An Inspirational Lecture Delivered by Dr. Ted Scambos of NSIDC

TAINAN, Taiwan--(Business Wire)--
Dr. Ted Scambos, the Lead Scientist of the USA National Snow and Ice Data Center
(NSIDC) was invited by National Cheng Kung University (NCKU) to deliver an
inspirational lecture on May 20, entitled "A closer look at polar ice:
Formosat-2 and glacier changes in the Arctic and Antarctic." The research team,
led by Dr. Scambos, has been collaborating with NCKU faculty on the acquisition
of satellite images from Formosat-2, an Earth observation satellite operated by
Taiwan`s National Space Organization (NSPO).

During the lecture, Dr. Scambos showed superior and high-resolution digital
multi-spectral images of both the Antarctica and the Arctic, which were acquired
from Formosat-2 satellite, to explain the relation between climate change, and
disintegration and retreat of ice shelves.

Dr. Scambos is really concerned about the disappearance of permafrost owing to
global warming, leading to significant emission of greenhouse gases entrapped
underneath, such as methane and carbon dioxide, which, in turn, would accelerate
pace of global warming and, hence, threaten the lives of human beings. Measures
and actions to slow down and, even, to sop the pace of global warming are in
urgent needs.

Dr. Scambos indicated that flowing water from fracture of ice shelf will deepen
the fracture, eventually resulting in the cracking of ice shelf and glacier. In
addition, liquid water in the cracks can drill to the base of an ice shelf, and
leading to its disintegration piece by piece. During his lecture, Dr. Scambos
revealed the details regarding the break-up of the Wilkins Ice Shelf on the
Antarctic Peninsula, and explained the importance of ice shelves. He said that
the break-up of ice shelves can accelerate the sea-level rise. "Ice shelf is the
key one to keep the glacier stable and the glacier up the level," added by Dr.
Scambos.

Moreover, Dr. Scambos also gave a warning resulted from the rapid break-up of
the Arctic sea ice. According to Dr. Scambos, the ice layer covering the Arctic
can reflect the solar heat back to the space; however, the open seas uncovered
by the ice will absorb more solar heat, worsening the situation in global
warming. One of the impacts pondered by this phenomenon is that the drought on
earth occurs more frequently with an expanding arid area.

Dr. Scambos concluded that the break-up of ice shelves and warm ocean water will
result in rapid collapse of glaciers, both of which are highly correlated to
severe global climate change.

The lecture by Dr. Scambos has triggered the audience`s curiosity and inspired
the audience to raise many interesting questions regarding Antarctica and the
Arctic, including the temporary disappearance of the polar ice and its
consequence on global climate change. Dr. Scambos pointed out that Arctic sea
ice will disappear for a few weeks in summer over the region around the North
Pole extending towards Russia by sometime between 2020 and 2030. The open water
in late summer, and the delayed formation of an ice layer over the ocean in
winter, will begin to have an effect on climate in the surrounding permafrost
regions at first and later, generally, in the northern hemisphere (later),
especially in early autumn and winter. In fact we can already observe the
beginnings of these changes in climate. Dr. Scambos called on more emergent
steps to curb the pace of global warming to ensure the life safety of human
beings.

Two years ago, the former Vice President of United States, Al Gore, testified
before the Congress on climate change and the data he used on collapse of
Wilkins ice shelf was indeed based on the outstanding digital images requested
from Formosat-2 imagery for polar research, the joint collaboration project with
NCKU.

During the lecture, Dr. Ted Scambos showed the audience four areas of interest
for which Formosat-2 imagery has provided very important data: the
disintegration of Antarctic Peninsula`s Wilkins Ice Shelf during February-March,
2008; the Ward Hunt Ice Shelf retreat in July-August 2008 in the Arctic coast of
Ellesmere Island; glacial velocity mapping from Formosat-2 image pairs for
Kangerlugssuaq Glacier in southeastern Greenland during the summer of 2008; and
velocity mapping for the central Crane Glacier in the Larsen B region of the
Antarctic Peninsula spanning the period February 2008 to March 2009.

About Dr. Ted Scambos

Dr. Ted Scambos received his master's degree from Virginia Tech and his PhD in
Geology from the University of Colorado at Boulder. His interest in satellite
data began when he used Landsat imagery for his PhD dissertation. He worked with
NASA at the Goddard Space Flight Center, studying Antarctica using satellite
data. Ted's specialties include glaciology and remote sensing; geochemistry and
planetary science.

Now as a Lead Scientist at NSIDC, Ted has conducted 9 field studies of the West
Antarctic ice sheet and its sea ice, and several remote sensing of West
Antarctic ice shelves with colleagues Dr. Christina Hulbe of Portland State
University and Dr. Mark Fahnestock of the University of Maryland. His polar
remote sensing research concentrates on visible and near-IR remote sensing
(MODIS, Landsat 7, IKONOS), ICESat laser elevations, field GPS, and ice
profiling radar studies. Recent work has taken him from unique large dune
features in the center of the East Antarctic Plateau ('megadunes') to the
icebergs off the shore of the Antarctic Peninsula and south of Argentina. He was
part of an international team that landed on an Antarctic iceberg via helicopter
to set up observational instruments for detecting changes as the iceberg drifts
north and begins to melt; see http://nsidc.org/icetrek for more information.

About National Snow and Ice Data Center

The National Snow and Ice Data Center (NSIDC) is part of the Cooperative
Institute for Research in Environmental Sciences at the University of Colorado
at Boulder. NSIDC supports research into our world's frozen realms: the snow,
ice, glaciers, frozen ground, and climate interactions that make up Earth's
cryosphere. Scientific data, whether taken in the field or relayed from
satellites orbiting Earth, form the foundation for the scientific research that
informs the world about our planet and our climate systems.

NSIDC manages and distributes scientific data, creates tools for data access,
supports data users, performs scientific research, and educates the public about
the cryosphere.
