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.

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 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.

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.

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.

I am back in Bangladesh to explore the distribution of fresh and saline groundwater in the coastal zone, needed for drinking in the dry season.

Earth Institute researchers are in the field studying the dynamics of the planet on every continent and every ocean. Here is a list of projects.

Gases collected from ancient groundwater provide a compelling portrait of how much past temperatures have swung back and forth.

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.
