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.

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.
A new book, the second in a series of primers with the Earth Institute imprint, provides an interdisciplinary overview drought, bringing together many fields including climate science, hydrology and ecology.
Recent research indicates that salt is accumulating in the environment and poses an emerging threat both to ecosystems and human health.
As the world population continues to grow, global demand for food could increase dramatically by 2050. Yet the impacts of climate change threaten to decrease the quantity and quality of our food supplies.
Many countries are making progress on improving water sanitation and protecting marine ecosystems. But air pollution continues as a leading health problem in many nations, and fisheries are deteriorating almost everywhere.
Human-influenced climate warming has already reduced rainfall and increased evaporation in the Mideast, worsening water shortages. Up to now, climate scientists had projected that rainfall could decline another 20 percent by 2100. But the Dead Sea cores suggest that things could become much worse, much faster.
For Mexico City’s biggest businesses and its poorest neighborhoods, rainwater harvesting could help address an enormous water crisis plaguing the city, a recent Columbia Water Center study found.
On every continent and ocean, Earth Institute field researchers are studying the dynamics of climate, geology, natural hazards, ecology and other subjects with direct applications to the challenges facing humanity.
