The Polar Science Center at the University of Washington, in collaboration with the eScience Institute and the National Aeronautics and Space Administration (NASA), announce a “hackweek” for Cryospheric Science with ICESsat-2 (CSI).

The ICESat-2 Cryospheric Science Hackweek will bring together experts from the ICESat-2 science team, data providers and application program interface (API) designers, and data science experts, with researchers who want hands on experience with using and manipulating geophysical data from ICESat-2. Participants will learn about ICESat-2 fundamentals, data formats, tools, and how to get to results quickly, as well as technologies used to access and process ICESat-2 data with a focus on the cryosphere.

Introductory lectures will be combined with open data exploration, tool development, sample research applications, and community building. Mornings will consist of interactive lectures, and afternoon sessions will involve facilitated exploration of datasets and hands-on software development.

Participants are expected to have some experience with programming and analysis of remote sensing data.

To better design this event, organizers invite those interested to complete a short survey.

Application deadline: 2 November 2018.

Objectives:
The main goal of the Joint Summer School 2019 is to provide participants with innovative practical and methodological skills to characterize complex terrain and object features using close- and near range remote sensing techniques. The Summer School will be the third edition after two successful implementations in 2015 and 2017.

Teaching Methods:
Theoretical lectures will be complemented by fieldwork assignments and hands-on data processing sessions using different novel software. The assignments will be divided into two different tracks. One track will focus on mountain research, the other on sensor and data processing techniques.

A variety of sensor systems will be available for data acquisition in the high mountain surroundings of the summer school venue, including terrestrial laser scanners, unmanned aerial vehicles and spectral cameras.

A poster session on the participants' current research interests and work will stimulate open exchange and discussion between students and lecturers in a relaxed atmosphere.

Thematic focus will be on mountain research, and will include vegetation characterization, (deformation) monitoring for glaciology, geomorphology and natural hazard research.

Technical focus will be on sensor and data aspects, such as sensor modelling, calibration, data acquisition, 2D and 3D data fusion, geometric methods for information extraction from point clouds and (multispectral) images and data quality assessment.

Theoretical focus will address critical steps within a processing chain, such as impact of registration, choice of stand points during data acquisition and derivation of deformation vectors, issues related to multispectral image analysis etc.

Practical exercises using predominantly open source software, deepen the conveyed knowledge and help all participants establish a workflow for their research.

Venue:
The Summer School will take place in and around Obergurgl, at almost 2000 m the highest village in Austria. The main venue is the Obergurgl University Center. Here lectures will take place and accommodation is provided to all participants. Directions will be available via the website. Please note that fieldwork will take place in a mountainous environment, which requires surefootedness.

Registration deadline: 30 November 2018.

The role of non-governmental actors (NGA) in the polar regions has been discussed in different articles and books, but a comprehensive volume assessing their normative role for the lives of people, institutions and laws in both the Arctic and Antarctic has yet to be released.

The planned volume Non-governmental Actors in the Polar Regions aims to fill that gap. The proposal will be submitted to a major academic publisher, such as Springer or Routledge.

We therefore invite 200-word Abstracts on the topic, which can range from political sciences, social sciences, law or economics, by 15 June, so that a full-scale proposal can be developed. We would also welcome balanced commentaries, which highlight positive and negative aspects of NGA-presence in the polar regions. The idea is to create a volume consisting of research articles (9,000-11,000 words), research notes (3,000-5,000 words) and commentaries (2,000-3,000 words).

Suggested topics are (but are not limited to):

– The role of indigenous organisations in Arctic law- and policy-making
– Tourism enterprises in the polar regions
– Non-governmental organisations in environmental decision-making
– Businesses and companies in polar environments
– Subcontractors in Antarctic operations

Please send your Abstracts to Nikolas.sellheim (a) gmail.com and Marzia.scopelliti (a) gmail.com.

We look forward to working with you on this project!

Following successful CHGCS 2017 in Wuhan, China (in conjunction with the ISPRS Geospatial Week 2017), CHGCS 2019 will provide an opportunity for all professionals involved in cryosphere and hydrosphere to share research ideas and results, foster and enhance cooperation, draw inspirations and maximize potentials. It will take place on June 14, 2019, in Enschede, the Netherlands, organized by ISPRS WG III/9 Cryosphere and Hydrosphere.

