[CRYOLIST] AGU Fall Meeting Session on lateral eddy mixing and diffusivities: estimation from observations and model parameterizations

Dear Colleagues,

For those of you who are interested in lateral eddy mixing and stirring in polar oceans and under the sea ice and shelves, as well as the representation of these processes in models, please consider submitting an abstract to the AGU 2018 Fall Meeting session "Beyond constant eddy diffusivities: Estimation, implementation, impacts, and new approaches to the parametrization of lateral mixing in ocean models".

The AGU Fall Meeting takes place in Washington, D.C., on December 10-14, 2018 and it serves as the advent of AGU's Centennial year. In this spirit, and with our session collecting, linking and reviewing different approaches, we are aiming to open for a new area in research concerning lateral eddy mixing. The session features invited authors: Dr. Sylvia T. Cole, Woods Hole Oceanographic Institution, and Prof. Trevor McDougall, University of New South Wales. The deadline for abstract submission is August 1, 2018, 11:59 PM EDT.

Session title: "Beyond constant eddy diffusivities: Estimation, implementation, impacts, and new approaches to the parametrization of lateral mixing in ocean models"

Session ID: 45421 (OS005)

Conveners:  Inga Monika Koszalka, GEOMAR Helmholtz Centre for Ocean Research Kiel, Kiel, Germany, K. Shafer Smith, New York University, New York, NY, United States, Anand Gnanadesikan, Johns Hopkins Univ-EPS, Baltimore, MD, United States and Baylor Fox-Kemper, Brown University, Providence, RI, United States

Session Description: In ocean climate models, the lateral transport of tracers due to unresolved turbulent flows must be parametrized. The most common approach mimics molecular diffusion, or anisotropic diffusion to represent stirring along isopycnals (Redi coefficient), and represents unresolved eddy-induced advection by slumping isopycnals at a rate proportional to their slopes (Gent-McWilliams coefficient). Constraining the values of these parameters has been a goal of the modeling and observational communities for decades. This session addresses (1) advances in estimation of mixing and tracer variance production by eddies from observations and high resolution models, (2) theoretical approaches to constrain the parameters, including inverse methods, (3) implementation in ocean models, (4) impacts of parameterizations on modeled tracers and/or climate variability, and (5) novel approaches. The focus of the session is on methods and quantities relevant to model parameterizations specifically, as opposed to diagnosis of turbulent structures for other reasons.

Invited authors: Dr. Sylvia T. Cole, Woods Hole Oceanographic Institution, and Prof. Trevor McDougall, University of New South Wales.

Dear Colleagues,

We would like to invite you to submit an abstract to the 2018 Fall AGU meeting session on

"Sea ice-ocean-atmosphere interactions in the "New" Arctic and Southern Oceans"

 

Cryosphere Session C037: https://agu.confex.com/agu/fm18/prelim.cgi/Session/43265

 

The session description is:
Record low sea-ice extent is currently observed in both the Arctic and Antarctic, variability that is unprecedented in the satellite record. Warming ocean temperatures, changes in atmospheric circulation patterns, and frequency of synoptic systems contribute to this variability. 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). This session will feature 5-minute discussion periods after talks to facilitate dialog on overlapping issues.

 

Cross-Listed: Global Environmental Change, Atmospheric Sciences, Ocean Sciences

 

The AGU Fall Meeting will be held 10-14 December 2018 in Washington DC this year. 
The meeting website is: https://fallmeeting.agu.org/2018/
Abstract submissions are due by August 1 11:59 EDT.

We look forward to your contributions!

[CRYOLIST] EGU2019 - propose a CR-session

Dear colleague,

The next EGU General Assembly 2019 (EGU2019) will be held at the Austria Center Vienna (ACV) from 07 to 12 April 2019.

We hereby invite you, from now until 06 Sep 2018, to take an active part in organizing the scientific programme of the conference. You can do this at: https://meetingorganizer.copernicus.org/EGU2019/provisionalprogramme

Please use this opportunity to suggest sessions with conveners and description.

