Dr. Knut Stamnes, Professor and Department Director of Physics and Engineering Physics at Stevens Institute of Technology, has been awarded a NASA grant for work on mathematical tools to monitor oceanic ecosystems via satellite. His proposal to "use and further develop advanced radiative transfer tools for polarized radiation in coupled atmosphere-surface systems" is funded as part of NASA's recently-created program in remote sensing theory for Earth Science.
The satellite-driven technology will allow scientists to view any part of the world in order to determine the health of the oceanic ecosystem. Dr. Stamnes' proposed algorithms represent a significant advance in remote sensing that will allow people who work with the ocean from fishermen to environmentalists to the military to track and respond to changes in a coastal or maritime system.
"This grant from NASA recognizes Dr. Stamnes' long-term efforts in developing technologies that support intelligent approaches to crises that result from natural and man-made changes in the environment. Remote sensing of the world's oceans is a critical step forward towards a more sophisticated understanding of global climate change and its effects," says Dr. Michael Bruno, Dean of the Charles V. Schaefer, Jr. School of Engineering and Science. "His award is consistent with Stevens wide-ranging program to increase observations and awareness of marine environments through research initiatives like the Center for Maritime Systems."
When visible and near-infrared light from the sun hits the ocean and the matter within it, some of it reflects and scatters back into the atmosphere, travelling to an orbiting satellite, where it is processed as data to be analyzed. Mathematical algorithms are used to interpret the colors of the backscattered light, employing the information available in all wavelengths (colors) in order to quantify the impact of the intervening atmosphere, and give scientists a clear i
