Caption from The Ocean Twilight Zone's Role in Climate Change report, pg. 7:
Left (shown here): A microscope image of marine snow shows cylindrical fecal pellets and other aggregates, planktonic tests (round white objects), transparent snaillike pteropod shells, radiolarians, and diatoms. This sample, recovered in 1977 from the bottom of the Sargasso Sea, showed that “packages” of carbon and other nutrients could descend to the seafloor through the water column. Right: A sample collected by WHOI’s Twilight Zone Explorer instrument includes an intact fecal pellet, most likely from a fish. A pellet like this would likely sink very quickly, carrying carbon with it.
Caption from Oceanus magazine, Vol. 40, No. 2, Pg. 2:
One of the first photographs of a sediment trap sample shows cylindrical fecal pellets and other aggregates, planktonic tests (round white objects), transparent snail-like pteropod shells, radiolarians, and diatoms. The first deep-sea sediment trap was recovered on February 20, 1977, from 5,367 meters on the Sohm Abyssal Plain in the Sargasso Sea. As Sus Honjo and colleagues viewed the samples under a microscope, they confirmed a theory and began to solve the mystery of how benthic animals receive nourishment fro surface waters in "packages" that descend through the water column.
