Greenland Ice Loss and Response to Climate Forcings: Past,
Present, and Future
Disciplinary Sessions: CR3.5/CL4.5/OS1.16

Organizers of session CR3.5/CL4.5/OS1.16, "Greenland Ice Loss and
Response to Climate Forcings: Past, Present, and Future" announce a call
for abstracts. The session will be convened at the European Geociences
Union (EGU) General Assembly, 12-17 April 2015 in Vienna, Austria.

Greenland Ice Sheet mass loss accounts, at present, for one quarter of
global sea-level rise. The majority of the mass loss is concentrated at
the ice sheet margin due to the acceleration and thinning of outlet
glaciers. Oceanic and atmospheric warming have been suggested as the
dominant trigger of such changes yet the mechanisms controlling the ice
response to external forcing (i.e. oceanic, atmospheric) and internal
dynamics (i.e. subglacial hydrology, basal topography) are not well
constrained. Recent advances in observation and modeling have
illuminated surface changes and important processes at the bedrock,
atmosphere, and ocean interfaces. Paleoclimate data provides context for
recent climate changes and glacial responses, while ice sheet modeling
helps to identify the underlying dynamics. This session brings together
studies related to Greenland dynamics from oceanography, glaciology and
paleoclimatology to examine the complementarity of ideas and approaches
across scientific disciplines.

Organizers welcome contributions from modeling and theoretical studies,
modern and historical data, that provide insights into Greenland
response to climate forcing in the past, present and future. Topics may
include, but are not limited to:

- Ice-ocean interaction 
- Fjord circulation 
- Calving processes 
- Ice sheet modeling
- Bedrock and offshore bathymetry mapping
- Subglacial hydrology dynamics
- Paleoclimate modeling
- Records of past ice sheet extent

The abstract submission deadline for this and all other sessions is
Wednesday, 7 January 2015. To submit an abstract, please follow the
instructions at:

Polar Continental Margins and Fjords - Climate, Oceanography,
Tectonics and Geohazards
Disciplinary Sessions: CL1.7/TS5.6

Organizers of session CL1.7/TS5.6, "Polar Continental Margins and Fjords
- Climate, Oceanography, Tectonics and Geohazards" announce a call for
abstracts. The session will be convened at the European Geociences Union
(EGU) General Assembly, 12-17 April 2015 in Vienna, Austria.

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 paleoclimatic and
paleooceanographic records on decadal to centennial timescales.

The aim of this multi-disciplinary session is to follow from the
successes 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
- Paleo-biology/ecology

Boundary Layers in High Latitudes: Exploring Physics and Chemistry
across Scales
Disciplinary Session: AS2.3

Organizers of session AS2.3, "Boundary Layers in High Latitudes:
Exploring Physics and Chemistry across Scales" announce a call for
abstracts. The session will be convened at the European Geociences Union
(EGU) General Assembly, 12-17 April 2015 in Vienna, Austria.

Advancing boundary layer physics and chemistry over snow, ice, and water
in the high latitudes requires a scientific focus from the molecular
scale in snow, ice and water (and ancillary exchanges with the
atmosphere) to global scales responsible for long range transport and
the weather processes that control exchanges through the boundary layer.

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

- Studies that connect across scales to better understand the
boundary layer in the Arctic and Antarctic;
- Results from field programs and observatories, insights from
laboratory studies, and advances in modeling and reanalysis;
- Advances in observing technology;
- Surface processes involving snow, sea-ice, water, land/atmosphere
chemical exchange;
- External controls on the boundary layer such as clouds and
transport processes; and
- 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.

Given the interdisciplinary nature of this session, the organizers
encourage all presentations to start by briefly explaining how their
work relates to the broader context. In past years organizers have
requested a schedule where poster sessions follow oral sessions to allow
for oral poster introductions. For those who indicate a no preference
request for the presentation style, organizers encourage a Part II
poster supplement to allow for further discussion. Organizers encourage
young scientist/student presentations by reserving several oral units
per session for such papers.
