co2水体碳汇潜力

co2水体碳汇潜力
英文回答：
Carbon dioxide (CO2) is a greenhouse gas that is released into the atmosphere from human activities such as burning fossil fuels. The ocean can act as a carbon sink, absorbing CO2 from the atmosphere and storing it in the form of dissolved inorganic carbon (DIC). The potential of the ocean to store CO2 is known as the ocean carbon sink potential.
The ocean carbon sink potential depends on a number of factors, including the solubility of CO2 in seawater, the availability of nutrients for phytoplankton growth, and the circulation of the ocean. The solubility of CO2 in seawater decreases with increasing temperature, so the ocean carbon sink potential is expected to decrease as the ocean warms. The availability of nutrients for phytoplankton growth is also important, as phytoplankton take up CO2 during photosynthesis. The circulation of the ocean is important
for transporting CO2 from the surface to the deep ocean, where it can be stored for longer periods of time.
The ocean carbon sink potential has been estimated to be between 2 and 4 petagrams of carbon per year. This is a significant amount of carbon, and it is equivalent to about one-third of the CO2 emissions from human activities each year. However, the ocean carbon sink potential is not unlimited, and it is expected to decrease as the ocean warms.

二氧化碳 (CO2) 是一种温室气体，由燃烧化石燃料等人类活动释放到大气中。

海洋可以作为碳汇，从大气中吸收二氧化碳并将其以无机溶解碳 (DIC) 的形式储存起来。

海洋储存二氧化碳的潜力被称为海洋碳汇潜力。

海洋碳汇潜力取决于多种因素，包括二氧化碳在海水中的溶解度、浮游植物生长的养分供应以及海洋环流。

二氧化碳在海水中的溶解度随温度升高而降低，因此随着海洋变暖，海洋碳汇潜力预计会下降。

浮游植物生长所需的养分供应也很重要，因为浮游植物在
光合作用过程中会吸收二氧化碳。

海洋环流对于将二氧化碳从地表输送到深海（可以在那里储存更长时间）非常重要。

海洋碳汇潜力估计在每年 2 到 4 拍克碳之间。

这是一个巨大的碳量，相当于人类活动每年排放的二氧化碳的三分之一左右。

但是，海洋碳汇潜力不是无限的，预计随着海洋变暖而下降。
