Antarctic-wide array of high-resolution ice core records reveals pervasive lead pollution began in 1889 and persists today
McConnell, Joseph R.; Maselli, Olivia J.; Sigl, Michael; Vallelonga, Paul; Neumann, Thomas; Anschütz, Helgard; Bales, Roger C.; Curran, Mark A.J.; Das, Sarah B.; Edwards, Ross; Kipfstuhl, Sepp; Layman, Lawrence; Thomas, Elizabeth R. (Journal article, 2014)Interior Antarctica is among the most remote places on Earth and was thought to be beyond the reach of human impacts when Amundsen and Scott raced to the South Pole in 1911. Here we show detailed measurements from an ... -
Combining airborne electromagnetic and geotechnical data for automated depth to bedrock tracking
Christensen, Craig; Pfaffhuber, Andreas Aspmo; Anschütz, Helgard; Smaavik, Tone Fallan (Journal article, 2015)Airborne electromagnetic (AEM) survey data was used to supplement geotechnical investigations for a highway construction project in Norway. Heterogeneous geology throughout the survey and consequent variable bedrock threshold ... -
Feltarbeid snøradar
Anschütz, Helgard (NGI-rapport;20180070-01-TN, Research report, 2018-11-13)GBV-prosjektet 20180070 "snøegenskaper fra dronebaserte radarmålinger" er et delmål å innhente feltdata med GPR, både fra bakken og i luft. Radardata skal gi informasjon om snødybde, lagdeling i snø og snøegenskaper. Det ... -
Peatland Volume Mapping over Resistive Substrates with Airborne Electromagnetic Technology
Silvestri, Sonia; Christensen, Craig; Lysdahl, Asgeir Olaf Kydland; Anschütz, Helgard; Pfaffhuber, Andreas Aspmo; Viezzoli, Andrea (Peer reviewed; Journal article, 2019)Despite the importance of peatlands as carbon reservoirs, a reliable methodology for the detection of peat volumes at regional scale is still missing. In this study we explore for the first time the use of Airborne ... -
Resistivity and chargeability survey for tunnel investigation: a case study on toxic black shale in Norway
Bazin, Sara; Lysdahl, Asgeir Olaf Kydland; Viezzoli, Andrea; Gunther, T; Anschütz, Helgard; Scheibz, Jürgen; Pfaffhuber, Andreas Aspmo; Radic, T; Fjermestad, Halldis (Journal article; Peer reviewed, 2017)In the past few years, the focus on Alum shale hazards and the need for efficient mapping tools have increased in Norway. Alum shale is highly toxic and poses a substantial obstacle to infrastructure development such as ... -
