Looking for the Origin of Slow Earthquakes in the Guerrero Gap
We are underway on our 48-day long expedition offshore of the west coast of Mexico near Acapulco, where the young Cocos oceanic plate dives beneath the North American plate.

Sylhet City, Geology, and Packing Up
We finished our electromagnetic survey and mini-field school in northern Sylhet, Bangladesh, with lectures and field trips to see the geology by car and boat.

Tea Gardens to the Rescue
We switched to deploying our equipment for imaging faults and the structure beneath the surface to tea gardens to get away from power lines and buried the cables to protect them from gnawing foxes.

Dealing With Rain and Rats
As we continued our geophysical measurements, we had to deal with heavy rains, flooding fields, and rats and foxes biting our cables. Many cables were broken soon after sunset, ruining the measurements.

In Sediments Below Antarctic Ice, Scientists Discover a Giant Groundwater System
For the first time, scientists have mapped in detail water locked in a deep basin far under the Antarctic ice. The discovery could have implications for how the continent reacts to, or even contributes to, climate change.

Fieldwork in Bangladesh During the End of Ramadan and Eid Festival
We have come to in Bangladesh in the pre-monsoon heat to better image the active faults beneath the surface using electromagnetic instruments. We are using the fallow fields from the just-harvested rice crop for our sites.

Defying Some Expectations, Southern Ocean Did Not Increase Carbon Uptake in Ice Ages
In much of the world ocean, there is evidence that iron-rich dust blowing from land has fertilized algae during cold period, increasing uptake of carbon from the air, and keeping things frigid. Not here, says a new study.
