OS21E:
New Opportunities in Ocean and Earth Observing at the Seafloor Interface Posters


Submit an Abstract to this Session


Session ID#: 53492

Session Description:
Real-time information on a global scale about the ocean above and the earth below their shared interface can be obtained from sensors (e.g., temperature, pressure, and acceleration) deployed in conjunction with efficient data relays. One important example is  sensors embedded in submarine telecommunications cables. Such a deployment addresses two critical needs for science and society: 1) improved resolution and rapidity in global tsunami warning and seismic monitoring, and 2) sustained, cost-effective ocean circulation, sea level and climate data.
This session solicits abstracts on efficient interfacing and integration of sensors, improving sensor accuracy (e.g., drift free absolute pressure) and transfer functions, modeling studies to quantify the expected benefits of the improved sampling, and results from existing ocean-bottom systems.
