Roundup: Ice Filing, Seas Falling, Rivers Flooding

Spread the News:ShareThis Week’s Roundup: Glaciers are being collected in Antarctica, “quietly transforming the Earth’s surface” and causing floods A team of scientists, aware of the need to obtain ice cores from threatened glaciers, are working to create a glacier archive bank in Antarctica From CNRS News:  “By capturing various components of the atmosphere, ice constitutes an invaluable source of information with which to examine our past environment, to analyze climate change, and, above all, to understand our future. Today, the science of ice cores lets us study dozens of chemical components trapped in ice, such as gases, acids, heavy metals, radioactivity, and water isotopes, to name but a few…” “We plan to store the boxes in containers at a depth of 10 meters below the surface in order to maintain the glacier cores at an ambient temperature of – 54°C. The Antarctic is in fact an immense freezer with an ice sheet up to 4 kilometers thick, and is far removed from everything; in addition, it is not subject to any territorial disputes. The subterranean chamber will be large enough to house samples taken from between 15 and 20 glaciers.” Read on here.  Study finds that ancient melting glaciers are causing sea levels to drop in some places From Smithsonian Magazine: “But a new study out in the Journal of Geophysical Research shows that in places like Juneau, Alaska, the opposite is happening: sea levels are dropping about half an inch every year. How could this be? The answer lies in a phenomenon of melting glaciers and seesawing weight across the earth called ‘glacial isostatic adjustment.’ You may not know it, but the Last Ice Age is still quietly transforming the Earth’s surface and affecting everything from the length of our days to the topography of our countries.” For the full story, click here. Glacial flood emerges along Iceland’s Skaftá river From Iceland Magazine: “A small glacial flood is under way in Skaftá river in South Iceland. The Icelandic Met Office (IMO) warns travelers to stay away from the edge of the water as the flood water is carrying with it geothermal gases which can be dangerous….The discharge of Skaftá at Sveinstindur is presently 270 cubic metres per second. The flood is not expected to cause any downstream disruption.” Learn more about the flood by reading more here.         Spread the...

Iceland’s fire decimates its ice: Eyjafjallajökull

Spread the News:ShareA new scientific study investigates the interactions between the Icelandic volcano Eyjafjallajökull’s lava flow and the overlaying ice cap, revealing previously unknown subglacial lava-ice interactions. Six years after  the eruption, the volcano is revisited by the author of the study, Björn Oddsson, a geophysicist with Iceland’s Department of Civil Protection and Emergency Management. He and his team present the most up-to-date chronology of the events, reverse engineer the heat transfer processes involved, and discover a phenomenon which may invalidate previous studies of “prehistoric subglacial lava fields.” Eyjafjallajökull (‘jökull’ is Icelandic for ‘glacier’) hit headlines in April 2010, as it spewed 250 million tonnes of ash into the atmosphere. The explosive event shook the West, as it took an unprecedented toll on trans-Atlantic and European travel, disrupting the journeys of an estimated 10 million passengers. It is only known to have erupted four times in the last two millennia. The first hint that something major was about to happen in 2010 came as a nearby fissure — Fimmvörðuhálsa — to the northeast, began spouting lava in March and April 2010. Just as Fimmvörðuhálsa quieted, a “swarm of earthquakes” rocked the Eyjafjalla range, on April 13. The next day, Eyjafjallajökull started its 39-day eruption. Over four and a half billion cubic feet (130 million m3) of ice was liquefied and vaporized as six billion gallons of lava spewed forth from Iceland’s Eyjafjallajökull stratovolcano. Flowing at distances up to 1,640 feet (500 m) each day, the lava poured down the northern slopes of the Eyjafjalla range, nearly halving the mass of the glacier Gígjökull, as it bored a channel underneath the ice. Oddsson and co-authors Eyjólfur Magnússon and Magnus Gudmundsson have been on the leading edge of Eyjafjallajökull research, developing a comprehensive chronology of the subglacial processes at work in 2010. To complement their timeline, they developed a model demonstrating the probable interactions and volumes involved. The eruption was exceptionally well-documented and studied in real-time by the world-class volcanologists and glaciologists who populate Iceland. Oddsson’s et al. paper relied on a previously uncombined series of datasets (i.e. synthetic aperture radar (SAR), tephra sampling, seismic readings, webcam footage) to develop an holistic model to explain the subglacial formation of the 3.2 km lava field. In April 2010, magma began to rise to the surface — the “culmination of 18 years of intermittent volcanic unrest,” according to Freysteinn Sigmundsson and colleagues. The first outflow of lava rapidly began undermining the base layers of the Eyjafjallajökull ice cap, which was then around 656 ft (200 m) thick. Over two billion gallons of meltwater was generated. Dammed by the surrounding glacier and rock, the water pooled within the caldera (a large cauldron-shaped volcanic crater). There, it was rapidly heated, building up the subglacial pressure under Eyjafjallajökull’s ice cap over two hours — mimicking a pressure cooker. In the early hours of April 14, a “white eruption plume” broke through the overlying ice, ultimately ascending 3.1-6.2 (5-10 km) into the atmosphere. During the first three days of the eruption, a series of vast floods — “hyperconcentrated jökulhlaup[s]” — pulsed from under Gígjökull. The first jökulhlaup completely evacuated within half an hour, at up to 1.45 million gallons (5,500 m3) per second, according to Eyjólfur Magnússon of the University of Iceland. The outpouring of this vast volume was the first indication of an enormous transfer of energy taking place beneath the Eyjafjallajökull ice cap. Oddsson and his team determined that over 45 percent of the heat from the eruption was expended melting the ice, based on inferences of the outflowing steam, tephra, water, and other materials....

