Spotlight on: Seacology

When many people dream of the perfect summer vacation or holiday, visions of sandy beaches, crystal clear waters and lush forests come to mind. Islands are a home away from home for many travelers around the world but most people are unaware of the amazing biodiversity that island habitats support. This is where our partners at Seacology come in.
Seacology is an environmental nonprofit with the sole purpose of preserving the highly endangered biodiversity of islands throughout the world. In the last 400 years, the majority of the world’s plant and animal extinctions have taken place on islands. By working with indigenous island peoples, Seacology strives to find the middle ground between improving human life while maintaining the environmental integrity of islands habitats and species.
With a favorable year-round climate and isolation from large land masses, tropical islands support some of the most unique species on Earth. Here’s a sample of some of Seacology’s most recent projects, highlighting the endangered species they have helped to protect.

In exchange for a new community health clinic in Papua New Guinea, Seacology established a 988-acre no-take coastal marine conservation area providing a permanent sanctuary for many island species including the Asian giant softshell turtle, an easily recognizable species with its broad head and eyes close to the tip of its snout.

The stunning bowl coral is just one of the many corals, fish, crabs and other marine species safely protected for the next 10 years near the island of Tonga in the South Pacific. Through another agreement between Seacology and local island peoples, 368 acres of a critical marine habitat reserve are protected into the next decade in return for an updated community hall building.

Ocean life in shocking decline

The world’s oceans are in a “shocking” state and marine species may face an unprecedented extinction event, an international panel of experts has warned.

The many threats to the world’s coral reefs include increasing ocean temperatures, which can cause coral ‘bleaching’, as shown in this Acropora species.

The panel was brought together by the International Programme on the State of the Ocean (IPSO) and involved scientists from across a range disciplines. It was the first to consider the cumulative impacts of the pressures facing the oceans, including pollution, ocean acidification, ocean warming, over-fishing and hypoxia (reduced oxygen levels).

Rapid pace of change

“The findings are shocking,” said Alex Rogers, Scientific Director of IPSO and a professor of conservation biology at Oxford University. “As we considered the cumulative effect of what humankind does to the oceans, the implications became far worse than we had individually realised… almost right across the board we’re seeing changes that are happening faster than we’d thought, or in ways that we didn’t expect to see for hundreds of years.”

Overfishing has brought species such as the southern bluefin tuna to the brink of extinction.

These rapid changes include the melting of the Greenland and Antarctic ice sheets, sea level rise, and the release of methane trapped in the sea bed. More worrying is how different threats are acting together in ways that had not previously been recognised, their combined effects being worse than each threat alone.

For example, some pollutants have been found to stick to the surfaces of tiny plastic particles in the ocean, increasing the amounts of these pollutants being consumed by marine creatures. Global climate change, ocean acidification, pollution and overfishing are also working together to increase the pressures on the world’s coral reefs, many of which are now in severe decline.

Sixth mass extinction?

The combined effects of these stresses mean that ocean ecosystems are unable to recover, being constantly under attack from multiple threats. The panel concluded that not only are we already seeing significant declines in marine species and habitats, but that we now face losing species and entire marine ecosystems, such as coral reefs, within a single generation.

Life on Earth has gone through five “mass extinction” events in the past, and human activities are now thought to be causing a sixth such event. The panel’s report said that the combination of threats to the ocean is creating the same conditions found in every major extinction in Earth’s history. Levels of carbon dioxide being absorbed by the ocean are already far greater than at the time of the last mass extinction of marine life, some 55 million years ago. The rate of the ocean’s degeneration is also far greater than anyone had predicted.

Conserving the world’s oceans

The panel’s conclusions will be presented in a report at the UN headquarters in New York later this week, when discussions will take place aimed at reforming governance of the oceans. The report calls for urgent measures to better conserve ocean ecosystems, and in particular to improve governance of the largely unprotected high seas.

IPSO’s immediate recommendations include stopping exploitative fishing, especially on the high seas where there is little effective regulation. It also recommends mapping and then reducing pollutants, such as plastics, fertilisers and human waste, which are entering the oceans. In addition, sharp reductions need to be made in greenhouse gas emissions, and research is urgently needed into ways of reducing carbon dioxide in the atmosphere.

Like many marine species, the green turtle faces a range of threats. This species is classified as Endangered by the IUCN.

