[CRYOLIST] The IcePod with Thomas Jung

Dear Colleagues, 

In the second bonus episode of the IcePod on the Targeted Observing Periods, we speak with Thomas Jung, captain and structured mind behind YOPP and PPP.

Here is the second episode on the YOPP Targeted Observing Periods, or TOPs. This time, we speak to Thomas Jung, head of the section Climate Dynamics at the German Alfred Wegener Institute and professor for Physics of the Climate System at the University of Bremen. Even more important, as the chair of the Polar Prediction Project's Steering Group, he is the captain and structured mind behind YOPP and PPP.

His ability to chair a meeting even with fever from his bed not only provides him with all the skills needed to steer the Polar Prediction Project during a pandemic, but has been the ultimate test of his leadership skills. Keeping a healthy balance between management and science is probably his secret to success, in addition to creating extensive but ultrapractical mind maps and building an international network across the academic community and forecasting experts.

Thomas has also been the winner of our YOPP TOP Twitter challenge. How did he overcome the jumpiness of forecast? Here, he unveils his secret: Well, it's just like planning your next barbecue weekend (something we all look forward to during this COVID-19 summer).

Take your time between an ice cream and a cold drink and listen to this episode for a look behind the scenes of YOPP, how the project came to life and how it still surprises its master of mind maps and virtual meetings.

[CRYOLIST] AGU 2020 session call for abstracts, thanks much!

Conveners of the following session at AGU 2020 invite abstract submissions:

Sea ice change and variability: Implications for the biophysical climate systems of the Arctic, Antarctic, and beyond
Conveners: Michael Steele, Laura Castro de la Guardia, Amy Solomon, and Marilyn N. Raphael

Seasonal sea ice coverage is changing rapidly in recent years, most notably in the Arctic but more recently in the Antarctic as well. These changes, in addition to natural variability, both affect and respond to all aspects of the biophysical climate system.  The transition from ice-covered to open water allows for altered air-sea exchange of momentum, heat, light, freshwater, and gas, as well as enhanced surface waves, changes in the planktonic ecosystem, and shifts in migration patterns. In this session, we focus on natural variability and long-term changes in the Arctic and Antarctic seasonal and marginal ice zones. We solicit observational, theoretical and numerical investigations that address variability and change and encourage studies that connect sea ice change in the Arctic and Southern Oceans to at least one other component of the biophysical marine and terrestrial systems, both locally and beyond to lower latitudes.

[CRYOLIST] Recipients of the 2020 IACS-IGS Graham Cogley Award

Dear Cryolisters,

 

It is with great pleasure that the IGS announces the recipients of the 2020 IACS-IGS Graham Cogley Award.

 

The IACS-IGS Graham Cogley Award was established in 2019 in memory of Professor Graham Cogley who made substantial and enduring contributions to glaciology, in particular to the understanding and quantification of glacier mass change. Graham is also recognized for his sustained and outstanding service to the wider glaciological community, including as IGS Chief Editor between 2016 and 2018. The Graham Cogley Award recognizes excellence in glaciological research by student scientists. The award was initiated and is generously sponsored by the Cogley family and is shared between the International Glaciological Society (IGS) and the International Association of Cryospheric Sciences (IACS), with the IGS and the IACS giving out the award in alternate years. For more details on the IGS award and the selection procedure see here.

 

From approximately 70 student-authored papers in the Journal of Glaciology and Annals of Glaciology eligible for the 2020 IACS-IGS Graham Cogley Award we shortlisted nine papers from five countries. From these, the following two glaciologists are awarded the 2020 Graham Cogley Award for their best student-authored IGS papers:

Carlo Licciulli (Univ. of Heidelberg, Germany)

Licciulli C, Bohleber P, Lier J, Gagliardini O, Hoelzle M & Eisen O (2020) A full Stokes ice-flow model to assist the interpretation of millennial-scale ice cores at the high-Alpine drilling site Colle Gnifetti, Swiss/Italian Alps. Journal of Glaciology 66(255), 35-48. https://doi.org/10.1017/jog.2019.82

 

Paul Weber (Univ. of Portsmouth, UK)

Weber P, Andreassen L, Boston C, Lovell H & Kvarteig S (2020) An ~1899 glacier inventory for Nordland, northern Norway, produced from historical maps. Journal of Glaciology 66(256), 259-277. https://doi.org/10.1017/jog.2020.3

 

Both papers are exceptional in novelty and diversity of methods applied, as well as in depth of analysis and quality of presentation. Both works honour Graham Cogley's legacy in analysis of glacier mass balance and glacier change. The diversity through international collaboration on these papers is also notable: Carlo Licciulli is an Italian who completed his doctoral in Germany, and the co-authors are Italian, German, French and Swiss. Paul Weber is from the UK and conducted the research resulting in the winning paper as a visiting researcher in Norway, and the co-authors are Norwegian and British.

