Introduction to solutions

Offshore Wind Turbine Deep Sea Sequestering

Explanation of electricity generation w physics --> how wind energy works (Wonwoo)

The ecological ramifications of wind energyAlthough wind energy benefits us, it distracts

marine animalsvibration- vibration cause water movement,

which gives distraction to fish, and its noise can disturb marine mammals’ vocal communication

Electromagnetic field- the field distracts fish that are relying on geomagnetic field when moving

As a result, marine animals migrate to different area or modify their behavior.

Biology Experiment 1-1:Aim: To make improvements in offshore wind

farm from disturbing fish and its environment regarding effect of vibration and electromagnetic field.

Procedure:Simulate offshore wind farm

Make a large fish tankUse electric fan as a wind turbine

Result:•Control: no materials•Solution 1: planting water plant near the fan•Solution 2: netting around the fan•Solution 3: covering base of the fan with gravel

Biology Experiment 1-4Conclusion:Solution 1 would

likely be the best solution for reducing distractionsmost fish were

staying for two 30 sec and then half staying for a 30 sec

result of S1 is constant compared to other solution
