A research team with members from Spain, Argentina and Italy has found that intense deep sea trawling cuts seafloor biodiversity in half. In their paper published in Proceedings of the National Academy of Sciences, the team ...
A new study reports that anammox, a key process in the nitrogen cycle, is barely present in Narragansett Bay even though it's a major factor just a little farther out into Rhode Island Sound. Scientists traced that to differences ...
