can
    only be provided with Arctic atmospheric observational networks (for
    instance, experimental designs for the Year of Polar Prediction).

Contributions need not be from researchers actively engaged with IASOA.
Although IASOA is an open consortium, recent publications indicate that
a pan-Arctic and system approach to understanding the Arctic environment
is being independently taken throughout the research community.

  1. Polar Continental Margins and Fjords-Climate, Oceanography,
    Tectonics and Geohazards
    Session: CL1.08/BG4.12/CR6.7/OS2.9

During the last decade significant advances in our understanding of the
development of polar continental margins during the Cenozoic have been
made. These include more detailed reconstructions of the climatic,
oceanographic, and tectonic evolution of high northern and southern
latitudes over various time scales, as well as reconstructions of past
ice-sheet dynamics and studies of marine geohazards. Results have been
obtained from conventional 2D and high-resolution 2D and 3D seismic
surveying, as well as from short sediment cores and longer drill cores
(e.g. IODP, MeBo).

Fjords are regarded as "small oceans" that incise high latitude
coastlines and link continental margins with the interiors of
landmasses. Fjord settings allow us to study a variety of geological
processes similar to those that have occurred on glaciated continental
margins, but typically at smaller scales. The contribution of several
sediment sources (e.g. glacial, fluvioglacial, fluvial, biological) to
fjord basins along with relatively high sedimentation rates also
provides the potential for high-resolution palaeoclimatic and
palaeooceanographic records on decadal to centennial timescales.

The aim of this multi-disciplinary session is to follow on from the
success of previous years by bringing together researchers working on
northern and southern high-latitude continental margins and fjords,
investigating the dynamics of past ice sheets, climate, tectonics,
sedimentary processes, physical oceanography, and palaeo-biology/ecology.
