Deadline Approaching-Workshop: Greenland Ice Sheet Ocean Observing System (GrIOOS), December 2015

GRISOA two day workshop will be held on December 12-13, 2015, in San Francisco, USA, to discuss the design and implementation of a Greenland Ice Sheet Ocean Observing System (GrIOOS). The aim of GrIOOS is to provide long-term time series of critical /in situ/ glaciological, oceanographic and atmospheric parameters at several key locations around Greenland. Observations will provide much needed information on the time-evolving relationships between the different climate forcings and glacier flow. GrIOOS was one of the key priorities identified at the 2013 US CLIVAR-sponsored International Workshop on Greenland Ice Sheet Ocean Interactions (GRISO) organized and summarized in the workshop report.

Specific goals of the GrIOOS workshop are to discuss:

  • the motivation for specific measurements;
  • integration with existing related long-term measurements around Greenland;
  • identification of key sites;
  • identification of instrumentation.

A workshop report will be drafted after the workshop and circulated for community input.

The workshop will be limited to ~35 participants. Expressions of interest to attend are solicited from the international community at this time (one page maximum). These should be sent to by *August 23, 2015* and state clearly the proposed contribution to the workshop. Expressions of interest from groups representing a particular discipline, technique, or field site are strongly encouraged. The Workshop Steering Committee (see below) will select participants to represent the glaciological, oceanographic, climate, and instrumentation engineering research communities, with special attention to including early-career investigators, women, and underrepresented minorities. Attendees will be notified in September 2015.

The workshop is sponsored in part by SEARCH (Study of Environmental Arctic Change), CliC (Climate and Cryosphere) and GRISO (Greenland Ice Ocean Observing Network). Participants will be expected to cover their own travel to San Francisco (the workshop precedes the AGU Fall Meeting) but some funding will be available for the extra accommodation and meal costs.

Report Available: ESA-CliC Earth Observation and Arctic Science Priorities

ESA CliC group photoThe European Space Agency and the Climate and Cryosphere project are pleased to present the publication of “Earth Observation and Arctic Science Priorities”. This report resulted from several consultations with the cryosphere community including a workshop held in January at the Fram Centre in Tromsø, Norway. More information on the meeting, including presentations, can be found here: http://www.climate-cryosphere.org/meetings/past/2015a/esa-arctic-2015.

The outcome of the meeting and its conclusions will contribute to guide scientific activities on Arctic research, including ESA’s programmatic priorities for the time frame 2017-2021. Despite not covering all components of the Arctic cryosphere, discussions covered a fairly large spectrum of research areas where EO may contribute.

We thank the workshop participants and many others in the cryosphere community who contributed substantially to this report.

Antarctic Sea Ice Variability Workshop - Call for Nominations

-This is a CliC sponsored workshop

AcademiesOfScienceThe Polar Research Board (PRB) and the Ocean Studies Board (OSB) are pleased to announce a new National Academies of Sciences, Engineering and Medicine workshop on ‘Antarctic Sea Ice Variability in the Southern Climate-Ocean System’. This workshop is also sponsored by NASA, NSF, and ONR. It will assess current understanding of processes driving Antarctic sea ice changes--including controls on decadal-scale growth and recent surge in Antarctic sea ice extent, whether or not these changes remain within the expected range of natural climate variability, and why climate models continue to fail in simulating them. The full Statement of Task for the workshop is available here. A designated rapporteur will prepare a summary report that provides a record of workshop presentations and discussions; it will not include consensus findings or recommendations.

Nominations for membership on the ad hoc committee that the Academies will appoint to plan the workshop are being sought. The committee of approximately 5 members will organize the workshop and serve as session facilitations during the event. For the planning committee, people with expertise pertaining to: ocean and sea ice observations (in situ and remote sensing); Antarctic climate and oceanography; ocean, climate or sea ice modeling; process studies of the coupled sea ice - ice sheet - ocean - atmosphere system; prediction and attribution of Antarctic sea ice changes are encouraged to apply. Self-nominations are welcome.

You can submit your nominations via a web-form here (preferred), or send your nominations directly to Michael Hudson. If submitting nominations directly, send the person’s name, affiliation, contact information, area of expertise, and a brief statement on why the person’s expertise is relevant to the topic. The deadline for submissions is Thursday, August 17.

The workshop will likely be held in the first two weeks of January 2016.



ISMIP6 Workshop, August 19, 2015, in Cambridge, UK

-Contributed by Sophie Nowicki - ISMIP6 is a CliC sponsored activity

ismip6logo BWA workshop will be held in Cambridge, UK on Wednesday afternoon, 19 August 2015 from 2pm – 5:30 pm in Churchill College (Storey’s Way, Cambridge CB3 0DS, UK), during the free afternoon of the International Glaciological Society’s International Symposium on Contemporary Ice-Sheet Dynamics.

This meeting will focus on one of the components of ISMIP6: the standalone ice sheet models driven offline by surface climatic forcing from climate models. Past efforts, such as SeaRISE and ice2sea, have indicated that different methods for initialization of ice sheet models (interglacial spinup, assimilation of present day observations, or a combination of both) may play an important role in the spread in projection of ice sheet evolution, and thus may contribute to the uncertainty in projection of sea level. ISMIP6 is therefore designing an experiment that focuses on the initialization of ice sheet models.

The agenda for the meeting is:
- Presentation of the responses to the initialization questionnaire, with a particular focus on datasets being used.
- Discuss the current design of the experiment on initialization, which builds on the feedback received at the ISMIP6 Splinter meeting at EGU (April 2015).
- Identify synergies between ISMIP6 and ISMASS.  

The initialization questionnaire for ice sheet models has been send to the ISMIP6 mailing list, but can also be obtained here. It should be returned to Tony Payne ideally by 27 July 2015, so that your responses can be included in the workshop.
