Glacier Researchers to Join March for Science Around the World

Spread the News:ShareLarge groups plan to assemble on April 22 in Washington, D.C. and cities across the world as part of the March for Science to demonstrate their support of science and the role of scientific evidence in guiding policy. Glacier researchers and other cryosphere specialists are preparing to join their colleagues from other disciplines in this global expression of concern. The March for Science has grown over a short period, the idea first emerging soon after the 2017 Women’s March in January. It quickly gathered momentum with large numbers of adherents on social media, drawing inspiration from the 2014 People’s Climate March. The organizers selected April 22, Earth Day, as the date for the events. By February, 27 scientific associations had joined as partner organizations to co-sponsor the march. To date, 107 organizations are sponsoring the event, with 429 satellite marches planned in 42 countries.   In addition to seeking to assure funding for scientific research, the march has a number of other goals: supporting scientific education, promoting diversity and inclusiveness in science, affirming science as a democratic value, and advancing the role of scientific evidence in policy-making.  Though some have voiced a concern that the march could serve those who seek to attack science, by politicizing science and presenting scientists as an interest group, the march’s supporters have argued for the urgency of taking a public stand in the face of unprecedented threats to scientific research and to the belief in science itself. One of the march’s earliest sponsors was the American Association for the Advancement of Science (AAAS), the world’s largest general scientific organization, with over 120,000 members. Agustin Fuentes of the University of Notre Dame, the chair-elect of the anthropology section of the AAAS, spoke recently with GlacierHub about the back and forth discussions across the membership when the idea first came up. “The leadership stood up right away and spoke publicly,” he said, adding  that this “galvanized the membership.”   Fuentes further underscored the importance of science at a time when, as he said, “the structure of the planet is changing so fast.” He continued, “We are at a point of almost no return. I never expected to see video footage of glaciers shrinking…We’ve known of this global disruption climatologically, and it’s been ramped up politically. People who engage in science have to speak up now.” He spoke as well of primates, the “canaries in coal mines for the world’s forests,” with over 60% of primate species listed as threatened. Robin Bell of Columbia University, the president-elect of the American Geophysical Union (AGU), linked cryosphere processes with the importance of the march. The AGU, with over 60,000 members, was one of the march’s first sponsors. “The march is a chance for us to talk about how science matters,” she said. “Science is important for society, and it’s non-partisan.”   “We’re still making basic discoveries about how ice sheets work,” Bell continued, referencing her own work in Antarctica. These findings are important to society because of “the linkage to sea level rise” and the threats to port facilities in the current economy, where “goods move all around the world.”  She emphasized that the march was global, with other countries besides the US needing to assure the role of science in policy and decision-making. Alisse Waterston,  the president of the American Anthropological Association (AAA), described to GlacierHub her organization’s path to supporting the march. At the AAA’s 2016 annual meeting in mid-November, less than two weeks after Election Day, members voiced their wish to take action. “It was remarkable to see such a strong sense of solidarity,...

A New View on Border Tensions between India and China

A New View on Border Tensions between India and China

Spread the News:ShareNumerous disputes exist in remote regions of the world where the terrain makes it difficult to secure and manage borders. One well-known example is the Sino-Indian border in the Himalayas. Known as the Line of Actual Control (LAC), this line demarcating the frontier between Indian and Chinese-controlled territory is the longest disputed land border in the world. Natural, human and technological issues complicate the management of this disputed border, as explained by Iskander Rehman in a paper published in the most recent issue of the Naval War College Review. The entire Sino-Indian border is 4056 km in length, with disputed areas found in Aksai Chin in the western part of the border and in Arunachal Pradesh in the eastern area. The disputed border in Arunachal Pradesh is sometimes referred to as the McMahon Line, which Britain and Tibet agreed to in 1914, but which has never been acknowledged by China. Both of these areas were taken over by the Chinese in the Sino-Indian war in 1962, and the two countries have remained in an uneasy coexistence since then. インド軍と中.国人民解放軍が国境付近でにらみ合い。緊張状態が続いています pic.twitter.com/0rPhVOnMpz — ボケて(秀逸) (@bokete_hot) March 6, 2017 This tweet from Japan offers a humorous take on the long standing border issue between the two countries, saying “The Indian Army and the China People’s Liberation Army intersect near the border. Tension is continuing.” Several factors have influenced the dynamics of the border dispute since 1962, as highlighted by Rehman. Three relate to military activities: India has a greater military presence along the disputed areas of the LAC, while China possesses better communications infrastructure and a more unified command structure. The fourth arises from the climate and terrain in the disputed regions. Due to the remoteness and large expanse of the Himalayas, multiple land border disputes are located within the mountain range. These can involve control of the region’s features, such as glaciers. For example, India and Pakistan have been involved in a stand-off over the Siachen Glacier in Karakoram in the northwestern part of the Himalayas since 1984. In the case of the Sino-Indian border disputes, the climate and terrain can confer strategic advantages, while creating challenges for both sides. Rehman argues that the high elevations of the Tibetan Plateau create advantages for the Chinese in terms of surveillance and the execution of artillery operations, while allowing troops stationed there to acclimatize to high-altitude warfare. Thick layers of frost and ice can also render regions of Aksai Chin more passable for heavy vehicles in winter, aiding the movement of troops and equipment.  However, other mountain passes can become inaccessible during harsh winters, and steep slopes contribute to regular landslides in Arunachal Pradesh, disrupting traffic. The highly unpredictable climate of mountainous terrain also makes military operations much more difficult, with extreme changes in the weather creating problems for troops and equipment. The effects of these difficulties are all too evident in the dispute between India and Pakistan, with the vast majority of casualties on both sides attributed to exposure, frostbite and avalanches, according to Rehman. Although hostilities ceased after 1962, and signs of Sino-Indian rapprochement emerged in the late 1970s, the issue of ‘gray-zone aggression’ (tactics adopted by revisionist powers that are coercive but do not cross established international red-lines) has created concern in India. Rehman highlights the fact that India is particularly troubled by China’s use of infrastructure development to cement claims over contested territory. Construction is often undertaken during seasons when snow makes areas inaccessible to India’s military, increasing tension along the border. The Indian military is often unable to detect these in a timely manner, allowing the Chinese...

