Who are we?

Welcome to the website of the HydroGeophysics Group (HGG). HGG is a strong and quite large research group at Department of Geoscience, Aarhus University, Denmark, working primarily with hydrogeophysics. The research covers many aspects of hydrogeophysics, instrument development, data collection, processing and inversion algorithms, software development, as well as integration of the geophysics results into geological and hydrological models.

NEW NSF VIDEO: Discovery made beneath Antarctica's McMurdo Dry Valleys
Using a novel, helicopter-borne sensor to penetrate the surface of large swathes of terrain, a team of researchers supported by the National Science Foundation (NSF) has gathered compelling evidence that beneath Antarctica's ice-free McMurdo Dry Valleys lies a salty aquifer that may support previously unknown microbial ecosystems and retain evidence of ancient climate change.

The article has generated widespread media attention - see below:

Danish Technology detects new knowledge about the Antarctic underground.
Danish Radio has interviewed Professor Esben Auken from the Hydrogeophysics Group about the results of the Antarctica project. Read the inverview here (in Danish) and watch the video!

Jill Mikucki’s Antarctica study in the news

Jill Mikucki, a microbiology assistant professor, was part of a team that detected extensive salty groundwater networks in Antarctica using a novel airborne electromagnetic mapping sensor system called SkyTEM. The hidden interconnected lakes could sustain life and shed light on ancient climate change. They also may provide the basis for future exploration of a subsurface habitat on Mars.

The Washington Post featured Mikucki and the study in this article.

Numerous national and international media outlets also featured the research, including the ABC Science, Christian Science Monitor, Huffington Post, Discovery, Daily Mail, the Verge, New Scientist, Business Insider Australia, Business Standard, Yahoo! News, International Business Times, Irish Examiner, Science Mag,, Silicon Republic, and Knoxville News Sentinel.

Discovered deep under Antarctic surface: Extensive, salty aquifer and potentially vast microbial habitat

Helicopter-borne instrument shows what lies beneath Antarctica's ice-free Dry Valleys. Using a novel, helicopter-borne sensor to penetrate the surface of large swathes of terrain, a team of researchers supported by the National Science Foundation (NSF) has gathered compelling evidence that beneath Antarctica's ice-free McMurdo Dry Valleys lies a salty aquifer that may support previously unknown microbial ecosystems and retain evidence of ancient climate change.

In early December 4 scientists from the airborne division of the China Geological Survey visited Aarhus University, GEUS and SkyTEM Surveys to discuss groundwater resource mapping in China using Danish technology. 

After the NICA end conference, results from the project have been covered by Danish media - an article in Berlingske: Danes develop helicopter technique that saves millions. Read the article here (Danish).

WATCH THIS! A great 7 min long video on SkyTEM aquifer mapping in Nebraska. Apart from great scenery, nice graphics explain how the technology works and the purpose of the mapping.

If you are looking for well known faces, Toke Højbjerg Søltoft from HGG is working with the system about 4 minutes into the video. Jim Cannia, the American scientist explaining the perspectives of the technology, has been in Aarhus many times and is a very good friend of HGG.

HGG in TV2 Østjylland
On 11 March HGG again had interesting visitors. The well known reporter Søs Kjeldsen and photographer Jeppe Jermiin from TV2 Østjylland. TV2 Østjylland visited the group with the purpose of making a new installment in the ongoing series 'IQ - close to the clever heads'. This time about groundwater resource mapping.

The show can be seen on TV2 Østjylland on 22.4 at 22.30, 23.4 at 12.30 and again 30.4 at 17.30 and on TV2 Østjylland's website:
