Woods Hole Oceanography Institute: Photosynthesis vs. Chemosynthesis

Why have we had ice ages in the past? This resource explores the reasons why the earth's climate has repeatedly changed to create ice ages. A quiz is available to check your understanding.

What causes the circulation of ocean waters that are too deep to be affected by wind? Find out how salinity and temperature drive the deep sea currents. This resource has several videos and an online quiz.

In this experiment, students look at Deep Hypersaline Anoxic Basins, or DHABs, that are present in the Eastern Mediterranean, and make a model of a DHAB to investigate how liquids that have different densities can form layers. This...

View several pictures of ocean life through the eyes of scientists and staff at Woods Hole Oceanography Institute. This particular slideshow highlights how ocean creatures change their colors in order to either hide from or frighten...

Find out how scientists at Woods Hole Oceanography Institute use radiometric dating to figure out the age of volcanoes. A slideshow of the history of radiometric dating can also be viewed.

A non-profit center for applied ocean and physics engineering, biology and marine chemistry and geochemistry with a focus on physical oceanography.

A detailed, interactive look at the mid-oceanic ridge. Learn more about slow and fast spreading ridges and how the polarity of the ocean floor helps determine the speed of spreading.

Explains what ocean trenches are and why they are important. Includes links to videos, additional articles, and information about some deep-ocean submersibles.

An interactive timeline will guide you through the history of oceanography. The timeline stretches from 30,000 BCE to the present.

This webpage has two videos related to mid-oceaninc ridges. One of them examines the traits of hydrothermal vents and why their study is important. The other one describes the process by which new oceanic crust is created.
