Oil Spill Quote of the Day

Today’s Oil Spill Quote of the Day features Elizabeth Griffin Wilson, one of our very own scientists:

 From yesterday’s Guardian:

Some 1,020 sea turtles were caught up in the spill, according to figures (pdf) today – an ominous number for an endangered species. Wildlife officials collected 177 sea turtles last week – more than in the first two months of the spill and a sizeable share of the 1,020 captured since the spill began more than three months ago. Some 517 of that total number were dead and 440 were covered in oil, according to figures maintained the Deepwater Horizon response team.

Fact of the Day: Narwhal

Narwhals (credit: Glenn Williams)

You may recognize this funny looking marine mammal as the large, talking cartoon whale from Will Ferrell’s “Elf” but the narwhal (or “corpse whale” in Old Norse) actually is a very real toothed whale that lives in cold, Arctic waters. 

Only male narwhals have the characteristic long tusk, which is actually a super long tooth that can grow up to 10 feet. It is unknown exactly what purpose this tooth serves but scientists do know that it is not used for hunting.

Factsheet: The Timor Sea Oil Spill of 2009

For more, read the PDF of this factsheet.

On August 21, 2009 the Montara oil rig suffered a blowout and began spilling oil. The well was located in 250 ft of water, between East Timor and Australia. It took four attempts over ten weeks to block the leak and it was eventually achieved when mud was pumped into a relief well.

10 Ways the Oil Spill Could Affect Marine Life

While oil-covered birds have become an emblematic image of catastrophic oil spills, sea birds aren’t the only ones affected. Oil is extremely toxic to all wildlife, and the toxic effects on marine life begins as soon as the oil hits the water.

 


Here are 10 examples of how marine life may be affected by the Gulf spill in the coming days, weeks and years

Oil Spill Threatens Hundreds of Species

It just keeps getting worse.

A NOAA scientist has concluded that oil is leaking into the Gulf of Mexico at the rate of 5,000 barrels a day, five times the initial 1,000 per-day estimate. And a third leak was discovered yesterday afternoon. 

If the estimates are correct, the spill, which is nearly the size of Jamaica, could match or exceed the 11 million gallons spilt from the Exxon Valdez within two months -- becoming the largest oil spill in U.S. history.

Where Are They Now?: Chanel Gemini, Nika Kashyap & Sabina Van Tilburg

This is the fourth in a series of posts about the 2009 Ocean Heroes finalists.

Today we’re catching up with 2009 ocean hero finalists Sabina van Tilburg, Chanel Gemini and Nika Kashyapone, the three girl scouts who were instrumental in convincing the state of Hawaii to become the first state in the U.S. to officially recognize World Oceans Day. They obtained over 650 signatures on their petition and received the support of many non-profits and government agencies such as the Nature Conservancy and NOAA.

Here’s Sabina's update:

“As a Girl Scout troop, we are currently working on our Gold Award, the highest award for Girl Scouts and selling lots and lots of cookies! We have recently been focusing on recycling, gardening, buying local, and learning more about our community. Along with that we have been participating in a lot of beach clean ups, fishpond clean ups and restorations, working in the lo'i which are Hawaiian taro patches, and counting whales with NOAA, which you can learn more about at http://hawaiihumpbackwhale.noaa.gov/involved/ocwelcome.html "

Inspired? Nominate someone you know -- young or old -- to be this year's ocean hero.

Whale Wednesday: Sushi Sting

On this hump day, a few cetaceous stories for your perusal:

As you've probably heard, the team behind Sunday’s Oscar-winning documentary “The Cove” exposed Santa Monica sushi restaurant The Hump for serving illegal whale meat. The possession or sale of marine mammals -- in this case, the endangered sei whale -- is a violation of the Marine Mammal Protection Act, and can lead to a year in prison and a fine of $20,000.

And on the brighter side, the BBC has a remarkable slideshow of images showing a sperm whale surface feeding off the coast of New Zealand. Surface feeding is uncommon for sperm whales, who usually hunt many meters below the sea’s surface -- this individual must have been pretty hungry.

Whale Wednesday: Squid Herding?

BBC News reports that Oregon scientists using impressive tagging technology have shown that sperm whales may work together in a kind of zone offense to hunt their squid prey.

The researchers have evidence of the whales staying together over several months in the Gulf of Mexico. And their behavior varied with each deep dive, indicating that they alternate roles to spread out the physiological demand of the 1,000-meter dives.

One researcher said that the some whales appeared to guard the bottom of a squid bait ball, while others took advantage of the center of the ball.

Other research has suggested dolphins may exhibit herding behavior, but this is the first evidence in sperm whales; some scientists remain skeptical.

Just remember, whales: there is no "I" in "team."

Jean-Michel Cousteau On Orcas

"When you take a wild cetacean (a whale or dolphin) and put it in a tank, its acoustic system is suddenly screwed up. Its sonar reverberates off of the concrete in its tank and, little by little, the animal becomes totally silenced. It’s like a person being blindfolded in a jail cell. The orcas are not used to borders or barriers, and that probably makes them very uncomfortable. Some of them don’t accept captivity and die, but others do and live like they are in prison."

That's Jean-Michael Cousteau reflecting on killer whales in the wake of last week's death of a trainer at Sea World. Cousteau is one of the world's experts on orcas and gives a fascinating, wide-ranging interview to the Santa Barbara Independent about whales and dolphins in the wild and in captivity, including a description of the enormous effort it took to rehabilitate and free Keiko, the orca that starred in "Free Willy." It's well worth a read.
