Calif., Wednesday, May 20, 2015. A broken onshore

On Tuesday, over 100,000 gallons of oil gushed
onto a nine mile stretch of California coastline.
A buried pipeline ruptured next to a culvert that
led to a Santa Barbara beach, sending oil
straight into the water. Government officials
have closed both Refugio State Beach and El
Captain State Beach until next Tuesday; its the
worst oil spill to hit the Santa Barbara
coastline since 1969, when 4.2 million gallons of
oil slicked the Pacific and helped trigger the modern environmental movement.
This isn't just any beach. In the Santa Barbara
Channel, cold water from the north meets warm
water from the south, carrying a mosaic of
unusual species. Its almost Mediterranean, and
its rare. Off California, massive forests of
kelpthe largest type of marine algaecreate
this really cool three-dimensional habitat that
harbors a lot of biodiversity, says Bob Miller,
a marine biologist at UC Santa Barbara. The
seaweed grows up to 130 feet tall and supports
more than 800 species, including infant fish and
invertebrates like crabs and snails. Bigger
marine mammals like sea lions and otters often
forage for food through the leaves. When kelp
breaks loose and washes up on shore, arthropods
and birds eat it. seagulls, terns, and cormorants
forage the beaches. About 19,000 gray whales
migrate through the channel this time of
yearsometimes as close as 100 feet from shore.
And the rocky intertidal areas harbor sea
anemones, soft corals, shrimp, muscles, crabs, and small fish.
But oil screws all of that up. Its viscous, and
depending on temperature it either oozes everywhere or sticks to everything.
The 14,000 acres of kelp sprawled around the
coast captures big gobs of oil in the canopies,
so it settles like a toxic cloud on the algal
forests. If little animals eat the oil they
either die, or get eaten by bigger animals,
spreading the toxic stuff through the food web.
John Ziegler, of Pismo Beach, Calif, part of a group of citizen
Oil that wave action pushes into the rough
terrain of the rocky intertidal zone gets trapped
in the natural nooks and small spaces. These
crannies are partially isolated, ecologically
speakingthats why tidepools are so cool. But it
also means that when damaged by oil, they can
take a much longer time to recover than other marine environments.
Bird species face some of the biggest risks.
Foraging on the beach means running into oil that
washes up on shore, which is like walking into a
tar pit. Brown pelicanswhich spent almost 50
years on the the Federal List of Endangered and
Threatened Wildlife before being removed in
2009dive into the water to hunt for fish, which
means they end up diving headfirst into an oil slick.
Hey, at least the plants and animals down on the
bottom will be OK, right? Sure! Unless an
intensely sunny daylike, you know,
Californiawarms the oil enough that it sinks.
Thats what happened after the Exxon Valdez spill
in Alaska 25 years ago. People are still digging
crude out of sediment from the ocean floor there.
Its too early to tell exactly what'll happen off
Santa Barbara. Ben Halpern, a marine conservation
researcher at UC Santa Barbara, says the most
visible short term effect will bird deaths from
eating oil-related chemicals. Its clearly a
disaster, but it will be relatively contained,
he says. There will be major impact on the local
scale, but not the regional one. He predicts
much of the oil will be cleaned up within a year
or two, although there will still be pockets of
oil that subsist for many years afterward.
Because many of these toxins directly affect
reproductive organs, Miller says to expect a
decrease in overall population over the next few generations.
On the slightly brighter (albeit ironic) side, UC
Santa Barbara has a killer marine sciences
department, and researchers there will be able to
use the spill to study how oil affects the
biogeochemistry of marine ecosystems. The spill
will actually create opportunities, Miller says.
Hes the head of a program funded by NASA and
NOAA to observe and measure marine biodiversity
trends in Santa Barbara, and hes eager to see
what they can learn from the spills aftermath.
Other researchers might try testing oil-eating
microbes, or gather data that could help in
developing new technologies for cleanup crews.
By Thursday night, 17 cleanup vessels managed by
the company whose pipeline rupturedPlains All
American Pipelinehad managed to slurped up just
about 9,500 gallons. Halpern says he expect the
majority of the spill to be cleaned up in a few
weeks, just in time for the last grey whale
stragglers to make their way through the Santa Barbara Channel.
