The California Ocean Protection Council and the California Natural Resources Agency have updated statewide guidance on sea-level rise to reflect new advances in ice loss science. Their new report, “Rising Seas in California: An Update on Sea-Level Rise Science,” notes that satellite data of West Antarctica show an increased loss of grounded land ice and Read More
This is the second part of a two-part series about the recent unusual mortality events of California sea lion (Zalophus californianus) pups. The first article investigated the reasons why thousands of emaciated pups have been stranded on California beaches. This article highlights the work of nonprofit organizations dedicated to rescuing and rehabilitating them. Rescue A Read More
On July 16, 2016, the Marine Mammal Center released four rehabilitated California sea lions in Morro Bay.

When the La Esplanade Apartments were built in the early 1970s, on a bluff overlooking the Pacific Ocean in the Bay Area coastal community of Pacifica, lucky residents were treated to an incredible ocean view out their back windows and balconies. Before them lay a couple of hundred feet of ice plant-covered ground before the Read More
On a Sunday morning in March 2013, I spotted three dead California sea lion pups and two dying pups on the beach just south-east of the cliffs in Point Dume, Malibu. I called the Marine Mammal Care Center for help but they were overwhelmed and could not assist the pups. Two years later in April Read More
El Niño finally arrived in the San Francisco Bay Area this winter. The local hills turned green, and reservoirs and creeks were filled from the abundant rainfall. But the accompanying ocean storm surges off the Pacific Ocean pounded the coast, causing the erosion Read More
Two independent long-term time series show four decades of declines within fish populations in the California Current, with no sign of reversal. The data set from the California Cooperative Oceanic Fisheries (CalCOFI) and the data set from the power plant cooling water intakes (PPI) were taken from five sites along the California Coastline. Both sets Read More
