Google Earth Leads Scientists to New Species in Mozambique

A British expedition of scientists to a mountainous forest called Mount Mabu in northern Mozambique has found that the area is home to hundreds of plant species, birds, butterflies and monkeys.

The 27-square-mile forest is being called a “Lost World” and a “hidden paradise,” filled to the brim with exotic plants, insects, and animals including three new species of Lepidoptera butterly and a new member of the poisonous Gaboon viper family of snakes.

A team of scientists led by the Royal Botanic Gardens in Kew also found in just a few weeks’ time that the lush forest was home to the blue duiker antelope, samango monkeys, elephant shrews, almost 200 different types of butterflies, and thousands of tropical plants, and say that at least a few additional new plant species and insects will probably be identified once all of the samples are analyzed.

“The phenomenal diversity is just mind-boggling: seeing how things are adapted to little niches, to me this is the incredible thing,” said Kew expedition leader Jonathan Timberlake, according to Mongabay. “Even today we cannot say we know all the world’s key areas for biodiversity—there are still new ones to discover.”

Kew scientist Julian Bayliss says that he found Mount Mabu, which had been previously unexplored due to unfriendly terrain and civil war, while researching possible conservation projects in the area using satellite imaging tool Google Earth, and unexpectedly noticed green, wooded areas in unexplored locales.

“Nobody knew about it,” Timberlake said to the Daily Mail. “The literature I’m aware of doesn’t mention the word Mabu anywhere. We have looked through the plant collections of Kew and elsewhere and we don’t see the name come up.”

Google Earth is not the only new technology that has recently become of use to scientists. Wired magazine reports that high-definition video is helping scientists study the forces that create volcanic eruptions.
A University of North Carolina seismologist Jonathan Lees and his colleagues found that examining high-definition video frame by frame and using seismic data let them view rapid movements of Guatemala’s Mt. Santiaguito’s dome that normally cannot be seen by the naked eye. “The dome is uplifting prior to the plume coming out,” said Lees. “We never knew this until we did this experiment.”

Scientists say that the new technique will aid them in their understanding of volcanic eruptions, which have been difficult to studying using only indirect measurements such as seismic recordings.

Punch Hole Clouds And Other Rarely Seen Cloud Formations

Punch Hole Clouds may appear as a circular or oval holes in a layer of supercooled clouds; sometimes they assume a form of a perfect circle and persist for quite a long time, drifting together with the cloud layer. One explanation seems to blame the air traffic (the jet contrail intersections) combined with a thermal inversion (a circular motion of a rising warm air).
It seems both rising and sinking air currents can create the same effect. Sometimes a very stable, uniform layer of high-altitude clouds can get "punched though" by a pocket of cold air, which sinks toward the ground - creating the circular hole formation.
NASA Terra satellite equipped with the Moderate Resolution Imaging Spectroradiometer (MODIS) has captured these images over Acadiana area in southern Louisiana - a splattering of round holes actually stretched over several states: Oklahoma, Arkansas, Louisiana, and Texas. Some were elongated, some appeared to have smaller clouds inside them.

"This strange phenomenon resulted from a combination of cold temperatures, air traffic, and perhaps unusual atmospheric stability. The cloud blanket on January 29 consisted of supercooled clouds. Supercooled clouds contain water droplets that remain liquid even though the temperature is well below freezing, and such clouds are not unusual. As aircraft from the Dallas-Fort Worth airport passed through these clouds, tiny particles in the exhaust came into contact with the supercooled water droplets, which froze instantly. The larger ice crystals fell out of the cloud deck, leaving behind the “holes,” while the tiniest ice particles in the center remained aloft." (source)
