Proposed Pitcairn Islands Marine Reserve

Have you ever heard of the Pitcairn Islands? As an ocean lover, I was surprised that I had never heard of this amazing chain of islands in the southern Pacific Ocean; their closest neighbor, New Zealand, is a distant 2,800 miles (4,500 kilometers) away.pitcairn-island-location-on-map240x180 A British Overseas Territory, humans only inhabit one of the four islands and the waters surrounding them are teaming with fish, marine mammals, turtles, and pristine coral reefs. Boasting some of the clearest seawater in the world, the remote location of this area has helped keep it protected and allowed sea life to thrive.

Since early 2011 the Pew Environment Group’s Global Ocean Legacy project has been working with the Pitcairn islanders on the idea of establishing a large-scale marine reserve within their waters. In March of 2012, the National Geographic Society and Global Ocean Legacy teamed up to perform a scientific expedition to Pitcairn and surveyed the underwater landscape. Following this expedition, the islanders of Pitcairn joined with the Pew Environmental Trust and the National Geographic society to call upon the British government for the establishment of a large highly protected marine reserve within the exclusive economic zone (the area of ocean from the shoreline out to 200 nautical miles) of the Pitcairn Islands.

Despite the fact that researchers have only just begun to explore this area, they have already identified 1,249 marine species. This population includes 22 species of whales and dolphins, 2 sea turtles, 365 species of fish, and 48 marine species already classified as critically endangered, endangered, vulnerable, or near threatened.

If approved, the Pitcairn marine reserve would be the largest highly protected marine reserve in the world encompassing over 834,000 square kilometers. As a large no-take reserve, the local population would be able to continue the low impact traditional sustenance fishing that they do today, but large commercial fishing would be restricted. The local economy would likely benefit from the increased interest in scientific research, conservation, and tourism. Last month, the Deputy Mayor of Pitcairn visited London in order to champion their cause, they returned home with high hopes that the British government will endorse the proposed marine reserve area.

Ocean Revival

I’m beginning to believe there may be seawater in my veins. My earliest childhood memories have me gazing out over the vast Pacific Ocean, tide pools were my playground, and my bus stop for school stood on the side of scenic Highway 1 on the California coast between Carmel and Big Sur. As an adult, I confess that spend a disproportionate amount of time researching and dreaming of amazing travel destinations, almost all of which seem to be located on the water. A recent search led me to a new underwater park in Southern Portugal… yes, you read that correctly, an underwater park.

ocean-revival-is-a-nonprofit-organizationCreated by the MUSUBMAR Association, a non-profit association created to promote and develop the underwater tourism industry in Portugal, the Ocean Revival project is the worlds largest artificial reef structure. In accordance with OSPAR Convention rules, four decommissioned vessels from the Portuguese Navy were cleaned of all environmentally hazardous materials or dangers for divers. The ships were then deliberately sunk, one-by-one, to create an artificial reef in an area with ideal conditions for the proliferation of marine life.

oceanrevival-padiCurious about artificial reefs and their affect on the environment, I decided to dig a little deeper. In an article by the National Geographic Society, University of Tel Aviv marine biology professor Yehuda Benayahu, who studies artificial reefs in the Red Sea, stated, “When a ship sinks, it immediately becomes shelter for marine organisms. Such habitats provide new food sources, greater protection for juveniles, and more space for settlement.” The artificial reefs that are a part of Dr. Benayahu’s research studies include sunken ships ranging from 16 to 130 years in age. Many of the artificial reefs are located near natural reefs, enabling the scientists to compare the two environments at various stages of reef development.

With the steadily increasing popularity of scuba diving and the increasing accessibility of recreational diving, many scientists have expressed concerns about the strain it may cause coral reefs and their inhabitants. U.S. National Oceanic and Atmospheric Administration scientist Mark Eakin points out, “The presence of artificial reefs as an alternative dive site can reduce the stress placed on the natural reefs… in many cases, artificial reefs will decrease the total dives on natural reefs.”

Well-planned artificial reefs, like the Ocean Revival site, can actually be beneficial to the environment.

sealifeonshipThe Ocean Revival project was founded on “the belief that sustainable tourism is a viable way to protect bio-diversity and the preserve the environment.” The dive site, which opened in late 2012, is located in an area of southern Portugal called the Algarve. This area is unique in that it is situated where the waters of the Mediterranean Sea and the Atlantic Ocean mingle. Good weather and clear, calm water prevail for most of the year and as a well-established vacation area there are a number of tourist attractions for those who don’t scuba dive. Dive operators in the area offer a broad range of services from introductory dive certification classes for new divers to less structured tours for advanced divers.
