How is the energy from waves generated?
Energy of surface waves is captured and converted into electricity.
What are the benefits of the energy derived from waves?
No harmful gas, created by unequal heating or gravitational attraction therefore unlimited. GU
What are the drawbacks of the energy derived from waves?
Not very attractive, impact on ecosystem not known, potential noise pollution. AEN (Attractive-Ecosystem-Noise)
How is the energy from tides generated?
The gravitational pull of the moon and the sun along with the rotation of the earth cause the tides.
What are the benefits of energy derived from tides?
Same as energy from waves.
What are the drawbacks of energy derived from tides?
Impact on estuary plants and animals, increased turbidity of water, impacts navigation. ETN
Define Aquaculture
The farming of aquatic animals or plants principally for food. It includes the breeding, rearing, and harvesting of fish, mollusks, crustaceans, and plants in fresh and saltwater environments. BRH

_____ produces 60% of all farmed seafood.
China
What are the benefits of aquaculture?
Can be a solution to the world’s food insecurity problem-Highly efficient compared to land-based protein. IE
What are the drawbacks of aquaculture?
Overfishing of key species-Fish waste, nutrients, antibiotics, and invasive species. OW
What are the risks of open water net-pen aquaculture?
Invasive Species-Drugs-Escape-Fish Waste-New Diseases/Parasites. IDEWD
Define Invasive Species
If nonnative species are raised in net pens, it could lead to introductions of invasive species into the open waters of the Great Lakes.
Define Drugs
The addition of antibiotics and growth hormones releases them directly into the Great Lakes where they affect wild fish health and public drinking water supplies.
Define Escape
Escaped fish compete with wild fish for land, disrupt their natural reproduction, and can interfere with their genetic diversity.
Define Fish Waste
Concentrated amount of fish waste in a small area.
Define New Diseases
Crowded fish cages are breeding ground for diseases and parasites that could spread from caged fish to wild populations.
The ocean contains a complex combination of _____, _____, _____, and _____ processes that sometimes result in commercially viable forms of a wide range of minerals.

200 nautical miles.
What are some reasons we should mine the ocean floor?
Improve the economies of developing nations-Decrease impact at land-based mining operations-It’s in your EEZ, it’s yours. ELY
What are the impacts of mining the ocean floor?
Destroys the sea floor-Eliminates organisms we don’t even know about-Very expensive. DEE
What technologies are used for deep-sea mining?
Continuous Line Bucket System- Hydraulic Suction Systems CLB HSS
Define The Great Pacific Garbage Patch
The largest of 5 offshore plastic accumulation zones in the world’s oceans; it’s located halfway between Hawaii and California
There are 4 types of plastic sizes that are found in the Great Pacific Garbage Patch. Which plastic has the highest object count in the patch?
The 4 plastic types are microplastics, mesoplastics, macroplastics, and megaplastics; according to the model, 94% of the object count is represented by microplastics.
