Sea spray aerosols occur naturally in the salty ocean air, and there’s much more in each of those tiny bursting bubbles than salt. They’re bursting with ocean life, from bacteria to phytoplankton--even viruses. Because sea spray aerosols seed clouds, they affect the climate. With support from the National Science Foundation (NSF), atmospheric chemist Kimberly Prather of the University of California, San Diego, and chemist Vicki Grassian of the University of Iowa are leading a team of scientists around the country who are working to better understand what role sea spray aerosols play in weather and climate change climate models. Part of the National Science Foundation Series “Science Nation.”

Sometimes rip currents are referred to as "undertow" or "rip tides." These ocean phenomena are narrow currents in the surf zone that move quickly away from shore. A typical rip current ranges from 50-100 feet wide, and can extend 100 yards or more offshore. It can reach speeds of over 5 miles per hour, which makes them dangerous and potentially deadly. Scientists are studying these currents with the hopes of better forecasting when and where they will form. Part of the "Danger Zone" series.
Jennifer Keyes began her NASA career as an intern and then a co-operative education student in 1999. In these programs, she worked on projects in atmospheric science, subsonic aerodynamics, and space exploration. Currently she is an aerospace engineer working as a systems analyst for the Office of Strategic Analysis, Communication, and Business Development at NASA Langley Research Center. In this role, Jennifer supports the senior leadership team as the lead for strategic governance and business development. Part of the "Women@NASA" series.
Sunspots have fascinated sky gazers through the ages. Now state-of-the art telescopes combined with the muscle of a supercomputer called “Bluefire” are allowing scientists to accurately model these mysterious structures, and unlock their secrets. Michael Knoelker and Matthias Rempel are solar scientists working at the High Altitude Observatory at the National Center for Atmospheric Research, known as NCAR, in Boulder, Colorado. With support from the National Science Foundation, their study of sunspots is critical to the understanding of how stars, like the sun, produce magnetic fields which is still one of the big unanswered questions in stellar astrophysics.
StormView™ is a software program that gauges how residents of hurricane-prone regions might react in the event of an imminent storm. It was developed by University of Miami professor Kenny Broad and a number of collaborators, and supported with funding from the National Science Foundation and the National Oceanic and Atmospheric Administration. It includes TV meteorologist broadcasts, newspaper stories, web stories, bulletins from NOAA and even interactions with neighbors. The StormView™ simulation provides a way for social scientists to collaborate with meteorologists to tailor more effective messages. Part of the National Science Foundation Series “Science Nation.”
Basking sharks are the second largest shark in the ocean, and NOAA scientists are using the latest technologies to study them. The scientists capture and tag the sharks in an effort to study their movements and preferred habitat. Part of "The Science Behind" series.
Five species of sea turtles are found in Florida’s waters and all are listed as threatened or endangered. Biologists off the Gulf Coast of Florida conduct in-water research and monitoring of the turtle species. They are collecting data on population trends and habitat utilization. Part of "The Science Behind" series.
At the Boulder Atmospheric Observatory tower, a team of scientists analyzes the isotope composition of water vapor and precipitation. The isotopes provide information about the source region of the water. The scientists can determine the extent to which rainwater comes directly from the ocean, evaporation, or plant transpiration.
What began as an undersea earthquake in the Indian Ocean ended as the most deadly tsunami in recorded history. Ten years later, scientists have a better understanding of these events, and coastlines are far better prepared for such a catastrophe, thanks in large part to the NOAA Center for Tsunami Research at Pacific Marine Environmental Laboratory. Part of the "Danger Zone" series.
Corals have been devastated by the past few years of intense ocean heat. However, coral scientists are getting closer to understanding what makes certain species of coral able to withstand high temperatures. Part of the "Coral Comeback" series.
Presents the principles of atmospheric dynamics. The Earth's atmosphere is a balance of gases and sunlight that allows for the possibility of life. It has a composition, structure, and life sustaining biological, geological, and chemical cycles in its lower reaches. Also, discusses how these atmospheric elements are being impacted by the unprecedented burning of fossil fuels.
For many years the Hubble Space Telescope has collected breathtaking images of the cosmos with remarkable clarity. Now, ground based telescopes are fighting back. They are combining the precision of several instruments and correcting for atmospheric shimmer. This program presents and explains the designs, uses, and outputs of different types of telescopes.
Different processes in nearby coastal oceans drive the ecosystems found in the Mediterranean climate zones. Atmospheric processes over the oceans influence seasonal rainfall patterns, while currents and ocean temperatures affect both local and regional climate conditions. Part of the "Mediterranean-Climate Ecosystems" series.
This animated short tells the story of Alfred Wegener, a German astronomer and atmospheric scientist, who came up with the idea that continents once formed a single landmass and had drifted apart. Continental drift explained why continents' shapes fit together like pieces of a puzzle and why distant continents had the same fossils. During Wegener’s time, the idea was met with hostility but after his death a large body of evidence showed that continents do indeed move. Today the theory of plate tectonics is a fundamental principle in geology.
The freezing and melting of water affects so much of the world. Ice crystals in thunderclouds create lightning. It is also powerful enough to crack boulders, float stones, and alter entire landscapes. Ice is a common substance, but it has some secrets and weird properties scientists have only just begun to understand. Part of the "It's Okay to Be Smart" series.
In the Pacific Northwest, people are stripping moss for the horticultural trade at such an alarming rate that it's now illegal to harvest it. Ecologist Nalini Nadkarni knows that moss is a key component to the eco-system of the region, which makes it important to study. But this globe-trotting scientist at The Evergreen State College needed a lot of help recording research data from some folks who have much more time than she does. Where better to find potential research assistants with lots of time on their hands than the nearby medium security Cedar Creek Corrections Center? With support from the National Science Foundation, Nadkarni’s idea has been so successful that now the prisoners are starting bee keeping and composting programs, in addition to growing and recording data about moss.
Carl Pennypacker at UC Berkeley runs Universe Quest, a summer program supported by the National Science Foundation to engage girls in science exploration. Some of the summer activities include: looking through a world-class telescope, going out to the beach to measure tides, and designing online games.
A food science professor discusses the chemistry and physics of food preparation and cooking. She also gives an overview of a food science laboratory and its equipment.
With help from the National Science Foundation, Cornell University’s Ornithology Lab is tracking bird breeding biology and the impact of climate change on bird populations. Some of the best information they are getting is from dedicated “citizen scientists” who provide critical data on what kinds of birds are nesting where, the number of eggs laid, and the number of chicks hatched.
Students learn what makes science different from other disciplines. They also explore the many exciting career opportunities in the science filed. Concepts and terminology discussed include: observing, solving problems, health, career, education, and sharing information.
