What Is Sargassum Seaweed?

If you’ve ever been to the beach, you’re probably at least slightly familiar with seeing seaweed in the sand. It’s never very much, so why should this seaweed in Key West be any different? Before we get into why it’s problematic, let’s get to the bottom of what sargassum is.

Sargassum seaweed originates from brown algae found in the waters of the Sargasso Sea of the Western Atlantic Ocean. That brown algae collects together to form a seaweed that, when inspected closely, has a very intricate leaf pattern with small, pearl-like balls of air nestled within the brambly seaweed.

These air-filled sacs make the seaweed float, and as it works its way through the nutrient-rich waters flowing into the Atlantic Ocean from the Amazon and upwelling currents from West Africa, the sargassum forms into a huge mass headed right for the east coast of Florida. This floating mass is now what we call the Great Atlantic Sargassum Belt.

What Is The Great Atlantic Sargassum Belt?

Once all the sargassum floats together to form the huge mass known as the Sargassum Belt, it collects over time to create a 5,000-mile-long island-like mass of sprawling seaweed stretching from West Africa toward the Caribbean Sea. This large mass of brown seaweed is constantly moving on the surface of the water, so it never connects to the sea floor, which acts as a floating habitat.

Some of the creatures that find a safe haven within this massive web of seaweed include:

  • Crab
  • Shrimp
  • Tropical Fish
  • Marine Birds

Is Sargassum Seaweed Dangerous Or Just A Nuisance?

As sargassum washes ashore every year in Key West, locals and visitors alike are primarily annoyed by the smell of the sargassum quantity on the beach. This giant blob of seaweed breaks up along the shore to create a mess on public beaches in Monroe County, but there’s not too much danger involved.

Decaying sargassum starts to emit the gas hydrogen sulfide as it rots in the sun, and while it’s mostly bothersome for its potent stench of rotten eggs, people with respiratory issues, including asthma, should be mindful around the seaweed. Not only can this emission give you breathing problems, but it could potentially make you feel weak and ill if you aren’t careful.

Another annoyance sargassum seaweed brings is its hindrance to swimming! It’s very uncomfortable swimming in and around sargassum as its winding web of floating seaweed makes it hard to navigate through. If there’s a significant sargassum quantity in the water, it’s best to stay out until it can be cleaned up.

Does The Sargassum In Key West Play A Significant Role With Wildlife?

The stinky seaweed that floats in from the Gulf of Mexico each season turns from a flourishing habitat to a potential death trap for many sea turtles in the Caribbean Sea. As the sargassum washes ashore, it creates a tangled-up mess along the water that makes it hard for nesting mama turtles to make it to the sand to hide their eggs. She can also get tangled in it as she pursues her matronly mission, which can create its own set of problems.

If the mother turtle does successfully nest her eggs in the sand, once the babies are born, the clots of seaweed make it challenging, if not impossible, to reach the water, which can create a deadly problem for the population of beloved turtles in the Caribbean Sea.

Does Anyone Do Anything About The Seaweed Problem In Key West?

The short answer to that question is yes! The city of Miami and Monroe County employ beach cleaning contractors that travel around the east coast and the coast of the Gulf of Mexico to dispose of the putrid decaying sargassum.

Some beaches like South Beach and Higgs Beach work to make sure their beaches are cleaned twice a day for the comfort of visitors.

When Is Sargassum Seaweed The Worst In Key West?

While the seaweed shows up from the Gulf of Mexico around June each year, it always piles up the most between July and August. If you’re looking to schedule your trip to Key West when it’s least likely to be consumed with seaweed, you’ll want to make plans to arrive between October and May.

The cooler months of the year might not always be ideal for a beach lover, but you can almost guarantee you won’t have to worry about sargassum or the smell of rotten eggs at all during your stay.
