NASA Visualizes The World’s Ocean Currents, Van Gogh-Style NASA Goddard Scientific Visualization Studio created an animation visualizing how water moves around the world. The video ‘Perpetual Ocean’ shows the surface current flow of oceans around the world, from July 2005 to November 2007. The white lines represent the currents, while the darker blue colors represent the “bathymetry” (ocean topography), according to Fast Co. Design. The mesmerizing video—which resembles Van Gogh’s ‘Starry Night’—was assembled through a combination of satellite, location and computational data generated by ECCO2 (Estimating the Circulation and Climate of the Ocean, Phase 2).

Sea Shepherd FR Oceana (Oceana) Qu'est-ce que le phytoplancton? - Phenomer Le phytoplancton, poumon de la planète Contrairement aux idées reçues, ce ne sont pas uniquement les forêts qui constituent le poumon de notre planète. A l’instar des plantes terrestres, le phytoplancton est constitué d'organismes photosynthétiques pourvus de chlorophylle grâce à laquelle il peut capter l’énergie solaire. La lumière du Soleil, le dioxyde de carbone et les sels minéraux dissous dans l’eau (principalement l’azote et le phosphate) suffisent au phytoplancton pour se développer et produire de l’oxygène, qui va diffuser à la surface des océans dans l’atmosphère. Le premier maillon de la chaîne alimentaire marine Grâce à la photosynthèse, le phytoplancton est capable de synthétiser de la matière organique (sucres) réutilisable par d’autres organismes comme le zooplancton. Une grande diversité de formes et de couleurs Le phytoplancton est composé de microalgues et de bactéries photosynthétiques appelées cyanobactéries. Les diatomées Les dinoflagellés

Plastic Breaks Down in Ocean, After All -- And Fast August 20, 2009 Though ocean-borne plastic trash has a reputation as an indestructible, immortal environmental villain, scientists announced yesterday that some plastics actually decompose rapidly in the ocean. And, the researchers say, that's not a good thing. The team's new study is the first to show that degrading plastics are leaching potentially toxic chemicals such as bisphenol A into the seas, possibly threatening ocean animals, and us. Scientists had previously thought plastics broke down only at very high temperatures and over hundreds of years. The researchers behind a new study, however, found that plastic breaks down at cooler temperatures than expected, and within a year of the trash hitting the water. The Japan-based team collected samples in waters from the U.S., Europe, India, Japan, and elsewhere, lead researcher Katsuhiko Saido, a chemist with the College of Pharmacy at Nihon University in Japan, said via email.

Denim from recycled ocean plastic Deep ocean wilderness destruction By Severin Carrell, 16 October 2005 The deep ocean is one of the world's last great wildernesses. But not for long. Two kilometres below the surface, scores of rare and exotic species are being wiped out at a dramatic rate. These unique species include the goblin shark which boasts a unicorn-like horn, prickly sharks with humped backs and glowing eyes, vast single-celled organisms as large as footballs and tripod fish that stand on their fins. In a letter passed to The Independent on Sunday, Britain's leading marine scientists have warned these species face extinction because of the global growth in deep-sea trawlers fishing for edible species such as the orange roughy, hoki and round-nosed grenadier. The damage is indiscriminate, they warned. Held down by rows of steel rollers weighing up to 200kg each, those nets are meanwhile devastating the ancient coral beds and sea mounts which are the home to the deep sea's marine life by scraping the sea bed clean.

Notre financement Contrairement à ce que laisse croire l’impact de nos actions, nous fonctionnons avec un budget très limité, que nous consacrons entièrement à nos programmes et nos travaux de recherche. BLOOM n’a jamais investi un euro pour lever des fonds. Nous savons que la pratique est courante et sans doute nécessaire pour changer d’échelle, mais nous avons un problème avec le principe d’utiliser les dons des particuliers pour lever des fonds et financer des campagnes d’appels à dons. Notre notoriété s’est établie sur la base de notre efficacité et nos soutiens financiers se font grâce au bouche à oreille et à la mobilisation des réseaux. Cela nous permet de vous garantir que 100% des dons sont alloués à nos actions. Année 2014 BLOOM devient association partenaire du 1% For The Planet, devenu l’une des plus importantes sources de financement des actions de protection de l’environnement dans le monde.

World's oceans in 'shocking' decline 20 June 2011Last updated at 13:24 By Richard Black Environment correspondent, BBC News Coral reefs are subject to "multiple stressors" that could destroy many within a human generation The oceans are in a worse state than previously suspected, according to an expert panel of scientists. In a new report, they warn that ocean life is "at high risk of entering a phase of extinction of marine species unprecedented in human history". They conclude that issues such as over-fishing, pollution and climate change are acting together in ways that have not previously been recognised. The impacts, they say, are already affecting humanity. The panel was convened by the International Programme on the State of the Ocean (IPSO), and brought together experts from different disciplines, including coral reef ecologists, toxicologists, and fisheries scientists. Its report will be formally released later this week. Fast changes This increases the amounts of these pollutants that are consumed by bottom-feeding fish.
