Big things come in small packages, right? In this case, the small jar held by WHOI Chief Science Officer and Senior Scientist Dennis McGillicuddy contains sargassum, a free-floating brown algae that’s made headlines for inundating Florida’s coastline in recent years. These massive blooms may be caused by a combination of changing ocean conditions, including shifting currents, rising temperatures, and an influx of nutrients from both land and sea.
Rotting sargassum piles on Florida’s beaches generates unsavory odors that drive away beachgoers and demand costly cleanups.
Suffice it to say, I didn’t ask Dennis to open the jar.
