The Point Reyes peninsula is surrounded on three sides by the Pacific Ocean which dramatically affects the daily and seasonal climates, and numerous resident and migratory marine species. Besides the El Niño / Southern Oscillation (ENSO) and Pacific Decadal Oscillation, the most significant oceanic impact on the peninsula is the seasonal upwelling phenomena. Upwelling occurs when nutrient-rich colder waters rise from deeper levels to replace the relatively warm surface waters, and as a result creates summer coastal fog. The transport and cycling of these nutrients to the surface are responsible for the high productivity around Point Reyes that supports a large diversity of species throughout the food chain and into the ecosystem.
This high level of biodiversity is at risk, however, from a variety of causes. From the affects of climate change to changing the chemistry and acidity of ocean waters to using the oceans as a dumping grounds for toxic, radioactive, and plastic wastes to overfishing, humans have dramatically altered ocean ecosystems. Read Altered Oceans, a Pulitzer Prize winning five-part series on the crisis in the seas. This series was written by Kenneth R. Weiss and Usha Lee McFarling and published by the Los Angeles Times in the summer of 2006.
While humans have the capacity to destroy much of the life found in the ocean, we also have the ability to save and restore ocean ecosystems. Visit thankyouocean.org to find out what you can do to help protect this vital resource. You can also read 50 Ways to Save the Ocean by David Helvarg (2006, Inner Ocean Publishing). Some of Helvarg's recommendations were incorporated into a series of Ocean Updates for World Ocean Day 2008, as well as by Sea Turtle Restoration Project on their 50 Ways to Help Save the Ocean page.
With bottles, cans, abandoned or lost fishing gear and other marine debris washing up on our shores each year, the University of Georgia and NOAA have teamed up to create an innovative cell phone reporting mechanism to combat the marine debris problem. This high-tech tool, or app, tracks where marine debris is accumulating and gives anyone with a "smart phone" an opportunity to be a part of the solution.
To learn more about ocean conservation topics you can tune into KWMR once a month for Ocean Currents, a radio program hosted by Cordell Bank National Marine Sanctuary staff that focuses on ocean topics locally and globally. Tune in the first Monday of every month at 1:00 PM on KWMR at 90.5 FM Point Reyes Station, 89.3 Bolinas, or live on the web at www.kwmr.org. You can also subscribe to the Ocean Currents podcast or hear archived shows by going to Cordell Bank's Ocean Currents Podcast page. Learn about rockfish, artificial reefs, humpback whale research, sustainable seafood, history of the Farallon Islands, the Marine Life Protection Act, plastic in the ocean, bioluminescence and more!

Did You Know?
Northern elephant seals (Mirounga angustirostris) began breeding at Point Reyes in 1981 after being absent for over 150 years. The population breeds at terrestrial haul out sites at Point Reyes Headland, one of only eleven mainland breeding areas for northern elephant seals in the world. More...
