Mass-starvation events have hit a spectrum of other West Coast marine wildlife, mostly due to the collapse of food chains brought on by warmer ocean water.
In any other year, the large bins of Dungeness crab that are loaded dockside in this busy fishing village and rolled out by truck to be sold and served during the holidays would seem like no big deal.
But after an unprecedented delay in the 2015-16 commercial season forced local crabbers to leave their boats tied up through winter and on into spring, the tons of meaty crustaceans landed in port this month have been a welcome sign of normalcy restored, if only for a moment.
For here on the edge of the Pacific, where commercial fishing remains a way of life, once reliable ocean rhythms have been seriously unsettled of late, confounding those who depend on predictable, seasonal cycles and highlighting future uncertainties.
Even the current Dungeness season lurched off to a bumpy start, with the fishery opening piecemeal and mostly behind schedule, a symptom of widespread marine anomalies that have prevailed for the past three years, threatening everything from seabirds and sea lions to treasured catches such as salmon and abalone.
“The ocean is changing,” one glum crabber aboard the vessel New Horizon said while waiting to unload his catch recently at Tides Wharf. Offshore a strong storm was building and the fisherman summed up the fishing industry’s environmental troubles with hard-earned experience.
“Irregularity “is starting to look like the new normal,” he said.
Scientists and fishermen alike are unsure about the degree to which recent upheaval fits within the ocean’s normal rhythms — which are complex — or is part of some longer-term trend, perhaps linked to global climate change and its many ripple effects.
It’s likely a bit of both, given the context of the Earth’s warming, though more immediate atmospheric conditions have been the primary suspect, scientists say.
“Climate change syndrome is definitely having an impact,” said John Largier, professor of coastal oceanography at the UC Davis Bodega Marine Laboratory. “…What is very difficult to tell is how much.”
It appears that an expanse of high-temperature water along the coast of North American known as “the Warm Blob” is mostly to blame for recent disturbances affecting the coast of California, causing significant redistribution of wildlife, disruptions in the food web and large-scale mortality in a variety of animals.
