An enormous, black raft was bobbing among the many waves at Loon Level on Tuesday, headed for the shoreline halfway between Summerland and Carpinteria. “I believed it was a kelp mattress floating towards the seaside,” stated Jon Vaccaro, who watched as the large mass washed up, breaking into thick gobs of smelly tar because the waves dumped it alongside the seaside.
As soon as the petroleum mess had come ashore, Vaccaro stated he thought of going for a swim by way of a transparent spot, however the ocean was left with a foamy brown shade flecked with bits of goo that caught to his legs. As a substitute, he took photographs of what he estimated to be a football-field’s size of gooey tar, sending them to the Indy and questioning if the “cork” talked about in Callie Fausey’s story about re-abandoning oil wells off Summerland is likely to be accountable.
Offshore oil has a fractured historical past in Santa Barbara County, relationship from Summerland’s growth and bust years circa 1897-1939, by way of to 2015’s Refugio Oil Spill, which precipitated Venoco’s chapter after an important pipeline break up open. The oil giants left holding the bag are preventing to maintain pulling petroleum out of the depths, with possession of the ruptured pipeline above Refugio Seaside to be litigated earlier than the County Board of Supervisors this Tuesday. However persistent seeps of crude have floated up from cracks beneath the waves since earlier than Chumash occasions.
At Butterfly Seaside in early August, the waves left behind a mushy, sticky crude on a stretch of sand that’s reputed to have little or no tar. Nobody with the parks or harbor knew the place it may have come from, and everybody stated to contact Heal the Ocean.
The nonprofit’s area researcher Harry Rabin has been monitoring tar balls ever since he noticed brown waves of oily foam at Miramar Seaside in 2016 and used a drone to observe it two miles east to Summerland. There, on the web site of the world’s first offshore oil wells, seven wells quietly oozing crude underneath the sands and waves have been re-abandoned, or closed with concrete and metal, since 2018. The final two — Treadwell #1 and #5 — had been completed in mid-August, a couple of weeks earlier than Vaccaro’s encounter. Rabin wasn’t stunned to study of the massive burp of tar however doesn’t imagine it’s essentially associated to the properly capping.
Working with the State Lands Fee, Heal the Ocean has been placing the $2 million a yr offered by Senate Invoice 44, authored by Santa Barbara’s former state senator, Hannah-Beth Jackson, to shut the outdated wells that at the moment are leaking. Subsequent seepage from different fractures wasn’t surprising, and the nonprofit is working with Ira Leifer’s Bubbleology Analysis Worldwide to check the leaky wells and plot the reservoirs of oil that stay under.
Leifer said that the Treadwell Wharf in Summerland — which went 1,200 toes out over the water and had about 19 wells on it in 1900 — tapped a fracture zone referred to as the Ortega fault. He stated he wouldn’t be stunned if the fault had shifted and the “dinosaur goop” had migrated upward, or that the crude had discovered a brand new path after the wells had been capped. Pressures had elevated as properly after the heavy waves and document rainfall this winter recharged the aquifers extending underneath the ocean.
Rabin added that the tar he’d seen alongside the seaside not launched the rainbow sheen that marked a recent glob of oil. With the rotation of the gyre within the Santa Barbara Channel, it’s potential the tar may have floated from Coal Oil Level close to UC Santa Barbara, or that it’s the product of a pure seep someplace out within the channel.
“Some fraction of the goop circles the gyre, and when it returns encrusted with barnacles, you understand it’s been on the market for a while,” Leifer stated.

Heal the Ocean’s research with Leifer’s firm will embody working with the U.S. Geological Survey to “fingerprint” the Summerland properly seeps and the tar washing ashore to get a greater thought of the place they’re coming from. This distinctive science would take aside the chemical composition of the assorted offshore oil sources and would require some severe analytical horsepower, stated David Valentine, a geoscientist and underwater oil knowledgeable at UCSB who’d additionally been speaking with Heal the Ocean.
“I’ve checked out some oils from Summerland earlier than, and the sphere there has very completely different oils from seeps I’ve checked out within the space. So, differentiating the oil area needs to be easy — that means you might inform if a tar ball is from Summerland versus Goleta or Level Conception,” Valentine stated. If materials from wells had been to be in contrast, there might be refined variations of their chemical composition, he surmised, however there was additionally a possible they might be indistinguishable.
“This might be a non-trivial process,” Valentine stated. “That’s science code for actually troublesome with a average likelihood of failure.”
On the seashores, the tar will get on toes, into hair, underneath bathing fits, and coats surf and boogie boards. “What I appreciated about Loon Level is that it’s often a lot cleaner,” stated Vaccaro. “I perceive that we wish to cap the outdated wells, however these cracks within the earth are unlucky.” As for Loon Level, he hasn’t been again.
