Welcome to the website of the HydroGeophysics Group (HGG). HGG is a large and highly skilled research group at the 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.

Watch the video, tTEM mit mehr Pepp, here (German text, no subtitles).
On Wednesday May 12, DRTV (the Danish national TV channel) reported from Himmark where the HGG is currenty mapping pollution with tTEM and FloaTEM. Watch it here. The item is the last one, and it starts 21 minutes and 14 seconds into the broadcast.
Through several years, the Interreg project TOPSOIL has been an important part of HGG's work and research. Much of tTEM and FloaTEM has been developed and tested in this project. Now you can read an article about the project in the RSA Region Studies Association ezine - so hop in and read more right here - besides the story there are many great photos of our equipment in action.
Over the years we have presented scientific results from Antarctica at conferences and in papers. Now you can join us and see Antarctica for yourselves. We were lucky to meet a team from PBS when we did the SkyTEM survey in 2018 and PBs have made an entire series about the research at McMurdoc. The airborne EM is in episode 2.
You can read more about the Antarctica project here.

Planen om, at man afløser de konstant kørende afværgeforanstaltninger ved Pillemark Losseplads på Samsø med monitering og mulighed for at skride ind, hvis det bliver nødvendigt, vækker bekymring for grundvandskvaliteten på Samsø. Der planlægges et borgermøde, hvor samsingerne skal diskutere og tage stilling til projektets planer.

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 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, 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, Phys.org, Silicon Republic, and Knoxville News Sentinel.
