Winter winds push cool dry air across the southeastern United States. Once the winds reach the Atlantic Ocean and Gulf of Mexico, they pick up moisture, and rotating convective cells form #cloudstreets. A larger version of this image is here: photos.app.goo.gl/fy4RGMyyTK54... #VIIRS

Summertime is very productive in the #RossSea along the Antarctic coast. This enhanced view shows the #phytoplankton blooming there on January 25, 2026. A larger version of the image showing more of the sea + McMurdo Sound & Ross Island is available here: drive.google.com/file/d/1xLOb... #Landsat8

The #Agulhas Current turbulently interacts with the continental shelf south of #CapeStFrancis leading to phytoplankton blooms (that color the ocean) & internal waves (that become visible by modifying surface smoothness). The full #Landsat8 scene is available here: photos.app.goo.gl/ps2geDxPWn4U...

Filamentous phytoplankton blooms fill the western #ArabianSea on January 19, 2026. The likely culprit: www.earthdata.nasa.gov/news/feature... A larger version of the entire northern Indian Ocean region is here: photos.app.goo.gl/GA3JmT9z79Af... #PACE_OCI

Smoke from fire just north of the River Rioni drifts westward from the Georgia coastline over the eastern Black Sea. A larger, higher-resolution version of the image is here: photos.app.goo.gl/qA1F2iGX8Z3C... #Landsat9

For no particular reason, here are some views of #Montenegro and #Albania collected by #Landsat8 today. You can get a full-resolution image here: photos.app.goo.gl/Skgk8Rvi5LLA... Happy 2026!

I'm saddened by this decision. During my years at Goddard, this library's technical reference books and journals -- publications that I would not have had easy access to elsewhere -- undergirded the work that I did. www.nytimes.com/2025/12/31/c...

Lots of butterflies on our Joe Pye weed. Mostly Tiger swallowtails but also a lone Monarch! 🦋 #nativeplants #monarchbutterfly #tigerswallowtail #joepyeweed

Summertime #cyanobacteria blooms persist in the southwestern #BalticSea, highlighting eddies and other flow lines in the region. Ship wakes cut through the surface slicks. Clusters of white dots are offshore wind farms. #Landsat8 Larger image available here: photos.app.goo.gl/DN9j9qQHtd9s...

After sweltering in the Washington DC suburban heat and humidity this morning, I felt like looking at something cooler for a bit. #Landsat8 #Greenland The full Landsat 8 scene is here: photos.app.goo.gl/gWwxFH49WruT...

This striking red invader of our garden was nearing adulthood until it met the bottom of my shoe. #LycormaDelicatula #EchinaceaPurpurea

At the end of May, Canadian wildfire smoke drifted eastward across the North Atlantic while Saharan dust drifted westward across the tropical Atlantic. Meanwhile, phytoplankton bloomed in the waters below. A 100-megapixel version of this image is here: photos.app.goo.gl/F8RHdMoKLzX6... #PACE_OCI

The American lawn: initially appealing in its uniformity, but ultimately boring, never mind being harmful to the environment. Native flora bring visual interest plus the rest of a fascinating ecosystem on their coattails. homegrownnationalpark.org/doug-tallamy/ photos.app.goo.gl/wVZpPmw7C7rB...

These are some of the flowers that were blooming in our yard on #EarthDay2025 .

The British Isles are seldom so cloud free, so I thought this recent #AquaMODIS view worth sharing, especially since the spring phytoplankton bloom had painted the ocean so nicely. John of Gaunt never got to see "This earth of majesty" from such a perspective. drive.google.com/file/d/18wpX...

Walking through the woods Fagus grandifolia Opens in softness

#LakePontchartrain, an estuary of the #GulfOfMexico, lies just north of #NewOrleans. It gains its color -- exaggerated here -- from suspended sediments, colored dissolved organic matter, phytoplankton, and various effluvia of human activity. #Landsat8 Larger image: drive.google.com/file/d/1hZw8...

There were very few duplicate signs at the "Hands off!" protest today. Most were homemade and expressed the bearer's personal issues -- sometimes rather humorously, sometimes rather NSFW -- with the current administration. P.S. This was not one of the funny ones.

The ocean partially visible here covers about a third of Earth's surface and it bears the name Pacific but it can often be less than peaceful as the pictured extratropical cyclones in the north suggest. (The commas missing above are in the image.) photos.app.goo.gl/VQZuoXbVsuHz... #PACE_OCI

In and around China's Yellow River delta the land is carved up into rectangles. Lots of them. Really, I wouldn't want to count them all. There are other shapes too, but it's mostly rectangles. There are still more on display in this much larger image. drive.google.com/file/d/1iCp1... #Landsat8

Happy π Day!

