Soquel Canyon State Marine Conservation Area

Soquel Canyon is the northernmost branch of the Monterey Canyon, a massive underwater marine canyon that extends nearly 100 miles from shore and is almost one mile deep in some places, with the area covered by Soquel Canyon SMCA reaching depths greater than 2,100 feet. Soquel Canyon SMCA encompasses sandy seafloor and deep canyon ecosystems that are highly productive due to regular upwelling events and the California Current.

Strong upwelling caused by consistent northwest winds brings deep, cold, nutrient-rich water to the surface while the California Current brings similar waters down from the northern latitudes. The combination of nutrients supports huge numbers of small creatures called phytoplankton and zooplankton, which in turn support the many species of fish, deep ocean crustaceans, and marine mammals found in the SMCA. Swarms of baitfish, like sardines and anchovies, may appear in Monterey Bay to feast on the plankton, and with their presence Monterey Bay can explode into a feeding frenzy. Massive humpback and blue whales are easily spotted from shore or by boat, diving and resurfacing, making a meal of the tiny animals.

Smaller marine mammals like dolphins, porpoises, seals, and sea lions maneuver amongst the giant whales and claim even more of the baitfish for their own. In the middle of the chaos, gulls, murres, pelicans, shearwaters, and auklets dive, swoop and swim in the water, grabbing fish near the surface. Thousands of feet below, the depths of the canyon are home to rarely seen deep sea animals such as bluntnose sixgill sharks, elusive rockfish, and predatory tunicates.

For centuries, Native American Tribes in California have relied on marine and coastal resources. Many Native American Tribes in California continue to regularly harvest marine resources within their ancestral territories and maintain relationships with the coast for ongoing customary uses. Before the Spanish arrived, much of the territory from San Francisco to Monterey belonged to the Ohlone people. The Ohlone traditionally subsisted on the abundant marine and terrestrial resources in Monterey, collecting abalone, urchins, limpets, and seaweeds in rocky intertidal areas and steelhead and salmon from the rivers and the coast.

During the 18th century, tribal communities were displaced by the Spanish, who established missions. In Monterey, the first presidio was built in 1770. Soquel Canyon and the greater Monterey Canyon were used during the rapid expansion of the whaling and fishing industries of Monterey Bay in the middle to late 19th century. Chinese immigrants launched the fishing industry and turned Monterey into a thriving fishing port, with commercial fisheries that harvested abalone, rockfish, flatfish, sardines, and squid. Between 1915 and 1950, estimates suggest that 235,000 tons of sardine were fished from the bay every year, until the fishery collapsed in the 1950s. Similar collapses of other fish stocks from overfishing resulted in more stringent regulations and the implementation of MPAs.

Today, Monterey Bay supports a thriving fishing industry and is a model of balanced management between conservation, recreation, and commercial uses. Soquel Canyon SMCA is one important part of a greater conservation network in Monterey Bay including many state MPAs as well as the Monterey Bay National Marine Sanctuary. The MPAs and Sanctuary not only provide protection for marine ecosystems, but also draw tourists, support fisheries, and help to conserve California’s marine resources for future generations.

Soquel Canyon SMCA is located offshore, within Monterey Bay, and is only accessible by boat. For those with access to a boat, Soquel Canyon SMCA provides excellent fishing for pelagic finfishes, such as swordfish, tuna, and bonito, but take of non-pelagic finfish is prohibited.

Monterey Bay and the canyon areas also offer some of the best whale watching in the world. Humpback, gray, and blue whales are commonly seen and orcas are occasionally observed. The harbors at Santa Cruz and Moss Landing are roughly equal distance from Soquel Canyon SMCA and have public boat launch ramps.
