June 01, 2009
Thanks to a global community effort, as of 2009, the United Nations officially designates June 8th as World Oceans Day. The goal is to highlight the many ways in which the ocean contributes to society and raise awareness of the current challenges faced by the international community in connection with the ocean.
The JPL Ocean Surface Topography (OST) outreach program joins with the world ocean community to advance public understanding of the ocean, including features such as ocean circulation and events like the El Niño Southern Oscillation (ENSO). ENSO encompasses the El Niño and La Niña phenomena, which occur in the Pacific Ocean basin.
The OST outreach team has produced a 4-inch by 6-inch card that shows changes in sea surface heights measured by the TOPEX/Poseidon satellite during 1997 and 1998. When viewed from varying angles, it shows the differences in sea surface height occurring during warmer, higher El Niño conditions, and colder, lower La Niña conditions.
In celebration of World Ocean Day, limited copies of the "Topex Lenticular Card" are available until June 30th, 2009. For more information, contact Annie Richardson at NASA's Jet Propulsion Laboratory.
We invite you to learn more about NASA's ocean satellite altimetry program and encourage you to celebrate World Ocean Day by participating in one of many events taking place this month around the world.Links:
