Record High Seaweed Influx Threatens Caribbean Resorts and Southern US Beaches
A significant amount of seaweed, totaling 37.5 million metric tons, was observed in May, marking a record high in the Atlantic basin since monitoring began in 2011. The University of South Florida's Optical Oceanography Lab reported the increase, warning that Caribbean resorts may soon be affected by the seaweed influx. While the spatial distribution patterns of Sargassum remained stable, the amount in each region notably increased in May, surpassing historical records in all areas except the Gulf of Mexico region.
Some beaches along the Gulf Coast and Florida have already seen small amounts of seaweed, raising concerns about potential larger blooms impacting beaches across the southern US. The Florida Keys typically experience widespread reports of seaweed during late spring, with more significant impacts expected across the Florida peninsula in the summer and fall. Photos and videos from eastern Puerto Rico depict waterways and beaches covered by seaweed, with the inundation likely to persist for months.
The exact causes of the growing seaweed blooms are not fully understood, but researchers suggest climate change, fertilizer runoff, and deforestation in South America as potential significant contributors. While the seaweed may not pose a significant risk to humans, it can have a substantial impact on the tourism industry, turning popular beaches into foul-smelling destinations that require extensive cleanup efforts. The Mexican government has planned to focus on discovery and containment efforts in waters surrounding popular beaches along the Yucatán Peninsula and Caribbean coast.
Seaweed typically washes ashore between April and October around the Yucatán Peninsula, but its increased presence in recent years, possibly due to climate change, has become a growing concern. The report anticipates continued growth in seaweed coverage throughout June, particularly in the western Caribbean and Gulf regions. Despite the challenges it poses, some marine life benefits from the seaweed buildup, as it provides food and refuge for small fish, crabs, shrimp, and other organisms.
In conclusion, the record-breaking amount of seaweed observed in May raises concerns for Caribbean resorts and beaches in the southern US. While the exact causes of the seaweed blooms remain unclear, efforts to monitor and manage the influx are crucial to mitigate potential impacts on tourism and marine ecosystems.
