||Deep sea substrates that are composed of > 30% tests, shells, or frustules of small plankton, including diatoms, radiolarians,
pteropods, foraminifera, and other marine plankters. Oozes are common in deeper waters far from shore, where terrestrial inputs
to the bottom sediments are very low, and where surface productivity is reasonably high. Based on common practice in the field,
definition of a substrate as "ooze" requires a 30% or greater (but not necessarily "dominant") ooze composition within the
sediments. Once defined as an "ooze", type of ooze is determined by dominant percent composition.
