[CRYOLIST] AGU Fall Meeting session CO34: Reconstructing ice-sheet behavior on millennial timescales

Dear Cryolisters,

We would like to highlight the following cryosphere focussed session to be held at the AGU 2012 Fall meeting:

CO34: Reconstructing ice-sheet behavior on millennial timescales: Integrating high resolution geological data with model simulations

This session focuses on the comparison and integration of high-resolution numerical ice-sheet models and detailed terrestrial and marine geological data sets, to better resolve the geometry, volume and ice dynamical characteristics of the Earth's ice sheets. Such reconstructions provide critical benchmarks for ice sheet and climate models and reduce uncertainty in predictions of the response of modern ice sheets (and thus sea level) to climate change. An integrated Earth systems approach is critical to achieve this. It is only by combining high-resolution modelling with comprehensive, highly precise empirical paleo-ice sheet constraints that a full understanding of the mechanisms of past change can be determined, and predictions for the future made with greater confidence.

In light of ongoing developments in the fields of high-resolution ice sheet modelling, allied with the increasing precision of geophysical and geochronological tools with which to reconstruct ice sheet change, we invite submissions from groups and individuals addressing data / model comparisons of the Greenland and Antarctic ice sheets and paleo ice sheets during major climate transitions such as those recorded after the Last Glacial Maximum and earlier rapid climate transitions. We also encourage submissions from groups and individuals using theoretical and conceptual modelling studies that explicitly incorporate field data (e.g. conventional terrestrial and marine radiocarbon, multiple cosmogenic nuclides as well as marine geophysical data and glacio isostatic adjustment)

Confirmed keynote speakers include:

Dr Greg Balco: Berkeley Geochronology Centre

Prof. Paul Valdes: University of Bristol

Dr Paul Bierman: University of Vermont

AGU Abstract

Reconstructing the pattern, timing & rate of decay of Earth's contemporary and paleo ice sheets during periods of rapid climate change allows us to assess their sensitivity to environmental forcings beyond our short observational window. An integrated Earth systems approach is critical to achieve this & reduce uncertainty in predictions of the response of modern ice sheets (and thus sea level) to future change. This session focuses on the comparison and integration of high-resolution numerical ice-sheet models & detailed terrestrial and marine geological data sets, to better resolve the geometry, volume & ice dynamical characteristics of the Earth's ice sheets.

Look forward to see you at fall AGU meeting.

[CRYOLIST] AGU session: B069. Vulnerability of Permafrost Carbon to Climate Change

Dear Colleagues: Please consider submitting your AGU abstract to the following permafrost/carbon Biogeoscience session:

B069. Vulnerability of Permafrost Carbon to Climate Change
Permafrost zone soils contain 1670 Pg of carbon (C). Permafrost degradation can change ecosystem C storage by enhancing microbial activity and ecosystem respiration, but can also stimulate plant growth and increase C stored in vegetation and surface soil. This session invites papers that examine factors causing losses and gains in ecosystem C storage that relate to the question: What is the magnitude, timing and form of C release from permafrost zone ecosystems to the atmosphere in a changing climate? Papers may address any aspect of this topic from microbial communities to the global scale, using a range of measurements or modeling to detect and forecast permafrost thaw and the influence on the C cycle and future climate.

[CRYOLIST] AGU Cryosphere session C014 Geological Controls on Ice Dynamics

We would like to draw your attention to AGU Session C014 "Geological Controls on Ice Dynamics":

Geological conditions at the base of ice sheets exert control on ice dynamics through a variety of mechanisms including the distribution of geothermal heat flux, hydrological routing, basal friction and topographic control. Incorporation of these geological constraints into ice flow models is important for improving ice sheet mass balance and sea level rise predictions. Direct observations of subglacial geology are extremely scarce and geological conditions must be inferred from geophysical surveys from ground based, airborne and satellite campaigns. This session brings together geological, geophysical and glaciological observations and models from both poles that explore how geological conditions influence ice dynamics.

We hope to attract a mixture of observational and model-based studies to explore the influence of bed geology on the overlying ice, and we encourage you to consider submitting to the session.

Thanks

[CRYOLIST] Two FURTHER Cryosphere Sessions at AGU: climate change and Quaternary

Dear Colleagues (with apologies for cross-posting):

I have two exciting AGU sessions of cryospheric interest for your delectation, on Climate change and cryospheric systems (C004), and Quaternary and Holocene climate change in the Southern Hemisphere (GC037). Session descriptions are below.

