Such insights are particularly important for the Arctic, where warming is happening at a rate four times faster than the global average and where important climate tipping points are of global societal concern. Paleo Ecologist at GEUS, Heike Zimmermann, searches to answer how far back in time we can use DNA to uncover interactions between climate, the ocean, and the biosphere. And how arctic marine ecosystems have reacted to past climate changes. 2026-03-18T12:25:55+00:00 yes 526 Geological Survey of Denmark and Greenland https://www.undergroundchannel.dk/the-color-of-ice-trailer-2 https://www.undergroundchannel.dk/v.ihtml/player.html?photo_id=121938928 https://www.undergroundchannel.dk/64968559/121938928/6757396979162fa9e3253a5e78e8ed9f/video_medium/the-color-of-ice-trailer-2-video.mp4 https://www.undergroundchannel.dk/64968559/121938928/6757396979162fa9e3253a5e78e8ed9f/small/the-color-of-ice-trailer-2-thumbnail.jpg The Color of Ice Trailer The landscape of North Greenland is changing, fast.

En del af Draved Skov blev dengang brændt af som led i et arkæologisk og geologisk forsøg, der blandt andet skulle afdække ildens påvirkning på en skov. Forskere fra Nationalmuseet og DGU, nu De Nationale Geologiske Undersøgelser for Danmark og Grønland (GEUS), fældede et stykke skov med flinteøkser og brændte det af for at dyrke afgrøder i asken.

In response to concerns from the Government of Greenland over the potential remobilization of its contaminants by climate change, the Government of Denmark established the Camp Century Climate Monitoring Programme in 2017. Since the programme was established, scientists have been able to retrieve precise weather data from Camp century. Their new study suggest that snow will continue to accumulate at Camp century within the present century, which means that the abandoned camp will remain buried under ice.

New research the past 5 years has shown an increase in activity at the volcano through surface inflations and gas explosions. In this project, we aim to determine the pressure and temperature conditions in the magma chamber, and identify the source and evolution of Domuyo, using isotope analyses, age dating and crystal compositions. This knowledge is essential to understand the volcano and potential future eruptions. Vulkanen Domuyo er den højeste vulkan i Argentina, og karakteriseret ved dens ekstremt silikarige og sejtflydende magmasammensætninger.

ET quantifies the transport of water from land to the atmosphere. In the ALL-WET project, we apply novel satellite remote sensing methods to study ET over the Sengal basin in West Africa. In particular, we utilize microwave based data which are tolerant to clouds. Thereby, microwave satellites provide all weather estimations of ET which is highly relevant in sub tropical and tropical regions of the world, like the Senegal basin, which are generally strongly affected by cloud cover. 2019-11-18T12:15:13+00:00 yes 244 Geological Survey of Denmark and Greenland Allwet Geus Julian water https://www.undergroundchannel.dk/sustainable-tourism-and-natural https://www.undergroundchannel.dk/v.ihtml/player.html?photo_id=57480655 https://www.undergroundchannel.dk/49543316/57480655/005e92e0cb3bb480cf560c18635d13a8/video_medium/sustainable-tourism-and-natural-video.mp4 https://www.undergroundchannel.dk/49543316/57480655/005e92e0cb3bb480cf560c18635d13a8/small/sustainable-tourism-and-natural-thumbnail.jpg Sustainable tourism and natural resources The research project examines the dynamic linkages between tourism and natural resources in South Greenland, and explores pathways towards sustainable tourism development in and around Kujataa, a new UNESCO World Heritage Area in the region.

In response to concerns from the Government of Greenland over the potential remobilization of its contaminants by climate change, the Government of Denmark established the Camp Century Climate Monitoring Programme in 2017. Climate and ice monitoring instruments were established at Camp Century in summer 2017. The sub-surface debris field was also surveyed by ice-penetrating radar. This monitoring programme aims to refine knowledge of the spatial extent and vertical range of the debris field, as well as project changes in meltwater production and near-surface ice-sheet structure in response to climate change, in order to inform science-based discussions of the shifting fate of Camp Century. This monitoring programme is jointly funded by GEUS and the Danish Cooperation for Environment in the Arctic (DANCEA) within the Danish Ministry for Energy, Utilities and Climate.

