摘要

The marine biosphere is an essential component of the Earth system which helps maintain conditions crucial for life on the planet. It directly provides about 20% of the food and half the O2 used by humanity. The oceans, especially coastal waters, are important resources for humanity beyond food and respiration needs, including transportation, energy and recreation. Nearly half the global population resides in coastal regions, and the coastal biosphere is increasingly impacted through anthropogenic activities, both intentional and accidental. The marine biosphere influences weather and climate through the ocean heat budget, carbon cycle, and biogenic production of radiatively active trace gases. The world ocean, by far the largest reservoir of carbon on Earth, is a net sink for atmospheric carbon dioxide, and the marine biosphere, in particular, the phytoplankton are responsible for the uptake of carbon by the ocean.