 

Many congratulations to these two outstanding junior glaciologists. Carlo and Paul will present their research in the IGS Global Seminar Series on Zoom on Wed 5 August (Thurs 6 Aug in parts of the eastern hemisphere). See recent Cryolist announcements by Prof. Tavi Murray or check https://twitter.com/igsoc for details on the IGS Global Seminar Series.

[CRYOLIST] TR: PhD offer at Grenoble University: multiscale avalanche modelling

Dear colleagues,

 

Please find below a PhD proposal at Grenoble University (INRAE and 3SR laboratory) on multiscale modelling of snow avalanche release.

 

Key points of the PhD:

• Development of an innovative numerical approach

• Applications to natural hazards (snow avalanches)

• Stimulating and multidisciplinary work team

 

Additional information available upon request!

Best regards,

Guillaume Chambon

 

 

PhD proposal:

MPMxDEM double-scale modelling of slab avalanche release

 

Project description

Snow is a fascinating material with a complex and evolving microstructure. Snow avalanches, notably slab avalanches, are generally initiated by failure and collapse in the snowpack of a so-called weak layer, whose thickness can be very small (a few mm). This phenomenon, in which the instability of a whole slope is ultimately controlled by rupture mechanisms at the scale of the microstructure of the weak layer, is intrinsically multiscale.

 

Recent studies in our group explored snow mechanical behavior through discrete element (DEM) simulations based on 3D microstructure data obtained from X-ray microtomography [Mede et al., 2018]. Do to the heavy computational costs, such simulations currently remain limited to the scale of representative elementary volumes (REV).

 

In this PhD, we want to tackle the scale of the snowpack and of the slope, by coupling these microstructure-based discrete simulations with a continuous model. We will build upon recent numerical homogenization approaches developed in geomechanics, notably in Grenoble [Desrues et al., 2019]. These coupled double-scale approaches have the advantage of "naturally" transmitting to the macroscale all the specificities inherited from the complex microstructure of the material (non-coaxiality between stresses and strains, softening, collapse, etc.). In the frame of this project, the macroscopic model will be based on MPM (Material Point Method), which is well suited to modelling large deformations and transition towards flow.

 

The first stage of the work will be dedicated to the development of the coupled MPMxDEM tool, based on preexisting MPM and DEM engines. Particular emphasis will be put on the development of efficient parallelization strategies. To further reduce computing times, efforts shall also be devoted to simplifying the microstructure of the material while preserving the main features of its mechanical response. The code will first be tested and validated in canonical configurations through comparisons with experimental data, both at the scale of the REV (shear and compression tests) and of the snowpack (stability tests). The tool will then be exploited at the scale of the slope to investigate important issues for the forecast and evaluation of natural hazards, such as the influence of topography and snowpack heterogeneity on avalanche release.

 

This PhD is part of ANR project MiMESis-3D (2020-2024), which aims at a better understanding of the metamorphism and mechanical, thermal, and optical properties of snow based on microstructure data. The project brings together a consortium of partners specialized in snow science, geosciences, mechanics, and applied mathematics.

 

Location and practical aspects

The PhD student will share its time between the research unit ETNA of INRAE (Torrent control, Snow and Avalanches) and 3SR laboratory (Soils, Solids, Structures, Risks; Grenoble INP – UGA – CNRS). The two laboratories are located in neighboring buildings on Grenoble Alpes University campus. A close collaboration with CEN (Centre d'Etude de la Neige; Meteo-France – CNRS; P. Hagenmuller) will also be established.

 

Required profile

This PhD requires a solid background (Master 2 or equivalent) in mechanics and/or numerical methods, as well as a keen interest for software development and programming. A previous experience in advanced mechanical modelling (DEM, FEM, SPH, MPM, etc.) will be appreciated.

 

Applications

Candidates shall send their CV and motivation letter to Guillaume Chambon (guillaume.chambon@inrae.fr) et Vincent Richefeu (Vincent.Richefeu@3sr-grenoble.fr).

Application deadline : 15 July 2020.

