Bottom trawling in European waters costs society up to €11bn a year, new study finds.
A first-of-its-kind study released today found that this cost is largely due to carbon dioxide emissions from disturbed sediments on the seafloor.
The study is the first to measure the full economic cost of bottom trawling in European waters - including the EU, UK, Norway and Iceland.

"Sulfate-reducing bacteria break down a large proportion of the organic carbon in oxygen-free zones of the Earth, and in the seabed in particular. Among these important microbes, the Desulfobacteraceae family of bacteria stands out because its members are able to break down a wide variety of compounds – including some that are poorly degradable – to their end product, carbon dioxide (CO2)".

A UN body that regulates deep international waters is preparing to elect its next leader,
a crucial position as it faces pressure to either ban, approve or place a moratorium on #seabed #mining.
The upcoming election comes as the Jamaica-based 
The drawn-out debate raises concerns that the authority could receive an application later this year seeking the first deep sea mining exploitation license without having rules or regulations in place.
The Metals Company, a Canadian-based mining company, is largely expected to be the first to apply for such a license.
Mining exploration has been ongoing in the 
which covers 1.7 million square miles (4.5 million square kilometers) between Hawaii and Mexico.
It is occurring at depths ranging from 13,000 to 19,000 feet (4,000 to 6,000 meters).
However, no exploitation licenses have been issued.
That could soon change given that some companies and countries are eager to mine the seabed and meet a surging demand for #precious #metals including cobalt, nickel and copper that are used in green technology.
Companies including BMW and Samsung SDI also have pledged not to use raw materials from deep-sea mining.
However, proponents of deep-sea mining say it is cheaper and has less of an impact than land mining.
Olav Myklebust, the authority's council president, told reporters Friday that there are still outstanding issues regarding a proposed regulatory framework, including inspection, compliance and enforcement and how best to determine payments related to exploitation.
He and secretary general Michael Lodge, who is seeking a third term, did not say if exploitation should start despite the absence of rules and regulations.

These powerful #airguns fire loud blasts of compressed air every 10 to 15 seconds, 24 hours a day. The sound waves produced penetrate deep into the #seabed and bounce back to the audio receivers. From the sound patterns detected, #companies can work out the most likely place to find oil and gas reserves under the ocean floor. The next step is exploratory #drilling.
