The islands that make up Bermuda lie just west of the center of the Sargasso Sea in the northern Atlantic Ocean. Further north and a bit removed from its Caribbean cousins, Bermuda has nonetheless enjoyed a fairly healthy tourist trade and is home to a variety of sea life It's aquatic abundance is due in no small part to the Sargasso Sea with its large floating mats of sargassum seaweed which provides a haven for many juvenile fish species.
The Pew Environment Group, as part of its Global Ocean Legacy program, is working to have a national marine park established in Bermuda, similar to marine parks found in other island nations.
“Our goal is to work with the Government of Bermuda, non-government organisations and scientists to establish a very large, no-take marine reserve to protect Bermuda’s ocean habitat within its Exclusive Economic Zone [EEZ], which extends from the islands’ coastline out to 200 nautical miles, and is part of the Sargasso Sea,” said the Pew Environmental Group, which launched the marine national park scheme in 2010.
Such a marine park would not only protect Bermuda's coastal marine resources and contribute to an international effort to establish safeguards to protect at least 10 percent of the world's oceans (I know, 10 percent is not much, but it's a start), but it would also provide protection for the Sargasso Sea and its namesake seaweed.
There is quite a variety of sea life that call the floating sargassum home, from juvenile reef fish to young turtles, invertebrates, and all of the larger predators that might feed on the juvenile populations. And it's not just animals that you would expect to find living locally to Bermuda. There are species that travel great distances to use the sargassum as a breeding ground and nursery. As an example, scientists have documented eel species coming from rivers as far away as North America and even Europe to spawn within the sargassum. The young eels mature in the Sargasso Sea and ultimately migrate back to the rivers.
Six hundred and forty miles from the coast of North Carolina, Bermuda is also surrounded by deep water which provides for a variety of deep sea life, again ranging from small larvae right up to deep-diving whales.
Bermuda might seem a bit remote on the map but it is not immune to the threats of climate change and commercial fishing. The Sargasso Sea is home to tuna, dolphin, wahoo, billfish, sea turtles, and the Porbeagle shark (just recently passed over for protection by the ICCAT). And there are thirty-six species local to Bermuda that have been declared threatened on placed on the IUCN's Red List.
“Given this highly productive ecosystem, scientists, Bermudians and others are concerned about protecting this area from emerging threats, such as proposals to harvest Sargassum for biofuel,” said Pew.
As part of the Global Ocean Legacy program, Pew will be focusing on Bermuda as home to a marine park, as well as areas in the Indian Ocean, Australia's Coral Sea, Hawaii, the Mariana Trench and the waters surrounding Pitcarin - famed for the late-17th century mutineers from the HMS Bounty who came to the remote island from Tahiti.

Recently, the National Oceanic and Atmospheric Administration (NOAA) announced a letter of intent had been signed with the Bermuda Department of Environmental Protection to establish a sanctuary for humpback whales. This will be the third such sanctuary for Atlantic Ocean humpbacks - the other two being the Stellwagen Bank in Maine and the Santuario Mamiferos Marinos in the Dominican Republic.
There are five distinct populations of humpback whales in the North Atlantic: Maine (Stellwagen Bank), Nova Scotia, Greenland, Norway, and Iceland. In the north, the whales feed but when breeding season approaches, they head south to the Caribbean. These migratory patterns are of considerable importance to researchers as the better they understand them, the more effective the management and regulatory policies can be made to protect them. Some of these migratory highways are known to cross established shipping lanes, and that has resulted in collisions with ships which produce serious injury or death.
As an example, after studying whale movements based on sightings over a 20 year period, a proposal was recently made to move shipping northward by 12 degrees; the anticipated result being a drop in strikes by ships of over 80 percent.
Both the proposed Bermuda and the Dominican Republic sanctuaries are considered "sister" sanctuaries to Stellwagen Bank. In the Caribbean, the various whale populations mingle, guaranteeing a good mix of the gene pool, before all heading back to their respective northern locations. While more sanctuaries are being sought in and around the Dominican Republic, the Bermuda sanctuary is less in the specific breeding zone than it is a spot along the route.
Positioned just south of halfway along the whales' journey, the sanctuary would afford researchers the opportunity to study the whales during migration, provides protection within the migratory corridor, and even affords Bermuda the opportunity to generate additional tourism dollars through whale watching excursions.
"This is a first step in putting together conservation stepping stones throughout their migration. The expansion of our Sister Sanctuary Program will play a powerful role in protecting endangered humpback whales, and the opportunity for international cooperation in marine conservation is invaluable," said Nathalie Ward of the Stellwagen Bank National Marine Sanctuary.
Humpback whales - recognizable by their long pectoral (front) fins and famous for their possible communicating via long, ethereal "songs" - are found in basically all of the world's oceans. While protected by many nations, they have been hunted by a few of the remaining whaling nations, in particular Japan, who takes them under the guise of scientific research, a shameful loophole in the whaling moratorium regulations of the International Whaling Commission (IWC). The current population of humpback whales is estimated at around 80,000, down from a pre-whaling population of around 125,000. That's a better situation than other species of whales and, in 2008, the IUCN changed the whale's listing regarding possible extinction from "Vulnerable" to "Least Concern."
Sounds like a slowly evolving success story but there is still much that we don't know about these immense but graceful marine mammals, so the work goes on and whale advocates remain ever vigilant.
