An unusual seaweed phenomenon, known as the ‘seaweed blob’, has recently caught worldwide attention due to its enormous size and growth rate. The ocean’s concerning lack of oxygen, combined with acidification and warming temperatures, provide the perfect storm for the seaweed blob’s lengthening reign. Reports on the severity of the situation suggest that an entire mass of seaweed, roughly the size of the state of Texas, has affected several areas of the U.S. Gulf Coast and is now making its way towards the Florida coastline. It is estimated that the seaweed blob is now about 200 miles away from the Sunshine State shores.
The ‘seaweed blob’ is made up of a particular type of bacteria, sargassum, which commonly laces the ocean around the Gulf of Mexico. In the past, the accumulation of this seaweed was managed through natural disturbances such as storms or coastal circulation, which broke up the continuous seaweed islands so they remained on the smaller side. The size of this particular bloom, however, has sparked curiosity and concern amongst marine biologists and government agencies in Florida.
Florida’s fish and wildlife have likely taken on the most damage during this event. Sea urchins, turtles, and crabs are deprived of oxygen while swimming through this deep, thick brown seaweed. In addition, increased concentrations of sargassum have led to an increase of jellyfish swarms across the affected regions. The negative effect that this seaweed blob has had on life in the sea is undeniable and experts state that the impact will be felt for years to come.
In an effort to prevent further harm, the Florida Fish and Wildlife Conservation Commission has applied a multi-search approach which includes monitoring the seaweed levels near the shore and physically removing it from the shoreline and coastal areas. In addition, studies suggest that another strategy for keeping this seaweed under control is to use innovative methods such as aquatic robots as a way to contain it without stressing the environment. It is important to note that despite recent efforts, the seaweed blob continues to linger.
Although great strides have been made to keep the seaweed blob from entering Florida’s waters, news of its impending arrival is causing many locals to worry. Beachgoers especially have a growing sense of uncertainty over the safety of beaches for their families and friends. It is easy to understand why citizens of the state are worried, as any type of seaweed has the potential to make fun summer days unbearable.
In conclusion, many experts are cautioning people in Florida and neighboring states to be mindful of the ‘seaweed blob’ and its potential effects on the environment and the ocean life that lives there. The future of the Florida coastline remains a waiting game as the seaweed blob inches closer to its intended destination.
Sargassum Seeds
Sargassum, the main culprit behind the seaweed blob, is a type of brown seaweed commonly referred to as ‘oarweed’. Its presence in the gulf of Mexico is nothing new, and is essential to the underwater environment. The seaweed stores carbon and serves as a habitat for marine life, aiding in the development of smaller organisms such as larvae and plankton. The seaweed is so named because it typically grows in the ‘Sargasso Sea’, a body of water between the Atlantic, Caribbean Sea, and Gulf of Mexico.
Sargassum begins its lifecycle as tiny microscopic seeds which float along ocean currents until they eventually attach themselves to rocks and other solid surfaces where they can grow and reproduce. These tiny seeds, known as sporophytes, require no sunlight or fresh water for development and have helped the seaweed to quickly spread across large areas of ocean water in a few short weeks.
The growth of sargassum across the Gulf of Mexico has been described as a ‘perfect storm’, as the combination of ocean acidification, warming ocean temperatures, and poor circulation are all contributors to its unprecedented growth. The reality is that, unless steps are taken to control the growth, sargassum will continue to expand and threaten life and property all along the coast of North America.
The Potential Threat to Tourism
The impacts of the seaweed blob are not limited to marine life. As the seaweed floats up onto the shoreline it can block access to the beach, clog waterways, pollute the air, and reduce visibility in the water. Florida’s economy and tourism industry could suffer a major setback if the seaweed blob hits its shores.
The truth is, Florida has become a popular tourist destination for much of the world. The state’s ecosystem is so diverse, there would be a major risk of destruction to coral reefs, seagrasses, and even some of Florida’s many species of fish. If the seaweed blob enters Florida, it could put an end to the tourism industry and the livelihoods of many people who depend on it.
The risk to the environment is too great to ignore. Government agencies must take steps to protect the beaches and coastline before the seaweed blob reaches their shores, if, indeed, it makes the journey. In the meantime, citizens and tourists should be cautious of their environment, and should remain vigilant for any signs of the seaweed blob.
Eco-Friendly Solutions
In order to protect the ocean from further damage, governments and conservation organizations are looking for eco-friendly strategies that can be used to combat the seaweed blob problem. Scientists are now focusing on the development of unmanned submarines that can monitor and collect sargassum from the deep sea before it reaches the coast.
These submersible robots, which are designed to withstand deep sea pressure and currents, will have the ability to collect the seaweed without doing damage to the underwater ecosystems. In addition, the robots will be able to move beyond the waters of Florida, allowing scientists to monitor currents in remote locations and predict where the algae might spread next.
Organizations are also experimenting with ways to recreate coastal currents, which would be used to drive the seaweed away from Florida shores. These strategies would harness the power of tides and winds to limit the amount of sargassum that settles on the coastline. While these projects are still in the research and testing stages, the intention is to create a long-term solution that will protect the ocean and beaches from any future algae blooms.
Addressing the Underlying Problem
The most troubling aspect of the seaweed blob situation is that its growth rate has been largely caused by human activities in the first place. Nutrient-rich runoff from fertilizers, as well as untreated sewage, have led to increasing levels of oceanic acidification, which has ultimately enabled the seaweed to feed and grow in such large numbers. This reality highlights the need for businesses and individuals to do their part in reducing their contribution to global climate change.
Governments should also consider introducing regulations and laws against polluting activities in the ocean. In addition, citizens should take the initiative to reduce their carbon footprint and practice environmental stewardship. This includes using natural fertilizers, composting, and avoiding single-use plastic wherever possible. Taking such measures can ultimately help to stem the tide of oceanic acidification and prevent seaweed blooms from ever reaching such extreme proportions.
Creating Awareness
It’s important to remember that every individual has the power to make a difference. A concerted effort from citizens throughout the country can create a ripple effect on a global scale. Raising awareness on the impacts of the seaweed blob is a great starting point, and can lead to shifts in local and federal policies which will prevent similar events from continuing to occur in the Gulf of Mexico and other regions.
Informing the public of the issues plaguing the ocean such as ocean pollution, climate change, and overfishing is key to ensuring a healthy future for the ocean’s ecosystems. It is only through raising awareness and making small changes in our own lives that we can help to ensure the health and safety ofFlorida’s biodiversity.
