Ireland’s Cutaway Peatlands

Peatlands have been mined in Ireland for centuries, but concern for climate is changing how they are managed.

We celebrated 50 years of the #Landsat satellite. 🥳

For half a decade, the mission has collected data on Earth’s forests, farms, urban areas, and freshwater, generating the longest continuous record of its kind.https://go.nasa.gov/3C6Tv7j

Scientists mapped the thickness of the lava flows from Mauna Loa with @nasa aircraft. 🌋🛩

The airborne data is overlaid on a #Landsat 8 image with topography from a digital elevation model.

Thicker lava flows are shown in yellow and thinner in teal.

#Landsat 9 captured this image of Mexico City, still showing the signs of an ancient network of canals and chinampas – small stationary “floating” garden beds – in the Valley of Mexico. https://go.nasa.gov/3j4Qf5W

Relic Chinampas in Mexico City

Many of the canals and floating fields used by ancient civilizations in the Valley of Mexico were lost as lakes were drained, but some examples of the watery fields remain in Xochimilco.

In a new study, scientists used #Landsat imagery from @nasa/@usgs to track shoreline changes and dramatic wetlands losses in Louisiana from 1984 to 2020.

The state lost nearly 21 square miles of important and vulnerable wetland ecosystems every year. https://go.nasa.gov/3UVZHFN

Larger Wheat Harvest in Ukraine Than Expected

A satellite-based analysis indicates that nearly 27 million tons of wheat were harvested from the country’s farms this year, but Ukraine won’t reap all of the benefits.

Earth has lost 561 square miles (1,453 square kilometers) of salt marshes in the past 20 years, a new @nasa study using #Landsat data shows.

Degrading marsh habitats releases carbon dioxide – a greenhouse gas – into the atmosphere. https://go.nasa.gov/3UEtIdg

NASA Scientists Map Global Salt Marsh Losses and Their Carbon Impact

Earth has lost 561 square miles of salt marshes over the past 20 years, according to a new NASA-led study of the first consistent global accounting of salt marsh locations and changes.

The world’s largest active volcano, Mauna Loa, is still erupting.

The @nasa/@USGS Landsat 9 satellite captured this image on Dec. 2. Infrared data from #Landsat’s OLI-2, which detects heat, is overlaid in red, indicating the presence of lava.

Since the best way to enjoy #Thanksgiving pie is a slice of BOTH apple and pumpkin... 👇

Illinois grows the most pumpkins of any U.S. state by acreage and weight of its harvest. This @nasa/@usgs #Landsat 8 image shows a major hub of pumpkin growing and processing. 🎃