Abstract deadline 8 August 2012 at 23:59ET/ 3:59+1 GMT, uploadable at: http://agu-fm12.abstractcentral.com/

If you have any questions, please email me (details in footer).

thanks, Jasper

C004: Climate change and cryospheric systems
Convenors: Jasper Knight (Witwatersrand), Neil Glasser (Aberystwyth), Stephan Harrison (Exeter)
Climate change exerts a first order control on the dynamics of cryospheric systems, including glaciers and ice sheets, sea ice and permafrost. These ice bodies have different sensitivities to climate forcing and leave different geological signatures from which their past dynamics can be inferred. This session will examine the role of climate forcing on cryospheric systems, with a focus on determining the interplay between climate and other factors as controls on cryospheric dynamics, and in identifying the climatic thresholds that determine their sensitivity to forcing. Contributions are invited on all types of cryospheric systems past and present, including geological, biological and dating evidence and modelling studies.

GC037: Quaternary and Holocene climate change in the Southern Hemisphere
Convenors: Jasper Knight (Witwatersrand), Stephen Tooth (Aberystwyth), Stefan Grab (Witwatersrand)
Quaternary and Holocene climate records in the Southern Hemisphere are sparse but cover many different terrestrial and marine environments in different climate zones. This session aims to integrate geological, biological and dating evidence from across the Southern Hemisphere in order to identify hemispheric-scale climate controls (including ocean circulation), teleconnections with rapid climate changes including Heinrich and Dansgaard-Oeschger events, and correlation between different records such as during the lateglacial. Contributions using geological, biological and dating evidence are invited from different terrestrial and marine environments across the Southern Hemisphere.

[CRYOLIST] Two Cryosphere Sessions at AGU Fall Meeting 2012 : Remote Sensing and Sea Level Rise

Dear colleagues,

please consider submitting your contribution to one of the following sessions at the 2012 AGU Fall meeting.

Sincerely,

Marco

C007: Cryospheric Contribution to Sea Level Rise: Current Estimates and Projections

We invite submissions concerning current estimates and projections of cryospheric contribution to sea-level rise. Many members of the cryosphere community are currently focusing on determining how current and projected temperature changes around the globe translate into ice loss and and sea-level rise. Specific themes include parameterization of ice-sheet processes affecting mass loss; surface mass balance projections from regional and global models; validation and initialization of models; fieldwork activities. Contributions concerning other aspects addressing the contribution of the components of the cryosphere to sea level rise are strongly encouraged and kindly invited.

C035: Remote Sensing of the Cryosphere

Remote sensing represents an efficient tool for monitoring and mapping the cryosphere over large areas where, otherwise, it would be difficult if not impossible. This session will bring together recent advances in remote sensing of components of the cryosphere such as frozen soil, snow, sea ice, ice sheets, etc. including results from recent field experiments, development and improvement of models, evaluation/development of techniques for the retrieval of geophysical parameters, data assimilation and data fusion. Contributions regarding remote sensing of cryosphere are kindly invited and strongly encouraged.

Re: [CRYOLIST] List changes

Todd,

I am sorry (for us, not you) that you are leaving academia. I am glad you are part of the GLIMS book, and that it is finally looming as reality for all of us. Thank you for your contributions to glaciology and remoter sensing. You will be missed. You have network of friends around the world, and you can count me among them. If you plan travels to Tucson for pleasure or work, and want to live out in the Sonoran Desert for that different sort of experience, we have a wonderful place and a spare bedroom.

CRYOLIST Community,

First, I want to thank you all for being part of CRYOLIST! It's been a great way for glaciologists to keep in contact over the last dozen years or so.

The "Conf" sub-list experiment that seems to have failed. Nearly every conf digest had only one email in it, so this method really didn't cut down on the traffic to the list as intended. Instead, it confounded subjects, made much more work for the me and the other moderators, especially Chris, and also made for some confused or frustrated list members.

We appreciate your help in trying out this experiment, but Chris and I have decided to end the conf list.

*** From now on, ALL emails, even conference-related ones, should be sent to CRYOLIST@CRYOLIST.ORG ***

On another note, I have left the world of academia. Whether this is permanent or temporary remains to be seen. I still intend to run CRYOLIST (along with Chris Marsh and our merry band of moderators) and keep up with the community and the science. I'm also still hoping to get a few publications out — especially some work that has been on the proverbial back burner for some time. But I do have a new position that utilizes my GIS and Geography skills as well as my programming skills, yet pays me a fair wage (finally).

So the chances of seeing me at a conference just dropped significantly, but I'll still be here behind the scenes at CRYOLIST.

All the best,

Todd

[CRYOLIST] Summit Greenland temperatures

For those of you interested in the reported air temperatures at Summit,
the NOAA data for 2012 is illustrated here relative to several previous
years of their JJA data (up to July 25th so far).
http://jcet.umbc.edu/2012/07/nasa-72412-press-release-green.html

The data shown will be updated periodically through the end of August.
And it bears repeating that the snow surface temperature (as tracked by
MODIS or the passive microwave sensors, see the NASA press release) can
differ by several degrees from the nominal 2 meter air temperature.

