Scientists suggest independent monitoring of deep-sea hydrocarbon industry

Deep-sea monitoring

2011-05-13

(Press-News.org) Writing in the scientific journal Nature, scientists have called for increased discussion of independent monitoring of deep-sea hydrocarbon industry activity with the aim of obtaining a better understanding of its ecological impact.

The hydrocarbon industry is increasingly searching for hydrocarbon resources at much greater depths and developing drilling technology to exploit them. However, drilling the seafloor at great depths is technically very challenging and carries with it poorly known risks.

"The Deepwater Horizon disaster in the Gulf of Mexico last year and the subsequent discovery of unexpected hydrocarbon accumulation at mid-water depths underscores the need for independent monitoring of the ecological effects in the deep sea," said Dr Henry Ruhl of the National oceanography Centre.

"In the past, the deep sea has been out of sight and all too often out of mind when it comes to the potentially damaging effects of human activities on the ecosystems that it supports," added Co-signatory Professor Monty Priede of the University of Aberdeen: 'If there is a problem on land, noise, fire, smoke and spills give signals that are obvious anyone in the vicinity, in the deep sea there are no human witnesses'

But the situation is changing. Advances in underwater monitoring equipment mean that images and data from the deep seafloor and the overlying water column can now be uploaded to the Internet in real time, and made publically available.

"Scientists need observations to help differentiate natural and human induced changes. Remote sensing could both facilitate sustainable resource use and provide an early warning of potential impacts," explained Dr Ruhl.

Through projects such as the Deep-ocean Environmental Long-term Observatory System (DELOS), scientists are already working with industry to help protect the marine environment. However, Dr Ruhl and Professor Priede argue independent monitoring is now necessary and that international bodies such as the European Commission and the United Nations could drive progress in this area. Their proposal for increased discussion has been supported by the General Assembly of the European Seas Observatory NETwork (ESONET).

Africa's sea turtles need passports for protection

2011-05-13

Satellite tracking of olive ridley sea turtles off the coast of Central Africa has revealed that existing protected areas may be inadequate to safeguard turtles from fishing nets, according to scientists with the University of California-Santa Cruz, the Wildlife Conservation Society, the University of Exeter, and others. Scientists involved in the study recommended the extension of an international marine park that spans the waters of Gabon and the Republic of Congo and better international cooperation to manage this threatened species. The study was published May 11 ...

No-Fault Divorce and Equitable Distribution of Property in New Jersey

2011-05-13

For the first time, in 2007, a new law allowed true no-fault divorce for couples with irreconcilable differences in New Jersey. Understanding the provisions of the state's no-fault divorce law and how marital property is divided among former spouses is essential for people undergoing or considering divorce in New Jersey. New Jersey No-Fault Divorce Under previous New Jersey law, a complaint for divorce had to state a specific ground for dissolving a marriage, such as extreme cruelty or separation. To obtain a divorce, one spouse had to allege that the other spouse ...

Dalhousie biologists interpret the language of sperm whales

2011-05-13

When they dive together, sperm whales make patterns of clicks to each other known as "codas". Recent findings suggest that, not only do different codas mean different things, but that whales can also tell which member of their community is speaking based on the sound properties of the codas. Just as we can tell our friends apart by the sounds of their voices and the way they pronounce their words, different sperm whales make the same pattern of clicks, but with different accents. Caribbean and Pacific whales have different repertoires of codas, like a regional dialect, ...

Bleak memories of childhood

2011-05-13

Every year, between 3000 and 3500 children are physically abused in Germany. Many more, some 12,000 to 13,000, suffer sexual abuse. These are the figures from official criminal statistics, but in fact a high proportion of unreported cases is assumed for both offenses. The latest edition of Deutsches Ärzteblatt International contains an article in which Winfried Häuser of the Technical University of Munich and his co-authors present the findings of their representative survey of a sample of the German population, conducted with the goal of quantifying the true dimensions ...

Repealing the Texas Driver Responsibility Program: A Good Idea?

2011-05-13

In 2003, Texas implemented the Texas Driver Responsibility Program. The Texas legislature thought the program would be an optimal way to combat problems like drunk-driving accidents, and budget shortfalls. However, critics say the program has been a failure and are now urging the legislature to repeal the program. What is the Texas Driver Responsibility Program? The Texas Driver Responsibility Program requires drivers who accumulate points on their driver's license for certain traffic citations or who are convicted of certain traffic offenses to pay a fine known ...

Salinity in Outer Banks wells traced to fossil seawater

2011-05-13

DURHAM, N.C. – Rising salinity in the primary source for desalinated tap water in North Carolina's Outer Banks has been traced to fossil seawater, not – as some have feared – to recent seawater intrusion. This means the saline groundwater in the Yorktown aquifer can remain a valuable source of desalination for decades to come, without Dare County communities having to switch to the much more costly alternative of desalinating seawater, says Duke University researcher Avner Vengosh. Vengosh, professor of geochemistry and water quality at Duke's Nicholas School of the ...

Economist studies how higher gas prices affect consumer behavior

2011-05-13

A dollar is a dollar is a dollar, so goes the economic theory of fungibility. But do people really act that way? In a new working paper, Brown University economist Justine Hastings and Jesse Shapiro of Chicago Booth School of Business find striking evidence that basic consumer choice behavior violates this bedrock theory. "Fungibility is an important assumption in many economic models, but we have a lot of laboratory evidence suggesting that people don't, in fact, treat a dollar as a dollar," said Hastings, associate professor of economics. "People instead try to manage ...

Treating HIV-infected people with antiretrovirals significantly reduces transmission to partners

2011-05-13

Men and women infected with HIV reduced the risk of transmitting the virus to their sexual partners by taking oral antiretroviral medicines when their immune systems were relatively healthy, according to findings from a large-scale clinical study sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. The clinical trial, known as HPTN 052, was slated to end in 2015 but the findings are being released early as the result of a scheduled interim review of the study data by an independent data and safety ...
