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 between bay and sound sediments, but that raises new questions about what’s going on in the Bay to account for those.
PROVIDENCE, R.I. [Brown University] — Rhode Island’s geography is famously small, but new measurements of the nitrogen cycle in its waterways suggest that even over a small distance, differences can be huge. Scientists report that the nitrogen-converting process anammox is almost completely absent in Narragansett Bay, even though it is going strong in Rhode Island Sound only 15 miles off the coast.
