"Understanding the Planetary Life Support System: Next Generation Science in the Ocean Basins"
Driven by solar and internal geothermal energy, the complex processes interacting within the global ocean constitute the ‘flywheel’ of our planetary life-support system; it is the massive volume of the ocean that drives long-term weather and short-term climatic variations across the seas and onto the continents. Entirely new approaches to understanding the complexity, power, and vagaries of this ‘oceanic modulator’ are arising from the rapid implementation and use of submarine cabled networks that will provide unprecedented electrical power and bandwidth to thousands of increasingly sophisticated robot-sensor systems distributed throughout full-ocean environments.
Partly triggered by the advent of a growing number of these cabled research systems, oceanographers are poised to benefit from a host of emergent technologies largely driven by investment from communities external to ocean sciences. Important developments include: robotics, biotechnology, cloud computing, in situ chemical and genomic sensors, extraction of novel biochemical materials, digital imaging, nanotechnology, serious gaming, new visualization technologies, computational simulations and data assimilation, seismo-acoustic tomography, and universal access to the Internet. Far more powerful than any one of these emerging technologies will be the convergence of the ensemble when applied to understanding the innate complexity of our planetary life support system – the global ocean. As these rapidly evolving capabilities are integrated into sophisticated, remote, interactive operations throughout the ocean basins for decades, a new era of a pervasive human tele-presence throughout entire volumes of our, once ‘inaccessible’ global ocean will be realized. Such capabilities are required to meet the onset of immense environmental and societal challenges in the coming decades that can only be addressed through optimally informed international collaboration.
John Delaney is Professor of Oceanography and holds the Jerome M. Paros Endowed Chair in Sensor Networks at the University of Washington. Since 1997, he has directed development of the regional cabled ocean observatory in the northeast Pacific Ocean that evolved into the Regional Scale Nodes program within the National Science Foundation's Ocean Observatories Initiative. The construction phase of this observatory began in September 2009. This distributed, remote, sensor-robotic network will convert a sector of the Juan de Fuca tectonic plate and overlying ocean into an internationally accessible, interactive, real-time natural laboratory capable of reaching millions of users via the Internet. Delaney's personal research is focused on undersea volcanic and hydrothermal activity and has led to identification of exotic life forms that are sustained in such environments. As a scientist-educator, Delaney has served in leadership positions in international research programs, led a joint expedition with the American Museum of Natural History that was subject of a NOVA (PBS) and BBC documentary, and serve on NASA committees charged with defining missions to Europa, a moon of Jupiter suspected of harboring both a liquid ocean and submarine volcanoes. Professor Delaney is a 1964 Lehigh graduate and a member of our Board of Trustees.
