Photo Friday: Tibetan Plateau From Space

Spread the News:Share55 million years ago, a major collision took place between two of the large blocks that form the Earth’s crust. The Indian Plate pushed into the Eurasian Plate, creating what is known as the Tibetan Plateau. The region, also known as the “Third Pole,” spans a million square miles and contains the largest amount of glacier ice outside of the poles. A photograph of the southern Tibetan Plateau taken from space was released June 17th, showing the dramatic topography in false color. The photograph, taken by the Sentinel-2A, was captured near Nepal and Sikkim, a northern state of India, on February 1st. According to the European Space Agency (ESA), “From their vantage point 800 km high, satellites can monitor changes in glacier mass, melting and other effects that climate change has on our planet.” This week, enjoy stunning satellite pictures of the Tibetan Plateau over time. NASA also has taken photographs of the same plate collision from space, showing the snow-capped Himalayas, which are still rising. A true-color image of the Tibetan Plateau, taken in 2003 by NASA’S MODIS Rapid Response Team, shows the region’s lakes as dark patches against the sand-colored mountains. Prior to the true-color photograph, a spaceborne radar image of the Himalayan Mountains was taken in 1994 in southeast Tibet. Each color is assigned to a different radar frequency that depends of the direction that the radar was transmitted. Spread the...

Photo Friday: Volcanoes of the Kamchatka Peninsula

Spread the News:ShareThe Kamchatka Peninsula, located in remote Far East Russia, is part of the “Ring of Fire” and is known for its volcanic activity. The 102,400 square mile region has the highest concentration of active volcanoes in the world. The Klyuchevskoy volcano is one of the seven active glacier-capped volcanoes in the remote region. At a towering 4,835 meters, the Klyuchevskoy, the area’s tallest volcano, is known for its beauty and symmetry. Considered Kamchatka’s most active volcano, Klyuchevskoy has the likely potential to erupt and is currently listed as code orange. The volcano’s current lava flows still are no match for the 1994 eruption, which sent volcanic ash nine miles high into the atmosphere. Over the past three decades, satellites have captured many eruptions within the Kamchatka Peninsula, like the 1994 eruption of Klyuchevskoy, seen here. In January of 2013, four volcanoes—Shiveluch, Bezymianny, Tolbachik, and Kizimen — erupted at the same time. In 2010 a unique photograph of the region was taken from the International Space Station, providing a unique perspective of the glacier-capped volcanoes. Spread the...

Roundup: Glacial Melt, Photos, and Disasters

Spread the News:ShareEach week, we highlight three stories from the forefront of glacier news. The Climate Post: Melting of Totten Glacier Could Trigger 6 Foot Sea-Level Rise From Huffpost Green: “A new study published in the journal Nature is drawing attention to the effect of warming water on the world’s largest ice mass, Totten Glacier in East Antarctica. Melting of the glacier, which has an ice catchment area bigger than California, could lift oceans at least two meters (6.56 feet). According to researchers who mapped the shape of the ice sheet as well as the thickness of rocks and sediments beneath it to examine the historical characteristic of erosion of Totten’s advances and retreats, unabated climate change could cause the glacier to enter an irreversible and rapid retreat within the next century.” Find out about Totten Glacier’s “tipping point.”   Spectacular view of fjord and glacier from NASA’s IceBridge From Zee Media Bureau: “New Delhi: NASA’s IceBridge, an airborne survey of polar ice, recently captured this stunning view of fjord of Violin Glacier, with Nord Glacier at the upper left corner.  IceBridge took this image on May 16, 2016 as the aircraft crossed Greenland to fly central glacier flowlines in the east-central region of the country. This year marks IceBridge’s eighth spring campaign of science flights over Arctic sea and land.” Learn more about NASA’s IceBridge campaign here.   Report Warns of Climate Change Disasters That Rival Hollywood’s From the New York Times: “Stonehenge eroding under the forces of extreme weather. Venice slowly collapsing into its canals. The Statue of Liberty. gradually flooding. Images like these, familiar from Hollywood climate-catastrophe thrillers, were evoked by a joint report, released on Thursday by Unesco, the United Nations Environment Program and the Union of Concerned Scientists, that detailed the threat climate change could pose to World Heritage sites on five continents.” To learn more about the potential impact of glacial melt induced-sea level rise on some of the world’s most iconic heritage sites, click here.

Photo Friday: NASA’s Operation IceBridge

Spread the News:ShareNASA’s Goddard Space Flight Center’s ongoing operation called IceBridge uses manned aircraft to study polar ice. IceBridge serves to bridge the gap between NASA’s Ice, Cloud and Land Elevation Satellite (ICESat), which stopped collecting data in 2009, and NASA’s second generation of the satellite (ICESat-2) which is scheduled to launch later this year. The six year operation is the largest airborne survey of  Earth’s polar ice, and collects data about ice sheets, ice shelves, and sea ice in Greenland and the Antarctic. The goal is to document annual changes in thickness of sea ice, glaciers, and ice sheets along with collecting information to help with the modeling the effect of climate change on Earth’s polar ice, specifically in connection to possible sea-level rise. IceBridge Airplanes fly over Greenland between March and May and in  over Antarctica between October and November. Smaller airplane surveys of ice around the world are also included in the IceBridge operation.       Pic from today's #IceBridge flight: Network of supraglacial meltwater drainage channels. pic.twitter.com/hlUvPQky5y — NASA ICE (@NASA_ICE) May 18, 2016   Spread the...

Photo Friday: Upsala Glacier

Spread the News:ShareUpsala Glacier, a stunning glacier within Parque Nacional Los Glaciares in Argentina, has been retreating rapidly due to climate change. NASA has found, through satellite imaging, that Upsala’s ice front has moved back approximately 2 miles since 2001, following a similar trend seen in the rest of Patagonia (the vast area at the southern extent of Chile and Argentina). Also featured in the photos below is the Estancia Cristina–a popular ranch that many visitors use as an outpost on their journey through the glacial park, especially to see Upsala. The ranch offers unique views of the glaciers and its own beautiful scenery. Upsala gets its namesake from the Swedish University (Uppsala University) that first sponsored glacier research in this area. The area has been extensively studied since, and Upsala is often used as an example of glacial retreat in Argentina. Upsala’s retreat is significant because of the size of the glacier; once the largest glacier in South America, it is now the third largest. Argentinian glaciers, and Upsala in general, will aid in our further understanding of glacier dynamics.
