[CRYOLIST] Session on Antarctic slope and rise sediments at ISAEAS 2019, Incheon

Dear colleagues

Please consider submission of an abstract to the following session at the XIII ISAES conference (22-26 July 2019, Incheon, Republic of Korea):

https://www.isaes2019.org:12090/home/

Abstract submission deadline is until March 31st.

Title: Theme 4. Glacial history of Antarctica and the Southern Ocean

Session: Marine sedimentary sequences from the Antarctic continental slope and rise: Records of ice-sheet dynamics and Southern Ocean history during the Late Cainozoic

Description:
Fluctuations in ice-sheet extent and related changes in water-mass formation and circulation controlled deposition on Antarctica's continental margin throughout the Late Cainozoic. Palaeo-ice stream advances through cross-shelf troughs during cold periods increased the supply of glacigenic debris to the slope, with gravitational processes transporting this material further down to the rise. Locally, bottom currents focussed the deposition of fine-grained detritus in high-accumulation sediment drifts. Variations in the extent of floating ice above the margin steered plankton productivity in surface waters as well as the formation of dense shelf waters, i.e. precursor water masses for Antarctic Bottom Water, and thus bottom-current flow in the deep sea. Glacial-interglacial changes in ice-sheet volume caused variations in the delivery of iceberg-rafted debris to the margin. Therefore, sedimentary sequences from the Antarctic slope and rise provide unique and continuous records of past ice-sheet dynamics on land as well as past changes in water-column structure and circulation in the Southern Ocean. The session will draw together findings from proxy-investigations on these archives. We encourage presentations focussing on reconstructions of Neogene to Quaternary ice-sheet history and Southern Ocean variability, thereby contributing to the goals of the SCAR programme PAIS (Past Antarctic Ice Sheet dynamics).

Confirmed presenters:
Carlota Escutia (Instituto Andaluz de Ciencias de la Tierra, Spain), Robert McKay (Antarctic Research Centre, New Zealand), Taryn Noble (University of Tasmania, Australia), Juliane Müller (Alfred-Wegener-Institut, Germany), Li Wu (Tongji University, China), Sunghan Kim (Korea Polar Research Institute, Republic of Korea)

We look forward to seeing you in Incheon!
Jae Il Lee, Gerhard Kuhn and Claus-Dieter Hillenbrand (convenors)

Session description: The most dramatic changes in the Anthropocene are observed in the cryosphere such as the rapid decline of sea ice, retreat of glaciers and warming of permafrost. However, warming in the high latitudes is also affecting processes in the lower latitudes. Understanding complex physical, geochemical and biological dynamics often requires a multidisciplinary approach and technical progress is promising for advancing our current knowledge of the cryosphere. This session welcomes contributions to our understanding of past, current and future changes in the Polar Regions including field observations, laboratory data, remote sensing, modelling approaches and method development.

Hi Grace,

Hope you are feeling a little better.

Suspect you have seen this, but I thought it worth highlighting. I saw John Woodward last week and it's clear they are hiring very strategically, i.e. strong focus on cryosphere (which you sort of study...!).

[CRYOLIST] Post-doctoral scientist position at the UCL, Belgium: modelling surface mass balance in Antarctica

The Georges Lemaître Centre for Earth and Climate Research (www.uclouvain.be/teclim) / Earth and Life Institute of the Université catholique de Louvain, Louvain-la-Neuve, Belgium invites applications for the following position:

Foreign Post-doctoral Fellow

Starting date: ideally May 1

Full time position for 24 months

Net monthly salary 2300-2500 € (depending on experience - this includes social insurances).

The candidates must not have spent more than 2 years in Belgium over the last 3 years and should not have obtained their PhD more than 6 years before the starting date of the grant.

The starting date is flexible but should not be later than July 1.

The postdoctoral researcher will work on the project 'East Antarctic surface mass Balance in the Anthropocene : Observations and multiscale modelling" (Mass2Ant) funded in the framework of Belgian Research Action through interdisciplinary networks (Brain.Be – BELSPO).

The project (www.mass2ANT.be ) aims to understand the local processes responsible for the variability of surface mass balance in the Princess Ragnhild Coast (PRC) region (Antarctica) and to document the changes during the last 300 years. A particular attention is paid on the links between local, regional, and large scale processes to determine the origin of the variability of the surface mass balance. This will allow assessing if the observed changes over PRC (e.g. mass gain) are representative for larger areas and if these are the result of anthropogenic forcing and/or linked to the natural variability of oceanic and atmospheric circulation.

