860-287450 - Tara Oceans Expeditions - May 2011. Tara with deployed plancton nets. On "station", the boat is drifting without engine or sails. Tara Oceans, a unique expedition: Tara Oceans is the very first attempt to make a global study of marine plankton, a form of sea life that includes organisms as small as viruses and bacterias, and as big as medusas. Our goal is to better understand planktonic ecosystems by exploring the countless species, learning about interactions among them and with their environment. Marine plankton is the only ecosystem that is almost continuous over the surface of the Earth. Studying plankton is like taking the pulse of our planet. Recently, scientists have discovered the great importance of plankton for the climate: populations of plankton are affected very rapidly by variations in climate. But in turn they can influence the climate by modifying the absorption of carbon. In a context of rapid physico-chemical changes, for example the acidification observed today in the world's oceans, it is urgent to understand and predict the evolution of these particular ecosystems. Finally, plankton is an astonishing way of going back in time ? a prime source of fossils. Over the eons, plankton has created several hundred meters of sediment on the ocean floors. This allows us to go back in time, to the first oceans on Earth, and better understand the history of our biosphere. More than 12 fields of research are involved in the project, which will bring together an international team of oceanographers, ecologists, biologists, geneticists, and physicists from prestigious laboratories headed by Eric Karsenti of the European Molecular Biology Laboratory.

857-94725 - Ester Hodari, age 22 years old, cooks dinner using the traditional three-rock cook stove with a fire in the middle. These cookstoves use a lot of fuel, firewood, and produce a lot of smoke. Ester told us that cooking with this type of stove made her eyes turn red and she often had a chest cough. Her children, ages 5, 2 and 3 months are often with her when she is cooking. Her sister-in-law, Shadya Jumanne, age 11, helps her cook as well. Not long ago Esterâs 3 month-old developed a cough, It kept getting worse and so they took her by motorcycle to the hospital at night. Ester started really worrying about this. After this Ester and her husband agreed that they needed to buy a clean cookstove and started saving. The girl helping Ester cook in some of the images is her sister-in-law Shadya Jumanne, age 11. Ester met Solar Sister entrepreneur Fatma Mziray when she married her husband and moved to this village, Mforo near Moshi, Tanzania. Ester said that Fatma is like a mother to her in the village. When Fatma showed Ester the new wood stove she saw that is used less wood and produced less smoke.
857-91065 - October 15, 2008 Snow Geese in flight, Port Susan Bay Preserve, Washington The marshes support abundant invertebrate life which, in turn, feed hundreds of thousands of shorebirds, including Wrangel Island snow geese. Port Susan Bay and adjacent Skagit Bay are important stops for migratory birds traveling along the Pacific Flyway, United States of America
