A Return Home from ORACLES

Kirk Knobelspiesse (616) returned from several weeks in the field for the ORACLES (ObseRvations of Aerosols above CLouds and their intEractionS) Mission. Based this year on the African island of São Tomé, ORACLES studies smoke, created in sub-Saharan Africa, as it is advected over the South East Atlantic persistent marine stratocumulus cloud deck. Dr. Knobelspiesse helped deploy the Research Scanning Polarimeter (RSP) instrument on the NASA P-3 aircraft, and helps develop retrieval algorithms for this instrument while at home.

Del Castillo's Research Cited in Recent Forbes Article

A recent Forbes article described modeling research into how decomposing sea life matter affects ocean temperature. The authors used phytoplankton and colored detrital material (CDM) data collected by the Moderate Resolution Imaging Spectroradiometers installed on two NASA satellites that view the surface on an almost daily basis.

Earth Expeditions: Oh, The Places We’ll Go

Before I joined the science crew aboard the R/V Sally Ride and set sail for the middle of the Pacific Ocean for my first ever research cruise, I can honestly say I did not know what to expect.

The Ocean Ecology Laboratory conducts research on ocean ecosystems and the interactions between Earth's chemical cycles and life. The Laboratory also manages "ocean color" data from NASA satellite sensors. Sediment, dissolved chemicals, and marine microorganisms called phytoplankton affect the colors of sunlight reflected off the ocean, providing a way to monitor ocean ecosystems from orbit.

The Laboratory works to ensure the accuracy of ocean-color data and make it available to users across the world. Scientists use the data to study fundamental issues such as the global distribution of phytoplankton, the storage of carbon in the ocean, and the role of the oceans in climate change. Laboratory personnel also participate in research cruises in collaboration with other researchers funded by NASA and assist NASA Headquarters in developing future earth-observing missions.
