"I Found The City Under The Sea" by Jack Kirby

A new study shows that animal communities on the abyssal seafloor are affected in a variety of ways by climate change, some changes occurring within a few weeks.

Available food there is takes the form of bits of organic debris drifting down from the sunlit surface waters, thousands of meters above. It is estimated that less than five percent of the organic matter produced at the surface reaches the abyssal plains. Research shows that the amount of food reaching the deep sea varies dramatically over time.

Some relevant ocean processes that may be affected by climate change include wind-driven upwelling, the depth of mixing of the surface waters, and the delivery of nutrients to surface waters via dust storms. Climate-driven changes in these processes are likely to lead to altered year-to-year variation in the amount of organic material reaching the seafloor. link
