About the Cover:
The cover features two images of the Pacific Ocean produced using sea surface heights measurements taken by the U.S./French TOPEX/Poseidon satellite. The image on the left displays sea surface height relative to normal ocean conditions (shown in green) on November 10, 1997, and reveals a large volume of extra warm surface water (shown in white) that forms the core of El Nino. The image on the right from February 27, 1999, shows a low sea level or cold pool of water dominating the equatorial Pacific Ocean (shown in purple and blue), which is commonly referred to as La Nina. See Using TOPEX Satellite El Nino Altimetry Data to Introduce Thermal Expansion and Heat Capacity Concepts in Chemistry Courses by Harvey F. Blanck on pages 1635-1638.