The themes of the event cover a wide range of remote sensing research and applications relevant to cryosphere and hydrosphere, including, but not limited to the following aspects:

• Ice sheets, glaciers, and ice shelves
• Sea ice in the Arctic and Antarctic
• Mass balance
• River and lake ice
• Albedo at high latitudes
• Permafrost
• Cryosphere-atmosphere interaction
• Himalayan cryosphere
• Surface water and groundwater hydrology
• Coastal environments and sea-level rise
• Data assimilation and cryospheric and hydrological models
• Retrieval of satellite cryospheric and hydrological parameters

There have been many recent changes to better observe Alaska from the Geostationary Operational Environmental Satellite (GOES) perspective. The most significant change was on February 12, 2019 when GOES-17 became NOAA’s operational West geostationary satellite. The Advanced Baseline Imager (ABI) has spectral bands covering the visible, near-infrared and infrared portions of the electro-magnetic spectrum. The ABI represents a major improvement from the legacy GOES imagers for many attributes, such as those relating to: spectral, spatial, temporal, radiometric, and image navigation/registration. An on-board cooling issue associated with the Loop Heat Pipe on GOES-17 causes degradation for certain periods of the year, at certain times, mostly at night. The affected spectral bands are those with wavelengths greater than 4 micrometers with effects that start with biasing, striping, banding, and ultimately complete saturation for the most affected bands. In order to mitigate the impacts of this issue, improvements to the calibration procedures are improving the image quality before and after saturation occurs. These improvements include a modification to the ABI timeline in the 10-min Full Disk flex mode, predictive calibration, and other changes. Once a spectral band is saturated, there is little that can be done to better calibrate the data. The current status of Level 2 or derived products, such as cloud heights or atmospheric motion vectors, from the GOES-17 ABI will also be covered.

We strongly encourage pre-registration for webinars. The audio portion of the call is through a toll-free phone line and the slide presentation is streamed via computer.

The annual international user meeting for the ice-flow model Úa will this year be held at Northumbria University, Newcastle, United Kingdom.

Úa is a finite-element ice-flow model. It is easy to use, robust, and an ideal tool to solve flow of ice sheets, ice shelves and alpine glaciers, and for ice-flow problems involving grounding line migration (https://sway.com/A3ihHbhXG59GwsYf).

The meeting is suitable for both new and experienced users.

As in previous years, there will be an introduction to the use of model and presentations by current users in the mornings. The afternoons can be used to set up and run models, and participants are encouraged to work on their own modelling problems.

One of the focal points of this year's meeting is ice-ocean interactions, and Katlin Naughten from BAS and Jan De Rydt from Northumbria University will give an overview over current Úa+MIGgcm coupling capabilites. Adrian Jenkins from BAS will also give a lector on ice+ocan interactions.

The number of places is limited to 20. There is no course fee. Participants are required to take care of their own accommodation and travel arrangements. There some scope for contributing towards travelling expenses in justified cases.

In response to feedback from last year meeting, there will be an optional further ÚaThon week (May 17-21) where participants can develop their models further under supervision.

Further details about the program will follow closer to the date of the meeting.

For information and registration please send an email to Hilmar Gudmundsson (hilmar.gudmundsson at northumbria.ac.uk).

The International Glaciological Society will hold an International Symposium on ‘Five Decades of Radioglaciology’.

THEME:

Radio echo sounding is a powerful geophysical approach for directly characterizing the subsurface conditions of terrestrial and planetary ice masses at the local, regional and global scales. As a result, a wide array of orbital, airborne, towed and in situ instruments, platforms and data analysis approaches for radar sounding have been developed, applied or proposed. Terrestrially, airborne radar sounding data has been used in glaciology to observe ice thickness, basal topography, englacial layers and for more than five decades. More recently, it has also been exploited to estimate the extent and configuration of subglacial water, the ice sheet surface, the geometry of subglacial bedforms, the spatial variation of melt, temperature, and the transition between frozen and thawed bed. Planetary radar sounders have been used or are planned to observe the subsurface and near-surface conditions of Mars, Earth’s Moon, comets and the icy moons of Jupiter. These instruments provide critical subsurface context for surface sensing, particle, and potential-field instruments in planetary exploration payloads. This symposium will discuss advances in radar sounding systems, mission concepts, signal processing, data analysis, modeling and scientific interpretation.

