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 (shown here): 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. 5:
Fecal pellets are about the size of a comma (,).
