NASA Research Reveals Climate Warming Reduces Ocean Food Supply

The SESDA II News Team developed a NASA Headquarters Media Teleconference and press release issued on Dec. 6 that received significant press coverage around the world. The release — “NASA Research Reveals Climate Warming Reduces Ocean Food Supply” — focused on data from the SeaWiFS instrument correlating decline in ocean phytoplankton with warming climate over the past decade; the results were reported in the journal Nature. News coverage appeared in the Associated Press, Reuters, National Public Radio, and other media outlets.

State of the Universe 2007. New Images, Discoveries and Events

SESDA II staff member Peter Leonard wrote “The Most Powerful Explosions in the Universe…Gamma-ray burst discoveries with the SWIFT mission” with co-author Neil Gehrels, Principal Investigator for the SWIFT Gamma-ray observatory. The feature has been published on pages 154-162 in the book, State of the Universe 2007 edited by Martin Ratcliffe (Springer 2007, ISBN 0-387-34178-1). The book is now available from amazon.com. The feature outlines some dramatic new discoveries and the progress made in the past year in our understanding of the origin of some of these bursts. SWIFT carries three instruments: the Burst Alert Telescope (BAT), the X-Ray Telescope (XRT) and the UltraViolet/Optical Telescope (UVOT).

“Meteorological, environmental remote sensing and neural network analysis of the epidemiology of malaria transmission in Thailand”

This peer-reviewed paper by Richard Kiang, Farida Adimi, Valerii Soika, Joseph Nigro, Pratap Singhasivanon, Jeeraphat Sirichaisinthop, Somjai Leemingsawat, Chamnarn Apiwathnasorn, and Sornchai Looareesuwan was recently published in Geospatial Health, Vol. 1, 2006, pp. 71-84.

In many malarious regions malaria transmission roughly coincides with rainy seasons, which provide for more abundant larval habitats. In addition to precipitation, other meteorological and environmental factors may also influence malaria transmission. These factors can be remotely sensed using earth observing environmental satellites and estimated with seasonal climate forecasts. The use of remote sensing usage as an early warning tool for malaria epidemics have been broadly studied in recent years, especially for Africa, where the majority of the world’s malaria occurs.

The Brightest Explosions in the Universe

This article has been reprinted in Vol. 17 No. 1 of Scientific American Reports. It has been printed by Scientific American well over 1 million times.

This article by Neil Gehrels, Luigi Piro and SESDA II staff member Peter J. T. Leonard will be re-published in the March 2007 special issue of Scientific American on black holes. It was originally published in the December 2002 issue of Scientific American, and re-published in September 2004 in a Special issue entitled “The Secret Lives of Stars.”

“A picture like this could not have been drawn with any confidence a decade ago, because no one had yet figured out what causes gamma-ray bursts — flashes of high-energy radiation that light up the sky a couple of times a day. Now astronomers think of them as the ultimate stellar swan song. A black hole, created by the implosion of a giant star, sucks in debris and sprays out some of it. A series of shock waves emits radiation.”

Richard K. Kiang, Farida Adimi, Joseph D. Nigro, Ferdinand J. Laihad, Krongthong Thimasarn, Rakesh Rastogi, “In Search of Environmental Determinants for Malaria Transmissions in Indonesia.” With a population of 242 million, Indonesia is the fourth most populous nation in the world. It also has the third highest malaria endemicity in Southeast Asia after Myanmar and India. Approximately 40% of its population lives in malarious regions. Using the neural network method, an artificial intelligence technique, we have characterized the relationship between malaria transmission and environmental parameters. The results may also be used for early warning malaria epidemics and outbreaks.

E. W. Chiou, with second and third authors L.W. Thomason and W. P. Chu, published a paper in the August 15, 2006 issue of the American Meteorological Society’s Journal of Climate, entitled “Variability of Stratospheric Water Vapor Inferred from SAGE II, HALOE, and Boulder (Colorado) Balloon Measurements.”

Abstract of the article

NASA’s Hurricane Web Portal

SESDA II staff released the Portal on Sept. 25, 2006 as part of the GES DISC. The portal includes Current Conditions, an Image Gallery, and daily updates from spacecraft instruments including Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI) aboard the TRMM satellite and the Atmospheric Infrared Sounder (AIRS) aboard the Aqua satellite.

Featured on the portal is the Hurricane Viewer, an application for viewing a hurricane’s animated path that showing the varying levels of intensity and atmospheric information occurring at the time of the event. Over 35 sets of hurricane data are available.

The application requires Flash Player 8 or 9.
