Will radiation from Fukushima harm distant seafood consumers?

I’ve been receiving questions from concerned friends and family about how radiation from the Fukushima Dai-ichi nuclear power plant is affecting the marine environment and human seafood consumption. As ocean lovers, I’m sure you’re equally concerned. After reading different scientific articles and speaking with experts, I found that there are local impacts from radiation to humans and marine life around Fukushima – but impacts from radiation on the rest of the Pacific Ocean are not expected to be harmful to human consumers and marine animals.

5 Reasons to Celebrate California’s MPAs

Posted On December 11, 2013 by

They grow up so fast! I can’t believe it’s already been a year since California established the first statewide network of marine protected areas (MPAs). I remember when these special places were just a glimmer in our collective eye—when scientists, fishermen, agencies and conservationists were still flirting with the idea of protecting coastal waters in a string of underwater parks from Mexico to the Oregon border.

And now here we are, one year later, celebrating a first birthday on December 19 and 124 fun reasons to get outside, get in the water and raise a glass to California’s future. Looking forward and looking back, here are some of my favorite reasons to celebrate:

Marine Protected Areas Around the Globe: Looking Back, Moving Forward and Sharing Recipes

Posted On November 4, 2013 by

I’ve recently returned from the 3rd International Marine Protected Areas Congress in Marseille, France. The experience of meeting so many different kinds of people, all equally passionate about the ocean, has inspired me. It’s planted a desire to follow up and exchange marine protected area stories—and recipes—from California with those from around the world.

To that end, please join me this Wednesday, Nov. 6, from 2-3 p.m. PST for a lively and fun Twitter Party, where you can share the global MPA stories you heard at IMPAC3. Missed the Congress? No problem—we’d like to hear your thoughts about MPAs, even if you weren’t there. Follow @ThePacificOcean, @OurOcean and @HealTheBay, or #MPAsWork to join the conversation (and win prizes!) this Wednesday.

Sarah Sikich (Heal the Bay) and I (Ocean Conservancy) will be leading the party, but it’s largely driven by participants. Topics will include: our evolving need to understand MPAs over the last decade, Sylvia Earle’s 50 Hope Spots, the value of urban MPAs, the issue of large MPAs and quantity versus quality, our shared MPA lessons from around the world and, of course, where we go from here.

California Delegation Shines Spotlight on Marine Protected Areas at International Conference

If you’ve been lucky enough to go for a dive, surf or kayak at the Channel Islands, it’s hard not to be captivated by the cathedral kelp forests, large fish cruising the reef and clean waves breaking under your surfboard. These islands, along with special places throughout the entire California coast, enjoy protections that allow the marine wildlife inside to thrive.

Like underwater parks, the marine protected areas (MPAs for short) here act as safe havens for marine life and giant kelp forests that call southern California’s coastline home. And the good news is that globally, MPAs are on the rise. There are over 6,000 MPAs worldwide, yet less than 2 percent of our ocean is protected.

Next week, ocean scientists, policymakers, leaders and conservation professionals will be convening in France to share ideas about how to foster MPA effectiveness around the world at the 2013 International Marine Protected Areas Congress. And California’s story will be among those in the fold.

Noted Scientists Debate Value of Large-Scale MPAs

Two ocean experts went head to head this week over the value and environmental impact of creating large no-take zones – such as Australia’s recently designated 500,000-km2 no-take area in the Coral Sea. They took part in an online debate on Tuesday Oct. 8, which was sponsored by OpenChannels.org, MPA News, and the EBM Tools Network.

In one corner was Callum Roberts, a professor of marine conservation biology at York University (UK), who argued that the total environmental impact of large no-take areas is positive.

In the other corner was Ray Hilborn, a professor in the School of Aquatic and Fishery Sciences at the University of Washington, who argued that the total environmental impact of large no-take areas may be negative due to the need to make up food production in another way, either at sea or on land.

9 Great California Coastal Birding Sites

Posted On September 16, 2013 by

This article originally appeared at Audubonmagazine.org.

Whether novice or expert, birdwatchers in California delight in the avian abundance along the state’s coast. California also boasts the nation’s only statewide network of marine protected areas, providing not only gorgeous places to seek out a stunning diversity of birds but insurance that their most important breeding and feeding grounds have extra protection.

Below is a list of the top bird-watching spots at these “ocean parks,” plus highlights. Additionally, there is information about visiting, plus a link to where you can learn more.

1. Point St. George Reef Offshore State Marine Conservation Area

Originally inhabited by the Tolowa Dee-ni’, California’s northernmost coast boasts some of the most dramatic scenery in the state and is dotted with Audubon-designated Important Bird Areas. A wide range of bird species live and migrate around nearby Lake Earl, and the profusion continues at sea, where exposed rocks and underwater ledges make up the St. George Reef. Reaching the protected area requires a boat, but visitors can experience similar conditions from the safety of the shoreline just south of the point, where Castle Rock National Wildlife Refuge sits.

The refuge is a modest 14 acres, yet it supports several hundred thousand seabirds each year. Take a spotting scope to Pebble Drive from February to mid-April to catch the dawn fly-off of Aleutian cackling geese. Observe one of the largest breeding populations—100,000—of common murres making their nests along the island’s cliffs. Castle Rock is also home to three species of cormorants, pigeon guillemots, Cassin’s and rhinoceros auklets, Leach’s and fork-tailed storm-petrels, and tufted puffins.

A Season of Hope for Progress on Ocean Acidification

Fall is upon us, and with it comes a new season, new beginnings and new opportunities. The saying “hope springs eternal” evokes an entirely different season, but this autumn I’m feeling particularly excited and optimistic—and it has nothing to do with football. Great things are happening on ocean acidification, and this is an issue that I’m always happy to have something good to talk about.

Just last week, California announced a groundbreaking science panel comprised of world-class scientists from California, Washington, Oregon and British Columbia. Long a leader on environmental issues, California is taking a page from Washington state’s excellent playbook in tackling ocean acidification at the state and local level.

State efforts to address this issue are essential. Ocean acidification is a global ocean health problem, caused by our increasing carbon emissions from factories, cars and power plants being absorbed by the ocean—but its impacts are local. Ocean acidification is putting American jobs and livelihoods at risk.
