    Title: The promise, potential, and pitfalls of globally-distributed subsurface internal wave and mixing measurements
    Abstract: Internal waves are responsible for the bulk of the diffusive mixing in the deep ocean, with implications for the rate of downward penetration of heat and carbon dioxide, as well as for the structure of the meridional overturning circulation. And yet global ocean models are far from being able to simulate the full internal wave spectrum--a necessary precursor to simulating how oceanic shear responds to different varieties of forcing and how energy cascades through internal waves to wave breaking, turbulence and mixing. As part of the "Global Internal Waves" initiative of the National Oceanographic Partnership Program, a global array of autonomous profiling floats is being deployed to measure shear, strain, and turbulent mixing, using a burst-sampling approach to separate internal waves from low-frequency motions. This project, SQUID (Sampling QUantitative Internal-wave Distributions), aims to improve the broad-scale characterization of internal wave climates, relate turbulent mixing levels to forcing by wind, tides, and topography, and evaluate the large-scale (low-mode) internal waves present in the latest generation of high-resolution global models. At the same time, SQUID is compiling and sharing past datasets from velocity profiling floats and working to transition observational results into model validation metrics and subgrid-scale mixing parameterizations. This talk presents the progress and findings of the SQUID project to date and invites collaboration on the future of autonomous shear and mixing measurements.
