3 Key Objectives: To better know planet Earth To promote the rational Ocean Exploration exploitation of marine resources To ensure sustainable development
4 Scientific Challenges To study the physical, chemical, biological and geological phenomena that occur in the ocean and its frontiers (atmosphere and Earth s interior).
5 The Azores Triple Junction The region harbours a large variety of vents and seamounts, active underwater volcanoes, chemosynthetic ecosystems, and extreme life forms (extremophyles)
6 Scientific Challenges Vents are very hard to study: Large depth (pressure is high) Highly corrosive environment Lack of optical visibility Navigation is a formidable challenge (lack of a GPS-like system) Submersibles: place human lifes at risk
7 Technical Challenges: Deep Sea Habitat Mapping near hydrothermal vents and in complex 3D environments Underwater cliffs, canyon walls, mass wasting walls, mid-ocean ridges, fracture zones, seamount flanks, continental margins, hydrothermal vent offices.
8 End products: Habitat maps (acoustics and vision)
9 Sea: the Ultimate Frontier Explore the Ocean Advanced technology is mandatory Future: Mobile Networked Sensor Systems (moored systems, robotic surface and underwater vehicles, gliders, submersibles, vessels, etc.)