One of the report’s co-authors, Dan Laffoley, Marine Chair of IUCN’s World Commission on Protected Areas, and Senior Advisor on Marine Science and Conservation for IUCN, admitted that the challenges were vast. “But unlike previous generations, we know what now needs to happen,” he said. “The time to protect the blue heart of our planet is now.”

Northern Line Islands Expedition

Northern Line Islands

In 2010 and 2011, Dr. Enric Sala and a team of scientists traveled to the northern Line Islands in the North Pacific. There, the crew discovered a marine world that science never knew existed—one that hadn't yet been explored and damaged by humans, with an ecosystem little changed from its condition hundreds of years ago.
"We started at an island with 10,000 people and very degraded marine life," Sala explains. "We continued to an island with 2,500 people, then to one with ten people, and finally to one with zero people and a virtually intact ecosystem. It was a trip back in time, from degraded to pristine."

5 Underwater Hot-Spots

 Summer is coming and with it, the need to go to the beach, swim or practice water sports. Adrenaline is the driving force behind this exciting hobby. For the water sports fanatics, we have rounded up 5 of the best locations to practice snorkelling, diving, swimming or surfing.

1. The Great Barrier Reef is the world’s largest coral reef system that contains over 2,900 individual reefs and 900 islands. Located in the north-east coast of Australia, the Coral Reef is the only organic collective that can be seen from the Earth’s orbit. It has been declared a World Heritage site in 1981, also being rightfully considered one of the wonders of the natural world. The idyllic islands, sights and coral cays cover over 300,000 square kilometres. The abundant wildlife is probably the best reason to visit this amazing natural wonder: it is house to more than 1500 species of fish, 4000 types of mollusc and more than 200 species of bird life.

2.Located in the Sulu Sea, Palawan, the Philippines, the Tubbataha Reef Marine Park is a true marine sanctuary made up of two atolls. The reef lays on extinct underwater volcanoes, having an amazing pristine coral reefs set on a 100-m perpendicular wall. Apart from several lagoons and two spectacular coral islands, Tubbataha offers one of the best diving experience worldwide. It is an opportunity to explore the habitats of many fish colonies or see the endangered hawksbill sea turtles. Apart from the extensive marine wildlife, the Tubbataha Reef is also a bird sanctuary, home to tens of thousands of birds during their annual migrations.

3. Located near the town of Bouillante in Guadeloupe, the Jacques Cousteau Underwater Reserve offers the opportunity to snorkel and explore the vivid coral and marine wildlife or retreat on a beautiful black sand beach. The marine preserve encompasses several dive sites off the coast of Guadeloupe. Around the the area you can enjoy the National Park of Guadeloupe or the Botanical Gardens, packed with hiking trails, waterfalls and lush vegetation. Keep in mind that it is forbidden to take a piece of coral or bother a sea turtle.

4. The largest raised coral atoll on earth, Aldabra is comprised of four coral islands that surround the shallow lagoon. The atoll is locatyed in the Indian Ocean, and belongs to the Seychelles. Protected from man’s influence, Aldabra is a major wildlife refuge, being home to 152,000 giant tortoises – the world’s largest population of this reptile. The tortoises weigh a quarter of a ton and can often live pass 100 years. Due to the fragile flora and fauna, the atoll receives around 1000+ visitors a year. Aldabra is recognized as an endemic bird area and has been a UNESCO World Heritage Site since 1982.

5. Named one of the Seven Underwater Wonders of the World, the Galapagos Islands are one of the best scuba-diving destinations you can come across. The main dive hotspots are Wolf Island and Darwin Island, two eroded volcanos located on a volcanic ridge. The islands are inhabited by sea birds and are home to diverse marine species, being seldomly visited, except by scientists and scuba divers. They are famous for the “Vampire” finch, a species of the sharp-beaked ground finch that pecks at nesting boobies, drinking their blood. Also, Darwin Island is the only one in the archipelago where the sooty tern breeds. All things connsidered, the two attractions in the Galapagos Islands are one of the hottest diving hotspots in the world.

Undersea Explorer

Using state-of-the-art underwater photography, scuba divers travel the world's oceans, lakes, and wateways on intriguing journeys to rarely seen strange and unusual underwater kingdoms.

