Using the CMD mini at Fowler-Clark

We are half way through a survey of the Fowler Clark Farmstead in Mattapan.  We were set back a little by the nor’easter last week, but will be out again finishing the GPR survey on Monday and Tuesday (December 15-16).

The geophysical work in on behalf of Historic Boston Inc., who would like to keep the pastoral setting of the farmstead. Today the 200-year-old farmstead sits on half an acre at Hosmer and Norfolk streets.  It is not known when the main farmhouse was built, but it appears on maps drawn between 1786 & 1806.  The barn is from about 1860.  You can learn more about this project on their blog which as a great 3D scan done by Feldman Land Surveyors.

We have some very preliminary results from the CMD.  The CMD is one of the instruments we were able to purchase with our recent NSF grant for work in Iceland from 2015-2017.  In 2013 we got a small grant to test these out in Iceland and like the unit very much, especially the temperature compensation.   That compensation algorithm turned out to be particularly important for the current November –December survey.

We surveyed with 25 cm transect intervals and fiducials mostly at 5 m.  This is the clipped conductivity 3 (largest dipole center distance – 1.18m)  readings.  The image mostly shows the distribution of sub-surface and near surface metal.

We will post more as we process it.
