The Joint Exploration of the Twilight Zone Ocean Network (JETZON)

Session ID#: 92092

Session Description:
It contains possibly the world's largest and least exploited fish stock and is responsible for recycling roughly four fifths of the organic material that enters the ocean's interior from productive surface waters globally each year. Yet, the ocean's Twilight Zone, the dimly lit region extending from a few hundred meters depth to 1000m, is still poorly understood from almost any perspective, whether physics, biochemistry or ecology. It may also be under threat as it has drawn attention due to an increasing demand for protein from a growing world population. We therefore risk exploitation before we understand the consequences. 

The current level of scientific activity focused on the Twilight Zone is unprecedented. A recent workshop alone brought together 13 international projects tackling aspects of the Twilight Zone's role and function, from viruses to fish. But as a community how can we obtain the greatest insight from ongoing work and how can we maintain focus on this potentially threatened environment? This town hall is to launch JETZON, an international group intended to act as coordinator and focal point. The meeting is open to all, to gauge the level of support in the scientific community and to refine JETZON's scope.
