The National Science Foundation recently awarded Dr. Amit Tandon of the Physics Department $328,384 over three years to study the importance of submesoscale ocean processes to ocean productivity. The grant, titled "Collaborative Research: On the importance of Submesoscale processes for ocean productivity," was awarded by the Ocean Sciences Division at the NSF under ARRA. The project will support Professor Tandon, a graduate student, and a postdoctoral fellow, in addition to research opportunities for undergraduate students in the Upper Ocean Physics research Lab through August 2012.
The goal of the project is to examine the processes by which nutrients are advected into the euphotic surface layer of the ocean to support phytoplankton productivity in pelagic regions with shallow pcynoclines. The project is designed to test two competing hypotheses of whether the nutrients are upwelled by mesoscale eddies through eddy-pumping and eddy/wind interaction, or, whether the ageostrophic vertical motions supported by submesoscale (1-10 km scale, and O(1) Rossby number) frontal processes are largely responsible for the vertical nutrient þuxes. Dr. Tandon will be collaborating on this project with Dr. Amala Mahadevan of Boston University. Dr. Tandon's research focuses on applications of upper ocean processes to ecosystems and ocean mixing on shorter time scales, and to climate on long time scales. In his 10+ years at UMass Dartmouth, Dr. Tandon has brought in more than 1M dollars in external research grants, and was one of the two Chancellor's colloquium presenters for Spring 2009.
