Bridge DATA Series Bridge DATA - Diatomaceous Sediments: Ooze Clues Just as ocean beaches display a variety of sand types, the ocean floor has different sediment types. Sediments can come from land, living organisms, chemical reactions in the water column, and even outer space. When skeletal remains of microscopic organisms make up more than 30% of the sediment, it is called "ooze." In this activity, students will plot the distribution of various oozes using information from sediment maps. The Bridge's own DATA Series is made up of lesson plans (DATA Tips) on many ocean science topics that explore the world of water using the language of science: mathematics.
