Statement by the Caribbean Tourism Organization on the influx of Sargassum seaweed

CTO logoBRIDGETOWN, Barbados, Tues 11 Aug 2015 – The seasonal influx of Sargassum seaweed on Caribbean beaches has got the attention of the Caribbean Tourism Organization (CTO) and tourism policymakers and practitioners across the region.

Sargassum is a natural occurrence believed to originate in the Sargasso Sea, a two million-square-mile body of warm water in the north Atlantic near Bermuda, although some scientists believe the current influx was brought into the Eastern Caribbean through the North Brazil Current and because it thrives in warm, nutrient-rich water, the Sargassum simply spreads throughout the region.

It is an unwelcome visitor which can be uncomfortable and which takes away from the beach experience for our guests.

The CTO and our Caribbean partners are treating this matter seriously and with urgency. We have engaged a number of regional and international institutions in our attempts at finding solutions, among them, universities.

A number of theories have been advanced as to the cause of the latest influx, and myriad suggestions put forward for tackling the issue. We will be participating in a symposium being led by the University of the West Indies (UWI) next Monday, August 17th “to crystallize these myriad ideas and theories into workable solutions that can be implemented immediately to address our situation.” We are optimistic that meaningful solutions will emerge.

Among our CTO member-countries the issue differs significantly from one set of circumstances to another, as does the level of the incursion. Even in destinations which are at risk, not all beaches have been affected; in some cases it’s just on the windward coast and not the leeward.

But many seem to agree that what’s needed is a deeper understanding of how to tackle the issue collaboratively, with key stakeholders, public- and private-sector, contributing to the discussion. This is what the CTO is encouraging; this is what we are involved.

The Caribbean has countless attributes which makes our region a most desirable holiday destination. Our history, culture, cuisine, music, hiking, diving, bird-watching, festivals, etc, all make for unforgettable experiences. However, for most of our members, the beach is an integral part of this experience, the pristine nature of which we are proud. We are aware that the influx of sargassum can impact this aspect of our product and we will be at the centre of efforts to find a regional solution.

Stinking seaweed that smells like rotten eggs that’s blighting Caribbean resorts labelled ‘natural disaster’ as tourists cancel their holidays

Decaying seaweed washing up on the Caribbean coast that smells like rotten eggs has been labelled a ‘natural disaster’ after tourists cancelled their holidays because of it.

The picture-perfect beaches and turquoise waters that people expect on their visits to the Caribbean are increasingly being fouled by mats of seaweed that attract biting sand fleas.

Clumps of the brownish seaweed known as sargassum have long washed up on Caribbean coastlines, but researchers say the algae blooms have exploded in extent and frequency in recent years.

The 2015 seaweed invasion appears to be a bumper crop, with a number of shorelines so severely hit that some tourists have canceled summer trips and lawmakers on Tobago have termed it a ‘natural disaster.’

From the Dominican Republic in the north, to Barbados in the east, and Mexico’s Caribbean resorts to the west, officials are authorizing emergency money to fund cleanup efforts and clear stinking mounds of seaweed that in some cases have piled up nearly 10 feet high on beaches, choked scenic coves and cut off moored boats.

With the start of the region’s high tourism season a few months away, some officials are calling for an emergency meeting of the 15-nation Caribbean Community, worried that the worsening seaweed influx could become a chronic dilemma for the globe’s most tourism-dependent region.

‘This has been the worst year we’ve seen so far. We really need to have a regional effort on this because this unsightly seaweed could end up affecting the image of the Caribbean,’ said Christopher James, chairman of the Tobago Hotel and Tourism Association.

There are various ideas about what is causing the seaweed boom that scientists say started in 2011, including warming ocean temperatures and changes in the ocean currents due to climate change. Some researchers believe it is primarily due to increased land-based nutrients and pollutants washing into the water, including nitrogen-heavy fertilizers and sewage waste that fuel the blooms.

Brian Lapointe, a sargassum expert at Florida Atlantic University, says that while the sargassum washing up in normal amounts has long been good for the Caribbean, severe influxes like those seen lately are ‘harmful algal blooms’ because they can cause fish kills, beach fouling, tourism losses and even coastal dead zones.

‘Considering that these events have been happening since 2011, this could be the ‘new normal.’ Time will tell,’ Lapointe said by email.

The mats of drifting sargassum covered with berry-like sacs have become so numerous in the Caribbean Sea and the Atlantic Ocean they are even drifting as far away as to West Africa, where they’ve been piling up fast in Sierre Leone and Ghana.

Sargassum, which gets its name from the Portuguese word for grape, is a floating brownish algae that generally blooms in the Sargasso Sea, a 2 million-square-mile body of warm water in the North Atlantic that is a major habitat and nursery for numerous marine species. 

Like coral reefs, the algae mats are critical habitats and mahi-mahi, tuna, billfish, eels, shrimp, crabs and sea turtles all use the algae to spawn, feed or hide from predators.

But some scientists believe the sargassum besieging a growing number of beaches may actually be due to blooms in the Atlantic’s equatorial region, perhaps because of a high flow of nutrients from South America’s Amazon and Orinoco Rivers mixing with warmer ocean temperatures.

‘We think this is an ongoing equatorial regional event and our research has found no direct connection with the Sargasso Sea,’ said Jim Franks, senior research scientist at the University of Southern Mississippi’s Gulf Coast Research Laboratory.

Whatever the reason, the massive sargassum flow is becoming a major challenge for tourism-dependent countries. In large doses, the algae harms coastal environments, even causing the deaths of endangered sea turtle hatchlings after they wriggle out of the sand where their eggs were buried. Cleanup efforts by work crews may also worsen beach erosion.

‘We have heard reports of recently hatched sea turtles getting caught in the seaweed. If removal of seaweed involves large machinery that will also obviously cause impacts to the beaches and the ecosystems there,’ said Faith Bulger, program officer at the Washington-based Sargasso Sea Commission.

Mexican authorities recently said they will spend about $9.1 million and hire 4,600 temporary workers to clean up seaweed mounds accumulating along that country’s Caribbean coast. Part of the money will be used to test whether the sargassum can be collected at sea before it reaches shore.

Some tourists in hard-hit areas are trying to prevent their summer vacations from being ruined by the stinking algae.

‘The smell of seaweed is terrible, but I’m enjoying the sun,’ German tourist Oliver Pahlke said during a visit to Cancun, Mexico.

Sitting at a picnic table on the south coast of Barbados, Canadian vacationer Anne Alma said reports of the rotting seaweed mounds she’d heard from friends did not dissuade her from visiting the Eastern Caribbean island.

‘I just wonder where the seaweed is going to go,’ the Toronto resident said one recent morning, watching more of mats drift to shore even after crews had already trucked away big piles to use as mulch and fertilizers.
