Saturday Morning, 7:30 a.m., On the Bay
Amazing Bay Day, Sept. 29, 2007 at the Marine Science Institute in Redwood City.
Girl Scouts Save the Bay. Yes, we will!
We arrived at the Marine Science Institute a half-hour early, expecting to the first ones there. Instead, the parking lot was overflowing and girl scouts were roaming the grounds, brimming with excitement. We were attending just as a family, but the rest of our boat were two or three troops along with lots of parents. Being by ourselves had an advantage, but I'll get to that in a minute.
It had been cloudy and drizzly all night, but today there wasn't a cloud in the sky. The only other boats out at that time of morning were the rowing teams.
After a safety briefing, they started the program. Wini's first assignment was on the otter trawl crew.
The net is thrown into the water and dragged by the moving boat for a few minutes to catch fish. During the dragging, the MSI staff instructed the girls on what types of fish to expect and explained the physical characteristics of fish from different strata of the bay. Here, the buoy floating in the distance shows how far back the net is dragging.
We were pretty far out by then between the Dumbarton and the San Mateo bridges. Two other crews of girls hauled big ropes that dragged the net most of the way to the boat, and the otter trawl crew finished hauling it up. The catch: mostly anchovies, some sort of spider crab (I didn't see it, but heard the girls talking about it) and some flat-as-a-pancake bottom dwellers. The girls were allowed to touch them with two fingers, avoiding the eyes. Turns out anchovies eat plankton and their jaws expand to a huge size. Staffer Jayo demonstrated by sticking his finger behind the jaw of a a deceased anchovy.
A volunteer counts, measures, and catalogs every fish that is caught. This bin contained the anchovies that had already been measured. About a quarter of the anchovies were dead, probably killed by the net.
It was time to wander the ship a bit and look around.
This is where not being with a troop was an advantage, as Wini went up to the wheel room and made friends with Captain Jackson. He let her turn the boat.
Next was a mud grab. Again, they had a system that gave every girl a job. The contraption is a box that they lower to the bottom of the bay. It snaps open on impact, then snaps shut when it's pulled up, grabbing mud and other goodies. Two girls monitored the ropes on the side, giving slack or tightening as needed to swivel the arm sideways. The other girls lined up and lowered the heavy box, then pulled together to haul up the even heavier mud. Wini was one of the side girls, and she had to tie off her side by herself.
Here's the box being lowered.
And here it is on the way back up. You can see a sponge hanging out of the bottom! Other cool stuff were some blood worms caught in rocks, shells, and lots of mud.
We looked at plankton under a microscope, but that was indoors and too much for my seasick-prone stomach, so I was busy staring at a fixed point in the distance for the last 20 minutes. All too soon, we were back among the rowers and taking off their life vests. Then we all took the Girl Scouts Save the Bay pledge:
On my honor I will try:
To protect and restore
Our San Francisco Bay,
My home.
I will do my best to:
Use water wisely,
Recycle everything I can,
Appreciate the beauty of The Bay,
and Make the world a better place.
