Scientific expectations

Develop and implement a new type of geophysical sensor that could lead to a radical improvement in imaging the Earth’s deep interior on a planetary scale. A robust, cost-effective and scalable technology to instrument the 70% of the Earth’s surface covered by deep oceans.

Societal impacts

This new ocean sampling hardware and software will enable the simultaneous collection of deep-sea data for a range of marine environmental disciplines. Its versatile design invites flexible co-hosting of other physical, chemical and biological sensors, targeted at issues of climate change, environmental degradation and ocean monitoring.