As our climate changes from enhanced greenhouse effect (i.e. global warming), the air now holds more moisture. Consequently, rainfall and snowfall intensity is increasing. So, the question is what is the balance between increasing snow fall and increasing ice melt? Professor Jason Box has been working to answer this question using a ski-based traverse on the Greenland Ice sheet in 2017. With some low tech measurements of how much does the snow weigh, he can check the high tech - satellites and climate models. The results revealed that although snowfall is important for building up glaciers, melting is still dominating and so the balance is negative For more information please visit www.geus.dk or <a href="https://www.jasonbox.net"><a href="https://www.jasonbox.net"><a href="https://www.jasonbox.net"><a href="https://www.jasonbox.net"><a href="https://www.jasonbox.net"><a href="https://www.jasonbox.net"><a href="https://www.jasonbox.net"><a href="https://www.jasonbox.net">https://www.jasonbox.net</a></a></a></a></a></a></a></a> 2018-02-22T08:27:37+00:00 yes 266 Geological Survey of Denmark and Greenland geus greenland jason traverse https://www.undergroundchannel.dk/stories-from-the-geus-archive-searching-for-oil https://www.undergroundchannel.dk/v.ihtml/player.html?photo_id=21451874 https://www.undergroundchannel.dk/19476789/21451874/199e8223c3d3a6037e6237650360244b/video_medium/stories-from-the-geus-archive-searching-for-oil-video.mp4 https://www.undergroundchannel.dk/19476789/21451874/199e8223c3d3a6037e6237650360244b/small/stories-from-the-geus-archive-searching-for-oil-thumbnail.jpg STORIES FROM THE GEUS ARCHIVE - SEARCHING FOR OIL IN NORTH GREENLAND IN 1985 During the 1980ies geologists were looking for energy all over the world, and in 1984 the first systematic oil geological investigations were started in North Greenland to map the hydrocarbon potential.

Niclas Scott Bentsen - associate professor at Department of Geosciences and Natural Resource Management - is currently investigating how to mitigate climate change by replacing fossil resources with bio mass. On a large scale projects like this would mean a serious cut to carbon emissions.

Partly inspired by the Canadian region Nunavut where a significant group of carvers use soapstone figurines sold as “inuit art” to supplement their income, a new cross-disciplinary research-project from GEUS, the University of Greenland and the Natural History Museum of Denmark aims to build a similar line of products in the Nuuk area. Making knowledge on soapstone occurrences available is a first step in this direction.

"Practical men may despise the tales, earnest men condemn them as lies, some even consider them wicked ; one refused to write any more for a whole estate ; my best friend says they are all ' blethers.' But one man's rubbish may be another's treasure, and what is the standard of value in such a pursuit as this?"

In our ever changing cities we have stacked all different kinds of resources into buildings. In this lecture Rechberger shows how he and his colleagues have ‘mapped’ the building stock of the city of Wienna seeing buildings from a resource perspective. The lecture was given at a MiMa Meeting April 2016.

For the last decennials this topic has gained focus around the world with a growing population and an ever broader use of minerals in modern products and technologies. An insight to the US perspective of that is here given by Steven Fortier, Director of National Minerals Information Center, U.S. Geological Survey. The presentation is based upon the report Assessment of critical minerals: Screening methodology and initial application, released march 2016. In this report a screening of 50 elements is featured as a base of discussion for a national call to action. The lecture was given at a MiMa Meeting on Geocenter Denmark, February 4th, 2016.

In this lecture Professor John Ludden, Executive Director of the BGS, explains the thoughts behind the project, and how the research will provide new scientific insight in monitoring the environment impact of shale gas development. BGS estimates shale basins in the country may hold more than 1.3 quadrillion cubic feet of natural gas. However, hydraulic fracturing or fracking is a technique that has been largely debated controversial. A consortium led by BGS and university partners will carry out groundwater, regional air quality and seismic activity research at two proposed fracking sites in Lancashire. 2015-04-30T11:06:01+00:00 yes 1413 Geo Lectures fracking geo lectures ressources https://www.undergroundchannel.dk/water4coasts-1 https://www.undergroundchannel.dk/v.ihtml/player.html?photo_id=11496468 https://www.undergroundchannel.dk/10820440/11496468/fde7fdb02114761c4c0ab08dd3a0bb74/video_medium/water4coasts-1-video.mp4 https://www.undergroundchannel.dk/10820440/11496468/fde7fdb02114761c4c0ab08dd3a0bb74/small/water4coasts-1-thumbnail.jpg Water4Coasts #1 Researchers are currently investigating how the injection of treated fresh surface water into the groundwater reservoir can protect valuable water resoures in coastal zones and prevent salt water intrusion into groundwater used for drinking water.