NEW IN 2019

a) For the first time, the skeleton programme consists only of the programme groups and their sub-programme groups. The programme groups do not show sessions from last year. This means that all session proposals need to be submitted, also those on classic topics in the community.

b) The deadline for suggesting Union Symposia and Great Debates is 15 August 2018. Please see the guidelines (https://www.egu2019.eu/guidelines/us_and_gdb_guidelines.html) for more information.

POINTS TO BE CONSIDERED WHEN SUGGESTING A SESSION, SHORT COURSE, OR TOWNHALL MEETING

1) Session conveners
We strongly encourage convener teams to reflect (i) multiple countries and institutes, (ii) different career stages, and especially include early career scientists, and (iii) gender diversity. We ask for a minimum of two active conveners (1 convener and 1 co-convener) with a maximum of five conveners (1 convener and 4 co-conveners) per session.  A new guideline for 2019 is a maximum of three (co-)convenerships total of which one as lead convener. We would like to point to the presentation rules for conveners (https://egu2019.eu/guidelines/convener_guidelines.html#solicited). Please check with all conveners that they agree to take part in the proposed session. Please see the convener guidelines at: https://www.egu2019.eu/guidelines/convener_guidelines.html

2) Session Programme Group (PG)
When making suggestions, explore the programme groups (https://meetingorganizer.copernicus.org/EGU2019/provisionalprogramme) and place your proposal into the PG that is most closely aligned with the proposed session's subject area. Please avoid submitting session proposals that are similar to sessions already suggested. In such a case, it is possible to suggest modifications to an earlier session proposal. If the subject area of your proposal is strongly aligned with two or more PGs, co-organization is possible and encouraged between PGs. Only put your session proposal into ONE PG. You will be able to indicate PGs that you believe should be approached for co-organization.

3) Inter- and Transdisciplinary Sessions (ITS)
EGU introduced the programme group Interdisciplinary Events (IE) in 2016 which is now renamed to Inter- and Transdisciplinary Sessions (ITS). ITS looks for links between disciplines in a coordinated and coherent effort, trying to create new approaches that would not be possible if handled separately. ITS highlights new themes each year and will also build themes from proposed sessions. If you plan to propose an Inter- and Transdisciplinary Session, please submit your proposal in programme group ITS and indicate other relevant programme groups for co-organization. For ITS sessions we kindly ask you to identify one other programme group that will become the scientific leader of the event. Accepted ITS sessions will be part of the session programme of the scientific leader in addition to the ITS programme. Please see the guidelines for more information at: https://egu2019.eu/guidelines/its_guidelines.html

4) Townhall and splinter meetings
From now until 17 Jan 2019 you can apply for townhall meetings. Townhall meetings offer an active discussion platform that is open to all interested participants to inform them of new opportunities and initiatives. All townhall meetings will be scheduled from 19:00 to 20:00. Splinter meeting rooms can be booked for smaller, targeted discussion groups. Splinter meeting booking is open from 15 Oct 2018 to 1 Mar 2019.

5) Session programme building
The EGU2019 Programme Committee will take into account all suggested sessions and use these to compile the final session programme as the basis for the call-for-abstracts. Conveners of approved sessions will be asked to actively promote their sessions and the public will be invited to submit their abstracts. This will be announced by a separate email.

