23-28 April 2017

Organizers of a session entitled "Nitrogen-transformation Processes in
Terrestrial and Aquatic Ecosystems" announce a call for abstract
submissions. This session, also identified as BG1.10, will be held
during the European Geosciences Union (EGU) General Assembly 2017, which
will convene 23-28 April 2017 in Vienna, Austria.

Abstract submission deadline: 11 January 2017.

Session description:
BG1.10 - Nitrogen-transformation processes in terrestrial and aquatic
ecosystems: advances in pathways-tracing, quantification and
process-based modelling.

Anthropogenic disturbance of the nitrogen (N) cycle has more than
doubled the amount of reactive N circulating in the biosphere. This
session seeks to improve our understanding on how various microbial
processes contribute to N cycling in terrestrial and aquatic ecosystems,
how global changes impact ecosystem N biogeochemistry and what feedbacks
from N cycling will be most important in influencing the climate. The
presentations will cover all aspects of ecosystem N cycling, especially
methodological advances in measuring and modelling of microbial
N-transformation processes such as denitrification, nitrification,
co-denitrification, nitrifier-denitrification, nitrate ammonification
(DNRA) or anerobic ammonia oxidation (ANAMMOX), as well as their
contributions to exchange of gaseous N species (N2, N2O emissions) under
field-like conditions. The session will also highlight innovative
isotopic, molecular and modelling methods on N cycling communities and
processes at various scales, interactions with other element cycles
(e.g., carbon, phosphorus), terrestrial-aquatic linkages, and feedbacks
to global change.

Cross Disciplinary Observations for an Integrated Understanding of
the Arctic System
EGU General Assembly, 2017
23-28 April 2017
Vienna, Austria

Organizers of a session entitled "Cross Disciplinary Observations for an
Integrated Understanding of the Arctic System" announce a call for
abstract submissions. This session, also identified as
IE1.2/CR6.11/AS4.23 will be held during the European Geosciences Union
(EGU) General Assembly 2017, which will convene 23-28 April 2017 in
Vienna, Austria.

Abstract submission deadline: 11 January 2017.

Session description:
IE1.2/CR6.11/AS4.23 - Cross Disciplinary Observations for an Integrated
Understanding of the Arctic System

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 and cross disciplinary
approach is needed. Ongoing international collaborations have increased
inter-comparability of long-term measurements. Two examples are for
atmospheric and cryospheric observations through the International
Arctic Systems for Observing the Atmosphere (IASOA) and the Global
Cryosphere Watch (GCW). The primary measurements made by the atmospheric
observatories are clouds, aerosols, radiation, chemistry, atmospheric
structure, fluxes and meteorology. The primary measurements made over
land by the cryospheric observatories are permafrost, soil temperatures,
ground ice, ice sheets, albedo, melt-freeze cycles, and a myriad of snow
properties. In most cases, the IASOA observatories are also GCW
observatories and atmospheric and cryosphere observations are
considerably strengthened by co-located measurements of the atmospheric
boundary layer, surface and sub-surface properties, which enable studies
of Arctic ice/ocean/land/atmosphere interactions and coupling. The IASOA
and GCW consortiums operate by promoting standardized measurement
practices and data acquisition, data accessibility, and coordination of
international science collaboratory working groups.

This session invites presentations on the following topics:

Analyses of observations in the Arctic, including process studies,
climatologies, and validation of reanalyses, prognostic models, and
satellite products, in particular those that utilize both atmospheric
and cryospheric observations and make regional comparisons;
Studies of processes using multiple sensors at a single observatory
that support process understanding of the Arctic
atmosphere-terrestrial-cryosphere-ocean system;
Studies that advance our understanding of the coupling processes
between the Arctic atmosphere and the cryosphere surface;
Reports from projects and network organizations working to improve
consistent observation practices, data accessibility and data
standardization in the Arctic region; and
Reports on status and capabilities of the individual observatories
that support both IASOA and GCW.

It is expected that presentations will be relevant to providing a
science foundation under the umbrella of SAON
(www.arcticobserving.org/), which is purposed "to support and strengthen
the development of multinational engagement for sustained and
coordinated pan-Arctic observing and data sharing systems that serve
societal needs, particularly related to environmental, social, economic
and cultural issues" as well as the IASC atmosphere
(iasc.info/working-groups/atmosphere) and cryosphere working groups
(iasc.info/working-groups/cryosphere).