The successful candidate will be in charge of analyzing the origin of the climate variability recorded by three ice cores collected on ice rises in the PRC regions. A goal is to relate the signal common in the three cores to nearby and more distant data in order to infer large-scale connections. Those analyses will be based on the results of global, regional and small-scale models as well as observations.

Required qualifications:

- To have a PhD in climatology, Earth science or related field (physics, informatics) with previous experience in Earth science;

- To have published in peer-reviewed international journals;

- To have experience in computational programming and in managing large data sets;

- An experience in climate or ice modelling is a strong asset;

- To have demonstrated verbal and written communication skills in English;

- To have interest in working in a multidisciplinary team environment.

Applicants should send via e-mail to Hugues Goosse (hugues.goosse@uclouvain.be). (i) a statement of research experience, qualification and interest, (ii) a complete CV including a list of publications, and (iii) the name of two scientists that could provide a letters of recommendation

Review of the applications will start March 1 and the call is open until the position is filled.

Non-parametric Mixture Methods for Improved Satellite Altimeter Retrievals over Ice Sheets

Supervisors: Mal McMillan, Marco Battiston, Amber Leeson & Chris Nemeth

For more information contact Mal McMillan on m.mcmillan@lancaster.ac.uk

This project offers the exciting opportunity to improve estimates of ice sheet mass loss, by developing novel approaches to processing complex satellite datasets. This project is particularly well-suited to those with a numerate background in mathematics, statistics, physics, computer science, or engineering, who want to make the step towards more applied study in the fields of environmental science and geophysics.

For the past 25 years, satellite radar altimeters have provided the longest continuous record of ice sheet response to climate change, detailing the increasing rates of ice melt and discharge into the oceans. One of the principal remaining challenges associated with processing these data is to retrieve estimates in complex topography, across areas such as rugged coastal terrain and the mountainous regions of the Antarctic Peninsula. These rapidly changing areas are amongst the most important to measure; yet the conventional retracking methods used to process altimetry data often struggle to adapt to the true complexity of the detected signal.

In this project, you will work with data from the novel Sentinel-3 Delay-Doppler altimeter, to develop new altimeter waveform processing techniques, based upon the field of Bayesian non-parametric mixture methods. These mixture methods offer a new approach for retracking altimeter echoes, because no strong assumptions are required about the topography of the ice sheet surface; instead this information is inferred directly from the data. Here we will focus specifically on the class of dependent Dirichlet process mixture models because they allow for highly non-Gaussian behaviour, skewness and multimodality in the waveform shape, all of which are expected features of the data. Following method development and proof-of-concept studies, you will apply this new approach to map contemporary rates of surface elevation change across the challenging coastal regions of Greenland and Antarctica, with the ultimate aim of delivering improved estimates of the contribution of both ice sheets to global sea level rise.

Diagnosing Antarctic ice shelf risk using coupled computational modelling

Supervisors: Amber Leeson, Andrew Orr (BAS), Gordon Blair, Chris Nemeth, Ryan Hossaini

For more information contact Amber Leeson, a.leeson@lancaster.ac.uk

75% of the Antarctic ice sheet is ringed by floating ice shelf, which is formed as the ice sheet spreads out over the sea. Since ice shelves are low-lying with respect to grounded ice, they are particularly vulnerable to atmospherically induced melting. In fact it is thought that surface melting induced the collapse of the Larsen B ice shelf on the east side of the Antarctic Peninsula in 2002, which resulted in a two- to six-fold increase in the flow of glaciers which formerly fed the shelf (Scambos et al., 2004). This has resulted in an ice loss to the sea equating to around one-third of the net loss from the entire region since the collapse event. The evolution of ice shelves relies on complex interactions between the atmosphere and the ice surface, and so in order to assess the degree to which the other Antarctic ice shelves are at risk a coupled modelling approach at high spatial resolution is required. However models do not yet exist which both 1) simulate climate on spatial scales of < 5km and 2) incorporate atmosphere-ice interactions deep enough into the firn pack which lies atop the ice. In this project we will develop computational infrastructure to couple the 3D Met Office Unified Model (UM) with the 1D community firn model (CfM) in order to address this gap. The model will be optimized using a fully Bayesian approach (e.g. Bobak et al., 2016) to select a model configuration and estimate the model parameters. High resolution simulations over the remaining ice shelves on the Antarctic peninsula (e.g. Larsen C, which is twice the size of Wales) will be performed under a range of future climate forcings out to 2100 and uncertainty in these simulations will be explored. This project will unite the disciplines of computer science, environmental science and statistics in order to provide a robust assessment of present and future stability of these shelves and ultimately determine which are at risk of collapse under a warming climate.