Cheers, Christopher

[CRYOLIST] the 2012 melt season over Greenland ice sheet simulated by MAR

Dear Colleagues,

If your are curious about the current melt season over the Greenland ice sheet and notably about the record of melt extent recently pointed out by the NASA, I have posted on my web site some results of the regional climate model MAR forced by the ECMWF operational reanalysis unitil the 22nd of July:

http://climato.be/melt-2012

MAR suggests that the 2012 seems to be again a record melt season with a time integrated SMB near the absolute minimum of 2010. As previous summers, this is again due to (negative) anomalies in NAO.

Enjoy your holiday after the IPCC deadline,

Xavier

Dear Colleagues,

We are inviting abstracts for the Fall 2012 AGU session we are hosting entitled C030: Polar Snow and Firn Processes.

Advanced technology has improved capabilities to monitor and model snow and firn changes. Interactions between the atmosphere and surface influence accumulation, firn metamorphism, densification, and chemistry and significantly alter microstructure and stratigraphy. This session will focus on field data, laboratory analyses, and modeling of polar snow and firn processes. We invite abstracts on measurement and modeling of these processes, including those which influence chemistry, photochemistry, metamorphism, and physical and radiative properties. Presentations on the application of new technologies such as terrestrial laser scanning, optical sensing of SSA, and CT scanning, in addition to the incorporation of these data into modeling efforts, are welcomed.

We have a great line up of invited presenters, and are looking forward to an interesting and informative session.

Abstracts are due August 8, 2012, which is just around the corner. Abstracts can be submitted at the following web address:

Dear Cryolisters,

**We'd like to take this opportunity to remind you of a new Cryosphere session (CO38) at this years AGU Fall Meeting, "Supraglacial and Englacial Hydrology".**

Session description: The need to better represent glacial hydrology within ice sheet models and provide inputs to subglacial hydrology models has resulted in a growth in research of the supraglacial and englacial systems. This includes surface meltwater pathways and storage, englacial system evolution at a range of time scales and its influence on meltwater transfer to the subglacial system, the role of hydrology on thermal and structural properties of ice, and implementation of supraglacial and englacial hydrology within glacier and ice sheet models. This session aims to bring together research reporting field investigations and modeling of these systems. We hope that this session will serve as a useful forum for exchange of ideas between field and modeling research groups.

Our session will include invited contributions from Professors Doug Benn and Andrew Fountain, and we are looking forward to an interesting and exciting range of talks and posters, so please consider this new session when you are submitting your abstracts in the coming days!

Best wishes and looking forward to seeing many of you at AGU.

Caroline Clason, Hari Rajaram and Thomas Phillips

Subject: AGU Session GC004 - Barrow, Alaska: Decades of Iconic Data
Sets as a Cornerstone of Arctic Observing
Message-ID: <500EECB3.5020002@gi.alaska.edu>
Content-Type: text/plain; charset="iso-8859-1"; Format="flowed"

Dear colleagues,

we wish to invite submissions to our AGU session entitled " GC004:
Barrow, Alaska: Decades of Iconic Data Sets as a Cornerstone of Arctic
Observing"

Barrow has served as a base for all aspects of Arctic research. Local,
traditional knowledge among the resident I?upiat extends back many
generations. Thus, Barrow is a potential flagship site for the U.S.
Interagency Arctic Observing Network (IAON) and international programs
in Alaska. This session focuses on Barrow region data sets of high
quality, long duration, and high scientific and stakeholder relevance.
Examples include climate stations, river and sea ice breakup dates,
plant community changes or permafrost borehole temperatures. The aims
are to showcase such iconic data and help create a framework for their
sustainment and application within IAON to address key questions about a
changing Arctic.

Our invited speakers are:
George Divoky (Friends of Cooper Island)
Craig George (North Slope Borough Department of Wildlife Management)
Steven Oberbauer (Florida International University)
Matt Shupe (NOAA / University of Colorado)

Regards,

Tom Heinrichs
Mark Ivey
Andy Mahoney
Craig Tweedie

[CRYOLIST] Conf Digest, Vol 22, Issue 1

[CRYOLIST] Postdoctoral positions at Hokkaido University, Sapporo

Dear colleagues:

Applications are invited for two postdoctoral positions at Hokkaido
University (HU) sponsored by the AXA Research Fund (ARF). The positions
are for the period

1 April 2013 - 30 March 2015 (2 years).

The application process is two-staged (pre-selection by HU, final
selection by ARF), and the deadline for the pre-selection round is

24 August 2012.

I'd be happy to act as host supervisor for modelling projects related to
the prediction of ice sheet contribution to future sea level rise,
preferably with the ice sheet models SICOPOLIS (sicopolis.greveweb.net)
or Elmer/Ice (elmerice.elmerfem.org) currently operated at the Institute
of Low Temperature Science. This would qualify under the field
"geosciences" and the risk category "environmental risks". For more
details, please see the online posting of HU's Creative Research
Institution at

http://www.cris.hokudai.ac.jp/cris/en/news/info/493.html

Please contact me as soon as possible if you are interested.

Best regards,

Ralf Greve
