NOAA Okeanos Explorer Mission Portal

NOAA Ship Okeanos Explorer is the only federal vessel dedicated to exploring our largely unknown ocean for the purpose of discovery and the advancement of knowledge about the deep ocean. Missions of the 224-foot vessel include mapping, site characterization, reconnaissance, advancing technology, education, and outreach all focused on understanding, managing, and protecting our ocean. Expeditions are planned collaboratively, with input from partners and stakeholders, and with the goal of providing data that will benefit NOAA, the scientific community, and the public.

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. Learn more about the DATA Series.