SUGGESTED TOPICS:

We seek papers and presentations that advance the understanding of radar sounding and its use in physical glaciology. Key focus areas include (but are not limited to):

1. Radar systems: development, performance and platforms
2. Data: intercomparison, validation and release
3. Radar processing: propagation, inversion and automation
4. Englacial structure: layers, deformation and accretion bodies
5. Attenuation: near surface properties, temperature and chemistry
6. Bed conditions: topography, roughness, thermal state and hydrology
7. Interpretation: comparing observations with modeling and theory.

PROGRAM:

True to tradition, the symposium will include oral and poster sessions interlaced with ample free time to facilitate interactions between the participants. Additional activities include an opening icebreaker, a banquet dinner and an excursion during the mid-symposium afternoon break.

ABSTRACT AND PAPER PUBLICATION:

Participants who wish to present a paper (oral or poster) at the Symposium will be required to submit an abstract by 11 March 2019. Accepted abstracts will be posted on the Symposium’s website. The Council of the International Glaciological Society will publish a thematic issue of the Annals of Glaciology on topics consistent with the Symposium themes. Participants are encouraged to submit manuscripts for this Annals volume. The deadline for submission of Annals papers is 1 August 2019.

The Eastern Snow Conference (ESC) is a joint Canadian/U.S. organization founded in the 1940s originally with members from eastern North America. Today, our members come from the United Kingdom, Japan and Germany, as well as North America. Our current membership includes scientists, engineers, snow surveyors, technicians, professors, students and professionals involved in operations and maintenance. The western counterpart to this organization is the Western Snow Conference (WSC), also a joint Canadian/US organization.

After last year’s celebration of the 75th meeting of the ESC in Washington, D.C., we return to a familiar venue in rural Vermont in close proximity to a long-time ESC supporter, the Cold Regions Research and Engineering Laboratory (CRREL), Hanover, New Hampshire, USA.

The scientific program is open to sessions on theoretical, experimental, remote sensing, modeling and operational studies of snow, ice, and winter hydrology. The ESC has only a plenary session (oral and poster viewing), allowing time to view and discuss the research of each participant. You are invited to submit an abstract for an oral or a poster presentation (please indicate type). Using the template available, an abstract of 200-250 words should be submitted by 12 April 2019.

Please visit the website above for more information.

The Arctic region is changing rapidly. On the one hand, ecological, cultural, social and economical changes pose challenges for well-being and sustainable development and on the other hand, some of the changes also create new possibilities. In the Arctic Arts Summit 2019 the challenges and circumstances in the Arctic are seen as 'laboratory' in which sustainable art and cultural policy is developed in collaboration with all of the Arctic counties. Artists and representatives of art and cultural policy will discuss the theme and promote circumpolar collaboration. The event will be the second Arctic Art Summit: the first one was arranged in Harstad, Norway, in 2017.

Artists and other actors of art and cultural sector and policy will attend from all of the countries that are members of the Arctic Council: Canada, the Kingdom of Denmark, Finland, Iceland, Norway, the Russian Federation, Sweden and the United States. In addition, participants from countries that show interest towards the Arctic matters are invited: representatives of China, Japan and Scotland. International journalists are also invited.

The key aim of the Arctic Arts Summit 2019 is to support art and cultural sectors in the circumpolar collaboration. We need to recognize, develop and promote sustainable and responsible models of action, long term planning, infrastructure in the creative field and cooperation in education. The indigenous art and cultural policy as well as interdisciplinary research on the impact of the art and culture are essential themes of the summit.

When planning your travel to Summit please notice the possibilities for visiting other academic and cultural events too. The Cumulus conference “Around the Campfire - Resilience and Intelligence" on 27 May - 1 June 2019 invites you to discuss the themes of resilience and intelligence. Just after the Summit, The Silence Festival gathers the most interesting performances and artists from the fields of contemporary circus and music to Kaukonen village (6 June - 9 June). The Midnight Sun Film Festival is an annual five-day film festival in Sodankylä (12 June -16 June).
