oozes

Oozes are sediments on the deep-sea plains, consisting of plankton remains, wind-borne volcanic dust, etc. Beneath about 5,000 meters no organic matter is present (red clays); between 5,000 and 3,900 meters Radiolaria predominate in the siliceous oozes; and between 3,900 and 2,000 meters Foraminifera (especially Globigerina) are most common in the calcareous oozes.
