Seabed Mining (SBM) is an experimental industrial field which involves extracting submerged minerals and deposits from the sea floor. There are interests both for and against seabed mining, however, the science around the environmental impact of SBM is incomplete and unproven.
The underwater mining companies that are leading the field are Nautilus Minerals and Neptune Minerals. Both are currently pursuing exploration programs offshore to determine the viability of ...
> Natural gas and oil have been extracted from the seas for decades, but the ores and mineral deposits on the sea floor have attracted little interest. Yet as resource prices rise, so too does the appeal of ocean mining.
For years, the idea of prospecting for potentially rich deposits of minerals on the ocean floor was little more than a pipe dream. Extractive equipment was not sophisticated or cost-effective enough for harsh environments thousands of feet beneath the ocean's surface, and mining companies were busy exploring mineral deposits on land.
