Detecting El Niño in Sea Surface Temperature Data
SST anomalies for December 1997 displayed in My World GIS™. Red indicates above average temperatures compared to average SST temperatures for December data averaged over the years 1982-1998. This chapter introduces you to normal seasonal sea surface temperature (SST) variation as well as extreme variation, as in the case of El Niño and La Niña events, in the equatorial Pacific Ocean. You will learn how to download seasonal SST data from the Pacific Marine Environmental Laboratory (PMEL), via a THREDDS server, for the years 1982 to 1998. With My World GIS, you will visualize and analyze that data, looking for the tell-tale SST signature of El Niño and La Niña events that occurred during that time period. At the conclusion of the chapter, you will be given the opportunity to analyze a season of your own choosing to determine if an El Niño and La Niña SST pattern emerged in that year's data.

Natural Hazards: Floods

This site contains an interactive map of recent worldwide flood events. Clicking on the icons on the map will display satellite imagery and a detailed description of the flood events. Information in each description includes time and date of the event(s) as well as cause and effects of the event(s). Users may also choose to follow hotlinks to the detailed flood event information. This site is part of NASA's Earth Observatory, Natural Hazards division.

SeaWiFS: NASA Carbon Cycle Initiative

SeaWifs 3 year data of the pulse of the planet, helps show the Carbon Build up in the air. For this presentation the Scientist wanted to show how the earth reacts to the chemicals in the air.

Mantle Convection

This page discusses thermal convection as it applies to the Earth's mantle and includes three QuickTime movies for three different cases of convection: heating from below, heating from within, and a combination of the two.

Farallon Plate Remnants

This image and short video from the NASA's Scientific Visualization Studio shows the remnants of the Farallon Plate based on seismic tomography studies. The studies were conducted by Hans-Peter Bunge at Princeton University in 2000.

The Farallon Plate

In this animation from NASA's Scientific Visualization Studio, the Farallon Plate sinks beneath North American Plate and scrapes along bottom of continent for 1,500 kilometers before sinking again.

How a Nuclear Power Plant Works

This 88-second video from YouTube shows a labeled computer animation of how a nuclear power plant works to create energy.

How a Coal Power Station Works

This two-minute video tours a coal power station in Ontario to show how coal is used as an energy source. It includes animations to demonstrate machinery used at the plant.

World Oil Consumption - 3D Charts in Google Earth

This site, part of the Google Earth blog, provides 3-D graphs of the world's oil consumption by country, both raw use and per capita. The data comes from the CIA World Factbook.

Oil Formation and Trapping

This animation shows the successive stages in the formation of an oil reserve. In View 1, organic material settles, is buried, and is transformed by heat and pressure into oil. In View 2 an oil trap is formed: the area folds into an anticline, and oil migrates and accumulates in the anticline crest.
