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.

Marine geologist William B.F. Ryan discusses once seemingly unlikely theories about the evolution of oceans and seas, the hunt for the wreck of the Titanic, the Biblical Flood, and more.
Scientists are using mobile instruments to measure and hopefully help reduce emissions from landfills, cities, farms, waste treatment plants and other sources where mitigation measures could be put in place.
Fires may increase stream flow for years after sweeping the surface, and temporarily increase downstream water supplies. But they may also increase the risks of landslides and floods in affected areas.
A study of an emerging zone off New Zealand suggests that the process, vital for life on Earth, may at first be localized and then develop into something much larger.
The continuation of dry conditions across a wide region has broken records going back to the year 800. Researchers believe climate change is largely to blame.
This U.N.-designated day aims to accelerate gender equity and improve access to and participation in science for women and girls.
Women scientists continue to face unequal access to resources and opportunities in climate science. This lack of gender diversity is concerning, since women around the world will bear the brunt of climate change impacts.
