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.

Struggling With Towed Equipment, Repairing GPS, and Home
We switched to a towed electromagnetic system to image the fresh and saline groundwater in Bangladesh, and ran into a variety of problems, including high winds, strong currents and running aground.

Continuing the Survey: Watermelon and Winds
Continuing our electromagnetic survey of fresh and saline groundwater, we saw the landscape change from lush watermelon fields to fallow rice fields as the salinity increased towards the sea.

Barisal and the Eastern Channel
We are continuing our measurements of fresh and saline groundwater in Bangladesh using electromagnetic instruments. We finished our first set of measurements and have now shifted farther east near Barisal where groundwater is fresher.

Deploying in the Mangrove Forest
We continued our electromagnetic expedition to image fresh and saline groundwater into the Sundarbans Mangrove Forest, the world’s largest. While guards protected us from tigers, it was a wild boar that dug up some of our equipment.

Scientists Map Huge Undersea Fresh-Water Aquifer Off U.S. Northeast
In a new survey of the sub-seafloor off the U.S. Northeast coast, scientists have made a surprising discovery: a gigantic aquifer of relatively fresh water trapped in porous sediments lying below the salty ocean.
