WHOI-led team locates Air France wreckage

2011-04-06
(Press-News.org) A search team led by the Woods Hole Oceanographic Institution (WHOI) has located the wreckage of Air France Flight 447 some 3,900 meters, or nearly 2.5 miles, below the surface of the Atlantic Ocean off Brazil's northeastern coast.

The team left the port of Suape, Brazil, aboard the vessel Alucia on March 22, arriving at the search site on March 25. After one week of searching, one of the mission's three autonomous underwater vehicles (AUVs), the REMUS 6000s, detected debris on the seafloor. A second vehicle was dispatched to the area for more detailed sonar mapping and photographic imaging. The images it brought back were relayed to BEA, French air safety investigation authority, which identified the wreckage as the Airbus A 330. All three REMUS vehicles are currently mapping the area to get a comprehensive view of the accident site.

Flight 447, a scheduled commercial flight from Rio de Jeneiro to Paris, crashed into the Atlantic Ocean on June 1, 2009, carrying 216 passengers and 12 crew members. WHOI led the search under the direction of the BEA, Bureau d'Enquêtes et d'Analyses.

The search mission was the fourth attempt to locate the aircraft. WHOI also participated in the third search effort. WHOI Senior Engineer Mike Purcell was the chief of sea search operations for the mission.

"We were confident from phase three [the last search attempt] that if we were searching in the right area, the vehicles' sonar could pick out the aircraft," said David Gallo, the project leader at WHOI.

That success came just one week into the latest mission "attests to the efficiency of the vehicles and the competence of this team," said Purcell.

Images included photos of the fuselage, engine and landing gear and a sonar image of the crash area. Investigators plan to examine the wreckage in detail and to continue to search for the plane's flight recorders

"We are honored to have been part of this effort to locate Air France Flight 447 and proud to be able to bring hope of resolution to the families of the victims," said Susan Avery, president and director of WHOI.

The search was targeted in an area of about 3,900 square miles (10,000 square kilometers), several hundred miles off northeastern Brazil.

The REMUS 6000s are designed and operated by WHOI. Two of the vehicles are owned by the Waitt Institute for Discovery; the third is owned and operated by Leibniz Institute for Marine Sciences IFM-GEOMAR of Germany. These vehicles are designed to operate in depths up to 6,000 meters (19,685 feet or 3.73 miles).

INFORMATION:

The Woods Hole Oceanographic Institution is a private, independent organization in Falmouth, Mass., dedicated to marine research, engineering, and higher education. Established in 1930 on a recommendation from the National Academy of Sciences, its primary mission is to understand the ocean and its interaction with the Earth as a whole, and to communicate a basic understanding of the ocean's role in the changing global environment.

Economics, physics are roadblocks for mass-scale algae biodiesel production, study finds

2011-04-06
MANHATTAN, Kan. -- Companies looking to engineer an eco-friendly diesel fuel have more red lights in their path. According to Kansas State University researchers, making petroleum diesel completely green would not only bend the laws of physics, it would cost too much green. "Fossil fuels are limited, and since we can't use more than what Earth offers, a lot of people are looking for alternative fuel sources like algae," said Peter Pfromm, professor of chemical engineering and member of a K-State interdisciplinary team that analyzed oil produced by algae as a source of ...

Force of acoustical waves tapped for metamaterials

Force of acoustical waves tapped for metamaterials
2011-04-06
Washington, D.C. (April 5, 2011) -- A very simple bench-top technique that uses the force of acoustical waves to create a variety of 3D structures will benefit the rapidly expanding field of metamaterials and their myriad applications—including "invisibility cloaks." Metamaterials are artificial materials that are engineered to have properties not found in nature. These materials usually gain their unusual properties—such as negative refraction that enables subwavelength focusing, negative bulk modulus, and band gaps—from structure rather than composition. By creating ...

Reduce Foodservice Utility and Maintenance Costs by Improving Water Quality

Reduce Foodservice Utility and Maintenance Costs by Improving Water Quality
2011-04-06
The Link Between Water & Utility Costs A foodservice location uses a significant amount of water, which can directly result in increased utility costs. Water bills and electricity bills are actually linked expenses. Water quality, specifically high levels of hardness and TDS, can cause inefficiencies in equipment that either heats or cools water. This image shows the heating element inside a boiler-based steam oven. As little as a 1/4" of scale buildup can decrease energy efficiency by nearly 40%. Imagine a typical combi oven that costs $1500 a year in electricity: ...

Inexpensive new instruments test building sealants under real-world conditions

2011-04-06
Washington, D.C. (April 5, 2011) -- Sealants, like weather stripping, are what separates the inside from the outside of a building, byproviding a barrier that prevents water from seeping in, for example, or heat from leaking out. The challenge, says research chemist Christopher White of the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland, is predicting when they will fail. Current methods test sealants statically, by placing them outdoors for long periods of time, to measure their resistance to the elements. The problem, says White, is ...

OSU chemist developing solution to nerve agent exposure
2011-04-06
Scientists are working to develop a new drug that will regenerate a critical enzyme in the human body that "ages" after a person is exposed to deadly chemical warfare agents. Christopher Hadad, Ph.D., professor of chemistry at The Ohio State University (OSU), is leveraging Ohio Supercomputer Center (OSC) resources to help develop a more effective antidote to lethal chemicals called organophosphorus (OP) nerve agents. "This project is a combination of synthetic and computational organic chemistry conducted through OSC at Ohio State, and biochemical studies conducted ...

Historian says history of nuclear power needs to be addressed

2011-04-06
CORVALLIS, Ore. – The long-standing conflicts over nuclear power and the risks of radiation exposure are nothing new – in fact, the debate over the damaged Fukushima Dai-Ichi plant in Japan are similar to arguments happening between scientists, governmental agencies and the public since 1945, according to an Oregon State University expert on the history of science. Historian Jacob Hamblin is the author of the 2008 book, "Poison in the Well: Radioactive Waste in the Oceans at the Dawn of the Nuclear Age." He specializes in the history of the Cold War era, with a particular ...

Fewer multiple births in states with insurance coverage for infertility

2011-04-06
Faced with the prospect of costly in vitro fertilization (IVF) but with no help from insurance coverage, some infertile couples feel pressure to transfer multiple embryos in an attempt to ensure that the IVF is a success. This can lead to higher rates of twin and triplet births and prematurity. But having insurance coverage could curtail the costs associated with these multiple births, according to a new study by researchers at Yale School of Medicine. Published in the current issue of Fertility and Sterility, the study found that the 15 states, including Connecticut, ...

Researchers identify the metabolic signaling pathway responsible for dyslipidemia

2011-04-06
(Boston) - Researchers from Boston University School of Medicine (BUSM), including Yu Li, PhD, and other colleagues, have demonstrated that a nutrient sensing pathway is involved in the disruption of cellular lipid homeostasis in obese and insulin resistant mice fed a diet high in fat and sucrose. This nutrient sensing pathway, which is described in the current on-line issue of Cell Metabolism, may also have implications for the health benefits of polyphenols containing foods against fatty liver, hyperlipidemia, and atherosclerosis associated with obesity and type 2 diabetes. Although ...
