How we compare more than 100 GPR data sets
Throughout the past one and a half years, we collected more than 100 individual GPR data sets for VEMOP by surveying roughly once a month with two different systems at four test sites. A huge amount of data and a challenge, when it comes to the actual data analysis.

Why we use two GPR systems for monitoring
It has been a while since we last posted an update on VEMOP. So, what happened these last six months?

Why skiing conditions are relevant for GPR surveys
How to prevent a 1.5t motorised georadar from acting as a very expensive snow plough AND getting usable GPR data. More about our winter surveys.

Teaching our georadar how to ski
Winters in Norway can be cold and snowy. In order to be able to continue our monitoring surveys, we had to teach our georadar how to ski. After all, it's from Sweden ...

How to monitor a frost line
One of the environmental factors we are interested in is the depth to which the ground freezes during the cold season. In order to measure this so-called frost line, we had to get creative. Also, Erich dyed his bathroom blue.

Setting up the first monitoring station
How we set up our first monitoring station at Hovland and why duct tape was of the essence!

Selection of test sites
Choosing four test sites representative of archaeological structures as well as environmental factors present in Vestfold proved more difficult than anticipated

First reference group meeting
At the beginning of March 2020, VEMOP held its first reference group meeting in Oslo. Project members met with representatives of stakeholder institutions and discussed the project's approach and what its results could mean for Norwegian archaeology.
