In the center of the Atlantic Ocean lies the Sargasso Sea. The brown seaweed, Sargassum, gives the Sea its name. However, in the past decade this belt of Sargassum has been exploding. During certain seasons, the Sargassum belt has expanded from West Africa to the Americas. Beached seaweed has led to numerous problems and concerns for much of the Caribbean, Central America, and South America. Research led by Dr. Mengqiu Wang from the University of South Florida used previous data to determine what makes these seaweeds take over the ocean in order to better predict when these blooms may occur.

However, evidence suggests that some cover crops may in fact release nutrients, instead of keeping them out of the water. One study explores whether five types of cover crops release phosphorus, and how that may impact water quality in the important Great Lakes region.

Copepods are tiny, cosmopolitan marine creatures that are a vital food source for fish, birds, and many more. In the vast ocean, many copepods find their food, algae, by scent, as some algae give off a sulfur smell from the compound dimethyl sulfide. This study set out to test if copepods would be more likely to eat microplastics that were infused with this sulfur-scented compound.