These satellites joined dozens already in orbit, bringing the constellation of ‘Doves,’ as these tiny imaging satellites are known, to 144. Six months from now, once the Doves have settled into their prescribed orbits, the company says it will have reached its primary goal: being able to image every point on Earth’s landmass at intervals of 24 hours or less, at resolutions as high as 3.7 meters— good enough to single out large trees. Data from Planet is even enabling the monitoring of glaciers.” Read more about this work here.   Glacier Safety Awareness in Pakistan From Pamir Times: “Mountaineers and researchers from Shimshal Valley trekked across northeastern Pakistan this January, to raise awareness about saving glaciers from a warmer environment. Pakistan is home to the world’s largest glaciers outside of the polar region. The expedition was aimed at monitoring and collecting data to analyze the change in the glaciers due to global warming. The activists hope to inspire people at every level around the world, and Pakistan in particular, to stand up and take some substantial steps in addressing the issues of global warming and climate change.” Read more about the expedition here.   Spread the...

Photo Friday: New Zealand’s Glacier Retreat from Space

Spread the News:ShareA newly released ASTER image from January 29, 2017 shows the rapid retreat of New Zealand’s glaciers. When the image is compared to a Landsat image from January 12, 1990, differences can be detected between the larger terminal lakes and the ice free of moraine cover for the Mueller, Hooker and Tasman Glaciers. In total, New Zealand contains over 3,000 glaciers, many located on the South Island in the Southern Alps, according to NASA. These glaciers have been in retreat since 1890, with only short periods of recorded advance during that time. ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer), built by Japan’s Ministry of Economy, Trade and Industry, is one tool launched in 1999, along with four other Earth-observing instruments, used to monitor the changing surface of the planet. It allows scientists to better understand dynamic conditions, such as glacial advance or retreat, that are otherwise difficult to physically measure, and offers data critical for surface mapping.

