A Key U.S. Earth-Sciences Official Visits Columbia to Explore Research Ideas
Oceanographer Richard Spinrad of NOAA participated in a town hall and discussed funding opportunities with Columbia Climate School researchers.
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.
Sailing Around the Bangladesh Coastal Zone
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.
Water Content Controls the Depth of Magma Storage Under Many Volcanoes, Says Study
Research into volcanoes in the Aleutian Islands and elsewhere overturns the conventional understanding of what controls the depth at which rising magma is stored.
How These Women Are Contributing to a Sustainable Tomorrow
For last month's International Women’s Day, we highlight a few women in the Columbia Climate School who are leading on climate science and adaptation, and helping to promote equity, sustainability, and resilience.
Learning From Tree Rings: An Interview With Nicole Davi
A dendrochronologist explains how tree rings can teach us about our past, present, and future.
