Marine Food Web

I was a Bull Shark. The Bull Shark eats almost anything, fish, dolphins, birds, turtles, squid, anchovy you name it. If one animal were to become extinct then the whole ecosystem would be destroyed. First one animal would have no food then that animal would slowly die, then another animal would lose food and so on.

Phytoplankton:
We examined Diatoms through a microscope. We then had to draw what we saw, which at first was difficult. However we learned that some things are more important than others and we had to take advantage of that.We also learned that Diatoms are in Toothpaste.

Energy Flow:
Energy flows through the ecosystem because Earth is an open ecosystem.

Human Impacts:
If Humans were to be destructive to the marine ecosystem then we could potentially extinct an animal which could destroy the ecosystem.

Oceanography was a very fun course, learning everything that is to know about the ocean. I learned many new things in this class. During this course we learned a numerous amount about the ocean and did a lot of labs.  There is so much living matter within the waters, and we hardly even know the half of it. We learned a lot about different historical figures as well such as Charles Darwin and Christopher Columbus. These historic figures were important to understanding how the history of our ocean originated. We also learned that most Hurricanes happen in the Summer because the temperatures are warmer. We also learned that the moon has a lot to do with the ocean and what and when tides happen. We also learned that deeper down in the ocean the water density is more dense which makes the water less warm. These new things i have learned during Oceanography give me a new sense of what is really going on in our Ocean. It also showed me how much more we need to figure out and how much of our ocean is truly a mystery. 

Hydrometer

We built a hydrometer using zinc balls. We put the balls in a dropper. We continued to add zing balls until the plastic dropper stood straight up in the water without touching the bottom. Once it was balanced we continued the process of adding zinc. If it started to not float we added salt which balanced out its salinity.

1. salinity: relating to salts
2. It will float highwe
3. H20
4. In the ocean
5. Density

Its all connected

Wind patterns greatly influence the currents in Oceans. The reason is because the wind pushes up against the water and constantly pushes the waves in that direction. Water is constantly in motion and in flux because of the weird directions of the winds. Water from Antarctica is always colder than water from the Equator, which makes sense because the Equator is a lot warmer than Antarctica.  It is stronger there than any other part of the globe. In 1992 many rubber ducks were abandoned in the ocean and scientists tracked where they ended up which totally helped scientists research water and wind patterns on the globe. The air towards the equator brings a lot of moisture and heat. Anything a hurricane touches would greatly effect where it ends up as it would send it soaring any which way. The warm water attracts sharks/whales and other tropical sea critters. Its a good thing there is international law because with only local law things would constantly be ignored. Constantly damaging the ocean is a terrible way to live as the ocean brings us many nutrition such as seafood and other natural habitats in which our animals live in. Without the ocean the world would not survive, yet it is not treated as such a commodity.
