Direct Measurements of Momentum, Heat and Mass Fluxes from Ships & Surface Moorings: Methodology and Their Use in Marine Boundary Layer Studies

James Edson

Direct covariance measurements of surface fluxes from ocean-going platforms have been used in marine boundary layer studies for decades. More recently, we have made significant progress in computing these fluxes from buoys in autonomous operation for a year or more. Such buoys have been deployed in the CLIMODE, SPURS and IOVWST programs to study a variety of coupled ocean-atmosphere processes over annual cycles. The talk will begin by presenting results from a study that aims to optimize the motion correction algorithms required to compute the fluxes. The study relies on a comparison between a surface mooring and a nearby flux tower. The second part of the talk will provides examples of how the fluxes from both ships and buoys are being used for scientific investigations in the CLIMODE, SPURS, IOVWST and DYNAMO programs. T hese examples will focus on the behavior of the fluxes under high wind conditions and the role of surface heat and momentum fluxes in the dynamics of the MJO.