Session ID: 49032

Session Title: NS001: Advances and Revelations from Geophysical Exploration and Observation in the Cryosphere

Session Description: High-elevation and high-latitude regions of our planet are responding rapidly to a changing climate, causing substantial impacts to Earth processes at all spatiotemporal scales. Many of the most pressing cryospheric research questions involve processes and/or structures in the interior or at the base of frozen Earth materials, and are therefore difficult to study directly. Advancements in instrumentation and processing approaches are rapidly improving our abilities to measure and understand glacier ice, sea ice, snow, and permafrost processes. In this session, we seek submissions related to a broad range of ground and airborne geophysical methods (e.g. ground penetrating radar, electrical resistivity, nuclear magnetic resonance, electromagnetic, seismic, gravity etc.) applied to solve cryospheric problems. Studies aimed at the characterization, detection, and/or monitoring of cold region environments using geophysical field and/or modeling methodologies are welcome. Multidisciplinary topics, innovative approaches, and research combining geophysical methods with geomodels are particularly encouraged.

 

Abstract submission information: https://agu.confex.com/agu/fm18/prelim.cgi/Session/49032

For the first time, the AGU Fall Meeting will be held in Washington, D.C., where we will mark the launch AGU's Centennial.  A wide variety of events are being planned that will take advantage of this special location that will showcase our science to the U.S. and international policy community, students, and public); leverage the local scientific community, including events with the Smithsonian, National Academies, and others; and, offer field trips to view the local geology and research institutes. The Fall Meeting will also offer more workshops as well as new Tutorial sessions to help students and researchers learn about new approaches and techniques and introduce exciting science in other disciplines.

Additional information, including everything you need to know about abstract submission is here: https://fallmeeting.agu.org/2018/.  Please consider submitting an abstract and/or attending to help show "What Science Stands For" and to join in an exciting and informative start to AGU's Centennial. Submissions received by the early deadline of 25 July have a chance to win a $100 US gift card.

[CRYOLIST] Research Scientist in Lagrangian Iceberg Modelling

Dear All,

The Atmospheric and Oceanic Sciences Program at Princeton University, in association with NOAA's Geophysical Fluid Dynamics Laboratory (GFDL), seeks a postdoctoral research associate to experiment with, and further develop, a Lagrangian model of tabular icebergs for use as a component of an earth system model.

This work will involve developing modeling representations of iceberg formation, evolution and breakup, by using a mix of discrete element modelling and conceptual parameterizations of unresolved processes in a prognostic iceberg model. The project aims to enable simulation of tabular icebergs in realistic representations of the global ocean and to use such simulations to study both historical events and look at future projections.

The ideal candidate has a strong background in one or more areas among material science, soft-matter science (granular materials), physical oceanography, numerical methods, sea-ice dynamics and geophysical fluid dynamics. Experience with smoothed particle hydrodynamics solvers, the discrete element method, and or large general circulation models will be advantageous in this research.

Candidates must have a Ph.D. in either applied mathematics, physics, cryosphere, or a related field by the time their appointment starts.  Initial appointment is for one year with the possibility of renewal subject to satisfactory performance and available funding.

Complete applications, including a CV, a statement of research interests, and contact information of 3 references should be submitted by July 6th, 2018 for full consideration.  Applicants must apply online to https://www.princeton.edu/acad-positions/position/7021. 

For more information about the research project and application process, please contact Alistair Adcroft (aadcroft@princeton.edu) or Olga Sergienko (osergien@princeton.edu). This position is subject to the University's background check policy.

Princeton University is an Equal Opportunity/Affirmative Action employer and all qualified applicants will receive consideration for employment without regard to age, race, color, religion, sex, sexual orientation, gender identity or expression, national origin, disability status, protected veteran status, or any other characteristic protected by law.

[CRYOLIST] PhD position in ice core/radionuclide studies at Lund University

A fully-funded PhD position in ice core/radionuclide studies at Lund University:

Long-term changes in solar activity inferred from ice core cosmogenic radionuclide records

The project " Paleosun – the paleoperspective on the mechanisms behind the sun-climate link" aims to improve solar activity reconstructions using different geologic archives and to improve sun-climate studies with radionuclide and climate proxy measurements from the same archive. These studies will also enable us to obtain very accurate and precise time scales that are crucial for reliable paleoclimate studies. 