[CRYOLIST] Vacant PhD in subglacial carbon cycling at University of Copenhagen

I am happy to announce a PhD position in glacial hydrology and subglacial carbon cycling at University of Copenhagen.

 

Recently, there has been discoveries of massive emissions of CH4 and CO2 from the subglacial environment of the Greenland Ice Sheet, but our understanding of the source and the magnitude of emission is very limited. A new project, MetICE, will try to unravel some of the mysteries of subglacial carbon cycling using field measurements and isotope studies.

 

To perform part of this work we seek a highly motivated PhD student with prior experience in Arctic field work involving either hydrology and or greenhouse gases. An integral part of the project is also to develop low-cost sensors for CH4 in air and water (see our proof-of-concept paper on this: https://www.atmos-meas-tech.net/13/3319/2020/amt-13-3319-2020.pdf).

 

In the PhD you will work in a team of researchers (Thomas Blunier from Ice and Climate, Niels Bohr Institute, UCPH; Thomas Röckmann from IMAU, Utrecht University and Christian Juncher Jørgensen, Aarhus University). The PhD is based in Copenhagen (the happiest city on the planet) and involves frequent field work at the Greenland Ice Sheet near Kangerlussuaq, Greenland.

 

The PhD is fully funded for three years at Danish PhD salary. Deadline for application is September 30^th 2020 with a planned start of the PhD February 1^st 2021.

[CRYOLIST] News about the 3rd SOCHICRI Meeting

The SoChiCri team hopes that everyone is doing well these days!

 

Unfortunately, due to the recent developments in the COVID pandemic in Latin America and especially in Chile, the 2020 local committee in consultation with the National committee has decided to postpone the 3^rd Annual Chilean Cryosphere Society Meeting (SOCHICRI) to March 2021. The specific dates will be communicated soon. Considering the uncertainty regarding the spread of the virus, a new date in March of the following year will allow us to develop a hybrid meeting, with in-person and interactive online attendance. The in-person version of the meeting will still be held in the Vicerrectoría de Investigación, Universidad de Concepción (https://goo.gl/maps/QJfwf3dRQj8LEKm96). We are now contacting the authors who have already submitted abstracts and paid the fees in order to allow them to withdraw and arrange refunds, if they require to. Nevertheless, the submission platform will be activated this week, remaining open for more submissions until November 30^th, 2020 in order to allow interested researchers who would like to participate in the next year event.

So, the SOCHICRI team would like to reiterate the previous invitation to all researchers, professionals and students from Chile and abroad to participate in the annual meeting, organized by the Geography and Geophysics Departments of Concepcion University in Chile.

We invite you to send your abstract through the following online form: https://forms.gle/9NLTW4kJGnDt5KM56. Your contribution can focus on any part of the cryosphere subjects, and can include field- or theory-based studies, remote sensing, simulations, legal frameworks, impact and/or risk analyses, water resource assessments and others. Please follow the instructions on the online form to register for the conference and to mention your preferred presentation format (oral or poster). The closing date for abstracts is November 30, 2020.

This next meeting we will offer workshops during the afternoon of the last day of the meeting. We invite all those interested in leading a workshop focused on methods or themes related to the cryosphere to send us your general idea as soon as possible to (sochcri@gmail.com). In addition, we will hold a round-table conversation entitled Cryo-science, cryo-activism and social transformation, where researchers, NGO representatives and other interested parties will meet to discuss and design new research strategies to more closely connect cryosphere science with societal needs. Those interested in taking part of it can also register in the online form.

The registration period will remain open, with the early bird period ending on January 31st 2021, with rates of $22.000 Chilean pesos (students) and $32.000 Chilean pesos (professionals). After that date, the rates will increase to $32.000 Chilean pesos (students) and $42.000 Chilean pesos (professionals). Fees for people who would only participate in the online version will be discussed and decided once we have a better picture of the preferences of potential attendees. An additional question about this topic has been added within the online form.

Updates on travel grants and fieldwork will be sent in a forthcoming communications.

 

Looking forward to meeting you in 2021!

[CRYOLIST] PALSEA-SERCE workshop

Dear Cryolist Community,

 

Following the many challenges posed by the current COVID-19 pandemic, the organizing committee has decided to postpone the PALSEA-SERCE 2020 workshop to autumn 2021.
However, to continue fostering scientific exchanges in the sea level and ice sheet community in these difficult times, the organizers have decided to set up a virtual meeting, named PALSEAExpress, for the dates of September 15th and 16th, 2020. Each day will consist of three hours, divided between invited talks (20 minutes each plus question time) and virtual poster presentations.

