The need for an ocean monitoring system became apparent when the 1982/1983 El Niño, the strongest of the century, arrived undetected by the science community. In response, under the auspices of the Tropical Ocean Global Atmosphere program, scientists developed a collection of buoys to measure large-scale changes in the ocean and to help detect El Niño events as they develop.

Earth is known as the water planet. The global ocean covers more than 70% of Earth’s surface and contains 97% of the planet’s water. Less than 3% of water on Earth is stored in our lakes, rivers, glaciers, and icesheets. The ocean is a vast and critical reservoir that supports a diversity of life, helps regulate climate, provides a large ...
