Burn severity map showing nearly 1 million acres burned across Bolivia-Paraguay-Brazil border in August 2019. Landsat 8 dNBR analysis with four severity classes
Day 4/100: Maps for decisions 🔥
1M acres burned, Bolivia-Paraguay-Brazil
Landsat 8 dNBR analysis: 988K acres total, 638K acres continuous scar = 491K football fields

Not every map needs beauty. Some need accuracy + speed.

White icebergs and sea ice fill the lower left corner of the image while lines of white clouds and their dark shadows stretch towards the upper right. The rest of the image is filled with the blue, green, yellowish, and reddish swirls of the Ross Sea and the phytoplankton blooms it contains. The bloom colors have been enhanced to make them more visible. These data were collected by Landsat 8 / OLI on January 25, 2026 at 20:38 UTC.
Summertime is very productive in the #RossSea along the Antarctic coast. This enhanced view shows the #phytoplankton blooming there on January 25, 2026.

Green and turquoise swirls in the blue ocean south of green and tan Cape St. Francis, South Africa indicate the presence of phytoplankton blooms. Sun glint highlights both surface swells (tiny linear repeating patterns having mostly the same orientation) and internal waves (larger, more widely spaced criss-crossing patterns). Several large ships and their wakes also traverse the ocean pixels. This image was collected by Landsat 8 / OLI on January 24, 2026 at 8:11 UTC.
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).

We analyzed forest habitats in the #FUA of #Campobasso (Italy) using #Landsat8 satellite data 🛰
#NDMI resulted the strongest driver of vegetation greenness, far outweighing temperature💧
#NativeOak forests exhibited the highest greenness than coniferous plantations

Eddies and ribbons of cyanobacteria blooms paint the otherwise blue waters of the southwestern Baltic Sea. The land on the left (west) is Denmark; along the top right lies Sweden; the peninsula protruding into the bottom center belongs to Germany. This scene was collected by Landsat 8 on August 18, 2025 at 10:08 UTC.
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.

Landsat 8 image of Scoresby Sound in Greenland collected on July 6, 2025 at 13:39 UTC. White icecaps rest atop rugged red, green, and buff mountains while striated off-white glaciers flow towards the blue and cyan fjords of the sound. White icebergs speckle the blue water's surface. Brownish suspended sediments emerge from the coastline at a couple of the valley mouths.
After sweltering in the Washington DC suburban heat and humidity this morning, I felt like looking at something cooler for a bit.

Brown, tan, and green hues streak Lake Pontchartrain north of grayish New Orleans. The brown Mississippi River meanders through the bottom left quadrant of the scene. The connection to the Gulf of Mexico appears at the right side of the image. Lake Maurepas looks orangish-brown just to the left (west) of Lake Pontchartrain. Landsat 8 scene collected at 16:31 UTC on 22 March 2025
#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.

Landsat 8 montage of the coastal region near the mouth of China's Yellow River. The data making up the image were collected on February 24, 2025 at 2:42 UTC. Geometric shapes (mostly rectangles) tessellate the five panels of this image. Most of the shapes are green, blue, tan, or brown. Many are aquaculture ponds.
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.

Surface slicks of green phytoplankton (most likely Noctiluca scintillans) trace out the spiral arms of a cyclonic eddy in the Gulf of Oman to the northeast of Muscat. Ships and their wakes can be seen cutting through the surface slicks. The data for this image were collected by Landsat 8/OLI on March 8, 2025 at 06:28 UTC
This cyclonic eddy in the Gulf of Oman aligns the phytoplankton near its surface making its otherwise invisible streamlines visible.

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.

Intricate patterns in #HaLongBay make a good argument for higher resolution in coastal ocean remote sensing.

A reddish, bloom-like feature is visible in this #Landsat8 view of the #GulfOfCarpentaria on November 18, 2021. Anyone know what it is?
A larger version of the scene is here.
A week earlier, a storm passed through & mixed the water.
