Joint Exploration of the Twilight Zone Ocean Network (JETZON) 1920 1272 Ocean Decade

Lead institution:

National Oceanography Centre – United Kingdom of Great Britain and Northern Ireland (UK)

JETZON focuses on the ocean region spanning 200m to 1000m depth. This contains the largest and least exploited fish stocks of the world’s oceans.

The Twilight Zone also plays a major role in global biogeochemical cycles and the sequestration of carbon dioxide. However, it is poorly understood. This ignorance is dangerous. The Twilight Zone is under multiple stresses, including fishing, deep-sea mining, climate change and proposed CO2 mitigation methods. With the majority of the Twilight Zone outside national boundaries, its size and inaccessibility means that its study is only possible through coordinated international action. This is the aim of JETZON.
