I’m delighted to share that our new paper is now out in @natclimate.nature.com! Our long-term, monthly Antarctic-wide dataset of surface meltwater shows that the East Antarctic Ice Sheet is becoming increasingly prone to surface meltwater ponding.

One of the most surprising (and exciting!) things about first getting into Carto/GIS work was discovering how accessible* NOAA, NWS, Landsat, Sentinel, etc. were. Like yeah you had to find and learn how to process them, but all this data, yours to discover and use.

WHY WE LOOK? Because the final image captured by the recently decommissioned Landsat 7 satellite shows how Las Vegas, "Sin City," has nearly doubled in size during the iconic spacecraft's 25-year lifespan. www.livescience.com/planet-earth...

Come along as we visit a #Landsat validation test site on the latest Eyes on Earth podcast episode. We’ll learn about why validation is important to maintaining Landsat’s gold standard, as well as hazards of the test site (ticks are one!). Listen: ow.ly/CEnh50W8muN

Remembering its quarter-century of faithful Earth observation, the USGS and NASA have announced the decommissioning of Landsat 7 from active service. Landsat 8 and Landsat 9 continue to collect images every day. Read more about Landsat 7: ow.ly/nz9k50W5CAQ

#Landsat 8 collected new images of these Canada fires on June 5, 2025. Image A shows a wildfire near the Petitot River in northeastern British Columbia. The Saskatchewan fire in image B is burning east of Mari Lake. More than 200 fires are currently active across Canada.

🌎🛰️After 25 years of Earth observation, the USGS bid farewell to #Landsat 7 on June 4, 2025. The legacy continues with Landsat 8 and 9, capturing planetary imagery to support global communities. 👉 ow.ly/ZTf150W4mp3

USGS, which operates the Landsat satellites, just announced that Landsat 7 was officially decommissioned today. Landsat 8 and 9 continue operations. www.usgs.gov/news/nationa...

#Landsat 9 captured imagery of an area in southern Switzerland that was devastated by a landslide on May 28th caused by partial glacier collapse. These natural color panchromatic-sharpened images show the area on May 13th, and again on May 29th.

Dust storms contribute to the accumulation of PM2.5 and PM10—particulate air pollution that is associated with respiratory and cardiovascular health risks. They can also spread viruses and fungal diseases and drastically reduce visibility.

Fallow farmland is the main source of human-caused dust storms in California’s Central Valley region, according to a new study using data from NASA and others. From 2008-2022, 88% of major human-caused dust events were associated with fallow land.

The Serra de Caldas is a monolithic oval-shaped plateau covered entirely by Cerrado, a biologically rich savanna and grassland ecosystem The Cerrado is the 2nd largest biome in S. America, home to thousands of plant, bird, reptile, and mammal species🧪

Volcán Poás, one of the most active in Costa Rica sustains a hot, ultra-acidic crater lake that shares similarities to Martian environments The Poás system may be hostile to most forms of life we are familiar with. But for a microbe adapted to acid, heat, and toxic metals, it’s paradise 🧪

Did you know there are 190 confirmed impact craters on Earth? #Landsat 8 captured an image of the Goyder impact structure in Australia—discovered in the 1990s—overlaid on a digital elevation model to give a sense of the topography. 🛰️ go.nasa.gov/3H6oPbP

This is near Vancouver Island in British Columbia, Canada. And see that blue glow? That’s a herring spawn! Every spring, thousands of Pacific herring congregate in shallow, vegetated coastal areas around this area to spawn, like in this #Landsat 8 image from April 27. (via NASA Earth)

Eruption of Kilauea as seen by Landsat-8/9 on May 16, 2025.

Scientists have discovered that trees near volcanoes can act as early warning systems before eruptions. As magma rises, it releases CO₂, which trees absorb—causing changes in leaf color and reflectance that satellites like NASA's Landsat 8 and ESA's Sentinel-2 can detect.

Landsat satellites captured imagery of active fires in north-central Saskatchewan, described by the Saskatchewan Public Safety Agency as the “busiest, most active fire level” this early in the season. Future #Landsat data will help assess landscape impacts.

Landsat images reveal the trails of ship traffic in major U.S. ports and harbors. Over 10 years of cloud-free imagery and the #Landsat panchromatic band were used to create these images.

The GOLD standard is the goal of the USGS EROS CalVal Center of Excellence #Landsat Cal/Val team. Experts focus on improving the accuracy, precision, calibration, & quality of data acquired by active Landsat missions publish their findings in reports: ow.ly/GH4J50VruLS

Landsat could use your support. The mission's 50+ year data continuity is at risk. If you believe contacting elected representatives does anything, now would be a good time to apply pressure. 🛰️📡

#OTD in 1984, #Landsat 5 was launched into space. Far exceeding its three-year design life, Landsat 5 set a #GuinnessWorldRecord for the “Longest-operating #EarthObservation satellite.” Its longevity ensured a continuous stream of data that kept the Landsat archive intact. 🛰️🌎

Iceberg A23a is drawing significant attention as it drifts toward South Georgia and the South Sandwich Islands. A #Landsat 9 image from Feb. 26 shows it roughly 50 nautical miles from the remote islands. Learn more about the journey of A23a here: ow.ly/Cz4950V7XVl

#A23a, the world's largest iceberg, began its journey in 1986 when it calved from Antarctica's Filchner Ice Shelf. It remained grounded for the next three decades, but in 2020, it detached and began drifting north. #Landsat #eochat #gischat
