Researchers have discovered a carbon 'conveyor belt' in the Arctic that could bind millions of tonnes of carbon dioxide in deep seas for millennia.
The discovery was made after a research vessel detected large amounts of particulate carbon — carbon stored in plant remains — was found in the Nansen Basin of the central Arctic.
Analysis revealed the body of water contained large amounts of particulate carbon at depths of up to two kilometres. The body comprises bottom water from the Barents Sea.
Bottom water is formed when sea ice develops in winter, and cold and heavy water sinks from the shallow coastal shelf, down the continental slope and into the deeps of the Arctic Basin.
“Based on our measurements, we calculated that through this water-mass transport, more than 2,000 metric tonnes of carbon flow into the Arctic deep sea every day, the equivalent of 8,500 metric tonnes of atmospheric CO2,” said Andreas Rogge, who led the research, which was published in Nature Geoscience.
That is equivalent to a 13.6 million tonne carbon flow each year — equal to Iceland’s total annual CO2 emissions.
The plume of carbon-rich water runs about 1,000 kilometres from the Barents Sea and Kara Sea shelf into the Arctic Basin.
That means the Barents Sea would appear to effectively remove roughly 30 per cent more carbon from the atmosphere than thought.
Model-based simulations suggest the outflow takes place in seasonal pulses, since in the Arctic’s coastal seas, the absorption of CO2 by phytoplankton only takes place in the summer.
Single-celled algae absorb carbon from the atmosphere on the ocean’s surface and sink when they die.
Once carbon bound in this manner reaches the deep water, it stays there until overturning currents churn the water back to the surface, which takes several thousand years in the Arctic.
But if the carbon is deposited in deep-sea sediments, it can be trapped there for millions of years, as only volcanic activity can release it.
This process, also known as the biological carbon pump, can remove carbon from the atmosphere for long periods, providing a sink in the Earth’s carbon cycle.
The process provides a food source for deep sea creatures such as sea stars, sponges and worms. What percentage of the carbon is actually absorbed by the ecosystem is something research will reveal.
The polar shelf seas harbour other largely unexplored regions where bottom water is formed and flows into the deep sea. As such, it can be assumed that the global influence of this mechanism as a carbon sink is increased.
“However, due to the ongoing global warming, less ice and therefore less bottom water is formed,” said Mr Rogge, an oceanographer at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research.
“At the same time, more light and nutrients are available for the phytoplankton, allowing more CO2 to be bound.
“Accordingly, it’s currently impossible to predict how this carbon sink will develop, and the identification of potential tipping points urgently calls for additional research.”

Young women have more “financial grit”, but fall behind on investing
In an October survey of young adults aged 16 to 25, Charles Schwab found young women are more driven to reach financial independence than young men (67 per cent versus. 58 per cent). They are more likely to take on extra work to make ends meet and see more value than men in creating a plan to achieve their financial goals. Yet, despite all these good ‘first’ measures, they are investing and saving less than young men – falling early into the financial gender gap.
While the women surveyed report spending 36 per cent less than men, they have far less savings than men ($1,267 versus $2,000) – a nearly 60 per cent difference.
In addition, twice as many young men as women say they would invest spare cash, and almost twice as many young men as women report having investment accounts (though most young adults do not invest at all).
“Despite their good intentions, young women start to fall behind their male counterparts in savings and investing early on in life,” said Carrie Schwab-Pomerantz, senior vice president, Charles Schwab. “They start off showing a strong financial planning mindset, but there is still room for further education when it comes to managing their day-to-day finances.”
Ms Schwab-Pomerantz says parents should be conveying the same messages to boys and girls about money, but should tailor those conversations based on the individual and gender.
"Our study shows that while boys are spending more than girls, they also are saving more. Have open and honest conversations with your daughters about the wage and savings gap," she said. "Teach kids about the importance of investing – especially girls, who as we see in this study, aren’t investing as much. Part of being financially prepared is learning to make the most of your money, and that means investing early and consistently."

HOW DO SIM CARD SCAMS WORK?
Sim swap frauds are a form of identity theft.
They involve criminals conning mobile phone operators into issuing them with replacement Sim cards, often by claiming their phone has been lost or stolen
They use the victim's personal details - obtained through criminal methods - to convince such companies of their identity.
The criminal can then access any online service that requires security codes to be sent to a user's mobile phone, such as banking services.

Fresh faces in UAE side
Khalifa Mubarak (24) An accomplished centre-back, the Al Nasr defender’s progress has been hampered in the past by injury. With not many options in central defence, he would bolster what can be a problem area.
Ali Salmeen (22) Has been superb at the heart of Al Wasl’s midfield these past two seasons, with the Dubai club flourishing under manager Rodolfo Arrubarrena. Would add workrate and composure to the centre of the park.
Mohammed Jamal (23) Enjoyed a stellar 2016/17 Arabian Gulf League campaign, proving integral to Al Jazira as the capital club sealed the championship for only a second time. A tenacious and disciplined central midfielder.
Khalfan Mubarak (22) One of the most exciting players in the UAE, the Al Jazira playmaker has been likened in style to Omar Abdulrahman. Has minimal international experience already, but there should be much more to come.
Jassim Yaqoub (20) Another incredibly exciting prospect, the Al Nasr winger is becoming a regular contributor at club level. Pacey, direct and with an eye for goal, he would provide the team’s attack an extra dimension.
