Polygons can form either in permafrost areas or in areas that are affected by seasonal frost. The Arctic Arts Project has now photographed these Hummocks in Alaska and Greenland.
Blue ice occurs when snow falls on a glacier, is compressed, and becomes part of a glacier that winds its way toward a body of water. During its travels, air bubbles that are trapped in the ice are squeezed out, and the size of the ice crystals increases, making it clear.
As sea ice extent declined over the past years, Arctic tundra has received an increased amount of summer warmth and has gotten greener. Arctic tundra is a maritime biome, most of which can be found within 100 kilometers of seasonally ice-covered seas.
Welcome to The Arctic Arts Project a multi-year photographic study into change in the peri-arctic. The project looks to capture change in the purist of art forms and will be used to promote dialog between the science community and the art world. What does change look like? Where and how does it occur, and what will be the platform for meaningful dialog. Join us as we venture out into the arctic and bring back our interpretation of Arctic Art.
Arctic sea ice extent in February averaged 14.41 million square kilometers (5.56 million square miles). This is the third lowest February ice extent in the satellite record. It is 940,000 square kilometers (362,900 square miles) below the 1981 to 2010 long-term average of 15.35 million square kilometers (5.93 million square miles). It is also 50,000 square kilometers (19,300 square miles) above the record low for the month observed in 2005.
Faced with the decline of winter sea, ice necessary for winter hunting, and the ever present need for income. Will this culture succumb to pressures from the mining and energy worlds and abandon their historical roots as a culture? Watch for more coming in 2015.
International Award Winning Photographers Iurie Belegurschi and Kerry Koepping will co-guide an expedition up the east coast of Greenland. The photo tour is being lead through Iceland Photo Tours
For good or ill, change is a constant. Environmentally speaking, climate change appears as a rapid course of kinetic evolution. As the human existence is wrapped in questions both profound and complex regarding this change, one question that surfaces for me as an artist is: What does profound kinetic evolution look like? What is the visual response to these changes in our environment? The Arctic Arts Project looks to artistically capture the exquisite art and essence of the Arctic change; the colors, the light, the textures, the forces of change that create a sense of visceral beauty within its evolution. The Project intends to create a photographic fine art collection of works that span the northern most hemisphere of our planet. Join us as we journey through the arctic over time, exploring the visual response to Climate Change.
Most glacier caves are started by water running through or under the glacier. This water often originates on the glacier’s surface through melting, entering the ice at a moulin and exiting at the glacier’s snout at base level. Heat transfer from the water can cause sufficient melting to create an air-filled cavity, sometimes aided by solifluction. Air movement can then assist enlargement through melting in summer and sublimation in winter.
Some glacier caves are formed by geothermal heat from volcanic vents or hotsprings beneath the ice. An extreme example is the Kverkfjöll glacier cave in the Vatnajökull glacier in Iceland, measured in the 1980s at 2.8 kilometres (1.7 mi) long with a vertical range of 525 metres (1,722 ft).
Some glacier caves are relatively unstable due to melting and glacial motion, and are subject to localized or complete collapse, as well as elimination by glacial retreat.
Glacier caves may be used by glaciologists to gain access to the interior of glaciers. The study of glacier caves themselves is sometimes called "glaciospeleology".
The Vatnajokull "Crystal Cave" pictured above, as seen in February of 2015, has retreated more than 100 meters in one years time. Volcanic sediment in this cave has been documented at 1300 years old. It is anticipated that this cave will not exist in its current form after the 2015 summer melt.
