SF State Launches New Floating Sentinel

Two banana-yellow buoys anchored along the Tiburon shore will be San Francisco Bay’s sentinels against shifts in water chemistry due to climate change. Known as the Bay Ocean Buoy (BOB) and the Marine Acidification Research Inquiry (MARI), the permanent moorings will provide long-term monitoring of acidity and carbon dioxide levels—key indicators of how the changing ocean will impact Bay chemistry. “It’s taken over three years of perseverance and partnership building to get these instruments into the water, but now we’ll be able to reveal how ocean acidification may be influencing SF Bay now and in the future,” says Karina Nielsen, a San Francisco State Professor of Biology and Director of the Estuary and Ocean Science Center, where the one of...

Photo Essay: Sailing, A Dying Sport or Character Builder?

Around the Bay, people who love to sail are sharing the sport with young people. Tucked into marinas and coves, and working out of portable classrooms and small offices, yacht club volunteers and nonprofit staff are working hard to get youth out on the bay in sailboats. They don’t expect to make sailors out of the kids but they do believe that getting a kid on the water, even for a few hours, has value. They know that being on a boat pushed through the water by wind teaches science and math; builds camaraderie, confidence, and teamwork; inspires environmental stewardship; and encourages the habit of saying “yes” to life. “I enjoy sailing because it’s a sport that challenges you mentally...

North Richmond Transitions

Today’s North Richmond shoreline looks much different from its historic blend of baylands, mudflats, and wet meadows. A lot of the land has been filled, or else fragmented by transit and industry. The region’s three creeks — the Rheem, the San Pablo, and the Wildcat  are mostly behind levees for flood control (the San Pablo and Wildcat Creek levees were raised in late 2017). The shoreline, and the 500 meters inland where the optimal marsh-upland transition zone could exist is bounded on one end by Chevron’s Richmond Refinery and by an Amazon distribution center and other new, massive warehouses at the other end. The middle of this zone is cut, not by long tidal plains or gentle sloping uplands, but...

Two Urban Estuaries Soften Shorelines

For two cold clear days in February, scientists, engineers, and other specialists from all three North American coasts gathered at the Oakland Airport Hilton, in what a local speaker called “the least interesting part of Oakland,” for the second national Living Shorelines Technology Transfer Workshop. The event, co-sponsored by Restore America’s Estuaries, the California Coastal Conservancy, and Save the Bay, featured talks and interactive sessions on this emerging approach to coastal protection that went well beyond technology. Referred to by some practitioners as “soft shorelines” or “green shorelines,” living shorelines projects deploy a range of environmentally friendly alternatives to armoring shores against rising seas and stronger storm surges, along a gray-to-green continuum. As speakers described challenges encountered and progress made...

Overdue Levee Almost Shovel Ready

After more than a decade of study and planning, the first part of a critical flood protection and environmental project is creeping towards construction near the town of Alviso. The South Bay Shoreline Project will eventually include over four miles of levee, 2,900 acres of restored tidal wetlands, and upgrades to the iconic Bay Trail. While the US Army Corps of Engineers waits on financing, other partners are focused on getting ducks in a row, such as coordinating access with adjacent property owners and communicating with the local community. “It’s to the community’s benefit to get flood protection, but outreach cuts down on complaints,” says the Water District’s Rechelle Blank.

Not the Last Word on Buckler

In January, the Bay Conservation and Development Commission and the San Francisco Bay Regional Water Quality Control Board appealed December decisions by a Solano Superior Court Judge concerning Point Buckler and its owner John Sweeney. The decisions voided $3.6 million in fines and cleanup and restoration requirements that the two agencies had imposed on Sweeney for dumping and excavation in Suisun Bay, and draining tidal wetland, without authorization. “If this decision sets precedent, we’re in real trouble,” says Erica Maharg of San Francisco Baykeeper. “It would mean that our agencies don’t have the authority to protect these ecosystems.”

The Art of Environmental Restoration

Cold water, essential for the life cycle of Chinook salmon, is all too often in short supply along the Sacramento River. A primary cause: California’s massive water conveyance system, using reservoirs, dams, and hydroelectric plants to divert water and deliver power to farms and cities. “When we started releasing water in spring, we let cold water out too early. None was left by fall, when salmon really needed it,” says USBR hydraulic engineer Tracy Vermeyen. Two clever innovations have been implemented to conserve cold water into the autumn. First: A 300 foot tall, 250 foot wide “adjustable straw” possessing a series of intake gates enables power plant operators to draw water from behind the dam at three different depths. Second:...

Scrutinizing the Margins

Bay margins are often mucky, fertile, out-of-the-way places. In the last decade, however, the edges of the San Francisco Bay have caught the attention of San Francisco Estuary Institute scientists as unexpected sources of pollution--and, potentially, of solutions. “The idea that you could make a big difference by just cleaning up the margins is attractive because it scales down the problem quite a bit,” says Phil Trowbridge of the Regional Monitoring Program. Historically, scientists considered the Bay akin to a massive bathtub where water pours in, mixes up, and bathes all its contents equally. A 2010 study made the surprising discovery that small fish living in the margins had higher concentrations of PCBs than larger, open water fish. While challenges...

Locals Trade Vines for Resilient Rivers

In 2002, when stretches of the Napa River running through Rutherford area vineyards breached levees and flooded yet again, Michael Honig did something remarkable: rather than call the authorities to complain, his neighbors and he banded together to restore their riverbanks. “It had became a kind of competition,” Honig says.

Hopeful Outlook for Pacific Herring

Radar Envy

Near the end of 2012, the US Army Corps of Engineers released 28,000 acre-feet of water from Lake Mendocino. Then followed 14 of the driest months on record. The key to managing the drought and deluge cycle of California lies in a better understanding of atmospheric rivers, intense winter storms that transport water from the tropics to the West Coast. Over the last decade California has pumped more than $40 million into the statewide network that tracks these rivers, giving lead times of up to a week.

Moving West for the Greater Good

The San Francisco Estuary Partnership is optimistic that a move to the Bay Area Metro Center will offer new opportunities for collaboration with other regional agencies sharing the same roof.
