River bed mapping with marine seismic

From smoke to rain and mud: Having recently returned from a geophysical survey close to the wildfires in Alberta, our geophysics crews were straight back out on the next job. For the last weeks they’ve been out on the Athabasca River collecting marine sub bottom profiling data to map sediments and bedrock to help in an engineering river crossing project.

 It gets pretty cramped once you fit all of the equipment, 3 scientists and an operator into one boat.

In this case crews deployed a seismic source that weighed over 250 pounds. The seismic source was kept buoyant as it was pulled behind the boat by 3 small pontoons.

Bodies of water can present a particularly challenging environment to acquire data for site characterization. As well as seismic methods, we provide a range of water-borne geophysical surveys that help to provide information where other forms of data acquisition are limited. 

The crews will be out again later this month collecting resistivity data on the river.
