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.
