Patrick Lynch, NASA's Earth Science News Team Mary Cleave left the NASA astronaut corps in the early 1990s to make a rare jump from human spaceflight to Earth science. She was going to work on an upcoming mission to measure gradations in ocean color "“ something she had actually seen from low-Earth orbit with her own eyes. From space, differing densities of phytoplankton and algae and floating bits of plant life reveal themselves as so many blues and greens. For Cleave, a former...

NASA satellite data can improve forecasts of dust storms in the American Southwest in ways that can benefit public health managers. Scientists announced the finding as a five-year NASA-funded project nears its conclusion. Led by investigators Stanley Morain of the University of New Mexico in Albuquerque, and William Sprigg of the University of Arizona in Tucson, scientists evaluated the influence of space-based observations on predictions of dust storms. Using NASA satellite data, forecasters...

What do puffins "“ colorful-billed birds looking like miniature penguins "“ have to do with the work we do at NASA? That would be a good question to ask Maria Frostic, an earth science film producer at Goddard. Better yet, catch her documentary, "Plight of the Puffins," on PBS next week to get the scoop. On a Fulbright scholarship, Maria took leave from Goddard for July and August 2007 and traveled to the Westman Islands of Iceland to make a documentary on the shrinking population...

Cool, wet conditions in the Northwest, frigid weather on the Plains, and record dry conditions in the Southeast, all signs that La Niña is in full swing. With winter gearing up, a moderate La Niña is hitting its peak. And we are just beginning to see the full effects of this oceanographic phenomenon, as La Niña episodes are typically strongest in January. A La Niña event occurs when cooler than normal sea...

NASA -- A new NASA Internet tool called "Giovanni" allows high school and college students and researchers to access and analyze satellite-derived ocean color data. Ocean color data provides students with information about ocean biology by looking at phytoplankton through changes in the color of the ocean surface. "Ocean color" refers primarily to the measurement of the green pigment called chlorophyll, which is contained in phytoplankton. Phytoplankton are free-floating plants that are the...
