IWR Array Team
ObjectivesDeploy and utilize high-frequency in situ measurements to analyze the generation, propagation and dissipation of internal waves in the ocean using a combination of high vertical-resolution moorings and bottom mounted echo sounders to determine wave modal structures, speed, and direction of internal wave propagation. These internal-wave resolving (IWR) arrays consist of pressure-sensor-equipped inverted echo sounders (PIESs), current-sensor-equipped PIESs (CPIESs), and a densely instrumented, full-depth mooring.
An IWR array has been deployed during the SWOT satellite's initial calibration and validation phase. Our NOPP IWR Array complements NASA's SWOT Cal/Val objectives, with a particular focus on fast evolving internal waves.
Top Level Tasks
Deployment and Analysis: Deploy IWR arrays at various global locations and compare observed internal waves with model predictions, focusing on wave strength, variability, and vertical structure.
Wave Source Characterization: Evaluate the strength and sources of internal waves, including remote and locally generated fields, non-stationary internal tides, and high-frequency variance in the supertidal internal gravity wave spectrum.
Seasonal Variability: Assess the seasonal variability of internal wave propagation patterns and energy fluxes.
Wave Interaction and Mixing: Investigate the interaction of internal waves with ocean features such as eddies, fronts, and filaments, determining the implications for energy redistribution, mixing, and the fate of remotely generated low-mode internal waves.
