This collection of basic definitions and answers to questions about hurricanes and tropical cyclones includes how they form, how they are named, how intensities are measured, and how storms are forecast. Historical information, information on myths surrounding these storms, links to sites displaying real-time storm information, and safety tips are also included. Full description.

This site contains information about discoveries made after World War II when ocean-going geologists adapted sensitive magnetometers developed for antisubmarine warfare for use in seafloor research. This modern technology gave geologists their greatest boost in more than a century of field work and led to the idea of sea floor spreading. This site has animations showing sea-floor spreading and a magnetometer ... Full description.

This interactive, animated globe allows users to rotate it and change the virtual sea level by up to 200 meters, observing which areas are inundated. Full description.

In this activity, students use a graph to find sea level at various times in the past, then draw the ancient coastlines onto a bathymetric map by following the depth contours. They should develop an understanding of how to interpret a graph to discern changes in sea level, and an understanding that ancient coastlines parallel the contour lines on a bathymetric map. A materials list, directions, background ... Full description.

In this activity, students create artifical convection currents using hot and cold water, food coloring, and bottles. A materials list, instructions, and a brief explanation of the convection phenomenon are included. Full description.

In this activity, students learn what happens to cool, deep water in the ocean when the warm surface water is moved away. As they demonstrate the process of upwelling, they will understand the concept that wind patterns and currents may cause cold water to rise from deeper areas. Background information, a materials list, and instructions are provided. This activity is designed to accompany the film ... Full description.

This reference provides an overview of the three zones into which the ocean can be divided based on the amount of light recieved: the sunlit (or euphotic) zone, the twilight (or disphotic) zone, and the midnight (or aphotic) zone. The descriptions are accompanied by diagrams and a brief listing of the organisms that live in each zone. Full description.

Visit to an Ocean Planet is an innovative CD-ROM that has been transferred to the web. Visit to an Ocean Planet is for grades 5-12 that makes science, ocean, climate and life education fun and interactive. There are three sections, expedition, mission and guide. The expedition section engages students in exploring the 1997 El Nino, a look at oceanographers and their work, and an ocean science research ... Full description.

This is the home page for the National Oceanic and Atmospheric Administration (NOAA). The goal of the National Oceanic and Atmospheric Administration is to describe and predict changes in the Earth's environment, and conserve and wisely manage the Nation's coastal and marine resources. This page provides access to the many component organizations, educational resources, and opportunities at the National ... Full description.
