When Facing Ocean Acidification it’s Location, Location, Location

For us landlubbers, it is obvious that place matters.  My home town in central California is a pretty different place than say, Washington DC, where I often travel to advocate on behalf of ocean conservation.  The weather is different, the food is different, and the culture – not to mention the politics – is certainly different.

It turns out that place really matters in the ocean too, especially as it relates to ocean acidification.  Never heard of ocean acidification?  Check out some of my earlier posts to learn more about the basics.  But what we learned from scientists last week is that the chemical characteristics of the ocean vary greatly from place to place, and as a result some areas may be especially sensitive to increases in carbon dioxide and other drivers of acidification.  A team of oceanographers led by Dr. Aleck Wang sampled seawater from Texas to New Hampshire and measured the total amount of carbon in the water as well as what scientists call “alkalinity.” The ratio of alkalinity to total carbon is a measure of the buffering capacity of the ocean, or in layman’s terms, the ocean’s ability to resist acidification. What the scientists found was that the Gulf of Maine is much more susceptible to acidification than the Gulf of Mexico or the southeastern coast.  Continue reading »

Fishing for Data: How a Day on the Water is Aiding Scientific Success

When volunteer anglers aboard the Huli Cat bait a hook trying to catch a rockfish, they’re not just fishing – they’re helping researchers learn more about California’s underwater parks. Recreational fishermen, SCUBA divers, PhD scientists and graduate students are working together to study California’s marine protected areas (MPAs), and results from their studies are being presented this week in Monterey.

Five years ago, California completed its network of MPAs on California’s central coast. This anniversary is being marked with the State of the California Central Coast Symposium, which brings together scientists, resource managers, policy makers, fishermen and conservationists to learn about new findings from dozens of monitoring efforts and discuss perspectives on MPA management.

Early results suggest that the reserves are on track, allowing fish like cabezon and lingcod to grow larger and more abundant inside MPAs, with habitats that are more biologically productive. This, along with steadily increasing revenues for fishermen, is good news for the Central Coast MPAs. However, researchers stress that these first five years of study are meant to create a baseline: a barometer of ecological health against which future MPA performance can be measured. So, how exactly are these reserves being studied? It turns out that monitoring is both sophisticated and wonderfully simple.

One great example of this is Dr. Rick Starr’s California Collaborative Fisheries Research Program (CCFRP), which uses local charter fishing boats to monitor four MPAs. Volunteer anglers from the local fishing community team up with graduate students by fishing for rockfish while painstakingly recording the weight and species of every fish they catch and release. They’ve caught over 40,000 fish in the past five years, and have noted how great the fishing is by the relative abundance of some species inside the MPAs.

Another monitoring project is Reef Check, which teams PhD researchers up with citizen scientists who strap on SCUBA gear to survey shallow and deep rocky habitats, kelp forests, rocky shores, estuaries, beaches and other key ecosystems along the central coast. They monitor ecologically and economically important species of fishes and invertebrates, and human activities including fishing and recreational use.

One consistent theme in these studies is that citizens of the coast are vital to the success of the marine reserves. Volunteers have been involved in scores of monitoring and outreach projects. Citizen science efforts like MPA Watch have trained hundreds of volunteers to monitor beach and coastal use in and around protected areas like Natural Bridges and Año Nuevo.

Save Our Shores’ Dockwalker program is another great example of an organization working with coastal citizens to help the MPAs. The Dockwalker program shares information with boaters and fishermen about MPAs, and conducts ocean protection workshops in local schools. In turn, schools are making visits to the underwater parks part of their outdoor education program, because in addition to enabling kids to watch wildlife in nature, many now feature full-color educational interpretive displays and instructor programs.

From school children looking to learn more about marine life to fishermen looking to catch more fish, California’s new marine protected areas are an investment in the future. By studying them with the assistance of citizen volunteers, we are learning about the full range of benefits they provide to marine ecosystems, and becoming better stewards of these places in the process.

Protecting Fish is Good for Business: How a Florida Study Bodes Well for California

According to NOAA’s new study on the Tortugas Ecological Reserve, located in the Florida Keys National Marine Sanctuary, protecting fish is in everyone’s best interest.