Glaciers, Geoheritage and Geotourism

Glaciers, Geoheritage and Geotourism

Spread the News:ShareThe Valais in southern Switzerland is a mountainous canton that draws tourists each year for its spectacular scenery, including some of the largest glaciers in the central Alps. From a recent article written by Emmanual Reynard in Geoheritage and Geotourism, we learn that more than half of the canton’s workforce are employed by the tourism sector. Valais has long been a tourist hub in Switzerland, attracting sightseers and skiers to the two alpine ranges that lie on either side of the canton. This landscape played an important role in European art and literature, and Valais is also known as a key site for the development of glaciology. Tourists venture to the province not only for a glimpse of frosted peaks such as the famous Matterhorn and Weisshorn, but also to engage with the canton’s long history of geotourism and geoheritage which dates back to the 1800s.  The word geoheritage originates from the term “geological heritage,” and is defined by the diversity of geological features within a region. The Geological Society of America (GSA) applies the term to scientifically and educationally significant sites or areas with geologic features such as distinctive rocks, minerals and landforms. Geotourism is the exploration of such places. Sarah Strauss, an anthropologist at the University of Wyoming, has conducted extensive research in the Valais region. She believes that geoheritage is “very similar to landscape and a sense of place that is specific to the geologic rather than the broader environmental context.” Moreover, geoheritage is valuable because it permits geotourism. Canton Valais’s long history with tourism has reinforced its status as a geotourism hot-spot as climbers and hikers come to experience this glacial history for themselves.   As the GSA explains, “geological sites are critical to advancing knowledge about natural hazards, groundwater supply, soil processes, climate and environmental changes, evolution of life, mineral and energy supplies, and other aspects of the nature and history of Earth.” These sites should be protected and cherished for their natural beauty and importance. The tourism industry in Valais continues to celebrate its geoheritage through geotourism. The complex geology of Valais— the result of uplift and compression when the Alps first formed 20 to 40 million years ago— has made it a site of geoheritage throughout the centuries. Today, tourists and hikers can view crystalline and carbonate rocks formed millions of years ago on trails rising 800 to over 4,200 meters in elevation. Moreover, the region contains glacial valleys and horn peaks, as well as moraines, the masses of dirt and rocks deposited by glaciers. The Aletsch region of Valais is a UNESCO World Heritage site and is heralded as a site of outstanding natural and cultural importance. This region makes up the most glaciated part of the High Alps along with Jungfrau and Bietschhorn. The Aletsch is also home to the largest glacier in Europe. “While the Matterhorn is impressive, the Aletsch region is equally remarkable,” Strauss recalled to GlacierHub. “There were chapels and hotels built at the tongue of the glaciers.” Tourists that journey to Canton Valais will not be disappointed by the geologically significant province which embraces its geoheritage wholeheartedly. If you are unable to make the journey to Switzerland any time soon, enjoy pictures from the Valais tourism website here. Spread the...

New Research Offers Fresh Insight into the Iceman’s Death

New Research Offers Fresh Insight into the Iceman’s Death

Spread the News:ShareÖtzi, also known as the Iceman, is showing new signs of life – in his gut. Gabriele Andrea Lugli and other researchers from the University of Parma recently published findings on the Iceman in Microbiome Journal. Their research analyzes samples taken from Ötzi’s gut in order to reconstruct and characterize ancient bacteria to provide clues on how bacteria may have affected humans. While some evidence suggests that the Iceman was murdered or died from the lingering effects of an attack, researchers have now uncovered a new possible cause of death: inflammatory bowel disease. Ötzi was originally found in a receding glacier by two tourists in the Italian Alps in 1991. First thought to be someone from more recent times, research has shown that he lived about 5,300 years ago. Since then, he has become the best known frozen mummy in the world, because his remains are remarkably intact and offer a clear view of the distant past. Though Ötzi’s skin looks like brown caramel and his bones can be seen through his skin, he is very well preserved. Last year, PBS released a documentary titled “Iceman Reborn” about artist Gary Staab, who made a replica of the Iceman using 3D printing. One researcher in the film remarked, “He may well be the most studied human being in history.” Another researcher, referring to new discoveries about Ötzi’s genetic code, noted, “We are rewriting the history of humankind.” It was recently discovered that the Iceman has 61 tattoos, up from a previously smaller number. Ötzi’s tattoos are in locations where there is joint and spinal degradation, indicating the tattoos may have been treatment of some kind. In addition, he was found with a gash on his left hand and an arrow wound in his back, suggesting that he was murdered. He was also found with a copper axe, showing researchers that metalworking was earlier than previously thought. From the Archives: CT scans of ancient mummies show high levels of atherosclerosis, a condition associated with modern risk factors like smoking, obesity, and lack of exercise. Researchers think they know why the ancients also suffered from the disease. archaeology.org/news #archaeology #mummy #Otzi #heart (© Samadelli Marco/EURAC) A post shared by Archaeology Magazine (@archaeologymagazine) on Jan 27, 2017 at 9:54am PST While climate conditions can alter bacterial communities, low temperatures such as permafrost are optimal for long-term DNA preservation. Using a technique called next generation sequencing, the researchers investigated the human gut microbiota in the soft tissue of the human mummy. The samples yielded an enormous amount of data– about 71 gigabases from 12 biopsy samples. Ancient bacteria, such as the ones found in Ötzi’s gut, can provide clues on the history of diseases, the evolution of bacteria and bacterial infections in humans, allowing scientists to reconstruct pathogens like the plague (Yersinia pestis), leprosy (Mycobacterium leprae) and stomach infections (Helicobacter pylori). The researchers found that the upper part of the large intestines had ample Pseudomonas species. These bacteria are typically found in the soil. The presence of P. fluorescens in Ötzi’s intestines suggests that his immune system may have been compromised and that he may have been ill with inflammatory bowel disease at the time of his death. Other findings included the fact that even though modern P. veronii have been isolated from water springs, the ancient strain seems to have the ability to colonize the human gut. The bacteria also shares genetic material with Pseudomonas strains in isolated parts of Antarctica, a fact which supports its ancient origin. Evidence suggests that the evolution of the bacteria was helped by the development of its virulence....
