Nautilus Live!

The Nautilus Exploration Program focuses on three main areas of marine science: biology, geology, and archeology. No matter what area a particular cruise focuses on, the Corps of Exploration is ready for whatever they may come across in the depths of the sea. Over 95% of the ocean is unexplored, and that number approaches 100% for its deepest regions where the Nautilus team does most of their work. Above all else, Nautilus lives up to its title as an "Exploration Vessel" - each cruise has specific objectives, but the path changes constantly throughout the season as new discoveries come to light.

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.