Cosmogenic radionuclide records reflect a combination of production and deposition processes (atmospheric circulation (10Be) and carbon cycle (14C)). Presently the different radionuclide records show disagreements regarding their long-term (millennial time scales) changes for reasons that are not understood. This leads to major uncertainties in reconstructions of past changes in solar activity.

This project will be based on 10Be measurements in ice samples from Antarctica covering the last 20000 years. The new record will be analysed in combination with existing 10Be data from ice cores and tree-ring 14C data. It will involve assessment of climate and geomagnetic field influences on radionuclide records and carbon cycle influences on 14C.

[CRYOLIST] AGU 2018, S008: Environmental Seismology session

Dear Colleagues,

We are excited to invite abstract submissions to the first session on environmental seismology (S008) at AGU this year. Please consider contributing to this interdisciplinary session!

 

(S008) Environmental seismology: using geophysical tools for Earth surface processes research
Recent work has highlighted the generation of elastic waves by processes at or near the Earth's surface, and seismic techniques are being utilized to examine an increasingly diverse range of processes, hazards and materials. Seismic detection, monitoring and characterization methods can provide continuous, real-time data with high temporal resolution and broad spatial coverage of multiple sources and inaccessible environments. Areas of recent advancement include: mass movement (landslides, rockfalls, debris flows, lahars); hydrologic (groundwater, open water waves/tides, outburst floods, turbulence, sediment transport), cryospheric (avalanches, icequakes, calving, ice fracture/deformation, glacial hydrology/sliding), atmospheric and oceanic (microseisms, extreme weather, gravity waves) phenomena; use of large-N arrays; 4-d imaging of substrate, material, and structural attributes; and anthropogenic sources.

This session connects scientists applying theoretical, field-based and experimental seismic methods to Earth surface and near-surface dynamics. We invite contributions from geomorphology, cryospheric sciences, seismology, hazards, volcanology, soil sciences, rock mechanics, hydrology, and related fields.

[CRYOLIST] AGU Session H022: Applications in Snow Hydrology: Linking Seasonal Snow to Natural Processes and Society

Dear Colleagues,

Greetings!

Please consider submitting an AGU abstract to the following session focusing on snow hydrology applications and the connections between snow and broader natural and societal systems.

Session ID: 54299 

Session Title: H022. Applications in Snow Hydrology: Linking Seasonal Snow to Natural Processes and Society 

Section/Focus Group: Hydrology

Session Link: https://agu.confex.com/agu/fm18/prelim.cgi/Session/54299

Confirmed Invited Speakers: 

Dr. Jessica Lundquist, University of Washington

Dr. Anne Nolin, Oregon State University / University of Nevada, Reno

Session Description:

Snow plays a critical role in the water and energy cycles; however, in-depth understanding of its role in natural and human systems has been limited by a lack of reliable observations. Advances in field measurements, remote sensing, and modeling capabilities are critical for linking snowpack information to broader processes and understanding how climate dynamics impact the historical/future water supply and infrastructure. This session invites submissions focusing on innovative approaches linking snow to broader fields that address important questions such as: How do extreme events and variability in snow affect the hydrologic cycle, environment, energy sector, resource management, infrastructure, etc.? What recent advancements in snow hydrology better inform these fields? How can these advances better characterize runoff and its linkage to other processes in cold regions? We welcome submissions connecting snow to water and energy cycles across various spatiotemporal scales pertaining to hazards, streamflow forecasting, hydropower, ecology, agriculture, etc.

Thanks again for your consideration. We look forward receiving your abstract and seeing you in DC!

Best regards,

[CRYOLIST] AGU Session C009 on Atmospheric Moisture in the Arctic Climate System

Hello hello. We invite you to consider submitting your abstract to our
session on "Atmospheric moisture in the Arctic climate system" for the
AGU 2018 Fall Meeting.

