[[Biogenous sediment]]s account for the other 55% of the total sediment, and originate in the skeletal remains of [[#Marine protists|marine protists]] (single-celled plankton and benthos microorganisms). Much smaller amounts of precipitated minerals and meteoric dust can also be present. ''Ooze'', in the context of a marine sediment, does not refer to the consistency of the sediment but to its biological origin. The term ooze was originally used by [[John Murray (oceanographer)|John Murray]], the "father of modern oceanography", who proposed the term ''radiolarian ooze'' for the silica deposits of radiolarian shells brought to the surface during the [[Challenger expedition]].<ref>Thomson, Charles Wyville (2014) [https://books.google.com/books?id=zcFkAwAAQBAJ&q=radiolarian+ooze ''Voyage of the Challenger : The Atlantic''] Cambridge University Press, page235.
