Mapping Ocean Wealth – Informing a Sustainable Ocean Economy

By Mark Spalding, marine scientist, The Nature Conservancy I’m a somewhat recalcitrant tweeter. I’m not quite sure whether it’s worth the effort, but last month I joined a trending topic, a first for me. I tweeted: #IAmAScientistBecause I want to explain to people how much we all NEED nature. It was honest, but I wondered…

States, Nations Announce Commitments Ahead of U.N. Climate Conference

Roughly six months before international leaders meet in Paris for a United Nations climate change conference, U.S. states and foreign nations are stepping forward with climate commitments. Canada, on Friday, pledged to cut its greenhouse gas emissions 30 percent below 2005 levels by 2030. California is joining a climate agreement with eight foreign nations and…

Time For An Oil Change

By Annie Reisewitz and Sarah Martin It’s been calculated that a tanker leaking a drop of oil every 10 seconds releases 60 gallons of petroleum oil into the world’s oceans every year. Water, now more than ever, has become a precious resource in need of protection. We are facing a number of looming water-related crises…

No Ice in Sight: Polar Bears Scrabble Onshore to Find Food

On June 4, 1773, English naval officers were dispatched on an expedition to the Arctic. Their goal was to locate a passage from the British Isles to the Pacific Ocean. Instead, on ice floes near Spitsbergen (Svalbard), Norway, they found polar bears. The explorers were the first Europeans to describe the bears as a distinct…

Last Ice Area Expedition Launches

Climate projections forecast the total disappearance of summer sea ice in the Arctic by 2040, with the exception of one place: the “last ice area,” north of Greenland and Ellesmere Island in Nunavut. This area will likely harbor the largest concentration of Arctic wildlife that depends on the sea ice edge for survival, including bowhead…

Diving the Site of JFK’s WWII Shipwreck

While looking for bumphead parrot fish, it was striking to think of the future U.S. president, roughly at our age, brought for a very different reason to this same remote Pacific island.

Americans Compete With Asian Local Markets For Blue Crab

Last week, I traveled to Kien Giang Province in southern Vietnam to learn about the Vietnamese blue swimming crab fishery. Since 2009 a cross-sector partnership of government agencies, exporters, and WWF-Vietnam have been dealing with contentious issues related to the sustainability of this stock. In discussions with this coalition, I was struck by the contrast…

Your plastic is getting to the Caribbean more often than you are, and it’s spoiling your next visit

Who left their trash behind on this remote Caribbean island? Then I realized. It wasn’t left. It arrived. An endless flotilla of refuse heedlessly sent from afar. It’s heartbreaking. The image of a lone bottle washing up on a remote tropical island is the clichéd stuff of literature, movies and New Yorker cartoons. But what…

The U.S. Supreme Court heard oral arguments this week in a challenge to the U.S. Environmental Protection Agency’s (EPA) consideration of cost impacts when developing the Mercury and Air Toxics Standard, (MATS) which are set to go into effect next month. At issue in the case is whether the Clean Air Act requires the EPA…

The Azores: First Witness to Global Marine Plastic Pollution

Having left Bordeaux on March 15, the Race for Water Odyssey arrived in the Azores on Friday afternoon, the location of the expedition’s first scientific analyses. It is estimated that 80% of pollution in the ocean is plastic. This debris has devastating effects on marine ecosystems and, as a consequence, on human beings. Entanglement, lacerations,…

Communities Leading the Way to Save Madagascar’s Mangroves

“About three years ago I noticed that the high tides were coming up into my rice fields, and taking the soil away with them. I’d never seen that before,” Philippe, a rice farmer from the village of Ambalahonko, tells me from under his wide-brimmed straw hat; something my fair-skinned and fine-haired self, unfortunately, did not…

Tracking a Group of Groupers

Guest post by Kristine Stump, postdoctoral research associate, Shedd Aquarium The beautiful and iconic Nassau Grouper was once one of the most important fishery species in the wider Caribbean, but due to heavy over exploitation is now scarce in many coral reef ecosystems throughout its native region. As mesopredators, groupers play a vital role in maintaining…

First Rules for Arctic Drilling Released

The U.S. Department of the Interior unveiled the first draft rules for offshore oil and gas exploration in the Arctic. The rules would require energy companies to clear a number of safety hurdles before being approved for drilling. “The Arctic has substantial oil and gas potential, and the U.S. has a longstanding interest in the…

Using Science to Empower Communities and Improve Marine Protected Areas in East Africa

By Jennifer O’Leary and Arthur Tuda When you think about East Africa, probably the first images that emerge are of large terrestrial animals like elephants and lions. Many people don’t know that East Africa has vibrant marine fishing communities and hundreds of miles of coral reefs. In a typical morning, you watch the sun rise…
