Humans and the Ocean

Oceans have so many different kinds of animals living in them. Yes, we have plants to do photosynthesis but it helps to have water plants doing it too. If we didn't have the ocean I feel like we would have a bunch of animals that we eat or don't eat that would never have existed. We can used currents to move ships from one side of the earth to the other. If we don't take care of the ocean now we will pollute it so bad that all these animals that affect the food chain will die off. Once they die off it will eventually get to the humans and we will die. It also is a big part of the water cycle. The ocean creates a new world of adventures. There are places we haven't even been that are mysterious.

Humans and Coral Reefs

1. Coral Reef gives many homes to animals. This provides safe places for those animals to also give birth to their offspring. Coral reef also protects the inland from Hurricanes. Because lots of animals live in the reefs it also helps make money by bringing in fish for fisherman. Humans use coral for medicines. Due to coral being so pretty it also attracts tourist.
2. When humans help protect the coral they will bring in more money. If we help protect them it will benefit both humans and coral. Coral by keeping it alive for animals, and us for money, medicine, and fish. I don't think either will lose. It doesn't hurt us to help them, all we have to do is make sure we don't  pollute the water with alien like creatures to them.

Human and Kelp Forest

1. Kelp not only provide homes for animals but also they are food for animals. So the animals eat kelp and we hunt the animals. Kelp is one of the starters of the food chain. They take in the suns energy to make photosynthesis and the become food for other animals. Humans also use kelp to make ice cream and toothpaste. There are also many other things kelp is used for.
2. Kelp like really big rocks to cling on to so their dominate environment is rock. So if the environment changes to sand they will decrease fast because they have nothing to cling on to collect the nutrients they need. Rocks can be changed in various of ways: erosion, sediment, and animals breaking them apart.

Coral Reefs

1. They get their food from the sun and algae.
2. They live in warm water because they don't need to float up.
3. They live with lots of nutrients because it helps their photosynthesis process.
Derricks has lots of Kelp because he has a cold current and kelp like cold water. Treyton and I have little or none because we both sit on hot currents. Him on the Equator and me and the Tropic of Cancer.

Kelp Forest

1. Cold water because they float better.
2. They prefer water with lots of nutrients to help their photosynthesis process.
3. Derricks has lots of Kelp because he has a cold current and kelp like cold water. Treyton and I have little or none because we both sit on hot currents. Him on the Equator and me and the Tropic of Cancer.
4. Kelp forest need cold currents to stay afloat. On the coast of California it's the Pacific Ocean and is cold. The farther up you go it would get colder due to the poles, but the farther you go down towards the Tropic of Cancer it will start to warm up and kelp doesn't like warm water. Also towards the shore you get more nutrients from runoff and that provides the kelp with more nutrients. There is also a river that runs towards the ocean from that side.


Phytoplankton

1. Far from land because that is where most upwelling occurs.
2. No, because rivers are freshwater and they would sink. The advantage of being by a river would be the Nutrients. Disadvantage would be phytoplankton are not as abundant.
3. They are more abundant by nearby coast because estuary are freshwater and phytoplankton don't like it.
4. Shallow water because they can get more sunlight to produce photosynthesis.
5. Phytoplankton are more abundant in cold surface water because they can float better to get sun and the nutrients remain longer in cold.
6. Phytoplankton are more abundant in upwelling because during that process it brings nutrients and holds the plankton towards the surface to get more sun. In downwelling it brings up cold water so the warm water moves down so the plankton wouldn't float as good and nutrients get pushed down also.

   I decided to color red on the 21º N because at that point my two currents push away from each other creating upwelling. If we go to high we get into the Tropic of Cancer which is hot water and they can't float as well. But by Pearl Harbor I didn't think there would be very many plankton because the fresh water runs into the ocean.
   Around Hawaii's shores are very shallow until you get farther out. Due to this I think plankton has a closer distance to the suns rays. Only things stopping a lot of plankton would be the warm waters. The higher latitude in Hawaii the lower plankton level.
   The latitude of my island is about 21º-22º N. I am in a tropic climate due to being so close to the Tropic of Cancer.
  During our Spring season the Equitorial Low moves up towards Hawaii so it would increase in plankton because the upwelling would fall right by Hawaii and the waters would cool but the opposite would happen during our Fall times. The sunlight falls right on Hawaii so plankton have plenty of sun but it also depends on the temperature of the water. The best fishing time would be in Spring because that is when you have a more abundant of plankton that the fish eat.

Buoyancy Force Lab

In this lab we had to measure the newtons of cubes in and out of water. The constant volume was about 25cm3. We had 4 different cubes. Tim, F, C, and G. This shows us that Fresh water is less dense than Salt water but alcohol is less dense than freshwater.
