NOAA’s Ocean Acidification Program (OAP) seeks to better prepare society to respond to changing ocean conditions by understanding the processes of ocean acidification through interdisciplinary partnerships both nationally and internationally.

A new study offers a science-based method to assess protection levels in marine protected areas (MPAs) when information on regulated human activities is limited.

Santa Cruz citizens and neighbors are summoning new energy and vision to “Save West Cliff.” The iconic 2.7-mile promenade that presents stunning, unimpeded views of the ocean has meant so much to so many for so long. With climate change now accelerating its challenges, citizens and the city now also step up their work and advocacy. Next up: a Feb. 13 “community conversation” about West Cliff Drive.

By 2100, sea levels are expected to rise by four to seven feet along the stretch of Bay from Fisherman’s Wharf to Heron’s Head Park. If left unchecked, the rising waves will pollute drinking water with salt and other contaminants, flood buildings, homes, and infrastructure, and inundate roads, parks, and open space.

Oceanside has approved the next phase of its sand restoration and retention project at a cost of $2.6 million, though city officials have downplayed the possibility of an earlier proposal to build beachfront ledges.

The usual blue waters of the Pacific Ocean off the coast of San Diego are looking quite different — at least for a while. Bright fuchsia-colored waves were seen crashing along the shore in the past week, and researchers have revealed just what's causing the sudden and dramatic color change.

Good news for fans of non-motorized transportation: The last stretch of trail needed to connect Eureka and Arcata is getting closer to realization.

Hundreds of visitors to Montecito's Butterfly beach on January 22, 2023, a favorite seascape of Royals and Movie Stars, were confused, then awed, to see rocks strewn all over the walkways, sidewalks, street and sand, further altering a landscape already dramatically changed in recent weeks due to the atmospheric river/storm surge.

DEL MAR — After nearly seven years of confusion and controversy over the viability of short-term rentals in Del Mar, city officials have started crafting a new ordinance to regulate their operation while also extending a ban on new rentals for another two years.

Total US economic losses from the recent flooding in California will be between $5 billion and $7 billion, according to an estimate by catastrophe risk modeling firm Moody’s RMS. Insured losses are estimated to be between half a billion dollars and $1.5 billion, including losses to the National Flood Insurance Program and the private flood market.

Uncaptured runoff flowing to the sea flushes pollutants out of rivers and bays

SAN DIEGO— The Port of San Diego is releasing the results of its first study on carbon sequestration and storage in eelgrass beds.

For residents of Stinson Beach, the sight of ocean waves running up their streets, carving away tons of sand, flooding homes and even washing a house or two into the sea every decade or two has been an accepted tradeoff for a beachside lifestyle.

BIG SUR — The engineers and laborers who constructed California State Route 1 from Carmel to San Luis Obispo County beginning in the 1920s knew the road was fraught with peril. But they did it anyway. Coastal communities in the area needed better access to health care and other resources.

Vital Alameda Point wetlands are slated for costly and unnecessary destruction without scientific support.

The University of California will award $100M in climate action grants this year to help communities across the state meet the challenges of climate change.

The San Diego sewage spill was the largest of four reported in San Diego County on Monday that led to the county Department of Environmental Health to close beaches and bays to water contact BY

Four dams on the Klamath River in northern California and southern Oregon will be removed this summer. For stakeholders, it’s been a long, strange trip to reach this point in the dams’ history.

I wasn’t sure it was possible, but we actually did go from drought to flood in a week’s time; and the city’s only reservoir, Loch Lomond, is now 100% full and overflowing.

Reverend Daniel Paul arrived at First Christian Church of Huntsville in mid-November, after serving for 24 years at Christian Church of Pacific Grove, California. That church was only half a block from Monterey Bay and Stanford University’s Marine Biology Lab.

Looking to fill in a missing piece of the climate change puzzle, the work of a former researcher at UC San Diego’s Scripps Institution of Oceanography in La Jolla that studied carbon capture by mangroves in far parts of the world is making its way to San Diego-area wetlands.

With a break in the storms, crews are cleaning up the mess left behind following the recent big surf and heavy rains that battered the region in the past week.

A series of atmospheric rivers has caused storm damage to infrastructure throughout Santa Cruz County. On Thursday, the wharf in Capitola was broken in half by a powerful storm surge.

David Schmalz here, thinking about sand. That’s because, with the recent storms, the beaches along southern Monterey Bay will be seeing more of it. Monterey County officials cut a canal in the Salinas River in December as a preventative measure for flooding, allowing the river to flow freely into the bay, south of the Monterey Submarine Canyon.

MONTEREY — On a recent Saturday morning, scuba divers Keith Rootsaert and Dan Schwartz splashed into the ocean just east of Old Fisherman’s Wharf, the chilly water swallowing the sounds of Monterey Bay as they descended. Upon reaching the seabed, each diver grabbed a spiky purple sea urchin, braced it against a rock and pulverized its center with a welding hammer — all in the name of saving giant kelp.
