The Obama administration’s announcement that it may allow seismic studies potentially paving the way for offshore drilling along the East Coast is political posturing designed to distract voters concerned about high gasoline prices, oil industry leaders and Republican lawmakers said today.

The administration’s move “continues the president’s election-year political ploy of giving speeches and talking about drilling after having spent the first three years in office blocking, delaying and driving up the cost of producing energy in America,” said Rep. Doc Hastings, R-Wash. “The president is focused on trying to talk his way out of what he’s done, rather than taking real steps to boost American energy production.”

At issue is Interior Secretary Ken Salazar’s announcement in Norfolk, Va., this morning that the government is assessing the environmental effects of allowing seismic surveys along the mid- and south-Atlantic that could help locate hidden pockets of oil and gas. If ultimately approved, the studies by private geological research companies also could help guide decisions about where to place renewable energy projects off the coast.

The Interior Department is issuing a draft environmental impact statement that assesses the consequences of seismic research on marine life in the area. The Obama administration had planned to release a similar document in 2010, before the Gulf of Mexico oil spill.

If the draft environmental assessment is finalized after public comments and hearings, the Bureau of Ocean Energy Management could give companies permits to conduct the studies off the coasts of eight East Coast states.

Salazar said that if the geological research turned up promising results, that could open the door to offshore drilling in the area within five years, even though the administration currently has ruled out that kind of exploration before 2017. A government plan for selling offshore drilling leases from 2012 to 2017 does not include any auctions of Atlantic territory.

“If the information that is developed allows us to move forward in a quicker time frame, we can always come in with an amendment,” Salazar said. “We’re not prejudging that at this point in time. My view is … we need to develop information so we can make those wise decisions.”

Industry officials noted that under federal laws, it could take years for the government to revise the 2012-2017 leasing plan, even if federal officials decided to pursue Atlantic drilling.

Erik Milito, upstream director for the American Petroleum Institute, said the administration is repackaging old news and old plans to make it appear it is making real progress to encourage more domestic energy development.

“This is political rhetoric to make it appear the administration is doing something on gas prices, but in reality it is little more than an empty gesture,” Milito said.

Randall Luthi, the president of the National Ocean Industries Association, likened the administration’s announcement to giving the industry “a canoe with no oars, since there are no lease sales planned anywhere off the East Coast.”

If allowed to conduct seismic surveys, geological research firms would ultimately give the resulting information to the government and sell it to companies eager to analyze the data.

But Milito questioned whether seismic companies would pursue the work, given that some of their best customers — oil companies — wouldn’t be able to use it to plan offshore drilling for years, if at all.

“Without an Atlantic coast lease sale in their five-year plan, the administration’s wishful thinking on seismic research has no ultimate purpose,” Milito said. “The White House has banned lease sales in the Atlantic for at least the next five years, discouraging the investment and job creation, and ultimately production, which would make seismic exploration valuable.”

Still, at least six companies already have told the government they want to conduct seismic research along the East Coast.

“We have gotten significant expressions of interest from companies in contracting for these seismic surveys,” said Tommy Beaudreau, the director of the Bureau of Ocean Energy Management. “I am confident that, assuming the process continues on the track we anticipate, that there will be significant interest next year in conducting these surveys.”

Geological research uses seismic waves to map what lies underground or beneath the ocean floor. The shock waves — which some environmental advocates say may harm marine life — map the density of subterranean material and can gives clues about possible oil and gas.

Seismic studies also help identify geologic hazards and archaeological resources in the seabed — information useful in determining the placement of renewable energy infrastructure as well as oil and gas equipment.

The existing seismic surveys of the Atlantic coast are decades old, and in the years since, “there have been enormous technological advances,” Salazar noted.

“We do need to have seismic moving forward so we can really understand what the resource potential is,” Salazar added.

Amount of Coldest Antarctic Water Near Ocean Floor Decreasing for Decades

Scientists have found a large reduction in the amount of the coldest deep ocean water, called Antarctic Bottom Water, all around the Southern Ocean using data collected from 1980 to 2011. These findings, in a study now online, will likely stimulate new research on the causes of this change.

Two oceanographers from NOAA and the University of Washington find that Antarctic Bottom Water has been disappearing at an average rate of about eight million metric tons per second over the past few decades, equivalent to about fifty times the average flow of the Mississippi River or about a quarter of the flow of the Gulf Stream in the Florida Straits.

“Because of its high density, Antarctic Bottom Water fills most of the deep ocean basins around the world, but we found that the amount of this water has been decreasing at a surprisingly fast rate over the last few decades,” said lead author Sarah Purkey, graduate student at the School of Oceanography at the University of Washington in Seattle, Wash. “In every oceanographic survey repeated around the Southern Ocean since about the 1980s, Antarctic Bottom Water has been shrinking at a similar mean rate, giving us confidence that this surprisingly large contraction is robust.”

Antarctic Bottom Water is formed in a few distinct locations around Antarctica, where seawater is cooled by the overlying air and made saltier by ice formation. The dense water then sinks to the sea floor and spreads northward, filling most of the deep ocean around the world as it slowly mixes with warmer waters above it.

The world’s deep ocean currents play a critical role in transporting heat and carbon around the planet, thus regulating our climate.

While previous studies have shown that the bottom water has been warming and freshening over the past few decades, these new results suggest that significantly less of this bottom water has been formed during that time than in previous decades.

“We are not sure if the rate of bottom water reduction we have found is part of a long-term trend or a cycle,” said co-author Gregory C. Johnson, Ph.D., an oceanographer at NOAA’s Pacific Marine Environmental Laboratory in Seattle. “We need to continue to measure the full depth of the oceans, including these deep ocean waters, to assess the role and significance that these reported changes and others like them play in the Earth’s climate.”

Changes in the temperature, salinity, dissolved oxygen, and dissolved carbon dioxide of this prominent water mass have important ramifications for Earth’s climate, including contributions to sea level rise and the rate of Earth’s heat uptake.

“People often focus on fluctuations of currents in the North Atlantic Ocean as an indicator of climate change, but the Southern Ocean has undergone some very large changes over the past few decades and also plays a large role in shaping our climate,” said Johnson.

The data used in this study are highly accurate temperature data repeated at roughly 10-year intervals by an international program of repeated ship-based oceanographic surveys. Within the U.S., the collection of these data has been a collaborative effort of governmental laboratory and university scientists, funded primarily by NOAA and the National Science Foundation. However, much of the data used in this study were measured by international colleagues.

“Collection of these data involves 12-hour days, seven days a week, of painstaking, repetitive work at sea, often for weeks on end with no sight of land. We are grateful for the hard work of all those who helped in this effort,” said Purkey.