This cyclonic eddy in the Gulf of Oman aligns the phytoplankton near its surface making its otherwise invisible streamlines visible. #Landsat8 Larger image: photos.app.goo.gl/zNB67GJgqQyP...

Dear President Zelensky, As it is likely that our paths will never cross in person, I could not let this day go by without trying to reach you here. I come to you humbly as an American citizen who is thoroughly and completely embarrassed of our leaders. johnpavlovitz.substack.com/p/to-preside...

I stand with Ukraine. President Zelenskyy and the Ukrainian people should have the United States support instead of the embarrassing treatment given by the White House.

Could someone place an order for 100 more Jasmine Crocketts for overnight delivery to the Democratic Party thx in advance

Southern Africa: One flank green, the other blue Physics drives color. Ekman flow away from west coast = nutrient upwelling = many phytoplankton Warm water from tropics along east coast = few phytoplankton Rabbit hole: www.science.org/doi/10.1126/... Full size: photos.app.goo.gl/XLf3HMZDu27W...

I see people excited about DOGE. I don't disagree that there is waste in government spending. Congress sets the spending (Civics 101) and EVERYONE has a pet project in their home state. Giving a South African Billionaire access to the government checkbook is illegal. Congress needs to step up.

Summer brings intense #phytoplankton productivity to the #RossSea. These #CO2 eaters & #krill feeders highlight the swirls and ribbons of the local current field as do the #icebergs. Full #Landsat image: photos.app.goo.gl/GcP6B7AgRC3k... (graticule) photos.app.goo.gl/m67qABMMjbT3... (no graticule)

Born to immigrant parents on the Keweenaw Peninsula in 1909, my dad would have turned 116 today. Happy Birthday, Dad.

Despite all of its problems, Planet Earth is still a beautiful place to live. It's also the place we cannot live without. #PACE_OCI Larger version: photos.app.goo.gl/Ck4em1SyRvhe...

During my #NASA years, the #SouthAtlantic off #Patagonia always burst with color in the spring. Now, new sensors witness this #phytoplankton diversity. This #PACE_OCI image seems a good candidate for exploring that sensor's #hyperspectral chops. Larger image: photos.app.goo.gl/9mkYn5QNCBGz...

A lot of ship traffic passes through the #GulfOfSuez at the north end of the #RedSea. I wonder if any of the bright linear features shown here relate to that traffic. The full (30-meter) #Landsat scene is here: photos.app.goo.gl/WUQTRwmJ2rKF...

I experimented with social media for a few years on Twitter, but darkness is creeping in there, so I'm opting for bluer skies going forward. All posts before this one migrated from Twitter (sans their URL links to larger images). Hello world... again....

#Landsat9 flew overhead when a strong, katabatic wind blew out of the #Chugach Mountains on Oct. 18, 2024. Dust from the #CopperRiver valley was carried 230 km offshore before ducking under #GulfOfAlaska clouds. A full-sized version of this image is here:

Five orbits and thirty bands of OCI data from NASA's PACE mission captured this view of western North America & the Pacific Ocean on September 30th, 2024. The #phytoplankton are partying in the early fall sunshine. A larger version of the image is here:

One might think that it's hard to draw on water, but the ship wakes around #BlockIsland in the #northwestAtlantic belie that notion. They remain visible to #Landsat8 after a surprisingly long time. This scene was imaged on 3 July 2024. Larger version here:

It was bound to happen sooner or later. We are growing native plants to attract insects to our yard, but we did not want this little invader that got trapped in our birdbath. 😟 #SpottedLaternfly #LycormaDelicatula

Greetings to #OSM24 attendees gathered by the levees of the #MississippiRiver. The sediments, aerosols, CDOM, phytoplankton, & human infrastructure that many of you study all affected photons intercepted by #Landsat8 on January 31, 2024. Full scene here:

#Aquaculture, wind turbines, shipping, #phytoplankton, suspended sediment, colored dissolved organic matter, sea ice, turbulence: lots going on in the waters of #KoreaBay around the islands of China's Changhai County. The full-resolution #Landsat9 scene:

#Phytoplankton color the currents of #LancasterSound in #Nunavut on a mid-July day in 2023. A larger version of this #Landsat 9 image including phytoplankton blooms in nearby #PrinceRegentInlet can be found here.

A little Landsat-8-inspired whimsy. 🙃 The full scene is available here.

A little rearguard action this afternoon to slow the spread of this Maryland #invasive and to get some tasty treats. A whole family of deer were feasting at the prickly green and red buffet counter until I strode up. #RubusPhoenicolasius

Another day; another venue.
