Hi all

Aarhus Geophysics Aps 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.

Hi all,

Aarhus Geophysics would like to announce that is it available for processing and inversion of the Tempest and VTEM electromagnetic datasets from the Paterson Province and Pine Creek survey, in Australia. These EM datasets are available from Geoscience Australia, as a mean to promote the exploration in this region.

As you probably know already, we are experts in the field of processing and inversion of AEM data from different systems. Our methodologies and expertises are particularly suitable for Uranium exploration, and have already been applied to this target.

We therefore offer to the companies with tenements or different interests in the region a robust inversion of the EM data (both smooth and with few layeres) that could be very valuable for the geological interpretation and the pre-exploration phase.

Hi all, 

this is not the usual newsletter informing about software update or Webinars. 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. 

So, it is all for now, I will leave for other newsletters coming up shortly the exiting news about software release, and consulting projects we are currently involved in.

Looking forward to seeing you in North America soon. 

Best Regards

Hi all, first of all happy new year to everyone.

It has been a while since our last Webinar. It is time to get back on track, and to announce what we hope will be a popular 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 we tackle the inversion of data from a generic helicopter TEM system. We will touch topics such as altitude, low pass filters, bias etc.... We will then use some VTEM data to present results, both from mining and groundwater applications.

The Webinar is scheduled for tuesday the 2^nd 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 people 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 This e-mail address is being protected from spambots, you need JavaScript enabled to view it . Please specify the time slot that suites you.

I would like to take the opportunity to give visibility to a paper published few days ago on Geophysical Research Letters (Viezzoli et al.) by the title: Surface water-groundwater exchange in transitional coastal environments by airborne electromagnetics: The Venice lagoon example. Do not hesitate to contact us if you are interested in the article.

Hi all,

It has been a while since last newsletter of Aarhus Geophysics. They have been however very busy times, and here we present some of the most relevant news.

At software level, the Aarhus Workbench has undergone a robust developing phase on the GIS components, and on the QC of inversion results. On the first issue, we have completely revolutionized the colour scale interface, created a shading option for horizontal maps, and activated the possibility to create comprehensive print ready pdf maps. 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.

Our consultancy in terms of AEM data processing, inversion and survey planning is also continuing with a number of new projects both for private and public clients worldwide. As an example, we processed the first ever AEM survey dataset from the Venice lagoon, in Italy. 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. We will keep you posted when the paper we are working on will be accepted. For the moment, have a look at the expanded abstract.

Best Regards

I take the opportunity to let you know that, also thanks to a cooperation between Aarhus university and Geoscience Australia, the Aarhus Workbench has been chosen by Geoscience Australia as the software for processing and inversion of a large SkyTEM survey. The survey is part of GA's "Broken Hill MAR Project"project.

Hi all, 

this is not the usual newsletter informing about software update or Webinars. We just wanted to invite you to visit us at one of these two upcoming conferences. The first one is the Near Surface 2009 conference, which will be held from Sept. 7 to 9 in Dublin (http://www.eage.org/events/index.php?eventid=110). You will find Aarhus Geophysics at booth number 16. The second one is SAGA 2009, held in Swaziland between between 13 and 18 of September (http://www.sagaonline.co.za/2009Conference/index.htm). There look for booth number 4. Come and ask us about our products and services, and let us show you how we can get more out of your AEM data. 

Best Regards

Hi,

Aarhus Geophysics would like to give you an update regarding the latest developments in our software, and in our consulting activities.

The Aarhus Workbench now has a general importer for models resulting from inversion of AEM data performed outside of the Workbench. This allows to import models, together with data and forward responses, generated with inversion software (be it based on approximate or exact forward responses) other than our own. It is then possible to use the powerful visualization tools embedded in the workbench to inspect and present these results. In practice this allows also the user to display and compare within the GIS environment of the Workbench the results obtained from different inversion packages or techniques (e.g., EMflow, from Encom http://www.encom.com.au/).   

On the consulting side, we are happy to announce that we can process and invert with the Laterally Constrained  Inversion both AeroTEM data (from Aeroquest http://www.aeroquestsurveys.com/english/index.php) and VTEM data (from Geotech http://www.geotech.ca/) for you, before these systems are fully supported in the Aarhus Workbench.

