When we got to school we got into two seperate buses so we could fit the whole grade. We started on our journey and had a very quiet uneventful ride too odiorne. Just kidding we were horrible little devil children and we wrote on eachothers faces, it was so fun! When we got there we walked across the sidewalk until we saw the ocean. Then we dropped our bags at the picnic tables and raced down to the water. Whithin minutes we were finding creatures great and small like sea stars, sea urchin, crabs, lobsters, and many plants. After we were satisfied with our finds we walked back up the hill over the rocks to eat lunch and play football or wiffle ball. After around 30 to 60 minutes of that we left on the busses and started home. We stopped for a giant cup of ice cream on the way back.
Tides occur because of the gravitational pull of the moon. The moon pulls water towards it making a slight bulge of water on one side of the earth and there is another bulge on the opposite side as well. That is due to the moon pulling the earth away from the water on that side. And as the Earth rotates and the Moon moves around the Earth in a pattern the tides go in and out (High tide and low tide).
At odiorne point in Rye, New hampshire there is a really awesome place to go tide pooling. It is on a hill and as you walk down the hill you go through multiple tidal zones. The first one is called the black zone, which is called this due to the black algae that covers the rocks. The next zone you walk through is called the white zone because there are barnacles all over the rocks. When we got there that was around were the water reached. After that you wade through the brown zone that has a lot of sea weed called Knotted wrack or rockweed. This is where you will start to find some crabs, small lobsters, sea urchins, or sea stars. As you get to the red zone, which has lots of Irish Moss floating in the water. It starts to get deeper in some spots up to your mid thighs. You can also find a lot of the same species as in the brown zone.
Whithin a minute or two of stepping in the water I had already found multiple hermit crabs and small green crabs not to mention a lot of knotted wrack, rockweed, and Irish moss. And after I waded out deeper I found two large green crabs and a sea urchin or two. And after around 30 minutes I had found seven more sea urchins! Once I even found three under the same rock! I was about to head in for lunch when I had my greatest find of the day... A daisy brittle star!
I think the most variety of creatures is in the brown zone. There are multiple reasons I think this, for one it is in the middle of the zones so it has around the average water level that most creatures need. Another reason I think this is because it has a ton of Seaweed floating on the top of the water that provides good shelter from humans seeing them and the sun. In this zone we found sea urchins, crabs, lobsters, barnacles, sea stars, tunicate, and mussels.