 

Meeting times  
September 15th, 10.00 AM UTC - 01.00 PM UTC Find meeting time in your timezone HERE
September 16th, 04.00 PM UTC - 07:00 PM UTC Find meeting time in your timezone HERE

Virtual poster abstract submission
During the two-day meeting, we will reserve time slots for virtual posters.
Abstract submission is now online and will close August 15th, 2020.
You can submit your abstract through this form.

PLEASE NOTE: each abstract will be reviewed by the organizing committee. As the virtual meeting time is limited, we cannot guarantee that we will be able to accommodate all abstracts. Priority will be given to Early Career Researchers and researchers from low GDP countries.

 

We hope to see many of you online in September. Best,

 

Jacky, Alex, Tasha, Jeremy, and Ale

[CRYOLIST] Update on WAIS Workshop 2020

Dear Colleagues,

We hope that you are doing well in these difficult times. In an effort to ensure the health and safety of our community, we want to let you all know that the 2021 West Antarctic Ice Sheet (WAIS) Workshop will not be an in-person meeting this fall. Instead, we are planning to have community-oriented discussions on 6-7 October 2020 focused on addressing racial diversity and inclusion and supporting early-career researchers (ECRs) in the WAIS community. 

One of the defining aspects of WAIS Workshops is the encouragement of interdisciplinary scientific exchanges across career levels, and we want to make sure that there are still forums for such fruitful, engaging discourse among our West Antarctic research community in spite of COVID-19. To retain a semblance of that unique environment, the WAIS Workshop Organizers are planning to facilitate  a series of distributed science sessions for interested community members that will begin before October. These sessions will meet virtually every few weeks as small groups (<15 people) for a series of short research talks (5-10 minutes) followed by WAIS-style discussion. The groups will be shuffled between sessions to promote diverse viewpoints on our scientific questions.

These WAIS activities that are in lieu of an in-person workshop will be at no cost to participants. We plan to provide details on the activities by the end of July. 

In the meantime, however, please reach out to your ECR mentee/mentor that you were paired with at the 2019 WAIS Workshop. If you are new to the WAIS community and/or would like to now participate as an ECR mentee (defined here as undergraduate to ≤10 years from PhD) or as a non-ECR mentor, please contact Lauren Simkins (lsimkins@virginia.edu). 

Sincerely, 

The WAIS Organizing Committee

[CRYOLIST] PhD. Position in Snow Hydrology and Data Assimilation, SLF, Davos, Switzerland

The Research Group Snow Hydrology (SLF Davos, WSL) is offering one PhD position studying "Improved methods for incorporating observational data into physics-based, multi-layer snow models", starting in October 2020.

You will develop novel data assimilation methods, while working with established techniques to inform and improve complex, multi-layer snow model simulations. SLF provides an enriching environment for the successful candidate to develop their research working alongside and collaborating with a motivated team of snow and ice researchers. With direct access to a national snow monitoring network and modern remote sensing data, your doctoral research will demonstrate how various data streams can be dynamically integrated into complex snow models. You will develop improved means of enhancing snow model performance at times and places where observations are available and most importantly how to best leverage this information to improve simulations when observations are unavailable. Research findings will be used to directly improve operational snowmelt forecasts while also benefitting the research community. You will present your scientific results in journal publications and at international conferences.

[CRYOLIST] CryoSat-2 is planning to move home (but just down the road)

Dear CRYOLIST

 

ESA have developed a plan to manouevre CryoSat-2 into a new orbit that is synchronized with ICESat-2. The campaign is tentatively known as Cryo2Ice.

 

The new CryoSat-2 orbit provides ground tracks that coincide with those of ICESat-2 for 500-1000 km every 1.3 days.  It involves only a small (<1 km) move for CryoSat-2, and can be performed with no significant disruption to the mission – i.e. with no unusual risk, and with no significant consumption of fuel or sensor downtime – as it is comparable to orbit maintenance. The ground track coincidence can be targeted at specific geographical regions, and can be alternated with about half the initial orbital adjustment. The new orbit will provide identical spatial and temporal sampling of land and sea ice, with a slightly shifted ground track that will benefit applications seeking new coverage.  Further details can be found below.

 

Although the Cryo2Ice campaign has been planned for some time, the implementation was paused due to COVID-19. However, there is a favourable opportunity to begin this manouevre on 16^th July which would achieve the new orbit by early August, in plenty of time for the Arctic sea ice season.

