Post Shutdown, U.S. Tries to Salvage Antarctic Research

The government shutdown came to a close after 16 days. Its effect on Antarctic scientific research may last longer, though, as crucial research time was lost in an already brief summer research season.

“With the partial government shutdown now ended, the National Science Foundation (NSF) will restore the planned 2013-14 austral summer U. S. Antarctic Program (USAP) activities to the maximum extent possible,” NSF said in a statement posted on its website.

During the 16-day shutdown, the NSF directed all support elements of the Antarctic program to stand down toward “caretaker status.” That meant halting the flow of scientists and equipment to Antarctica for the short austral summer research season, which typically lasts four to five months, and evacuating some employees from U.S. field research stations. Many scientists who had spent years lining up funding and equipment to conduct research in Antarctica were left in limbo, unsure whether their work could go forward.

Scientists conduct a wide range of research in Antarctica, much of it focused on understanding the changing climate. The Antarctic ice sheet is a huge wild card in calculating the future rate of sea level rise, with the Antarctic peninsula warming at a rapid clip, and some glaciers melting rapidly. If the Antarctic ice sheet were to melt at a faster rate than scientists’ current estimate of 147 gigatonnes per year, sea level rise would be far more extensive and devastating to coastal communities worldwide. The Antarctic ice sheet holds far more water than Greenland, although that northern island is generally considered to be more sensitive to the warming climate.

In addition to keeping tabs on the ice sheet, scientists also make the arduous journey to Antarctica to check up on the health of iconic Antarctic species such as Adelie Penguins, which could see a drop in numbers due to habitat loss and other climate change-related impacts.

Lingering effects of the government shutdown also threaten to cause a gap in the lengthy, continuous datasets that scientists have painstakingly collected during the past several decades, whether it is data on Adelie population numbers, or ice cores that provide clues to Antarctica’s climate history. Introducing breaks in these records makes them less useful and reliable to scientists.

Putting U.S. Antarctic operations, which have an annual budget of about $350 million, on “caretaker status” also created ripple effect of logistical issues for Antarctic researchers from other nations with smaller research programs that rely on U.S. resources such as transport aircraft and other equipment.

The U.S. has long been one of the leaders of Antarctic research, operating three year-round research stations. While smaller research operations that rely on U.S. suffered, its absence opens the door for scientists from other countries doing major research in the region, such as Russia, China, and the U.K. to get ahead of their U.S. counterparts or even poach talented researchers from U.S. labs.

The potential absence of the U.S. from Antarctic research in 2013 struck many in the scientific community as worrisome and embarrassing. Ralph Cicerone, the president of the National Academy of Sciences, told Politico in an interview that this could be the first year in which the U.S. would be missing from the Antarctic field research season since a 1959 treaty directed that the continent be dedicated to international scientific research.

“A lot of major countries and developing countries, too, have a hand in doing research now in Antarctica. This coming year, the United States is going to be missing. It’s never happened before,” Cicerone said.

Though the two weeks the shutdown lasted might seem like a short period, it’s actually a large chunk of the brief season during which most Antarctic research takes place. As a result, NSF acknowledged that it is not clear whether all the planned research projects for the summer season can still go forward after being put on hold for so long.

“Over the coming days, NSF will work with the USAP support organizations and researchers to recover planned research and operations activities to the extent possible. It must be understood that due to seasonally dependent windows and logistic limitations, certain research and operations activities may be deferred,” NSF stated.