By referring to atmospheric moisture, we aim to focus on several
overlapping topics in recent Arctic studies that include the role of
evolving cloud properties and water vapor on observed warming trends,
precipitation processes and their effects on sea ice cover, and
uncertainty in modeling and observational records of atmospheric
moisture and precipitation.

We hope to see you in DC, thanks!
Richard Cullather, Linette Boisvert, Melinda Webster,
& Alek Petty

Session Title: C009. Atmospheric moisture in the Arctic climate system
Section/Focus Group: Cryosphere
Session Description:
The session aim is to facilitate cross-disciplinary discussion among
those studying Arctic cloud and water vapor properties, precipitation
characteristics, and their role in evolving Arctic surface conditions.
In the Arctic, recent attention has focused on atmospheric moisture as a
potential catalyst for observed warm surface temperatures in recent
winters, and in the reduction of sea ice cover throughout the year.
Evolving snow and rainfall characteristics have also been the subject of
attention for understanding Arctic climate variability. A quantitative
understanding of snowfall is also important for remote sensing of sea
ice volume via satellite altimetry methods, which calls attention to
dissimilar Arctic accumulation estimates among various models. These
topics are inherently linked through the treatment of atmospheric
moisture, its application in remote sensing methods and in model
representations. This session invites papers that address the analysis,
diagnosis, and modeling of Arctic clouds, water vapor, and precipitation
processes using innovative approaches.

[CRYOLIST] Firn Water Retention Intercomparison Project (RetMIP)

Firn Water Retention Intercomparison Project (RetMIP)

                                                                     

To perform an intercomparison of meltwater retention, refreezing and runoff in different SMB and firn models without the complicating factors of different weather forcing at the surface, grids and glacier masks, we propose a coordinated experiment, where different firn models are driven by the same surface inputs of mass and energy.

 

Two streams of experiments are planned, and participants may take part in one or both of these:

-          A set of 5 pointwise runs driven by observed surface fluxes, initialized with and benchmarked against observed subsurface profiles of temperature and density.

-          An all-Greenland run on a common 11 km grid driven by surface fluxes from a regional climate model. Initialization is performed through a spinup.

 

Please visit http://retain.geus.dk/index.php/retmip/. Here we describe for both of these experiments, the site/domain, the input data provided, the initialization procedure for the subsurface modeling, the requested output and the file formats.

 

The distributed input data and the collected output data will be made available to all participants. We aim to make a journal publication out of the results with all participants as co-authors.

 

Output from your experiments should be submitted by Sep 1 2018. If you are unable to make this deadline, let us know and we can try and work something out.

 

Please indicate as soon as possible if you wish to participate, and please let us know which of the experiments you want to take part in (pla@dmi.dk).

 

All the best,

Peter Langen, Baptiste Vandecrux and the rest of the RETAIN team

 

 

 

[CRYOLIST] Cryo Connect - cryosphere science outreach gateway

Dear colleagues,

We invite you to join Cryo Connect, a non-profit gateway facilitating information exchange between cryo scientists, journalists, policy makers and everyone else with a professional interest in the cryosphere.

We aim to provide equal exposure to all scientist groups, including those that are currently underrepresented in the media and beyond, such as aspiring young researchers, women, and scientists from non-native English speaking countries. Scientists can sign up by listing their areas of expertise and contact information. Information seekers that contact Cryo Connect with specific questions will then receive a shortlist of those scientists that can provide answers.

Additionally, Cryo Connect provides a platform to push your science news to larger audiences, much like sending out your own personal press releases (however short they may be), for instance by tweeting @CryoConnect.

Like this CryoList - Cryo Connect is and always will be free and simple. You will not be spammed, will not be obliged to act on anything, and can unlist anytime. A team of scientists runs Cryo Connect and safeguards your best interests.

For the journalists and other information seekers among you: please also visit our website!

Our partners: AGU, APECS, ICIMOD, IGS, IMAU, Isaaffik, WSL.

All the best,

Liam Colgan, Inka Koch, Faezeh Nick and Dirk van As
