Early on Monday morning, Shell announced that it would no longer pursue oil-drilling activities in the Chukchi Sea off the northwest coast of Alaska. Shell’s announcement has been a long time coming, and marks a major victory for all those who have opposed Arctic drilling as too risky and too much of a threat to the Arctic ecosystem and the planet’s climate.
Shell purchased its Chukchi Sea leases in 2008, but was precluded from drilling on its leases for many years. Among other things, legal challenges exposed flaws in the government’s environmental analyses and the BP Deepwater Horizon disaster resulted in a temporary restriction on Arctic drilling. In 2012, Shell finally received the green light to drill in the Chukchi Sea, but the company was woefully unprepared for the challenge: vessels were not ready, spill response equipment failed under testing, equipment spewed air pollution in violation of standards and one of its drill rigs was swept ashore in a storm on the way back to Seattle. In the end, Shell failed to complete a single well in 2012.
You have likely seen the pictures of albatross chicks chocking on plastics. These images are tough to look at and the death these birds suffer from ingesting plastics is gruesome and painful. Albatross consume a whole range of plastics that float in the ocean, from cigarette lighters, to toothbrushes to shards of plastics from a huge variety of other plastic products. As a conservation organization, Ocean Conservancy is deeply troubled by the impact of plastics on these magnificent birds. But how pervasive is this problem, really? A new paper in the peer-reviewed journal PNAS gives us a disturbing answer. It turns out plastics in seabirds is a very big deal. It is global, pervasive and increasing. And it has to be stopped.
In 2006, when I first heard about ocean acidification, I started running expeditions near underwater volcanoes in the Mediterranean where CO2 bubbles up through the sea floor, acidifying large areas for centuries. We have found similar ecosystem shifts at all the seeps, so I am now convinced that ocean acidification will bring change. In a recent article I attempt to put this topic into context, focusing on two major causes of change – the corrosive effects of CO2, and the way the extra carbon is used as a resource.
Here’s what we’ve noticed about the sea life around those natural CO2 seeps in the Mediterranean: algae seems to thrive, whereas animals with calcium carbonate shells—like plankton—dissolve away. We see a lot of brown seaweeds on the seafloor, and they often overwhelm slower-growing competitors like corals. Although life is abundant at CO2 seeps, there is far less diversity than we see elsewhere.
September 4, 2015 update: Thank you to the more than 73,000 people who took action to protect whale sharks. We are currently in direct conversations with the cruise ship industry and we hope to share updates with you soon. Watch this space!
The largest fish in the ocean is one of the most majestic, too: the whale shark. These gentle giants are also in danger.
Right now, there’s a very simple way to protect them, and you can help. Off the coast of Mexico, thousands of whale sharks gather to feed and mate every year. Unfortunately, there are two cruise ship companies whose cruises currently travel through this important area where whale sharks congregate in large numbers and swim slowly at the surface of the water.
The beauty of this area is bringing more and more visitors each year, and unfortunately, they are having some negative effects on the whale sharks. There is an easy step to be taken in protecting whale sharks in this region, and we hope you’ll take just a moment to let Carnival and Royal Caribbean Cruises know how important it is to you that they adjust their course by 7 miles to protect these magnificent animals.

Despite the potential Discovery Channel royalties, it’s not easy being at the top of the food chain. Apex predators like sharks, that occupy the top of a food chain, are typically few in number because of certain characteristics (e.g. slow growth, low reproduction, delayed maturity and high longevity). And they are greatly dependent on animals lower on the food chain, thus dependent on the environmental conditions that support these food sources.
Humans, the Earth’s reigning “apex predator,” are clearly an exception to this rule. The human population has grown exponentially, particularly along coastal communities, bringing with it a litany of impacts on our coastal ocean, including habitat loss, pollution and overfishing. Rapid coastal development in California back in 1940s-1970s, resulted in some of the worst coastal water and air quality that existed anywhere in the country.
But since the 1970’s California has significantly improved water and air quality due to strict environmental regulations on discharge and emissions. In fact, California now has some of the most conservative environmental regulations in the country when it comes to water and air quality. As a result of strict regulations on waste water discharge, the state has cleaner water now than it did in the 1970s even with three times more people living along the coast.
This guest blog comes from Sonja Fordham, she directed Ocean Conservancy’s shark conservation work from 1991 to 2009. She’s now based just up the block from Ocean Conservancy’s DC headquarters, running Shark Advocates International, a non-profit project of The Ocean Foundation. Learn more about Sonja’s work from the Shark Advocates Facebook page and website: www.sharkadvocates.org. Sonja is live-tweeting Shark Week programming; follow @SharkAdvocates for conservation policy tidbits and ideas for helping sharks of all shapes and sizes.
Shark Week has been around a bit longer than I’ve been working in shark conservation. The record-breaking cable television event has changed a lot since the early days, as has shark conservation policy and my focus for advancing it.
When Shark Week debuted in 1988, sharks – despite their inherent vulnerability to overfishing – were essentially unprotected worldwide, and “the only good shark is a dead shark” was a popular maxim. When I was hired by Ocean Conservancy (then known as the Center for Marine Conservation) in 1991, there were no federal limits on shark catches in the U.S., even though a surge in recreational shark fishing (sparked by the movie “Jaws”) followed by development of targeted commercial shark fisheries (due largely to a hike in Asian demand for shark fins) had seriously depleted several Atlantic coastal species. Even finning – the wasteful practice of slicing off a shark’s fin and discarding the body at sea – was legal.
We’ve come along way since then. By 1993, we had a U.S. finning ban and fishing limits for 39 species of Atlantic and Gulf of Mexico sharks. In 1997, take of several of those species – including great whites – was completely prohibited, following similar protections for white sharks off California that were secured in 1994. By 1999, the world had taken notice of the sharks’ plight and adopted an International Plan of Action to help guide conservation efforts on a global scale. In 2000, U.S. east coast landings of spiny dogfish sharks, which had reached nearly 60 million pounds in 1996, were cut dramatically to science-based levels. In 2002, basking and whale sharks became the first shark species to be listed under the Convention on International Trade in Endangered Species (CITES).
