Something that we would do would be to use refillable water bottles so that bottle caps and potentially the bottle that they come in would not go out to the ocean. In these past couple of weeks we learned that an incredible amount of plastic ends up in the ocean, especially bottle caps. Bottle caps cannot be recycled and when they end up in the ocean, animals eat them.  The animals cannot digest them; they build up in their stomachs and die because of this. The ocean currents carry and distribute these bottle caps all throughout the ocean.  Not only bottle caps but also shopping bags and plastic rings that hold six packs together. However, just trying to stop bottle caps from going into the ocean would be a big step to start fixing this problem.seabirds-eat-plastic2

There are many things that we learned about the ocean currents. Ocean currents are a continuous, direct movement of ocean waters generated by different forces acting upon this, such as, wind, waves, the Coriolis Effect, temperature, and the tides. They can flow for a great amount of distance and help determine the climate of many of the Earth’s regions. Surface ocean currents develop their clockwise spiral in the northern hemispheres and their counterclockwise spirals in the southern hemispheres due to the different wind stressors. In wind-driven currents, the Ekman spiral effect results in the currents flowing at an angle to the driving winds. The salinity and the tides cause the gravitational pull of the moon and the sun.
One action that we will take to protect the ocean is to recycle a lot more and to use a lot less plastic in our everyday lives.

In the classroom the major thing I learned is that the Gulf of Maine is not part of the Atlantic Ocean. The Gulf of Maine is separate from the ocean and is its own body of water, even though it is connected to the Atlantic Ocean. Since the Gulf of Maine is directly connected to the Atlantic Ocean I assumed it was considered part of the ocean, but because of the currents the Gulf of Maine is cut off from the ocean. The Gulf of Maine goes from Cape Cod up to the Bay of Fundy in Nova Scotia. The Labrador Current comes into the gulf from the north and turns in a counterclockwise direction inside the gulf. Since the Gulf of Maine is fed primarily by the Labrador Current, which comes down from the north, the water is generally cold.