The 151-square nautical mile reserve was established in 2001 to protect overfished species. According to Science Daily, the protections have boosted fish populations, with bigger and more abundant yellowtail, mutton snapper and black and red grouper appearing within the reserve. These results are consistent with findings marine reserves around the world, which find again and again that the size, abundance and diversity of marine life increase inside fully protected marine reserves.

The biggest news for resource managers, however, is the socioeconomic implications. The new study finds that commercial catches of reef fish in the region have increased along with the fish population increases, and that neither commercial nor recreational fishermen have experienced financial loss as a result of the reserve.

The first month of the year is perhaps the best time to experience California’s ocean at its finest – which is why the 5th Annual Underwater Parks Day on Saturday, January 19th is a great reason to hit the coast and enjoy one of over 100 new underwater parks, which protect entire ecosystems at iconic coastal areas such as La Jolla, Point Reyes, and Point Lobos. To find an event near you, we’ve included a full schedule of events by region linked below.

It’s already been a busy month for California’s new underwater parks. Grey whales are traveling south along the coast to lagoons in Baja, California where they will give birth to calves. Some preemies and their mothers are already showing up off the coast of Los Angeles and San Diego, delighting whale watchers.

Further north, in Piedras Blancas and Año Nuevo State Park’s marine protected areas, male elephant seals are engaging in their spectacular, violent mating rituals, while females are giving birth to a new generation of pups. Continue reading »


Celebrating a Big Week for California Coasts

California coasts—and all of the wildlife and people who enjoy them—are having “the best week ever.”

North Coast protected areas go into effect

Earlier this week, we celebrated the official completion of California’s statewide network of underwater parks—the first in the nation—as the North Coast marine protected areas went into effect.

As our own Jennifer Savage wrote, earlier in the week, this completed network marks the culmination of many years’ work, and protected areas will go a long way toward ensuring that ocean wildlife can thrive:

From the Oregon border to the Mexican border, the fish, birds, mammals and plants that depend on the dynamic habitats of the California coast now have a series of reserves and conservation areas that will allow their populations to recover where needed and protect them from depletion in the future. Not only is this good for the sea creatures, but a thriving ocean benefits all of California, from the fishermen whose livelihoods depend on healthy fisheries to all aspects of the state’s tourism-dependent economy …

Slide Show: Exploring California’s New Underwater Parks

Posted On December 20, 2012 by

Dive in above for a closer look at California’s recently completed statewide network of underwater parks, some of the species they protect, and the people that are enjoying them.

Over 120 new parks now dot the California coast, protecting habitat-rich areas and iconic locations like Point Reyes, La Jolla, Point Lobos, and Fitzgerald Marine Reserve. These parks have the potential to restore abundance to depleted areas, and ensure a healthy ocean full of fish for the future.

Read our in-depth look at the nation’s first statewide network of underwater parks here.


California Celebrates 19 New Underwater Parks, Completes First Statewide Network in Nation

Each day, many of us do small things we hope will benefit the ocean. We bring our own coffee mug. We pack our groceries into cloth bags. We wash our cloth napkins in cold water and buy our detergent in bulk. We bring our own to-go containers to the sushi spot – and we always order our fish based on what’s sustainable.

But the ocean is in trouble, and needs more than individual efforts for deepened protection. In California, efforts to restore the state’s depleted fish populations resulted in the Marine Life Protection Act, which passed the legislature back in 1999.

Today, the California network – the first in our nation – finally becomes complete: The North Coast marine protected areas go into effect. From the Oregon border to the Mexican border, the fish, birds, mammals and plants that depend on the dynamic habitats of the California coast now have a series of reserves and conservation areas that will allow their populations to recover where needed and protect them from depletion in the future. Not only is this good for the sea creatures, but a thriving ocean benefits all of California, from the fishermen whose livelihoods depend on healthy fisheries to all aspects of the state’s tourism-dependent economy – people come to California to see the ocean, be awed by the magnificence of migrating whales, explore the glowing tide pools along our beaches, delight in barbecuing lingcod, fresh-caught or bought off the docks.
