Array of Floats Collects One Millionth Data Profile
In the late nineties a group of scientists planned to maintain a network of 3,000 units, in ice-free areas, providing both real-time data and higher quality delayed mode data and analyses to underpin a new generation ocean and climate models. In 2007 the 3,000 float target was reached and the array has remained above 3,000 floats. The project is known as Argo. Argo floats are gathering profiles of temperature and salinity together with information on subsurface water movement at the rate of 1 profile approximately every 4 minutes, (360 profiles per day or 11,000 per month) and on 4 November 2012 the array passed the symbolic milestone of collecting its 1 millionth profile.
New York May Get Hurricane Barrier
Following super storm Sandy New York City may be looking at a surge-protection barrier. Sandy's relentless, wind-driven tides inundated seven subway tunnels under the East River, immersed electrical substations, and shut down the financial district and power south of 35th Street. It flooded parts of all five boroughs in the city of 8 million and killed more than 100 people in the United States, 42 in New York City. A 2009 engineering study by Mahwah, N.J. based HydroQual estimated that a barrier system involving massive floodgates at key points such as the East River and the Verrazano Narrows would reduce the flooded area of the New York metropolitan region by 25 percent…
Dr. Robert Ballard May Have Proof of Noah’s Flood
Dr. Robert Ballard the world-renowned underwater archaeologist may have proof of Noah’s biblical flood. He and his team have been exploring the Black Sea for evidence that Noah’s Flood may have been based on real events. In an interview for the Science Recorder Dr. Ballard explains. “Where I live in Connecticut was ice a mile above my house, all the way back to the North Pole, about 15 million kilometers, that’s a big ice cube,” Dr. Ballard explained “But then it started to melt. We’re talking about the floods of our living history.” Dr. Ballard and his team found ancient shoreline 400 feet below the surface proving that an historic flood took place in the Black Sea around approximately 5,000 BC.
British Scientists Look for Life in Extreme Environment
British scientists recently began an expedition to search for life in Lake Windermere, a stretch of water in Antarctica. Engineers and scientists set up camp on an ice sheet in West Antarctic. The team will use a sterile hot water drill to bore down to the subglacial Lake Ellsworth and retrieve samples of water and sediments that may have been isolated from the rest of the world for a million years. Scientists are interested to find if life can withstand such harsh conditions. If there were life to be found, it would have evolved in isolation for more than 100,000 years. The answers will further our understanding of life on Earth, and inform searches for life elsewhere in the solar system, such as in the ice-capped ocean of Jupiter's moon Europa.
Sound Levels Recorded at Wind Farm Site
Federal officials are studying variable impacts posed by the construction of the nation’s first offshore wind farm off Nantucket, Massachusetts. Studies include fish stocks, water and air quality, airplane and boat navigation, migrating birds and whales, and electric magnetic fields. One major component that needs further study is sound. Two scientists from Woods hole Oceanographic Institution (WHOI) is turning their attention to the impacts from the sound made by the wind farm. Sound travels faster and further through water than air. Many animals use sound to perceive their environment. Sounds made by humans influence animals, and loud sounds have a detrimental effect. In March WHOI biologists began recording a 25-square-mile area between Nantucket and Cape Cod.
New Study Shows That Two-Thirds of Ocean Species are Unknown
A new study published this week estimates that of the one million species that live in the ocean, as many as two-thirds are unknown. Experts working on an international database have say the world that exists beneath the oceans surface is largely unknown. There are an amazing amount of things, especially in the ocean, that we don’t know in terms of biodiversity,” says Pohle, who spent a decade taking part in an international Census of Marine Life, a decade-long project than concluded in 2010. It was only last year that scientists published research that estimated there are approximately 10 million distinct species on Earth, Pohle said. “It’s staggering to think that, as recently as 2011, we did not know how many species there are in the world by order of magnitude.
Seal Abundance in the Northeast Causes Concern for Scientists and Fishermen
Off the coast of Cape Cod Massachusetts and other local areas there has been a recent increase in seal populations. The local fisheries groups have raised concerns and scientists are rushing to document and understand the interactions between the seal populations and fisheries. These and other issues and challenges presented by seal populations have led to the creation of a new effort to improve our understanding of the ecological role of seals in the northeast United States. “This encompasses all issues: how they live, where they go, what they eat, their health and illnesses, and interactions with the world—including us—around them,” says Andrea Bogomolni, a Research Associate at the Woods Hole Oceanographic Institution (WHOI).
IMCA Publishes ROV Global Statistics
Remotely operated vehicle (ROV) statistics for 2011 have been published by the International Marine Contractors Association (IMCA) as an information note (IMCA R 05/12). The statistics, intended to record personnel and vehicle levels, are collected twice a year in February and August. The 2011 figures show that IMCA members had fewer ROV personnel at work in 2011 than in 2010, and that ROV personnel numbers reported in August 2011 exceeded those in February 2011 by about 25%. In February 2011 a total of 2,410 personnel was reported to be involved in worldwide ROV operations (2373 ROV superintendents, supervisors and pilot techs; and 37 other offshore ROV support personnel) compared with 3,018 in August 2011 (with the breakdown being 2923 and 95).
