How MPAs Safeguard the High Seas

The high seas begin 200 nautical miles from coastal shores, beyond the jurisdiction of any country. Their vast expanse and distance from shore pose challenges for exploration and knowledge gathering. However, scientific expeditions in recent years have revealed that these areas, which make up nearly two-thirds of the world’s ocean, harbor an incredible array of species that provide essential services for life on Earth.

262 Voyages Beneath the Sea: a global assessment of macro- and megafaunal biodiversity and research effort at deep-sea hydrothermal vents

For over 40 years, hydrothermal vents and the communities that thrive on them have been a source of profound discovery for deep-sea ecologists. These ecosystems are found throughout the world on active plate margins as well as other geologically active features. In addition to their ecologic interest, hydrothermal vent fields are comprised of metallic ores, sparking a nascent industry that aims to mine these metal-rich deposits for their mineral wealth.

High-seas fish biodiversity is slipping through the governance net

States at the United Nations have begun negotiating a new treaty to strengthen the legal regime for marine biodiversity in areas beyond national jurisdiction. Failure to ensure the full scope of fish biodiversity is covered could result in thousands of species continuing to slip through the cracks of a fragmented global ocean governance framework.