The general believe is that the hills was formed by the last ice age, which left large deposits and shaped the landscape. However a group of scienteist from Aarhus University are now investigating another theory. A theory which would date the landscape back to an even older origin. The answer could come from a seismic investigation of the underground. We followed a group of students in the field and learned how they approached this theory. 2015-04-13T16:55:21+00:00 yes 303 Dept. of Geoscience Aarhus University field work https://www.undergroundchannel.dk/fluctuations-in-glaciers-throughout-the-last-12000 https://www.undergroundchannel.dk/v.ihtml/player.html?photo_id=11472077 https://www.undergroundchannel.dk/9826383/11472077/88f8ca4ac17e2ae637649ef83bd9f871/video_medium/fluctuations-in-glaciers-throughout-the-last-12000-video.mp4 https://www.undergroundchannel.dk/9826383/11472077/88f8ca4ac17e2ae637649ef83bd9f871/small/fluctuations-in-glaciers-throughout-the-last-12000-thumbnail.jpg Fluctuations in glaciers throughout the last 12.000 years Astrid Strunk has just begun her PhD about fluctuations in glaciers on Greenland during the last 12.000 years in search of a model to determine future climate change. 2015-04-10T03:17:44+00:00 yes 341 Dept. of Geoscience Aarhus University climate geotalk glaciers greenland melting ice science https://www.undergroundchannel.dk/climate-impact-on-biodiversity-change-in https://www.undergroundchannel.dk/v.ihtml/player.html?photo_id=11471070 https://www.undergroundchannel.dk/10820438/11471070/bbf520f9733fb24be65a6d06e1a1e9b0/video_medium/climate-impact-on-biodiversity-change-in-video.mp4 https://www.undergroundchannel.dk/10820438/11471070/bbf520f9733fb24be65a6d06e1a1e9b0/small/climate-impact-on-biodiversity-change-in-thumbnail.jpg Climate impact on biodiversity change in deep time #1 A group of scientists has initiated a project to study whether astronomical cycles has an impact on biodiversity change in deep time.

"His poems write themselves into the dark ecology; an ecological disaster-consciousness devoid of any sentimental relationship with nature. Not all poets use language spanning from "Cretaceous" to "the future", and from the "Mariana Trench" to the "Milky Way". "Theis Ørntoft creates a universe where layers of natural history, self history, world history, architectural history , biblical history , and history of science overlay each other in a strange poetic geology" - Politiken. We have spoken with Theis on the anthropocene matter and how it affects his poetry. 2015-02-06T11:11:01+00:00 yes 245 Anthropocene anthropocene artist poetry https://www.undergroundchannel.dk/the-anthropocene-ferdinand-ahm-krag https://www.undergroundchannel.dk/v.ihtml/player.html?photo_id=10876567 https://www.undergroundchannel.dk/10820439/10876567/e68852ee09e35d58ce9d51dd53b733a4/video_medium/the-anthropocene-ferdinand-ahm-krag-video.mp4 https://www.undergroundchannel.dk/10820439/10876567/e68852ee09e35d58ce9d51dd53b733a4/small/the-anthropocene-ferdinand-ahm-krag-thumbnail.jpg The Anthropocene - Ferdinand Ahm Krag A growing number of scientists believe that we have entered a new geological epoch – the Anthropocene.

In a story about arctic science, traditional folklore and climate change, we meet them in their daily interaction with nature. An old greenlandic legend tells the story of the Mother of the Sea. If humans treat her bad, she holds back the sea creatures so that people will starve. The story is a testimony of respect to nature and is perhaps more relevant now than ever before.
