This is SeaTalk: Ocean News from the University of Delaware.

UD’s marine researchers are tackling ocean and coastal issues here in Delaware, where they’re studying issues such as the water quality of Delaware’s inland bays and the health of our fisheries. But they also are conducting research in partnership with institutions as far away as China and on projects as remote as the Arctic and miles below the sea’s surface. One project is looking at the vulnerability of groundwater to sea-level rise in Bangladesh. That country, one of the most densely populated on Earth, relies on groundwater for everything from agriculture to drinking water, and if sea level rises, that resource could be at risk. Another study takes researchers to volcanoes on the ocean floor, where sprawling colonies of bright orange bacteria thrive on iron entering the water through cracks in the earth’s surface.