Automated quantification of Greenland ice sheet melting using spaceborne radar data and multivariate changepoint methods

Supervisors: Amber Leeson, Rebecca Killick, Anna Hogg (CPOM)

For more information contact Amber Leeson, a.leeson@lancaster.ac.uk

Since the 1990s, the Greenland Ice Sheet has shifted from a state of near mass balance, to one of significant mass loss and has contributed approximately 10% to the measured global sea level rise during the last twenty years (Church, 2013). In the past decade, the rate of ice loss from Greenland has increased and the ice sheet has experienced episodes of rare and extreme surface melt. The dramatic increase in spatial and temporal coverage of satellite observations of the Greenland ice sheet offers a new opportunity to greatly improve our understanding of ice sheet melting, both in terms of these extreme melt events and under climatically 'normal' conditions. For example, Synthetic Aperture Radar (SAR) data acquired by the Sentinel series of satellites have previous been used to map and monitor snowmelt in the European Alps (e.g. Nagler et al., 2016). Here we propose to develop an image segmentation approach, based on changepoint methods, to derive melt area and volume from Sentinel 1a SAR backscatter images of the Greenland ice sheet from 2014 up to now. In the univariate and multivariate time series context, changepoint methods are commonly used to segment ordered data (e.g. Truong et al., 2018). This project will extend these ideas to the Sentinel 1a SAR data thereby creating a new framework for segmenting images using changepoint methods in addition to improving our understanding of Greenland ice sheet melting. The project will be based in Lancaster and there will be an opportunity for the student to pay an extended visit to the external partner based at the Centre for Polar Observation and Modelling in Leeds. Through this partner, methods developed during this PhD could potentially become part of the routine processing of these satellite data and be used to monitor future changes to Greenland ice sheet melting in near-real time.

[CRYOLIST] Announcement of session on 'Polar Modelling (Polar CORDEX)' at the upcoming IUGG conference in Montreal

Dear Cryolist members,

We will be holding session M05 on 'Polar Modelling (Polar CORDEX)' at the upcoming IUGG conference in Montreal, from 8-18 July 2019. Please see below for a description of the session. The deadline for abstract submission is 18 February, which can be submitted using this link: <http://iugg2019montreal.com/abstract-submission.html>. Further details on the conference are available here: <http://iugg2019montreal.com/>. We are very much looking forward to your contribution to this session.

M05 - Polar Modelling (Polar CORDEX)

Convener: Andrew Orr (UK)

Co-conveners: John Cassano (USA), Annette Rinke (Germany)

Description

The climate of the Polar regions has experienced significant changes over recent decades. Regional information on variability and change of the Polar climate is urgently needed but often deemed unreliable. The Polar CORDEX (COordinated Regional Downscaling EXperiment) project was initiated to develop regional climate downscaling of both the Arctic and the Antarctic to provide an accurate description of regional-to-local scale climate phenomena and their variability and changes. We encourage submissions that advance understanding of the processes that control polar climate variability in regional climate models. We also encourage submissions that examine model evaluation, coupled modelling, projections, and impact studies. This symposium also aims to promote stakeholder/user engagement.

Best wishes,

Andrew

[CRYOLIST] USAPECS Call for 2019 Board Members

USAPECS (http://usapecs.wixsite.com/usapecs) would like to announce a call for applications for its executive board for 2019. Members of the USAPECS Board are expected to work together to develop and execute activities that they think will be of interest and beneficial to Association of Polar Early Career Scientists (APECS) members living in the US. The activities can include anything you're passionate about, from organizing social events or panel discussions at meetings to running a Reddit AMA session or organizing a webinar. This past year we produced a blog series focusing on science communication, and we would love for members to organize something similar this next year! We'd also love volunteers to continue our Polar Film Festival in September (http://usapecs.wixsite.com/usapecs/copy-of-polar-film-festival-2018) and organize a panel and social at the American Geophysical Union Fall Meeting in Washington DC in December, as we did this year--which focused on diversity and inclusion in the polar sciences (http://usapecs.wixsite.com/usapecs/agu-2018-early-career-panel)!

It's a great opportunity to become more involved in the broader polar science community within the US. The activity (or activities) you help with are totally up to you! The time commitment varies depending on your level of involvement, but is typically an hour or so per month unless you are particularly involved in an activity (like coordinating writers for a scicomm blog series or leading the polar film festival organization).

If you're interested in serving on the USAPECS Board in 2019, please send an email to USAPECS@gmail.com with your name, title of your current position (undergrad, Masters student, PhD student, postdoc, faculty, etc), where you are employed, and a few short sentences on activities you would like to help organize this year. Applications are due January 31st. We'll have an online meeting to welcome new members the following week.

