An uprecedented belt of brown algae stretches from West Africa to the Gulf of Mexico—and it’s likely here to stay. Scientists at the University of South Florida in St. Petersburg's College of Marine Science used NASA satellite observations to discover and document the largest bloom of macroalgae in the world, dubbed the Great Atlantic Sargassum Bel

There are several wildfires burning in Arizona as the wildfire season in the West begins in earnest.

Month: April 2013

Flooding in LaPlata

In early April 2013, severe flooding claimed more than 50 lives, and forced thousands from their homes in the Buenos Aires region, news sources said. Many of the casualties occurred in La Plata, situated about 60 kilometers (40 miles) southeast of Buenos Aires. Roughly 40 centimeters (16 inches) of rain fell on La Plata in a two-hour period April 2-3, Agence France-Presse reported.

Mike Ramsey

Mike Ramsey, a professor and vulcanologist at the University of Pittsburgh, is among 22 scientists being featured during April’s Earth Month for Know Your Earth 3.0, Local Connections, a partnership between 22 of NASA’s Earth-observing missions that nominated a scientist or engineer to be featured on NASA websites during April 2013. Ramsey uses data from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on board Terra.

Ice on the Caspian

The Caspian Sea isn’t really a sea but in fact a giant lake that spans roughly 1,000 kilometers (600 miles) from north to south. In the winter, ice often forms over the lake’s northernmost reaches, while the central and southern parts remain ice free. Temperatures are generally lower in the north, so you might guess that the ice owes its existence purely to the higher latitude. But the reality is more complex: From north to south, the Caspian Sea also exhibits differences in salinity and depth. Read more

Dust Storm in Libya

A dust storm blew out of Libya and across the Mediterranean Sea in late March 2013. Southwest of the coastal city of Banghazi (Benghazi), an especially thick dust plume spanned roughly 100 kilometers (60 miles), and the plume was thick enough to completely hide the ocean surface below. Read more
