Impacts of Mesoscale Eddy Structural Characteristics on Matched-Field Localization Uncertainty [PDF]

Sensors
Matched-field processing localizes underwater acoustic targets by measuring the degree of correlation between the acoustic field and replica fields. The intrusion of mesoscale eddies can induce sound speed mismatch in the matched-field process. Therefore,

Effects of Mesoscale Eddies on Southern Ocean Biogeochemistry. [PDF]

AGU Adv
AbstractThe Southern Ocean is rich in highly dynamic mesoscale eddies and substantially modulates global biogeochemical cycles. However, the overall surface and subsurface effects of eddies on the Southern Ocean biogeochemistry have not been quantified observationally at a large scale.