We hope to see your applications!

[CRYOLIST] Debris-covered glacier session at IUGG 2019

Dear Cryolisters,

Please consider submitting an abstract to our session on debris-covered glaciers at IUGG 2019 (http://iugg2019montreal.com) – the full session description follows below.

C09 – DEBRIS COVERED GLACIERS

Conveners: Francesca Pellicciotti, Duncan Quincey, Patrick Wagnon

Debris-covered glaciers, mantled in a layer of continuous or discontinuous debris over all or part of their tongues, are common in many mountain ranges of the world. Debris alters the surface energy and mass balance of glaciers and thus the way these glaciers react to climate. The past decade has seen a dramatic advance in our understanding of their surface processes, mass balance, hydrology, dynamics and long-term evolution. However, many open questions remain. Also modelling debris-covered glaciers remains challenging. This symposium aims to bring together new research results from a variety of different approaches, including numerical modelling, observations and remote sensing, to understand debris-covered glaciers, their processes and main controls. In particular, we invite contributions that include, but are not limited to: i) the formation, characteristics and movement of supraglacial debris; ii) studies of debris-covered glacier energy balance and mass balance, with special emphasis on surface processes such as the formation of supraglacial ponds and cliffs; iii) their hydrology, including englacial and subglacial characteristics; iv) debris-covered glaciers dynamics; v) remote-sensing observations and numerical modelling of debris-covered glaciers and prediction of their changes in response to climate; vi) long term evolution of debris-covered glaciers, reconstructions of former glaciers and their climatic interpretations; vii) the development of hazards associated with debris-covered glaciers such as glacier lake outburst floods or debris flows.

[CRYOLIST] IGS Madison abstract submission and the US government shutdown

Dear Cryolist members

As you may be aware of there is a US government shutdown in effect. As a result of this we have had several US employees contact us via their personal accounts indicating they intended to submit something but are currently unable to do so.

Because of this, we have decided to extend the abstract submission deadline until midnight of the 4 February, thus giving the US government almost two weeks to sort out the dispute between the US President and Congress.

This will hopefully give the affected US federal employees enough time to submit their abstracts.

And those of you who have not submitted your abstract now have a second chance to do so.

We have a substantial number of very interesting abstracts submitted so this promises to be yet another great IGS symposium.

Please submit your abstract at https://www.igsoc.org/abstracts/80a/

You can access the second circular at https://www.igsoc.org/symposia/2019/madison/

All the best

[CRYOLIST] ANTPAS session – ISAES 2019

Dear colleagues,

We would like to draw your attention to a session organized by the ANTPAS (Antarctic Permafrost and Soils) at the upcoming 13th International Symposium on Antarctic Earth Science (ISAES 2019) that will be held in Incheon, Republic of Korea from 22-26 July 2019.

The deadline for abstract submission is now open and will close by 31 March 2019.

Within the umbrella of the ANTPAS, there will be a session on "Permafrost and Periglacial ice free areas in Antarctica"

ANTPAS (Antarctic Permafrost, Periglacial Environments and Soil) promotes the research on permafrost and periglacial environments that characterize the ice free areas in Antarctica. This session focuses on permafrost, on the overlying active layer, on the related landforms as well as on the soils that characterize almost all the ice-free areas in this continent. Thermo-physical conditions of permafrost and the active layer are very variable in the Antarctic, both in space and in time, and have accelerated over the last 20 years. Indeed, some areas of the Antarctic Peninsula have recorded after one of the strongest warming rates on Earth while in Continental Antarctica, after remarkable climate stability, a warming trend together with an increase of solar radiation are leading large changes in the ice free areas. Therefore, the analyses of the observed patterns and the response of the landscape can provide insights on recent and future changes in permafrost regions, which can be also used to examine ice/land/ocean/atmosphere feedbacks influencing regional, hemispheric and global climate conditions.

In addition, Antarctic permafrost areas are also the best terrestrial analogue of Mars conditions and therefore represent an unique opportunity to test technology and models for the future Martian exploration.

Transdisciplinary contributions from permafrost, soils, geomorphology, microclimate, hydrology, geophysics and remote sensing are expected. Although not exclusively, the session aims to contribute to the new questions from the SCAR Horizon Scan emphasizing on the significance of the fast changing terrestrial environments, for example:

- What are and have been the rates of geomorphic change in different Antarctic regions, and what are the ages of preserved landscapes?

- How will permafrost, the active layer and water availability in Antarctic soils and marine sediments change in a warming climate, and what are the effects on ecosystems and biogeochemical cycles?

We kindly invite researchers working on these topics to send their contributions to this session.

With best regards,

Marc Oliva
