DEEP-SEA DILEMMA

The deep sea — usually defined as the realm below 200 metres — is a world of extremes. Temperatures near the sea bed in many places hover near 0 °C, there is next to no light, and pressures can exceed 1,000 bars, equivalent to having a couple of elephants standing on your big toe. But still life thrives. The deep sea contains a vast array of ecosystems that researchers have barely begun to study. The ocean floor holds vast deposits of ores containing sought-after metals.

WHY THE RUSH? - Seabed Mining in the Pacific Ocean

The Pacific Ocean is the scene of a new wild west. Companies and their investors, hungry for profits, are driving a speculative rush for seabed minerals. They are aided in this by donor government supported programs that promote the development of ‘responsible’ sea bed mining regulations. Globally, ocean ecosystems are under stress due to pollution, plastics, overfishing and climate change. The aspirations of sea bed mining companies will seriously compound these environmental stressors.
