The new permanent exhibition at The Arctic University Museum of Norway tells the story of our planet from a geological perspective, including pioneering research conducted at CAGE<\/h2>\n

From a scientific standpoint, the most reliable way to predict the future is by examining the past. Geological remnants help us to paint a picture of evolutionary processes that we are only beginning to understand, and many of these are on display as part of a new, permanent exhibition aimed at school-aged children at the Troms\u00f8 Museum called \u2018TellUs \u2013 from stardust to modern technology.\u2019<\/em> Evolution, in terms of ice sheet migration and its potential effect on climate change, is also a big theme at the Center for Arctic Gas Hydrate, Environment and Climate (CAGE) at UiT The Arctic University of Norway. The center is featured in the TellUs<\/em> exhibition as part of the \u2018modern technology\u2019 portion of the story.<\/p>\n

A journey through time<\/h2>\n

The TellUs<\/em> exhibition leads the viewer on a journey that begins with the Earth as a ball of fire some 4,540 million years ago. This unimaginable expanse of time is brought into perspective by a 2.3-meter stack of A4 paper, using various colors to represent different periods of development in the Earth\u2019s lifespan.<\/p>\n

This stack is made up of 22,700 sheets of paper, depicting the lifespan of the Earth. Shockingly, only the final sheet of paper represents modern human existence.<\/figcaption><\/figure>\n

Other abstract concepts in geological history are made relatable by presenting them in a local context, while encouraging physical interaction with various touchscreens, rocks, fossils, minerals, and models. This is done especially well through several exhibits covering geological processes amongst the four most prominent mountain peaks of the Troms\u00f8 area: Store Bl\u00e5mannen, Soltindan, Tromsdalstind, and Bentsjordtind.<\/p>\n

CAGE research highlighted<\/h2>\n

Research performed at CAGE regarding Arctic gas hydrates becomes a major focus in the exhibit as we enter present day in the timeline. A gas hydrate is essentially methane ice, a solid form of a potent greenhouse gas. These crystalline structures are found in and under the seabed in the Arctic. They are stable in cold conditions and under high pressure, such as under the frigid Arctic ocean. Ice sheets in areas such as Greenland and west Antarctica help to keep the gas hydrates stable. But as these ice sheets begin to melt and recede at a much quicker rate, there is a growing concern that large quantities of methane gas could be destabilized and released abruptly.<\/p>\n

Quantities of methane gas in the atmosphere have greatly escalated on a global scale in the recent past, with 70% of the increase credited to industrial and agricultural expansion. However, natural sources of methane \u2013 which is a greenhouse gas with 30x the power of CO2 – are still to be better understood.<\/p>\n

Fortunately, scientists have discovered that an abrupt release of methane happened about 12000 years ago, as evidenced by giant craters found in the ocean floor offshore Svalbard and on land in the Siberian permafrost. By studying the evolution of ice sheet dynamics of the past as well as current conditions at gas hydrate and crater sites, scientists hope to understand how rapid climate change will effect these huge stores of methane.<\/p>\n

A digital experience<\/h2>\n

There are several items to investigate at the CAGE part of the exhibition, most of them delivered visually. These include two explainer videos summarizing the risks and scale of the methane problem, a video featuring remotely operated vehicle (ROV) footage from a research expedition to the Barents Sea, and 10 additional videos of CAGE scientists explaining various elements of this important research. Also in place is an unusually well-preserved methane chimney carefully delivered to the museum from Italy.<\/p>\n
