Scientists with the U.S. Geological Survey have created an
“Earth-as-Art” collection of brilliant images from space, as seen
from Landsat satellites.

Some pictures of Earth formations are reminiscent of actual
paintings; some include familiar objects; and some are like
abstract creations. Some show the actual colors of earth, sea and
sky, while some of the colors are created with filters to highlight
natural colors or even to capture light beyond the visible
spectrum.
These images remind me of the LIDAR images created by the
Washington Department of Natural Resources, which I called works of
art in a blog post nearly a year ago.
See Water Ways, Dec. 11, 2017. I included images of Puget Sound
among some satellite photos posted previously. See
Water Ways, Sept.11, 2017.
Landsat 8, an American observation satellite, was launched four
years ago. Since May of this year, the satellite has recorded more
than a million images.

As one might expect, satellite images of the same place vary
over time, considering that clouds, smoke, vegetation and
geological phenomena alter the appearance of the Earth’s surface.
You can see some differences in the pictures of Puget Sound on this
page. The first was taken on Aug. 27 and the second on Sept. 7. The
third picture, taken on Dec. 18, 2016, shows Mount Rainier in the
lower portion of the photo with Puget Sound in the upper part.

In some areas, the Landsat photos are so intriguing that they
have been compared to works of art. Staffers at Live Science, an
online magazine, chose 73 images to share with their readers. See
their full collection of “Artistic Views of Earth from Above” at
Live Science. I’ve picked some of my favorites and shown them
below.

If you are interested, you can go to the source of the Landsat
images, managed by the U.S. Geological Survey. I used a program
called EarthExplorer
to find the images of Puget Sound and Mount Rainier. Another search
engine, LandsatLook
Viewer, lets you zoom in on an area of North America or other
continents to obtain satellite images. A third approach is GloVis, with its multiple filters to
narrow your search.
The datasets are a collaboration between NASA, which developed
and launched the satellite, and the USGS, which developed the
ground systems for processing and sharing the data.
Following are four of the “artistic views” researched and
provided by Live Science, which today is offering 73 fascinating
photos of Hurricane Irma.

Putrid Sea: The various colors formed in a
cluster of lagoons on the Crimean Peninsula provides an interesting
painting, but the area has a reputation for foul odors caused by
the algae that gives the water its color. The proper name of the
area is Syvash, but some call it the Putrid Sea. The Syvash is part
of the disputed area controlled by Ukraine until Russia sent in
troops to annex the area in 2014.
Canyonlands // Photo:

Canyonlands: Yellows, browns and blue
characterize Canyonlands National Park in Utah, where the Green and
Colorado rivers come together. The rocky and dry area of the park
features unique geologic features, including steep canyons, eroded
arches and interesting rock formations as well as ancient Native
American rock paintings. The blue area in the photo is the peak of
Mount Waas. Author Edward Abbey called the Canyonlands “the most
weird, wonderful, magical place on Earth — there is nothing else
like it anywhere.”
Eye of Quebec // Photo:
USGS
Eye of Quebec: One of the Earth’s largest and
oldest known craters was formed by the impact of a three-mile-wide
meteor some 214 million years ago, experts say. The resulting
Canadian lake, Lake Manicouagan, has been called the Eye of Quebec.
The original crater was about 62 miles across, but erosion and
deposition of sediments has reduced that to about 45 miles today.
The island in the center of the lake is known as René-Levasseur
Island. I suspect the purple image is produced by selecting one
region of the light spectrum.
Green on Blue // Photo:
USGS
Green on blue: The swirls of green and blue in
the picture are largely phytoplankton floating in the Bering Sea,
the body of water that separates Alaska from Russia. The plankton
typically grow when there is an abundance of sun and nutrients,
often reaching their peak at the end of summer. This photo, taken
on Sept. 22, 2014, shows a few scattered white clouds dotting the
sky.
