There are a lot of shipwrecks in Sydney’s Homebush Bay, near the Olympic village, but none quite like the SS Ayrfield, also known as “The Floating Forest” for the lush mangrove vegetation that now covers its rusty hull.
Although 75% of the planet is a relatively unchanging ocean of blue, the remaining 25% of Earth's surface is a dynamic green. Data from the NASA/NOAA Suomi NPP satellite is able to detect these subtle differences in greenness.
The resources on this page highlight our ever-changing planet, using highly detailed vegetation index data from the satellite, developed by scientists at NOAA. The darkest green areas are the lushest in vegetation, while the pale colors are sparse in vegetation cover either due to snow, drought, rock, or urban areas.
Satellite data from April 2012 to April 2013 was used to generate these animations and images.

The first global map of vegetation from the recently launched Proba-V has been unveiled, demonstrating that the minisatellite is on track to continue a 15-year legacy of global vegetation monitoring from space.
Plants have long been reported to emerge from beneath Arctic glacier ice. One study from 1966 stated that “vigorous new moss shoots appear in places to be growing directly out of the underlying dead moss.” It concluded the new growth was a result of germination of either dormant or migrant spores on the “dead moss mats.”
That and all other publications since then, presumed that the emergent vegetation was dead. Now for the first time, researchers realized that at least part of that re-growth is coming from the Ice Age plants themselves. “This is an important distinction,” explains the lead scientist Dr. Catherine La Farge from University of Alberta.

To confirm their observations in the field, the team of scientists collected samples of these recently uncovered plants and grew them in the lab under careful monitoring. The results were unprecedented: a third of the plants re-grew! The discovery was reported in Proceeding of the National Academy of Sciences (PNAS).

After a year of satellite data collection, detailed maps of Earth's surface show the density of plant life. These maps track how vegetation changes can influence weather and ecology, as well as forecast drought, fire conditions, or malaria outbreaks.
