Student Airborne Researchers Explore California Air Quality 

During summer 2019, 28 undergraduate students are participating in an eight-week NASA airborne science field experience that will immerse them in the agency’s Earth Science research. NASA’s Student Airborne Research Program (SARP), embarking on its 11th year,  offers an opportunity for undergraduates majoring in sciences, mathematics and engineering to participate in all aspects of a

Satellites Find Biggest Seaweed Bloom in the World

An unprecedented belt of brown algae stretches from West Africa to the Gulf of Mexico—and it’s likely here to stay. Scientists at the University of South Florida in St. Petersburg’s College of Marine Science used NASA satellite observations to discover and document the largest bloom of macroalgae in the world, dubbed the Great Atlantic Sargassum

Looking For Freshwater In All the Snowy Places

Snowflakes that cover mountains or linger under tree canopies are a vital freshwater resource for over a billion people around the world. To help determine how much freshwater is stored in snow, a team of NASA-funded researchers is creating a computer-based tool that simulates the best way to detect snow and measure its water content

Drones Paired with Thermal Cameras Spot Moisture under Roof Membranes

By John Anderson, Strategic Business Development, FLIR Systems Inc. A new tool is making roof inspections safer, faster, and more efficient by reducing the need for dangerous treks up and across rooftops. Many roof inspectors are now investing in unmanned aerial vehicles (UAVs)—commonly known as drones—equipped with thermal and visible cameras so they can more

Old Ice and Snow Yields Tracer of Preindustrial Ozone

Using rare oxygen molecules trapped in air bubbles in old ice and snow, U.S. and French scientists have answered a long-standing question: How much have “bad” ozone levels increased since the start of the Industrial Revolution? “We’ve been able to track how much ozone there was in the ancient atmosphere,” said Rice University geochemist Laurence

Choosing the Right Antenna for GPR Investigations

By Jami Harmon, GSSI Antennas used with ground penetrating radar (GPR) come in different shapes and sizes. The largest antennas typically radiate the lower frequencies necessary to detect the deepest targets. The smallest antennas radiate the highest frequencies that provide the greatest resolution required to detect small, shallow targets. The “best” antenna for a job

Monitoring Network Assesses Ozone Layer Threats

On the heels of the first definitive signs of the ozone layer recovery in 2018, an international team of scientists discovered that production and emission of a banned, potent ozone-depleting chemical is on the rise again. A new research finding, published in Nature on May 23, locates the source region for about half of those

USGS, Scientists Test Drone-Based Stream Gauging

U.S. Geological Survey (USGS) and independent scientists gathered in Auburn, Maine, to evaluate the use of sensor-mounted unmanned aircraft systems (UAS), or drones, to gauge stream stage, velocity, bathymetry and discharge. The technology is being evaluated and modeled to determine whether it will support the fast, accurate and safe measurement of rivers, especially when they

360-Degree Camera Provides Ground-Based Imaging Following Weather Disasters

In the aftermath of natural disasters, capturing image data is a critical information resource for disaster management, supporting the response effort to deliver emergency infrastructures and supplies, risk assessment, damage assessment for cost estimation, structural analysis, and beyond. After Hurricane Michael in 2018 and a devastating tornado in Alabama in 2019, Site Tour 360 visited

Antarctica Detailed in 3D

Ice is a hot topic when it comes to understanding and monitoring how this fragile component of the Earth system is being affected by climate change. Scientists go to great lengths to study changes happening in the remote icy reaches of our planet–a subject that is being discussed in detail at the Living Planet Symposium
