Hydraulic platform used to tag the sharks safely. OCEARCH is a global non-profit organization specializing on research of Great White Sharks (Carcharodon carcharias) and other large predators, enabling leading researchers and institutions to generate previously unattainable data on the movement, biology and health of sharks to protect their future while enhancing public safety and education. OCEARCH is also a leader in open source research, sharing data in near real-time for free through the Global Shark Tracker, enabling researchers, students and the public to learn more about the Great White Sharks's habits and dynamics. Over 50 researchers from more than 20 institutions have collaborated with OCEARCH to date with over three dozen research papers in process or completed.

A NSF-sponsored workshop will be held in the coastal town of Maresias, São Paulo, Brazil, from the 4th to the 6th of February 2014, to discuss, plan and define the conceptual basis for developing an International Ocean Discovery Program (IODP) Drilling Proposal to investigate the Brazilian Equatorial Margin. b) The opening and expansion of the South Atlantic Ocean. The Brazilian Equatorial Margin (BEM) is a passive, stable margin at equatorial latitudes characterized by continuous sedimentary sequences divided among a series of basins. These basins contain a unique record of regional tectonic, biotic, and climatic events from the end of the early Cretaceous to present.

Statoil recently increased the estimates for their Campos Basin pre-salt O&G discoveries up to a substantial total of 1.24 billion barrels boe. Consequently Statoil has also increased its optimism for the geologically similar plays it has in Angola. Not only are the cross ocean plays geologically similar but they are also located along the same longitude. Both pre-salt geological formations off the Brazilian and West African coasts have their origins in common, something that goes back around 120 million years ago, when ancient Gondwana split into what is now known as South America and Africa. The pre-salt reservoirs on both sides of the Atlantic Ocean are expected to contain large quantities of light oil.

Two scientists, William Jones and Guilherme Castellane discovered two giant whirlpools in the Atlantic Ocean, off the coast of Guyana and Suriname. No can really explain exactly how these whirlpools were formed even though the area in question had previously been comprehensively mapped. The two funnels are approximately 400 kilometers in diameter. Until now whirlpools of this size were not known on Earth. The funnels may exert a strong influence on climate changes that have been registered during the recent years. “Funnels rotate clockwise. They are moving in the ocean like giant frisbees, two discs thrown into the air. Rotation occurs at a rate of one meter per second…

If the earlier searches for the debris had made a more intensive use of ultra-deepwater AUVs, finding the sunken fuselage, the black boxes and voice recorders may have taken considerably less than two years. However we must also consider that the total estimated search area was huge. The first idea of using submarines, just wasn´t enough with the extreme depth involved (3,900 meters). France had announced last February that it would begin the 4 phase of its search for the AF 447 debris, somewhere over 700 km from the north coast of Brazil, beyond the remote islands of Saint Peter and Saint Paul, a notorious shipwreck location. The new effort aimed to find the downed Airbus A330-200, which crashed on May 31 2009, killing all 228 passenger and crew members as it flew from Rio to Paris.
