The Galapagos of California: The Farallon Islands.

Every so often the fog retreats from my neighborhood in San Francisco, moves out to sea and we are blessed with a world-class sunset. Adding to the oranges and reds, yellows and spiraling indigos of the evening sky, it also gives us a special chance to see the silhouette of the strange jagged fist of rock breaking up the crisp line of the horizon. I have gazed out upon the Farallon Islands for years. The archipelago is clearly the wildest part of The City-seemingly always just out of reach. (Many people don’t realize that these little islands are actually part of the City of San Francisco.) Since they are a federally protected wildlife refuge, they’re completely closed to the public. So to get a chance to actually set foot on South Farallon Island was an absolute honor.

We’ve tried to share the experience in as many ways as we can. I encourage everyone to really explore the islands through Quest. In addition to the television story, we have a radio presentation with reporter’s notes, a web exploration with video and stills, a unique audio slideshow, an interactive history timeline (also embedded below) and a Flickr set. We’ll also be adding another web-only video story and education guide. The only things we couldn’t bring you are the smell and chill of the wind. But we’ll get on that.

Each year the Marine Mammal Center treats somewhere between 600-1000 animals, including California sea lions, Pacific harbor seals, Northern elephant seals, and steller sea lions. About half of them are treated successfully at the center and released into the Pacific. The other half either die naturally or have to be euthanized.

Most of them end up at the center's hospital after passersby spot the animals on the beach and sense something’s wrong. (The Marine Mammal center responds to calls anywhere between Mendocino and San Louis Obispo Counties — some 600 miles of coastline.) Some problems are human-caused, like boat-propeller injuries or ingested fishing nets and hooks. Other times, it's cancer, domoic acid poisoning, or leptospirosis. Sometimes, it's hard to tell exactly what happened — hence the need for necropsies.

On the day that Quest intern Jennifer Skene and I visited the center, veterinarian Nicola Pussini performed two necropsies, both on sea lions. One animal seemed to have died from a tumor underneath his fin; the other was a suspected domoic acid intoxication.

Each necropsy takes about an hour and a half. First Pussini measures the animal, then he slices it open and inspects every part, from tongue to tail. He inspects the teeth, pulls out all the organs, checks to see how much fat the animal has. The data, along with tissue samples, are archived and shared with other research institutions. This is the kind of basic research that Marine Mammal Center staff cite when people ask why they devote so many resources (most of it from private donations) to animals whose populations are neither threatened nor endangered.

I should mention that I didn't exactly see this entire process firsthand. Let's just say that after my first strong whiff of sea lion intestine, I felt a compelling need to go check on things outside the necropsy room. Luckily for me, Jennifer has the stomach of a true scientist and managed to both hold the microphone and take photos. Luckily for you, we’re sparing you her gorier shots.

Listen to the Sea Lion Rescue radio report online, and watch our photo slideshow.

For these notes, I thought I'd focus on something that didn't make it into the sea lions radio broadcast: the necropsy.
