Syntactic flotation: the Scripps way

Today I interviewed the OBS group from the Institute of Geophysics and Planetary Physics (IGPP) at the Scripps Institution of Oceanography, which is part of the University of California San Diego. Scripps has a long history of making OBSs. In the early 1990’s, I was a postdoctoral fellow at IGPP and at that time thereContinue reading “Syntactic flotation: the Scripps way”

Zen and the art of magnetotelluric measurements

PiLAB is a unique experiment in many ways, one of which is that ocean bottom seismometers and magnetotelluric instruments are co-located. This allows the comparison of two very different physical properties of the plate and underlying mantle – elasticity and the conductivity – which together offer insights into the nature of tectonic plates, how theyContinue reading “Zen and the art of magnetotelluric measurements”

Magnetic attractions at the equator

The weather remains good, the sea is calm and we are about to cross the equator for the third time. We are steaming westward away from Africa and have some long transits between stations. Time to enjoy the sunsets and sunrises. But, this has also given us some time to start acquiring magnetic data. ElectromagneticContinue reading “Magnetic attractions at the equator”