Remember also our upcoming Webinar on "inversion of HEM data with the Aarhus Workbench", scheduled for April 22^nd, at 14:00 (Central European time). If you are interested, and haven't done it yet,  please sign up by sending an email to This e-mail address is being protected from spambots, you need JavaScript enabled to view it .
 

Thanks for you time, 

Best Regards

Hi

First of all let me take this occasion to thank the 23 delegates that attended our workshop on Processing and Inversion of AEM data given in Adelaide just after the ASEG conference last month. It was a great privilege, and also a challenge, to have such a diverse audience, spanning from consultants working in the mining sector to governmental agencies dealing with groundwater issues, to providers of airborne surveys. We will probably do it again in Sydney.

However, the real reason for the newsletter is that we are happy to announce another Aarhus Geophysics Webinar to be given soon, by the title "Inversion of HEM data in the Aarhus Workbench".

The Webinar will focus mainly on importing of HEM data (e.g., RESOLVE data) into the Workbench, inverting them, and assessing the results. If there is time, it will also touch briefly the topic of creating maps and presenting results in the GIS environment. However, the latter will be the topic of a dedicated future Webinar.    

The HEM inversion Webinar is the third of a series of Webinars, covering different modules of our software that we started at the beginning of the year, and will continue in the future.

The Webinar is scheduled for wednesday the 22^nd of April 2009, at 14:00 central European time, and it is meant to last about two hours. Hopefully this time will suite most people in all continents. Let us know if you can't make it at that time, and we may set up another Webinar dedicated to people living in some remote place ! 

The Webinars are open to all interested parties. If you are interested, please sign up by sending an email to This e-mail address is being protected from spambots, you need JavaScript enabled to view it .
 

Remember also to check out our website www.aarhusgeo.com for a complete overview of our products and services. We will however send another newsletter shortly with information on the latest developments in Aarhus Geophysics, both on software and services sides. Just a teaser here ... different HTEM systems...

Hi and happy new year to everybody.

We are happy to announce that, in the very near future, Aarhus Geophysics will host both a workshop on inversion of AEM data at the ASEG 09 conference, and a series of Webinars on selected modules of our software products.

The workshop on inversion of AEM data will take place on Februrary the 26^th, in correspondence to the end of the ASEG 09 conference, held in Adelaide, in Australia. It will cover aspects of processing and inversion of AEM data from different airborne systems, both time and frequency domain, and it will be conducted using the Aarhus Workbench software. More info on the workshop are available from http://www.sapro.com.au/ASEG/workshops.htm (workshop number 9). If you are interested, registration for the workshop is open on the ASEG website: http://www.sapro.com.au/ASEG/registration.htm. We will also be present at ASEG 09 as exhibitors, at stand 99.

This is the schedule of the first series of Webinars, which will focus on Sitem/Semdi, our software for processing and inversion of TEM data.

• Thursday the 22^nd of January at 21:00 (Central European time): processing and inversion of Protem 47/57 data.

• Monday 26^th of January at 21:00 (Central European time): processing and inversion of Terratem data.

The Webinars are open to all interested parties, but require some basic knowledge of TEM data processing and inversion. If you are interested in any of the Webinars, please sign up by sending an email to This e-mail address is being protected from spambots, you need JavaScript enabled to view it .

Other Webinars on other software modules (i.e., processing and inversion of SkyTEM data, of HEM data, of DC data, etc...) will be scheduled soon. Feel free also to write to This e-mail address is being protected from spambots, you need JavaScript enabled to view it to request a Webinar on a selected topic.

Until recently, we were known as Skyware. We are happy to announce that as of September 1 2008 we are called

Aarhus Geophysics

The name was chosen to stress our close connection to University of Aarhus, its reputation and the research that is being carried out there. The name also reflects our key expertise: Geophysics. The name of our main product remains unchanged - the Aarhus Workbench.

Our aim is for Aarhus Geophysics to be associated with high quality software products and services in the field of geophysics.

New logo...

In connection with the name change, we launch a new logo. You can see it at the top of each page here on our website. We like it - and we hope you do, too.

...and new website

Now that we change the name and the logo, the time is right for kicking off a new website. We have tried to make it better and more intuitive than the old one, but please let us know if you miss anything on the webpages.
