We spent the whole day on this trip, but not actually that much time at odiorne itself. We only spent like two and a half hours at odiorne, and one of those hours I played football. But the one and a half hours I did spend tide pooling there was a lot of life. I spent most of the time catching crabs, but I also saw things like snails, urchins, and eels. When we got ice cream, I got a very oversized kiddie blueberry ice cream.
Tides occur because of the moon's gravitational pull. The side that is facing the moon’s water is pulled a little bit towards the moon, raising the water level. The other side opposite of the moon also gets pulled, because of oscillation. The sides being pulled are the high tides, and the rest are the low tides. As the earth spins, the tides will move across the face of the earth, giving you two tides.
There are four intertidal zones. Intertidal zones are elevations that will be covered in water at only certain tides. The four zones (ordered from least time in water to most) are called the black zone, the white zone, the brown zone, and the red zone. The red zone is dominated by irish moss, a red plant that needs a lot of water, but doesn’t need it ALL of the time. The brown zone is filled with kelp that can survive outside of water, but doesn’t really function unless it’s in water. The black zone is covered in cyanobacteria that needs a little water, but not much. The white zone is just like the black zone, but it has cruesents like barnacles.
I saw a lot of shell fish, like crabs, and barnicles, and snails. I also heard that people saw lobsters, but i didn't see them myself. I also saw a bunch of sea weed, kelp, and other plants like that. There was also urchins, and i saw an eel.
I think there is the most variety of life in the red zone, because there is life there that can live in the other zones, but there is also life there that could only live in the red or subtidal zones. For example, crabs could live in the red zone, as well as all of the other zones. But irish moss can only live below the red zone, so there is more life in the red zone.
