The results are in. The winning team in Earthzine’s second virtual poster session is a poster presented by the DEVELOP team at NASA’s Jet Propulsion Laboratory in Pasadena, California, on the presence of hazardous pollution in Los Angeles.

The winning DEVELOP team of Katrina Laygo, Asya Hollins and Caitlin Kontgis was chosen from 22 posters in the summer session based on comments and dialogue, as judged by a panel of scientists. The team spent its summer using satellite data to track small pollution particles in the Los Angeles metropolitan area. The JPL team concluded that downtown and South Central Los Angeles are exposed to high levels of these particles and are home to populations that are more at risk for suffering from detrimental health impacts.

“The JPL team made a professional, quality presentation,” said Gary Gibson, one of the judges and deputy director of the Science Directorate at NASA’s Langley Research Center in Hampton, Virginia. “They captured the viewers’ attention with well-chosen soundtracks and dramatic video clips, and they built on that by telling an engaging, well-narrated story. You could sense the dedication and excitement of the team.”

The three winning team members will share a prize totaling $450.

Three runners-up also were chosen by the judges, and will receive certificates and Earthzine T-shirts:

• 1st runner up: Hyperspectral Mapping of Invasive Species in the San Francisco South Bay Salt Ponds, Ames Research Center;

• 2nd runner up: Connecting Environmental Observations with Cholera Outbreaks in Bangladesh, Goddard Space Flight Center;

• 3rd runner up: Spaceborne Sensors Track Marine Debris Circulation in the Gulf of Mexico, Stennis Space Center.

Sponsored by NASA’s Science Mission Directorate Applied Sciences Program, DEVELOP mentors today’s young professionals in preparation for careers as tomorrow’s scientists and leaders. For more information about DEVELOP, including applications, visit develop.larc.nasa.gov.

Earthzine’s first DEVELOP virtual poster session was held in the spring of 2011.

Winner

Using NASA Earth Observations to Enhance Public Health Tracking of Particle Exposure and Extreme Heat in Los Angeles

Landsat Thematic Mapper Suitability Analysis Map of 2010 US Census Tract-Level Regions in the Los Angeles Metropolitan Area. The black circles depict the 13 EPA ground measurement stations with data that we assessed in developing a linear regression model. This was accomplished using NASA’s Multi-angle Imaging SpectroRadiometer (MISR) Level 1 Radiance Measurements as a predictor of ground-based particulate matter 2.5 measurements, based on MISR and EPA data from 2009.Will remote sensing play a greater role in addressing public health issues in the near future? DEVELOP students at the Jet Propulsion Laboratory analyze how NASA’s MISR data aboard the Terra satellite may assist in predicting ground-based air pollution in Los Angeles, California, and how Landsat 5’s Thematic Mapper can be used to map communities of vulnerability when linked to certain demographic factors.

Monitoring Agricultural Tillage Practices with NASA Hyperspectral Satellite Imagery

This image shows tillage classification derived from the Cellulose Absorption Index, which indicates crop residue. The accuracy of the classification distinguishing conventional tillage and conservation tillage was about 80%, and comparable to the accuracy of current monitoring methods. Ground data was obtained from Dr. Craig Daughtry, a research agronomist with the USDA-ARS Hydrology and Remote Sensing Laboratory in Beltsville, Maryland, from the same area shown within the bounds of the NASA Hyperion satellite swath above.How can NASA Earth observations help monitor the way farmers till their fields? In the wake of climate change and greenhouse gas levels increasing in the atmosphere, monitoring tilling practices has become increasingly important. Conventional tillage creates a carbon source, while conservation tillage creates a carbon sink. The need for an efficient and effective means of delineating fields prepared by conservation tillage calls for methodologies using remote sensing.

Implementing NASA Remote Sensing to Protect and Monitor our Waterways

Graphs showing a Material of Interest (MOI) classification overlay on a thermal profile of pumice rafts in two different locations. Red indicates a high concentration of pumice while black indicates the absence of pumice. The pumice raft in Argentina shows a negative temperature anomaly where the pumice is cooler than the surrounding water, whereas the raft in Tonga shows a positive temperature anomaly where the pumice is warmer than the surrounding water. The NASA and USGS Landsat 7 images show the location of the cross sections that were used to measure the temperature.A little-known danger lurks in the world’s oceans and waterways: Seemingly innocuous pumice rafts, a byproduct of volcanic eruptions, pose a hazard to maritime operations.
