One way to teach students about water quality and/or how scientists go about their work is to share articles with them. Here is a great article entitled "Study Maps Hidden Water Pollution in U.S. Coastal Areas". This research shows a great example of the use of both NASA satellite data and ground-based data. In this study, the researchers used U.S. topographic data as well as NASA climate models to "identify key inland regions that contribute groundwater and contaminants to the coast. They examined rainfall, evaporation rates and the amount of known surface runoff to...

Scientists rely on research, statistical models, and climate forecast models to help them determine upcoming natural events. Currently, scientists are have a difficult time deciding if and when the potential big El Niño event will happen. It will happen in 2017, but will it be the Summer or Fall? "Right now, many climate forecast models do predict the development of a full-fledged El Niño during this summer or fall. It’s likely that these models are acting on the much warmer-than-average waters near the coast of South America—the “Coastal El Niño" says Anthony Barson in his NOAA...

Concerns regarding the impact of global warming on vector-borne diseases have intensified interest in the relationship between atmospheric factors and dengue fever incidence. Global climate change poses the threat of serious social upheaval, population displacement, economic hardships, and environmental degradation. Changes in temperature, rainfall and relative humidity have potential to enhance vector development, reproductive and biting rates, shorten pathogen incubation period and encourage adult longevity. In addition, changes in wind direction, velocity and frequency will have an...

There will be a special Google hangout for GLOBE teachers and scientists on Feb 15 at 7pm (ET).  During this event, we will learn about the results of the research from several scientists who were onboard the research vessel, and will have a chance to ask questions about this work and results.  http://bit.ly/2lL4Kgd No registration required- open to any GLOBE teacher and/or scientist! Please share this! GLOBE Educator Webinar - Feb 15, 7pm ET Agenda below: Overview (~45 min program) Learn about an ongoing Earth science expedition with NASA scientists studying microscopic...

One of NASA's scientists, Dr. Stephanie Uz, has been working closely with the GLOBE ENSO Campaign throughout its beginning. She is an oceanographer who studies the response of ocean biology to physical forcing through remotely sensed satellite data, in situ measurements, model output and statistical reconstructions using proxies. Her research focuses on variability in global ocean color or chlorophyll concentrations, the pigment in microscopic phytoplankton, and the physical mechanisms causing those changes. Dr. Uz coordinates communication for the Plankton, Aerosol, Cloud, ocean Ecosystem...