Nature Meets Technology with Artist Dan Holdsworth

Spread the News:ShareFor the last fifteen years, British photographer Dan Holdsworth has been blending nature, science, and technology into large-scale photographs and digital art. Much of his work focuses on glacial landscapes. Holdsworth’s major solo exhibition, “Dan Holdsworth: A Future Archaeology,” is currently premiering at the Scheublein + Bak Gallery in Zurich as part of his Continuous Topography series through September 2. Using high-end 3D imaging software ordinarily only used in scientific or military capacities, Holdsworth renders glacial landscapes in the Alps with extraordinary, unprecedented 3D precision.   Holdsworth spoke with GlacierHub about his early childhood influences, “the sublime,” and his efforts to capture Icelandic glaciers.   GlacierHub: What fieldwork did you conduct to create the images featured in this exhibit? Dan Holdsworth: For the last three years, I’ve been working with a PhD researcher named Mark Allen from Northumbria University in Newcastle [in the United Kingdom]. The first fieldwork we undertook together, three years ago now, was in the Mont Blanc massif, working on glaciers around Mont Blanc, on both the French and Italian sides. I spent initially two months there, surveying both terrestrially, with drones and by a helicopter using GPS recordings on the ground and data sampling, [and using] a huge sampling of photography surveying–usually several hundred photographs for each location.   GH: What drew you to glaciers as a subject? DH: My interest in landscape and interest in technology and human impacts on our environment. I’ve always been drawn to areas that have a tension, an edge. In my very early work, it was focused on city edges, where you see this view of humanity and nature kind of hitting each other. For me, obviously glacial landscapes have a similar aspect in terms of this edge of the human traction on glaciers. The images of glaciers are transmitted all around the globe as a symbol of climate change. In 2000, I went to Iceland for the first time, and I visited glacial landscapes in Iceland. In 2001, I started photographing a glacier called Solheimajökull, which was predominately, at that time, black, with volcanic debris melting out from the glacier. It appeared to have a very interesting tension with the industrial. This object is a byproduct of the Industrial Revolution. I went back every year for almost ten years and photographed the same location, not to document it exactly that precisely, but to more explore my relationship with it and my responses as it was changing and melting. I then subsequently made prints, which I made digital inversions of. When I made the photographs, I would always make them on a completely white-out day, and you’d see this black object in this white space.  In the final work, I made this circular realization by inverting the photograph and restoring the glacier to white. The sky becomes the black of space, so you have this immediate planetary transformation in the image.   GH: Your art blends technology with nature and science very seamlessly. What inspired this connection in your work? DH: My father was a physicist who studied in Bristol and then at the Max Planck Institute. He was a polymer physicist, and developed processes to metalize plastics. One of the companies he worked with was based in the States and he was developing coatings for space shuttles. So there were always these interesting sides of technology that I was being brought up with. Often you’d see these kinds of developments of technology, like a ghost of my dad’s work [like] some kind of metalized plastic in some food packaging, and back in the 1980s, you’d think, ‘There’s no...

