Sustainability at center of British polar science strategy

The British Antarctic Survey (BAS) has set out its 10-year plan for polar exploration
The British Antarctic Survey (BAS) has set out its 10-year plan for polar exploration.

With research stations shifting to renewable energy and artificial intelligence mapping out fuel-efficient marine routes, the British Antarctic Survey is putting sustainability at the heart of its new 10-year plan.

"The main target for our strategy is really focused on because the polar regions are the regions on Earth which are changing most drastically," BAS director Jane Francis said, adding that these changes are "affecting the whole planet".

"What we're trying to do is plan the future of our science more now than we used to, because I think it's really so urgent that we can understand how our climate is changing. We need to support the relevant people in making good decisions about renewable energy, about how to save carbon, and how to live in better balance with our planet," she told AFP.

At the BAS headquarters in Cambridge, eastern England, AFP saw some of the cutting-edge technology used by scientists studying the polar regions.

Autonomous underwater vehicles are used to collect data from deep within the icy waters of the Southern Ocean, which encircles the Antarctic and acts as a carbon sink, absorbing heat and carbon from the atmosphere.

From the sky, drones and satellite technology help monitor and count animal populations in remote or inaccessible parts of the .

Ice core study

To gather information about in the past, scientists are drilling into ice sheets and glaciers to retrieve ice cores, some containing ice that is hundreds of thousands of years old.

The ice is cut inside a special cold room at the BAS labs where the temperature is kept at -25 degrees Celsius (-13 degrees Fahrenheit).

The trapped inside are extracted to measure the concentration of greenhouse gases, such as carbon dioxide and methane.

In the field, the BAS currently operates five research stations in the Antarctic, one of them only during the southern hemisphere summer.

The stations are serviced by a fleet of vehicles, ranging from snowmobiles to Sno-Cats and tractors, that make their way through the workshops at BAS headquarters before being deployed.

BAS scientists have been gathering evidence about climate change over the centuries, including ancient ice

The kit is modified to ensure it's "fit for purpose when it lands on the ice", for example by installing pre-heating systems that will help the engines start in freezing temperatures, BAS head of vehicles engineering Ben Norrish said.

Some snowmobiles are equipped with vehicle-tracking devices that have a distress button to request assistance from the station but also keep a record of refueling stops and other activity while out in the field.

It gives BAS "some kind of carbon accounting to see where we've gone during any given season," Norrish added.

Net-zero targets

Reducing carbon emissions is part of the BAS's wider sustainability strategy with the aim to be fully decarbonised across its operations by 2040, said Net Zero transition lead Nopi Exizidou.

"For our research stations, we are investing a lot in technology," Exizidou said, adding that BAS aims to decarbonize its polar stations within the next seven years.

The Bird Island station, off the northwest tip of South Georgia, west of the Falklands, is using a solar energy system and battery storage that is expected to reduce fuel use by 50 percent.

King Edward Point station, midway on South Georgia, has a hydropower plant, which meets 80 percent of energy demand in heating and electricity.

At Rothera, the largest British Antarctic research station located on Adelaide Island off the west coast of Antarctica, the new two-story energy-efficient Discovery Building is set to replace several old buildings.

BAS also has a team of engineers developing an and machine learning toolkit that will help plan marine routes and run research ships, such as the £200 million RRS Sir David Attenborough, more efficiently.

"They are developing tools that will sit alongside the master of the ship and will help him take more informed decisions on how to go from A to B," said Exizidou.

"We are developing, as we say, the Google maps of the Southern Ocean."

BAS director Francis said the changing technology that researchers will be using in the coming years is "really revolutionary now".

"We don't need to take the ship so far, we don't need to take the aircraft using fuel, we can send out our drones, we can send out our marine robots.

"And it means that we can collect data, so much more data, faster and do much better science."
