Demonstration Schedule

NSIDC staff will demonstrate various tools and data products at our booth in the AGU exhibit hall. For more information about the demonstrations listed below, contact NSIDC User Services at or +1 303.492.6199.

The Antarctic Cryosphere Access Portal (A-CAP)
The Antarctic Cryosphere Access Portal (A-CAP) is a geo-visualization and data download tool developed by NSIDC researchers. A-CAP provides access to Antarctic Glaciological Data Center (AGDC) data and other Antarctic parameters including glaciology, ice core data, snow accumulation, satellite imagery, digital elevation models (DEMs), sea ice concentration, and many other cryosphere-related measurements.  During this demonstration, we will show users the basic functionalities of A-CAP, including locating data sets and viewing them in the map, saving maps, and downloading data.
December 15th 2:00 p.m. - 2:30 p.m. by Jennifer Bohlander
December 17th 1:30 p.m. - 2:00 p.m. by Katherine Leitzell

GLIMS Glacier Viewer
The Global Land Ice Measurements from Space (GLIMS) initiative, through collaboration with glaciologists around the world, is building a global geospatial database of glacier information, including complete digital outlines, elevation information, and other such data. The database currently contains information on 83,000 glaciers covering 262,000 km2, and stores metadata for 227,000 ASTER images over glacierized terrain.  These glacier data are accessible on the Web via two interfaces: an interactive map, and a text-based search interface. Data are downloadable in a choice of formats, including GIS shapefiles, GMT ASCII, and KML formats. In addition, we provide a Google Earth interface to browse ASTER image scenes, as well as Open Geospatial Consortium Web services (e.g. Web Map Service). This demo will describe the contents of the database and these interfaces.  Presented by Siri Jodha Singh Khalsa on:
December 15th 12:00 p.m. - 12:30 p.m.
December 16th 12:30 p.m. - 1:00 p.m.
December 17th 1:00 p.m. - 1:30 p.m.

Introducing the National Snow and Ice Data Center (NSIDC) SAGE Tool—for Data Discovery, Services and Analysis
Using the core architecture developed for NSIDC’s Searchlight product, NSIDC introduces SAGE (Services for the Analysis of the Greenland Environment). This new, on-line discovery and access interface retrieves data for Greenland providing end-users with real time analysis/plotting of that data. Built on top of the National Snow and Ice Data Center’s newly-developed Searchlight engine, the SAGE interface will have access to all of NSIDC’s relevant Greenland data holdings, including raster, point and vector data. Web services will provide the ability for other clients to utilize the functionality that SAGE will provide, extending the options available to scientists for easily accessing data and tools that will enable them to devote more time to research and less time to locating and processing data.
Presented by Dave Gallaher and Scott Lewis on:

Overview of the Exchange for Local Observations of the Arctic (ELOKA)
The Exchange for Local Observations of the Arctic (ELOKA) provides data management services and user support to facilitate the collection, preservation, exchange, and use of local observations and knowledge of the Arctic. ELOKA seeks to help make local and traditional knowledge (LTK) discoverable and useful to the communities themselves and to research scientists. This demo provides an overview of the ELOKA project and demonstrates how we are organizing and presenting video, photos, and maps from Saniqiluaq, Nunavut. We also present ideas and seek feedback on how this sort of information could be used in conjunction with conventional scientific data.

Introducing the NSIDC Advanced Data Search online tool for Discovery and
Access of Cryospheric Data
Come see a demo of the new, on-line discovery and access interface at the National Snow and Ice Data Center (NSIDC). NSIDC is changing our user access model from "Search and Order (and Wait and Download)" to "Discovery and Access." We are reducing the distance between our users and our data holdings, with our new infrastructure that supports users finding and browsing actual data holdings on-line.  No more waiting for FTP staging followed by lengthy research to open and view data, only to find that it's not what you wanted or expected.  Powered by the NSIDC Searchlight engine, our Beta release Advanced Data Search online tool delivers data downloads immediately, with the user in control of on-the-fly output reformatting, reprojection and subsetting. In this way, we are delivering only what the user wants, and how they want it.  The sooner our users can obtain what they want, in a format they can quickly understand and use, the more time they have to devote to their own scientific investigations.

Glacier Photograph Search & Order Interface Demo
NSIDC houses many photographic prints of glaciers, taken both from the air and from the ground. These photographs constitute an important historical record, as well as a data collection of interest to those studying the response of glaciers to climate change. NSIDC, in partnership with the NOAA Climate Database Modernization Programam (CDMP) and the National Geophysical Data Center (NGDC), is digitizing selected photographs and making them available through a searchable interface. To date, more than 11,000 photographs have been digitized and comprise the Glacier Photograph Collection. During this demonstration, we will show users how to use the Search & Order Interface to obtain glacier photographs.

December 16th  11:00 a.m. - 11:30 a.m.

Take a climate change tour of cold places in Google Earth
This narrated tour flies you to the polar regions in Google Earth where you can learn about changes that are occurring in these snowy and icy regions.  Scientists Ted Scambos and Julienne Stroeve answer questions from middle-school students about climate change and their responses are incorporated into the tour.  The focus is on sea ice, permafrost, glaciers and ice shelves.

Film Showing: International Geophysical Year, 1957 – 1958: Drifting Station Alpha
This film documents the activities that occurred on Drifting Station Alpha in the Arctic Ocean during the International Geophysical Year, 1957 to 1958. The film is narrated by project leader, Norbert Untersteiner, and chronicles the life of the team as they built their camp and set up experiments. Station Alpha was the first long-term scientific base on arctic pack ice operated by a Western country. At the time of its establishment, Russia had already operated six drifting ice camps of this kind. However, due to the strategic importance and sensitivity of the Arctic Basin, little information from these early stations had reached the West. The documentary was filmed and produced by Frans van der Hoeven (Senior Scientist at Station Alpha) and Norbert Untersteiner (Scientific Leader of Station Alpha). Station Alpha drifted in an area of the Arctic ocean located 500 km north of Barrow, Alaska USA from April 1957 to November 1958; the film covers this entire time period. Digitized copies of the film are available on DVD.
December 15th, 4:00 p.m.  Length is 33 minutes

Film Showing: Good Days on the Trail, 1938-1942: Film Footage of the Rocky Mountains, Colorado
This film documents student hiking trips conducted by the University of Colorado at Boulder in the Rocky Mountains, Colorado, USA during the summers of 1938-1942. The hikes took place in various locations west of Boulder, including Rocky Mountain National Park, Indian Peaks Wilderness, and Roosevelt National Forest. The film contains rare historical footage of the Rocky Mountains, including Arapaho Glacier and Fair Glacier. The film provides a unique record of what those areas looked like at that time, and may provide visual information on the extent of the glaciers. The film was created by the University of Colorado Department of Mountain Recreation and originally consisted of four reels, in 16mm Kodachrome format. The film was restored and digitized with support from the NOAA National Geophysical Data Center, Boulder, and the NOAA Climate Database Modernization Program. Digitized copies of the film are available on DVD.;
December 16th, 2:00 p.m. Length is 45 minutes

Film Showing: Arctic Ice Dynamics Joint Experiment (AIDJEX) Second Pilot Study, March to May 1972
The project described in this documentary was a pilot study conducted in 1972 in preparation for the AIDJEX main experiment of 1975 to 1976.  The study included a main camp on drifting sea ice in the Beaufort Sea north of Alaska along with two satellite camps forming a station triangle with a 100-kilometer side length.  The film was produced by Hannes Zell and Dieter Wittich of Vienna, Austria December 16th 11:30 a.m. Length is 52 minutes
