  1. Data Sets Available
    RADARSAT Continental Mosaics and High-Resolution Tiles of Antarctica
    from 1997 and 2000
    Polar Data Catalogue

Editors of the Polar Data Catalogues announce that the RADARSAT
continental mosaics and high-resolution tiles of Antarctica from 1997
and 2000 are available online.

These images have been converted into updated, more easily accessible
formats (GeoTiff) and can be compared to the 2008 Antarctic mosaics from
RADARSAT-2 which were released on the PDC in 2014. All three datasets
can be found under the "RADARSAT Mosaics of Antarctica" collection in
the PDC, and all imagery can be freely downloaded.

The RADARSAT-1 Antarctic Mapping Project (RAMP) and RADARSAT-2
Antarctic Mapping Initiative were undertaken to provide snapshots
of the Antarctic continent over a span of more than a decade, to
document the state of the ice cover in Antarctica and to show
changes over time in the land and sea ice around the southern
continent. RAMP was a collaboration between the Canadian Space
Agency and the U.S. National Aeronautics and Space Administration
(NASA) to map Antarctica using the RADARSAT-1 Synthetic Aperture
Radar (SAR) in two missions. The first, the Antarctic Mapping
Mission 1 (AMM-1), completed in September-October 1997,
maneuvered the RADARSAT-1 satellite to a left-looking "Antarctic
Mode" to capture the entirety of the continent, developing the
first high-resolution SAR mosaic of Antarctica. The second, the
Modified Antarctic Mapping Mission (MAMM), completed in
September-November 2000, captured imagery north of 80 degrees S
all the way to the Antarctic coast, in both ascending and descending
orbits. The objective of this mission was to observe changes in the
ice sheet from the 1997 AMM-1 dataset and to use the multiple acquisitions
to estimate the surface velocity of target areas of the ice sheet.

The RADARSAT-2 Antarctic Mapping Initiative, completed in October
-December 2008, was undertaken to produce a continental mosaic consistent
with the 1997 RADARSAT-1 Antarctic Mapping Mission. The resulting mosaics
and individual high-resolution tiles, produced in collaboration with the
Byrd Polar Research Center, cover all the way to the South Pole, repeating
the coverage of the 1997 mission. In addition to enhancing the achievements
of the RADARSAT-1 Antarctic missions, the intent of the 2008 mission was to
facilitate change analysis through space-borne observation of ice sheets.
Such data are important for generation of global climate products, including
models. The 2008 mission was the result of international collaboration associated
with the International Polar Year (IPY) and is a Canadian Space Agency contribution
to IPY, incorporating input from the scientific community, with the goal of
making science products available for free.

  1. New Book Available
    "Ice Bear: The Cultural History of an Arctic Icon"
    By Michael Engelhard
    University of Washington Press

The University of Washington Press has released a new book by Michael
Engelhard entitled "Ice Bear: The Cultural History of an Arctic Icon."

"Ice Bear" traces and illuminates the intertwined history of the polar
bear as a source of wonder, terror, and fascination. Eight thousand
years of artifacts attest to its charisma, and to the fraught
relationships between our two species. With research and more than 160
illustrations, the author brings into focus this powerful and elusive
animal. Doing so, he delves into the stories we tell about Nature-and
about ourselves-hoping for a future in which such tales still matter.
