For more information about requesting ice drilling support, please
visit: http://www.icedrill.org/scientists/scientists.shtml.

For information and ideas about partnering with the Ice Drilling Program Office for broader impacts, please visit: http://www.icedrill.org/scientists/outreach_support.shtml.

Deadline: Wednesday, 9 January 2013 for Nominations Workshop Committee Opportunities to Use Remote Sensing in Understanding Permafrost and Ecosystems U.S. National Research Council

The National Research Council (NRC) announces a call for nominations, seeking members for an ad hoc committee that will organize a new NRC activity, "Opportunities to Use Remote Sensing in Understanding Permafrost and Ecosystems: A Workshop."

A committee of experts will plan the workshop to explore opportunities for using remote sensing to advance our understanding of permafrost status and trends and the impacts of permafrost change, especially on ecosystems and the carbon cycle in the high latitudes. The workshop discussions will be designed to encourage attendees to articulate gaps in current understanding and potential opportunities to harness remote sensing techniques to better understand permafrost, permafrost change, and implications for ecosystems in permafrost areas. The committee will write a report that summarizes the workshop discussions.

The committee of 8-9 members will meet numerous times by conference call to plan the workshop structure, identify appropriate speakers and attendees, and develop background materials for attendees. Committee members will lead the workshop and serve as session facilitators. The committee will remain for an extra day after the public workshop to summarize the discussions and begin preparing the workshop report.

The committee will need expertise in a range of areas: permafrost, high latitude ecosystems, remote sensing technologies (e.g., LIDAR, hyperspectral, optical, radar, InSAR, thermal infrared, airborne resistivity), climate change, hydrology, vegetation, geomorphology, and snow science. To submit a nomination, please email Rob Greenway (rgreenway@nas.edu) with the person's name, affiliation, contact information, area of expertise, and a brief statement on why the person is relevant to the study topic.

Discussion on Arctic climate change at COP 18

On December 6 in Doha, as the COP 18 climate change negotiations switched gears for the finale, the Swedish Chairmanship of the Arctic Council arranged a side event on climate change in the Arctic. The event was held against the background of the rapid and ominous development lately in the Arctic, in particular the past summer's sea ice melt. The event was well attended and a strong panel including Martin Lidegaard, climate and energy minister of Denmark, Jens Fredriksen, Minister for housing, infrastructure and transport from Greenland, and Lena Ek, Swedish Minister for the Environment, contributed to a lively discussion.

    Release of the Javascript Ice Sheet Model

    The Javascript Ice Sheet Model (J-ISM) is a browser-based ice sheet model for educational purposes. The model is based on Frank Pattyn's Excel-based GRANTISM, and thus behaves more or less identically to that model.

    The model is available to play with online at http://mewo2.com/ism.html
    and the code is on GitHub at https://github.com/mewo2/j-ism

    The model has been tested on undergrads by Martin O'Leary, Research Officer at the Department of Geography, Swansea University. The instructions he gave the students (3rd year geography undergrads) are accessible at
    http://mewo2.com/assets/model.pdf and http://mewo2.com/assets/practical.pdf
    Martin O'Leary welcomes comments, issues and bugfixes, please e-mail to: m.e.w.oleary@gmail.com

    “State of the Earth

    A Cold Look at Planet Earth: Learning from the World’s Frozen Places
    The recently published State of the Earth’s Cryosphere at the Beginning of the 21st Century summarizes past and present-day changes in the Earth’s cryosphere (the whole of its frozen water) and describes the ongoing and potential effects of those changes. Extensively illustrated in print and connected to a companion online image gallery, this volume supplies a synthesis for 10 other geographically-based volumes in the 11-volume Satellite Image Atlas of Glaciers of the World.

    Palaeoenvironments and palaeoceanography changes across the Jurassic/Cretaceous boundary in the Arctic realm: case study of the Nordvik section (north Siberia, Russia)

    The Jurassic/Cretaceous transition was accompanied by significant changes in palaeoceanography and palaeoenvironments in the Tethyan Realm, but outside the Tethys such data are very scarce. Here we present results of a study of the most complete section in the Panboreal Superrealm, the Nordvik section. Belemnite δ18O data show an irregular decrease from values reaching up to +1.6‰ in the Middle Oxfordian and from +0.8 to −1.7‰ in the basal Ryazanian, indicating a prolonged warming. The biodiversity changes were strongly related to sea-level oscillations, showing a relatively low belemnite and high ammonite diversity during sea-level rise, accompanied by a decrease of the macrobenthos taxonomical richness. The most prominent sea-level rise is marked by the occurrence of open sea ammonites with Pacific affinities. Peak abundances of spores and prasinophytes correlate with a negative excursion in organic carbon δ13C near the J/K boundary and could reflect blooms of green algae caused by disturbance of the marine ecosystem.
