John and Brian using the DUALEM-21 at Stóra-Seyla
Today we finished our first survey with the DUALEM-21. This is just half of the 4-meter-long DUALEM-421 – the instrument that John brought on the bus from Reykjavik. Tomorrow we’ll be surveying the grid at Seyla again in the opposite direction, and then we’ll take a look at the data. We will probably be using the full 4-meter DUALEM-421 later in the season.
We’ve already finished surveying in both directions with the CMD, a smaller multi-sensor EM instrument (see the photo in the last post). These multi-sensor EMs allow us to penetrate multiple different depths at the same time. A single survey with the CMD gives us six complete data sets to analyze. Preliminarily, what we’ve seen from the CMD data looks very good!
Today we are also welcoming the rest of our crew, who are joining us from Kenyon College – Dr. Kimmarie Murphy and two students, Hannah and Myra, who will be helping with the cemetery excavation and skeletal analysis as well as geophysical survey. It’s great to have them here with us!
As for me, I’m thrilled to be back in Iceland again. This is one of my favorite places in the world, and I have a really good feeling about this summer!
