NASA Earth Expeditions: On the Iceberg Highway

If you remember the movie Titanic, this looks like a terrible place for a cruise. But to a captain with a lifetime of experience navigating around Greenland, it was a safe passage. And to scientist Ian Fenty of NASA’s Jet Propulsion Laboratory in Pasadena, California, it was a great place for research.

Notes from the Field Blog: SWESARR is Ready to Fly

Scientists and engineers are ready to fly a new instrument designed to measure the water contained within a snowpack.

Notes from the Field Blog: Ambushing the Aurora

Like the isbjørn (polar bears), we are ambush hunters. Our prey are atmospheric fountains, jets of gas being shot into space under the impact of the cusp aurora.

Earth Matters: 6 Trends to Know about Fire Season in the Western U.S.

Lately, it feels like we’re hearing about wildfires erupting in the western United States more often. But how have wildfire occurrences changed over the decades?

Earth Matters Blog: Responding to Hurricane Florence with NASA Data

When Hurricane Florence approached the Carolinas, the NASA Disasters Program began providing a suite of satellite data products to disaster responders, such as the Federal Emergency Management Agency (FEMA) and the National Guard. The goal was to provide the latest information for decision-making on everything from evacuations to supply routes to recovery estimates.

Earth Matters Blog: How Scientists are Tracking Florida’s Red Tides with Satellites and Smartphones

Put a sample of water from the Gulf of Mexico under a microscope, and you will often find cells of Karenia brevis swimming around. The microscopic algae—the species of phytoplankton responsible for Florida’s worst red tide outbreaks—produce brevetoxin, a compound that in high concentrations can kill wildlife and cause neurological, respiratory, and gastrointestinal issues for people.

Earth Matters Blog: The Trouble with Climate Feedbacks

A posthumous plea for more satellite observations of carbon arrived this week from astronaut and scientist Piers Sellers.

Earth Matters Blog: Remarkable Images of the Kilauea Eruption You May Have Missed

For more than two months, lava has been pouring from part of Hawaii’s Kilauea volcano, destroying homes and remaking the land surface. More data and imagery of the eruption is flowing in from satellites, drones, and ground-based sensors than Earth Observatory can cover, but here are a few striking images that we would be remiss not to share.

Notes from the Field Blog: Spruce Beetles in Alaska

This summer a team of scientists from NASA Goddard, American University, and the Forest Service are conducting joint field work within south-central Alaska to study the ongoing spruce beetle outbreak.

Glories—colorful, circular optical phenomenon caused by water droplets scattering light—are frequently spotted by scientists and crew with NASA’s Operation IceBridge mission

Earth Matters Blog: Mississippi’s Pulliam Prairie

This month we published a satellite image and map of the southern United States featuring the Black Belt Prairie—a crescent-shaped swath of land running through Mississippi and Alabama named for its characteristically dark, fertile soil.
