I am grateful to the hon. Gentleman for giving me more credit than I am due. I was not claiming anything; I was merely quoting what a principal marine ecologist said. I would not wish the hon. Gentleman to think that was my theory. I would not want to claim credit for what Dr Patti Wickens said in Mining Weekly. I can only refer him to her if he wants to argue the case. I suspect he will get much further if he argues the toss with her rather than me. I will leave on the record what she said, however, and people can make their own minds up as to whether the hon. Gentleman or Dr Patti Wickens knows more about this subject. That is a judgment we will all have to make at some point.
The deep-sea bed is defined in the schedule as an
“area of the sea bed situated beyond the limits of national jurisdiction of the United Kingdom or any other State”.
The main marine mineral content of interest is manganese nodules, manganese crusts and seafloor massive sulphides. Two metallic mineral resources of the deep-sea floor incorporate dissolved metals from both continental and deep ocean sources. One of these is what my hon. Friend the Member for South East Cornwall—and, I
think, my hon. Friend the Member for Bury North (Mr Nuttall)—described as golf ball-sized polymetallic modules. I have heard them described as “golf-to-tennis” ball size, but I am not sure whether there is any mileage in arguing about the size, as we know what we are talking about here.
These nodules precipitate from sea water over millions of years on sediment that forms the surface of the deep ocean. It is understood that they require the undisturbed conditions which are found in areas of the deepest oceans. That serves to highlight again the environmental point that the undisturbed conditions are what is important. To clarify:
“Polymetallic massive sulphides are types of minerals discovered in the oceans in 1979 that were previously known only from deposits that have been mined on land since pre-classical times for copper, iron, zinc, silver and gold.”
Rather than get bogged down in all the science, which my hon. Friend the Member for Bury North covered in some detail, I will focus on some of the impacts of this proposed legislation and ask some questions, which I hope the Minister may be able to answer.
The history is important. The oceans had long been subject to a freedom of the seas doctrine, a principle dating back to the 17th century essentially limiting rights and jurisdiction over the oceans to a narrow belt of sea surrounding a nation’s coastline. The rest of the seas were proclaimed to be free to all. That seems to me to be a sensible doctrine. It has been challenged by some countries, however, which have tried to claim the rights to certain seas beyond what international agreement indicates.
