This site provides information on the many aspects of the study of the sea surface from space. Measuring the ocean surface topography provides information for studying global ocean circulation and the oceans heat budget. Regular scanning of the ocean surface to maintain a database of ocean surface topography can help predict short-term changes in weather and longer-term patterns of climate. Educational ...

Until recently, the total energy imparted to the oceans from the moon's gravitational pull has not been fully accounted for: about 30 percent had seemingly vanished without mathematical explanation. The total energy dissipating along the world's shallow areas and coasts don't add up to the expected total. However, data collected by the U.S./French satellite called TOPEX/Poseidon may provide the answer. ... Full description.

Estuaries are partially enclosed bodies of water along coastlines where fresh water and salt water meet and mix. They act as a transition zone between oceans and continents. This site examines various aspects of estuaries, focusing on the geological features that make an estuary, as well as the water circulation patterns by which they are classified. It also has a section that allows the user to access ... Full description.

This site uses data from ocean drifting buoys to integrate ocean science into classroom science and math instruction. Opportunities exist to enhance lessons with suggested educational activities and curriculum materials developed and tested by teachers. Teachers can also use only the data, background information and reference images to supplement existing curricula. Data is collected by the National ... Full description.

This computer-based lesson provides information on ocean currents, circulation and atmospheric influences. Several sections cover "drift" studies, including the famous Nike Tennis Shoe study. Each segment provides relevant information and gives students questions to answer. Incorrect responses result in more information. This unit is part of an on-line course in general oceanography offered at San ... Full description.

In this National Geographic Xpedition lesson, students learn about ocean waves. They begin by learning the components of a wave, and then discuss the meaning of wave height and wavelength. A demonstration sparks discussion about how to make waves, and an activity with the National Geographic Wave Simulator allows students to experiment with creating waves of varying sizes.

This site contains an extensive list of frequently asked questions and short answers regarding the characteristics of icebergs. In addition, there are links to detailed descriptions of the six main types of icebergs, other interesting facts about icebergs, and photographs of Newfoundland icebergs. Full description.

The International Ice Patrol is a branch of the United States Coast Guard. They monitor iceberg danger near the Grand Banks of Newfoundland, and provide the limits of all known ice to the maritime community. This kids page provides an illustrated story of the life cycle of icebergs, as well as a list of questions and answers about icebergs in general. There is also a set of links to other sites that ...

The site focuses on the responses of Antarctica and its sea ice to climate changes. Two experiments help illustrate what happens as water warms and how this warming could affect sea levels and low-lying coastal areas. Links to more detailed information are also provided. Full description.

Visitors can find answers to frequently asked questions regarding sea level and sea level changes. Topics addressed include how mean sea level is defined, how much sea level would rise if all the world's ice were to melt, differences in sea level between oceans and at different latitudes, the meaning of altitude above sea level, and others.
