Tides and microbes transform nitrogen where streams and the ocean meet

Enormous amounts of excess nitrogen hit water bodies all over the globe, including the U.S., due to runoff from agricultural and other human activities. This nitrogen can cause dead zones and harmful algal growth. Before it reaches the ocean, microbes can process and remove some of it from stream sediments, connected aquifers and tidal freshwater zones.  Thanks to this process, coasts can have a decreased likelihood of harmful algal blooms.  Keeping coastal waters clean is important for many reasons, including the fact that about 60% of the U.S. population lives on coasts. But despite the importance of these nitrogen processes, researchers have not fully investigated how they work.

Climate, nutrients and the future of hypoxia in a Chesapeake Bay tributary

The Chesapeake Bay is the site of recurring seasonal dead zones: areas of low dissolved oxygen where aquatic life struggles to survive if it can at all. In 2020, a dead zone in the Maryland portion of the bay was one of the smallest since 1985, when record keeping began. The hypoxic area in the Virginia portion of the bay was smaller and briefer than many years previous. But the problem isn’t gone yet, and looking forward, climate change will play a big role in determining the size and severity of dead zones throughout the bay. It could make it harder to get hypoxia under control in some places.

Fecal bacteria rises with sea level on Texas beaches

As climate change lifts the sea level in the Gulf of Mexico, it’s lifting levels of enterococci bacteria on Texas’s beaches, too. New research out of the Gulf shows that high levels of enterococci bacteria, which come from humans and other animals and can cause disease, are correlated with proximity to large human populations and sea level rise and are increasing over time. The research highlights an area of growing concern for public health and safety on popular recreational beaches. While sea level is projected to continue rising, it’s not a guarantee that bacteria levels will as well.
