为什么地球海洋的颜色是不同的?

为什么地球海洋的颜色是不同的?全世界海岸行似乎有不同深浅的蓝色。进一步的从赤道北部或南部海洋变成了深蓝色。这是影响海洋温度和盐度的结果吗?

回答

这个问题来源于身体在世界各地不同的地方,看到不同的颜色。我选择使用蓝色作为一个例子,因为这是地球海洋是通常被称为。我认为有不同的配色方案。* *有几种理论:* * -蓝色波长的光线被吸收了深海的水和最少的散射和反射回观察者的眼睛。——颗粒在水中可以反映出蓝色的光。——海洋反映了蓝天。大多数时候大海似乎是蓝色的,因为这是我们的眼睛看到的颜色。但大海可以许多其他颜色取决于粒子在水里,水的深度,天窗的数量。我们看到的颜色取决于可见波长的光的反射到我们的眼睛。富兰克林研究所提供了一个很好的解释,我们如何在http://www.fi.edu/color/color.html看到颜色。 **Chlorophyll estimation** Chlorophyll concentrations are derived from images of the ocean’s color. Generally speaking, the greener the water, the more phytoplankton are present in the water, and the higher the chlorophyll concentrations. Chlorophyll a absorbs more blue and red light than green, with the resulting reflected light changing from blue to green as the amount of chlorophyll in the water increases. Using this knowledge, scientists were able to use ratios of different reflected colors to estimate chlorophyll concentrations. **Intrinsic Absorption** The reason the ocean is blue is due to the absorption and scattering of light. The blue wavelengths of light are scattered, similar to the scattering of blue light in the sky but absorption is a much larger factor than scattering for the clear ocean water. In water, absorption is strong in the red and weak in the blue, thus red light is absorbed quickly in the ocean leaving blue. Almost all sunlight that enters the ocean is absorbed, except very close to the coast. The red, yellow, and green wavelengths of sunlight are absorbed by water molecules in the ocean. When sunlight hits the ocean, some of the light is reflected back directly but most of it penetrates the ocean surface and interacts with the water molecules that it encounters. The red, orange, yellow, and green wavelengths of light are absorbed so that the remaining light we see is composed of the shorter wavelength blues and violets. https://www.loc.gov/rr/scitech/mysteries/oceanblue.html https://science.nasa.gov/earth-science/oceanography/living-ocean/ocean-colour
