NICOP - Impact of Preferred Eddy Tracks on Tracers in Eastern Boundary Upwelling Systems
Abstract
This project proposes to investigate the impact of preferred mesoscale eddy tracks on physical and biogeochemical tracers in easte:This proposal on Oceanography is coming from a top university in Chile from a very motivated professor. this research intends to assess the impact of preferred mesoscale eddy pathwayson physical (temperature, salinity), biogeochemical (oxygen, carbon, nutrients) and other tracers in the Eastern Pacific off California and Chile. While previous work has suggested the existence of such pathways and associated them with the recently discovered banded pattern in the world ocean mesoscale circulation, their impact on physical/chemical properties has received little attention. The present effort will address the significance of eddy pathways for the transport and mixing ofbiologically and climatically relevant properties, with a broad range of applications of interest to the USNavy and to society at large.To this end, eddy-resolving models of the eastern North/South Pacific circulations available from previous research will be combined with offline models of Lagrangian particles and Eulerian passive tracer. Systematic tracking of mesoscale eddies will be used to decompose model and remotely sensed flows into several components including preferred eddy tracks and to reveal their contributions to advection and mixing of various tracers. Surface-drifting Lagrangian floats and a new coupled physical biogeochemical model of the eastern South Pacific will be developed to assess the impacts of preferred eddy tracks on the distributions of floating debris and biogeochemical properties, aspractical applications to the physical problem.B, Physical oceanography (e.g. mesoscale, mixing), numerical modeling and marine biology will contribute to environmental sensing of the marine battlespace in the Pacific, making it highly relevant to ONR.
