Sea Life of the Monterey Bay

Oh Seth, you had to ask to learn more about sea life in the region. Today started the biology section of the institute. Little did you know that I'm way over my head in marine biology terms at the moment. Things like the differences between "lottia digitalis" and "siphonaria maura," for example. Or looking at the effects of "Pacific Decadal Oscillation" on pelagic communities. We're working with a holistic biologist** from Stanford, the director of Hopkins Research Station, and a senior scientist from the Monterey Bay Aquarium Research Institute. Understanding that the majority of teachers aren't science teachers, we got some interesting comparisons such as acrea based on "universality of niche" to Tom Joad's final speech in The Grapes of Wrath, and a line of poetry to the jelly(family) food web.

Here are two creatures from the Monterey Bay that I can almost guarantee will be new to most of you.

The first is the vampyrus (vam-pyro-tooth-us) infernalis. Even though of you without a strong Latin background might notice some similarities to modern English words.



It's a "living fossil." When it's threatened, it assumes a pineapple posture to protect it's mantle by placing its arms in a protective posture. As if that weren't enough, it also squirts bio-luminescent particles from its arm tips that create an enormous and distracting display around itself.



The second was only discovered in 2007, and it was given the name "chetopterus pugaporcinus." You're welcome to translate, but I'll hint that the name is based on the appearance.




In the last 15 years, Humboldt squid have shown up in great numbers from more tropical climates due to rising water temperatures, reduced oxygen in the water, reduced competition, and reduced predation. They're depleting the hake fish population. I don't know if they're considered an invasive species, but the researcher used the word "invasion" to describe what's happened.




It's late, and we need to read The Tragedy of the Commons and several responses for our morning sessions tomorrow. Feel free (except Seth) to skip the next part. It's taken directly from my notes.

When European explorers arrived on the California coast in the 18th century, fish and wildlife were plentiful. Grizzly bears fought on the coast over sea life that washed up on the beaches, and condors ate from the sea as well. Between 1789-1811, 39,173 sea otter pelts were taken. Each pelt could be sold to the Chinese for 30 dollars at a time when 90 dollars bought you a house in San Diego. But, otters play an important role in the ecosystem. They protect sea kelp forests by eating sea urchins and abalone who eat kelp. Because the California waters are cold and sea otters lack blubber, every adult sea otter ate approximately twenty pounds of seafood each day. The kelp forests were devastated. This set a pattern where people hunted animals to extinction, altered the ecosystems, and found new animals to hunt. In order, they hunted otters, whales, seabirds, and abalone. (I'm not including the sardines and canning industry. I could.) Meanwhile, in the early 20th century, Julia Platt, Ph.D., fought against the pollution of the canning industries. She broke glass ceilings all over the world, and she even became mayor of the town of Pacific Grove when she found out she would have the power to create a marine conservation area and wildlife refuge if she did so. Onto the 1930s and sea otters were thought to be extinct. While building the Bixby Bridge on US1, a colony of 30-50 was discovered. Fishermen wanted to shoot them because they ate abalone, but some were moved to Monterey Bay. The otters liked the marine area, and soon the kelp forests began to rebound. With the kelp forests came more fish and with more fish came the seals. The seals brought tourists as well as the interest of Julie Packard (of Hewlett-Packard money) who helped conceive of and fund the Monterey Bay Aquarium. It's one of the best research facilities for aquatics in this country, and it's also increased tourism to the area. (Tourism is now the second largest industry behind agriculture. There's more wildlife viewing than wildlife processing, and maintaining a healthy ocean has become part of the economic model.

**Holistic biology is really interesting. It started for the non-science majors at Stanford because they were overwhelmed by the science focus of the school. It encourages students to examine systems and communities (as Ed Rickett's recommended) as an integrated whole.

****I saw my first two sea otters out in the bay this evening. They're just as cute as I expected. It was even better because it was a chance occurrence that I walked out back during the 5 minute break.