 

We are excited to inform you of this new opportunity, as it will allow everyone to explore the continuity and complementarity of the two missions. If you would like to lend your support, please add your name to the community letter which is being assembled:

----------------- Further Details ------------------------

 

1. The Proposed Manouevre

The proposed synchronisation involves a modest (less than 1 km) adjustment to the CryoSat-2 orbit semi-major axis and will provide coincident ground tracks for considerable distances (up to 1000 km) every 19 orbit revolutions (1.3 days). The orbital adjustment can be achieved in a succession of thruster burns that are comparable in magnitude to orbit maintenance manoeuvres and are therefore considered nominal (normal) risk. The manoeuvre can also be completed within a relatively short (two week) period and will involve negligible (minutes of) data loss, and negligible (0.5 kg of) fuel consumption. The synchronisation can be optimized to favour regional ground track coincidence in either hemisphere, and the proposed start date of July 16^th 2020 will allow synchronisation over the Arctic in time to capture the winter sea ice season. Alternating the geographical coincidence between hemispheres can be completed with a smaller (and shorter duration) adjustment to the orbital phasing. In our view, the proposed manoeuvre is effective (in terms of the synchronisation it achieves), low cost (in terms of consumption of fuel and loss of data), and low risk (in terms of the departure from nominal activities).

2. The Impact

The main concern relating to the manoeuvre relates to the potential impact on the mission primary data streams, namely measurements of sea ice and land ice thickness change. However, since the synchronisation can be achieved with only a minor adjustment to the nominal orbit, the spatial and temporal sampling of the ground track is not significantly modified, and overall the synchronised orbit provides slightly improved capability to sample trends in land and sea ice thickness. In our view, the proposed manoeuvre will not disrupt the primary measurement capability of CryoSat-2.

3. The Scientific Opportunity

The scientific value of the proposed synchronisation is considerable. It will provide a unique opportunity to obtain near-coincident measurements of sea ice, land ice, and ocean surface elevation acquired at laser and radar frequencies over large (mesoscale) spatial scales and systematically. With such measurements, we can assess for the first time the continuity and consistency between radar and laser measurements of surface elevation changes, and we can then explore their complementarity for monitoring differences in the scattering properties of snow and ice. For example, the depth of snow on sea ice floes is a primary source of uncertainty in both radar and laser altimeter retrievals of sea ice thickness, and the synchronised orbits will allow us to develop a retrieval for this parameter from dual-frequency satellite observations alone. These measurements will pave the way for the next generation of satellite altimeter systems, such as the CRISTAL High Priority Candidate Mission in development as part of the Copernicus Expansion Program. Over land ice, a synchronised campaign will allow us to quantify spatial and temporal variations in radar penetration into the snowpack and laser scattering within the near surface spindrift. Over ocean surfaces, the altered sampling of the synchronised orbit will lead to improved estimates of the mean sea surface which will in turn lead to more precise estimates of marine gravity, seafloor bathymetry, dynamic ocean topography, and sea ice freeboard. We conclude, therefore, that the scientific potential of the synchronised orbit is huge.

To Whom It May Concern

We are writing to offer our support for the proposed Cryo2Ice campaign, which requires a small adjustment to the CryoSat-2 orbit to allow synchronised ground track sampling with ICESat-2.

A synchronised campaign with ICESat-2 represents a unique opportunity to explore the benefits of dual frequency satellite altimetry, ranging from cross-calibration of time-series developed from each mission to developing novel retrievals that make use of their complementary measurement capabilities. In particular, as a community that depends heavily on polar altimetry, we recognise that such a campaign would provide critical support for the CRISTAL mission concept, which represents the best prospect of securing a long-term future measurement capability. An adjustment to the CryoSat-2 orbit would also lead to an altered ground track distribution, benefitting numerous important geophysical applications.

Our main concern surrounds the potential risk or disruption that an orbit manoeuvre could bring. We understand, however, that a synchronisation has been identified by ESA and expert advisors that will (i) require no significant alteration to the CryoSat-2 orbit, (ii) present no significant risk to the CryoSat-2 platform or demand on its resources, (iii) lead to no significant disruption to the CryoSat-2 data stream, and (iv) present no significant change to the mission capability to monitor land and sea ice thickness trends. On this basis, we offer our support for the implementation of the Cryo2Ice campaign, and we look forward to receiving the new measurements in due course.

Yours sincerely
