NASA Satellites Watch Earth ‘Breathe’ in Awesome Time-Lapse Video

[ad_1]


A cool new time-lapse video of Earth reveals how our planet has modified during the last twenty years as NASA satellites constantly monitored the populations of vegetation on land and within the oceans.  


The video reveals Earth “breathing” repetitiously because the seasons change all through every year, with snow protection on the North and South Poles periodically rising and shrinking whereas inexperienced areas of vegetation do the identical. 

A NASA visualization shows 20 years of continuous satellite observations of plant life on land and at the ocean's surface from 1997 to 2017. Vegetation on land is represented on a scale from brown (low vegetation) to dark green (lots of vegetation). In the ocean, populations of phytoplankton are indicated on a scale from purple (low) to yellow (high).

Vegetation on land is represented on a scale from brown (low vegetation) to darkish inexperienced (a lot of vegetation). In the ocean, populations of phytoplankton are indicated on a scale from purple (low) to yellow (excessive).

“These are incredibly evocative visualizations of our living planet,” Gene Carl Feldman, an oceanographer at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, stated in an announcement. “That’s the Earth, that is it breathing every single day, changing with the seasons, responding to the sun, to the changing winds, ocean currents and temperatures.” 

The SeaWiFS satellite, launched in 1997, measures the amount of phytoplankton that blooms on Earth's ocean surfaces. Here, SeaWiFS data show how phytoplankton in the eastern equatorial Pacific Ocean responded to the transition between El Niño and La Niña conditions in 1998. Higher concentrations of phytoplankton are represented in purple and lower concentrations are pictured in yellow.

The visualization was created utilizing information from Earth-observing satellites like NASA’s Sea-viewing Wide Field-of-view Sensor (SeaWiFS) mission, which started ambading world ocean information in 1997, as effectively the area company’s Terra, Aqua and Suomi NPP climate satellites. 


Seeing how vegetation throughout the planet has modified during the last 20 years may also help scientists and researchers examine how ecosystems are responding to altering environmental circumstances, NASA officers stated within the badertion.


For instance, research have proven that rising sea floor temperatures have impeded progress of phytoplankton, which signifies that there are fewer organisms within the ocean to take away carbon dioxide, a greenhouse gasoline that’s the primary driver of local weather change.

“The space-based view of life allows scientists to monitor crop, forest and fisheries health around the globe. But the space agency’s scientists have also discovered long-term changes across continents and ocean basins,” NASA officers stated. “As NASA begins its third decade of global ocean and land measurements, these discoveries point to important questions about how ecosystems will respond to a changing climate and broad-scale changes in human interaction with the land.”
