Freshwater is found in ponds, lakes, streams, rivers, bogs, and as groundwater (water beneath the Earth’s surface) in underwater aquifers. An [...]

In 2015, NASA will launch five airborne field campaigns to study how long range air pollution, warming ocean waters, and fires in Africa affect our climate. This effort into several incompletely understood Earth systems is part of NASA’s Earth Venture class projects. It is funded at a total cost of no more than $30 million [...]

In 2009, John Dabiri, a Caltech professor of aeronautics and bioengineering, and a colleague found that jellyfish can actually move water over distances greater than their body length just by swimming. This he said “was the first hint that animals could transport water over distances much longer than their body size.” The scientist next wondered [...]

Dead Zones Return

It is that time of year again. Dead zones formed between the spring and summer in both the Chesapeake Bay and the Gulf of Mexico. Scientists began studying this phenomenon in the 1970’s and are still trying to control it. According to NOAA, hypoxic zones are areas in the ocean of such low oxygen concentration [...]
