NASA Lessons in Sea Level Rise

"Sea level rise" - we hear that phrase, but what does it mean, really? How does it affect us? Do I have to be concerned about it in my lifetime? These are all great questions! Sea level rise is the increasing of the average global sea level. It doesn't mean that seas are higher by the same amount everywhere. In fact, in some areas, such as the west coast of the US, sea level has actually dropped slightly...for now.

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.
