The Governor of Papua New Guinea's Oro Province, Gary Juffa, has called on the government to conduct a scientific study to determine the threat deep sea mining could have on marine life.
This comes as the Government has renewed its commitment to the sea floor mining plans of the Canadian multi national Nautilus.
Mr Juffa told Parliament it's only fair a scientific study is carried out to determine whether tuna stocks will be affected.
He claims Nautilus's Solwara 1 project will affect the marine life.
Mr Juffa told parliament that there must be an independent investigation into the project site.
He says the government can then act upon the recommendation of the scientific findings.
