Aarhus Geophysics contributes to the International Workshop EGM 2010.
participated to the International Workshop EGM 2010, which was held in Capri between in April(http://www2.ogs.trieste.it/egm/)
The workshop, whose theme was ”Adding new value to “Electromagnetic, Gravity and Magnetic Methods for Exploration”, offered a very stimulating set of presentations on the state of the art of these methods.
Aarhus geophysics contributed to the program with an oral presentation within the EM inversion session, about some important aspects in modelling AEM data for hydrocarbon exploration.
Aarhus Geophysics offers inversion of the Geoscience Australia Tempest and VTEM EM datasets
Come and meet Aarhus Geophysics in North America in May
“We just wanted to invite you to visit us at one of these two very important upcoming conferences in north America. You will get a chance to meet us in the exhibition area, to inquire about our products and services, and maybe also to attend some of our oral presentations in the area of AEM applied to groundwater management and exploration.
The first conference is the GeoCanada 2010 conference, which will be held from May 10th to 14th in Calgary, Alberta (http://www.geocanada2010.ca/). You will find Aarhus Geophysics at booth number 1022. We will be giving two talks, one in the Potential Field & Electrical Methods in Exploration session, and one in the Groundwater Exploration and Management 2: Aquifer scale methods session. Look out for them in the program.
The second one is World Environmental & Water Resources Congress 2010, held in Providence, Rhode Island, between May 16th and 20th (http://content.asce.org/conferences/ewri2010/index.html). The booth number is still to be confirmed, just look for us in the exhibit all. We will be giving a talk, together with our co-authors, in the Saltwater Intrusion Modeling and Management of Coastal Aquifers II session.”
Aarhus Geophysics announces the next Webinar, by the name:” Increased accuracy in inversion of AEM data. VTEM examples“.
The Webinar, based on a paper that at the last SAGA conference earned the special mention for technical excellence, will explain how they tackle the inversion of data from a generic helicopter TEM system. Some of the questions are the next – altitude, low pass filters, bias etc…. Some VTEM data will be used to present results, both from mining and groundwater applications.
The Webinar is scheduled for tuesday the 2nd of February 2010, at 16:00 central European time or at 09:30 central European time, and it is meant to last about 1 hour. The double slot should allow interested peo ple in all continents to participate. The Webinars are open to all interested parties. If you want to join in, please sign up by sending an email to Webinar@aarhusgeo.com.
Aarhus Geophysics ApS at Department of Earth Sciences of University of Aarhus (Denmark) which provides software and know-how for large scale surveys, presents some news about their activity.
At software level, the Aarhus Workbench has undergone a robust developing phase on the GIS components, and on the QC of inversion results: completely revolutionized the colour scale interface, created a shading option for horizontal maps, and the possibility to create comprehensive print ready pdf maps is activated. Regarding the second issue, the user can now visualize, with just few clicks, different maps on the GIS component of the parameters that allow to QC inversion results. These include, for example, data residual, difference between frame altitude input and output, model parameter sensitivity analysis, etc.
In terms of AEM data processing, inversion and survey planning it is also continuing with a number of new projects both for private and public clients worldwide. As an example, the first ever AEM survey dataset from the Venice lagoon, in Italy has processed. The results of this project are very promising in terms of applicability of AEM data to hydrogeological modeling within and underneath wetlands, lagoons, and surface waters in general. The description of the project: “Surface water–groundwater exchange in transitional coastal environments by airborne electromagnetics : The Venice Lagoon example” (pdf). The low 12.5 Hz base frequency was used on the project.
