Fresh Water Below the Seafloor?
Using a new method to distinguish fresh water from oil or salt water, scientists are exploring beneath the continental shelf off New England to look for large pockets of trapped fresh water. This water may be continually filling from groundwater flowing from land or, alternatively, may have been left behind by ice ages glaciers.
