The ocean’s Twilight Zone is the dimly lit region extending from a few hundred metres depth to 1,000m. It is poorly understood from almost any perspective. However, it contains possibly the world’s largest and least exploited fish stock and recycles ~80% of the organic material that sinks out of the productive surface waters. There is a pressing need to understand the consequences of perturbing this critical ecosystem before we begin exploiting it to satisfy an increasing demand for resources from a growing world population.

The aim of JETZON is to provide the scientific understanding necessary to inform a sustainable approach to the management and conservation of the Twilight Zone ecosystem.