Roundup: On Glaciers This Week: Raves, Yoga and Kayaks

Spread the News:ShareIcelanders Celebrate Solstice with Glacier Rave From The Daily Beast: “Sure enough, there he was: a man dressed in a head-to-toe panda costume running toward the bus and waving his hands, a sweaty tornado of furry stress, desperate not to miss the bus that would transport him to the Langjökull Glacier—and the 500-meter tunnel that will take him to the party held 25 meters beneath the icy surface. “This is the second year that the Secret Solstice festival has held the special event. Whispers of last year’s party—not to mention the insane photos—helped land not just the excursion, but Iceland’s four-day music marathon itself, on the top of the must-attend list in the world’s festival circuit.” Read more here. Indian Army practices Yoga on Siachen Glacier From Business Standard: “The second International Day of Yoga was celebrated by Army’s Fire and Fury Corps today at the Siachen Glacier, along with several other high-altitude forward locations in Leh and Kargil. “The Indian Army has incorporated Yoga Asanas into the daily routine of the soldier in High Altitude Areas deployed in harsh climatic conditions. “Practice of Yoga by soldiers in such an environment helps them to combat various diseases such as high altitude sickness, hypoxia, pulmonary oedema and the psychological stresses of isolation and fatigue.” Read more about it here.   Film-maker kayaks in Vatnajökull Glacier’s lake From Vine.co: Watch film-maker Henry Jun Wah Lee explore the Vatnajökull Glacier, and its proglacial lake by kayak.

The Humble Tour Guide, Bridge to the Natural World

The Humble Tour Guide, Bridge to the Natural World

Spread the News:ShareTour guides play an important role in visitors’ interactions with the natural world. Harald Schaller, a graduate student at the University of Iceland studying geography, argues in a chapter in the book, Tour guides in nature-based tourism: Perceptions of nature and governance of protected areas, that the tour guide is a key stakeholder in protected areas. Schaller shows in this chapter that tour guides not only translate, or help visitors find their path, but also shape visitors’ perception of nature. Furthermore, they guard fragile natural tourist sites, like glacial areas. “Tour guides are important in understanding the dynamics of the interaction of humans with nature and with each other,” Schaller wrote. Understanding the interaction between humans and nature helps decision-makers get insight into visitors’ perception of nature’s vulnerability and the way nature changes over time. For instance, tour guides working in many areas in Iceland areas have the opportunity to witness glacier retreat.   Schaller provides insight into the position of tour guides in vulnerable tourist sites. He shows how they play a role in visitors’ perception of the environment, and concludes that  tour guides should be seen as stakeholders in the decision-making process of protecting vulnerable tourist areas. His chapter begins with the author’s journey to Iceland, talking with local tour guides and exploring how other tour guides view the environment in which they are guiding the tourists. Tour guides have a long history. They are both pathfinders and mentors; they interpret information. The information they provide for people make their journey more safe and interesting. With the boom of tourism industry, the need for tour guides is also increasing. The individual concept of the environment is often linked to someone’s personal background, such as culture, experience, and beliefs. Therefore tour guides’ personal background could affect the guiding service they provide. According to World Tourism Organization (UNWTO), 2013, tourism creates one out of eleven jobs globally. The tourism industry in Iceland is expanding, so there is tremendous need for guides. However, in Iceland the quantity and stability of the labor supply is fluctuating, because many of the tour guides are migrants and seasonal workers. This poses risks for the sustainability of Iceland’s tourism industry, since the quality and consistency of guiding service suffers when there are not enough professional and experienced tour guides. As the growth of tourism continues, the expanding number of visitors threaten the future of this nature-based tourist industry. “[P]eople are more concerned with ticking Iceland off their bucket list and with sharing more of their experience online, rather than caring for the delicate environment,” Schaller writes in his article.  In an email message to GlacierHub, he mentioned his concern for what he terms “the fragility of Icelandic environments.” He added, “Due to the increased visitation (beyond expectation for many), degradation of the natural environment happens. This, in turn, threatens the future of tourism, since the image of a wild and untouched environment is affected by this increase.” Human cognition of the environment is not merely influenced by the physical existence of surroundings, such as lakes, mountains or animals, but also through their interaction with these natural surroundings. Schaller cites other sources who share this view. Lund (2013) and Ingold (2011) agreed that the environment is not a passive being. Instead, as one engages with the environment, it appears more clearly, and changes as physical interactions with it continue. So the natural environment could be seen as part of the personal experience within us as well as the objective existence of the environment.     A person’s conception of an environment is shaped by the visitors’ own memories, values and cultural background before they...