Bermuda Reef Explorer, Hamilton

Once in Bermuda, whether it be for work or vacations, one of the must-do activities is to explore the amazing reefs that surround the island.
One of the best ways to do so is without doubts to take a tour on the BERMUDA Reef Explorer, Hamilton. It is Bermuda’s largest glass-bottom boat with a length of 70 feet and and a beam of 20 feet.
Owned by Captain Michael Gladwin who bought it from Bermuda Island Cruises and has over 25 years of marine experience, the boat can hold up to 150 passengers in two large open deck and a lower deck where you will find the glass-bottom. Since she was given a major refit in 2007, the Reef Explorer has a new dive platform at the rear.
There are different cruises available, from a glass-bottom tour to a snorkel adventure, a fun tour of Bermuda and a pirate party adventure.
If you ever wanted to discover what lays beneath the ocean surface without getting wet, then the glass-bottom adventure is definitely for you. The two-hour tour takes you Turtle Cove to see Atlantic Green Turtles living on the sand flats. As the boat dwells above them, you can observe them by the glass-bottom as well as seeing them really close when they surface next to it.
On the way, you will stop by the Vixen, a nearly-submerged shipwreck where you can feed hundreds of fish. One arrived to destination, the lower floor hatches are removed to reveal the glass-bottom and the wonderful and coloured coral reefs and many species of fish.
During the whole trip, Captain Michael Gladwin will share with you his knowledge and provide you with commentaries and many interesting facts about Bermuda. The Captain is for many passengers the plus of the Reef Explorer tours.

How tourism—even green tourism!—is killing the world’s reefs

Coral reef off the Egyptian coast

All over the planet—from the Caribbean to Australia’s coasts—coral reefs are withering from the stress swimmers and tourism-related chemicals impose on them. According to WarmIslands.com, during the last 10 years alone the Caribbean’s reefs have been under strenuous attack.

The culprits:

• Snorkeling and diving – swimmers astonished by the reefs’ beauty touch the fragile corals, causing serious damage. SOLUTION: stay away from those reefs! And if for whatever reason you find yourself down there, hands off, kids!
• Sunscreen – chemicals in the sunscreen dissolving off swimmers’ skins intensifies the decline of coral populations. SOLUTION: choose biodegradable sunscreen or wear a t-shirt.
• Disturbed sediment – unnaturally strong currents (caused by swimmers, yachts, motorboats, and so on) can alter sediment and provoke the diaspora of animal life as the animals lose their home. Another consequence is sand settling onto coral formations. SOLUTION: stay off those boats!
• Anchors of motorboats, yachts, etc. – these can destroy corals and thereby their entire ecosystem, which results in animals losing their homes. SOLUTION: just say no!
• The collection of specimens – despite the seemingly infinite abundance of marine life, the removal of species is not only detrimental to the ecosystem, but may also result in the accidental removal of rare and endangered species. SOLUTION: refrain from collecting any specimens and do your best to discourage others from doing so.
• Increase in sedimentation – as tourism grows, so does the construction of hotels and other developments used to accommodate travelers. With construction comes pollution in the form of noise, contaminated air and water, and copious sedimentation both natural and synthetic. Higher amounts of sedimentation close to the shore encourage ocean species to move farther offshore, where lower levels of nutrients are available for their consumption and they are more vulnerable to the pernicious attacks of motorboats, etc. SOLUTION: consider going somewhere else for the holidays, or remain strictly green and encourage others to follow your lead – which should be a perpetual tactic for us eco travelers anyway!
• Waste – more people equals more waste. While proper waste disposal methods are usually available, many tourists are ignorant of environmentally friendly ways to dispose of their waste. Another problem is the myriad tourists who just don’t care about the environment enough to change their destructive habits. Their garbage then winds up floating on the water and sticking to coral reefs. SOLUTION: speak up when you see someone littering and kindly point them in the right direction.
• Pollution – While some vacation spots aren’t located within industrialized areas, it is usually inevitable that pollutants will be released into the air, land, and water in the forms of fuel, oil, paint, sewage, and so on. SOLUTION: go green or don’t go at all!

It is imperative that we continue to raise awareness about green tourism to inspire respect for our precious planet. As we continue to devise new ways to mitigate humans’ effects on our planet, we owe it to ourselves to compassionately educate those around us.
