Question: How do you studi the ocean

Silvia Pardo answered on 7 Nov 2016:

I use pictures of the ocean taken by satellites than travel around the Earth. The colors on those pictures tell us if the water is muddy or polluted or full of plants. I study the colors and what they mean: for example, if the waters looks green it means that the water is full of tiny plants and small fish will go there to feed.
