Before revision: Determination of climate history Biogenous ooze, and other pelagic sediments can be collected form the seafloor and used to reconstruct Earth's climate for the last 100 million years , also known as paleooceanography .
After revision: Determination of climate history In the fields of paleoceanography and paleoclimatology, biogenous ooze and other pelagic sediments can be collected form the seafloor and used to reconstruct Earth's climate for the last 100 million years .
