The ocean is key to understanding climate change, sea level rise, ocean warming, tsunamis, and earthquakes. Because the ocean is difficult and costly to monitor, we lack fundamental data needed to adequately model, understand, and address these threats. Science Monitoring And Reliable Telecommunications (SMART) Cables is working to integrate sensors into undersea telecommunications cables. These sensors will share the power and communications infrastructure of millions of kilometers of undersea fiber optic cable, enabling seafloor-based global ocean observing at modest incremental costs. The Joint Task Force (JTF) leads the initiative to realize SMART cables. The JTF consists of three United Nations agencies, government agencies, research and academic institutions, and the private sector. Initial sensors include temperature, pressure, and seismic acceleration. These sensors will provide climate and ocean data and improve global tsunami and earthquake warning networks. In this seminar we first describe the SMART initiative and then focus on the SMART Atlantic CAM system connecting Lisbon (the Continent), Azores and Madeira in a 3700 km ring with SMART nodes along the cable, to be installed in 2026. The opportunities in early warning of seismic and tsunami events and climate and ocean circulation will be discussed.
