Topic: NASA’s Jason-2 Satellite
About the size of a small pickup truck, Sentinel-6 Michael Freilich will extend a nearly 30-year continuous dataset on sea level collected by an ongoing collaboration of U.S. and European satellites while enhancing weather forecasts and providing detailed information on large-scale ocean currents to support ship navigation near coastlines. ![]() The U.S.-European Sentinel-6 Michael Freilich satellite lifts off aboard a SpaceX Falcon 9 rocket from Vandenberg Air Force Base in central California on Nov. 21, 2020. NASA, EUMETSAT, and NOAA are collaborating on this mission. (NASA) «Read the rest of this article» Sections: Technology | No Comments
NASA announces Jason-2 Satellite to undertake new Science MissionWritten by Alan Buis
The Ocean Surface Topography Mission (OSTM)/Jason-2 satellite, a partnership among NASA, the National Oceanic and Atmospheric Administration (NOAA), the French Space Agency Centre National d’Etudes Spatiales (CNES) and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), marked its ninth year in orbit on June 20th, 2017. ![]() Illustration of the U.S./European Ocean Surface Topography Mission (OSTM)/Jason-2 satellite in orbit. OSTM/Jason-2 will soon take on an additional role to help improve maps of Earth’s sea floor. (NASA-JPL/Caltech) «Read the rest of this article» Sections: Technology | No Comments

NASA announces Jason-3 Satellite creates it’s first Global Ocean MapWritten by Alan Buis
The map was generated from the first 10 days of data collected once Jason-3 reached its operational orbit of 830 miles (1,336 kilometers) last month. It shows the state of the ongoing El Niño event that began early last year. After peaking in January, the high sea levels in the eastern Pacific are now beginning to shrink. ![]() The U.S./European Jason-3 satellite has produced its first map of sea surface height, which corresponds well to data from its predecessor, Jason-2. Higher-than-normal sea levels are red; lower-than-normal sea levels are blue. El Nino is visible as the red blob in the eastern equatorial Pacific.

NASA reports a strong, growing El Niño head to United StatesWritten by Alan Buis
El Niño 2015 has already created weather chaos around the world. Over the next few months, forecasters expect the United States to feel its impacts as well. The latest Jason-2 image bears a striking resemblance to one from December 1997, by Jason-2’s predecessor, the NASA/Centre National d’Etudes Spatiales (CNES) Topex/Poseidon mission, during the last large El Niño event. Both reflect the classic pattern of a fully developed El Niño. The images can be viewed at: ![]() The latest satellite image of Pacific sea surface heights from Jason-2 (left) differs slightly from one 18 years ago from Topex/Poseidon (right). In Dec. 1997, sea surface height was more intense and peaked in November. This year the area of high sea levels is less intense but considerably broader.

NASA reports Jason-3 satellite set to launch in JulyWritten by Alan Buis
Jason-3, a mission led by the National Oceanic and Atmospheric Administration that is currently scheduled to launch on July 22nd, is the latest in a series of U.S.-European satellite missions that have been measuring the height of the ocean surface for 23 years. «Read the rest of this article» Sections: Technology | No Comments
NASA study shows global warming not effecting Earth’s deep oceanWritten by Tony Phillips
Scientists at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, analyzed satellite and direct ocean temperature data from 2005 to 2013 and found the ocean abyss below 1.24 miles (1,995 meters) has not warmed measurably. Study coauthor Josh Willis of JPL said these findings do not throw suspicion on climate change itself. ![]() Deep sea creatures, like these anemones at a hydrothermal vent, are not yet feeling the heat from global climate change. Although the top half of the ocean continues to warm, the bottom half has not increased measurably in temperature in the last decade.

NASA’s Jason-2 satellite data points to possible El Niño in 2014Written by Tony Phillips
Lately, Jason-2 has seen something brewing in the Pacific—and it looks a lot like 1997. «Read the rest of this article» Sections: Technology | No Comments
NASA says ‘La Nada’ Climate Pattern Lingers in the Pacific
This neutral, or “La Nada” event, has stubbornly persisted for 16 months, since spring 2012. Models suggest this pattern will continue through the spring of 2014, according to the National Weather Service’s Climate Prediction Center. ![]() The latest image of sea surface heights in the Pacific Ocean from NASA’s Jason-2 satellite shows that the equatorial Pacific Ocean is now in its 16th month of being locked in what some call a neutral, or “La Nada” state.

NASA Scientific Visualization gives views of our Earth’s perpetually moving OceanWritten by Alan Buis
Developed by NASA’s Goddard Space Flight Center in Greenbelt, MD, the visualization is based on a synthesis of a numerical model with observational data. The model was created under a NASA project called Estimating the Circulation and Climate of the Ocean, or ECCO.
