Expendable floats for observations of 3D subsurface Lagrangian pathways in the upper water column
Abstract
Lagrangian observations of interior ocean pathways, subduction and uplift, have a long history, and have typically focused on largescale dynamics (eg RAFOS) that observe trajectories over basin-wide scales. Here we propose to collaborate with other funded teams to create an observational network capable of documenting interior ocean trajectories in polar and subpolar regions of complex bathymetry that are under-observed, and sensitive to longterm change. New tools are particularly important for observing trajectories that evolve at meso and smaller scales, and those that can yield statistical connections between the dynamics (vorticity, strain divergence) and the dispersion of discrete platforms. Our group proposes to build a fleet of forty expendable MINION floats for observing interior trajectories. The floats will be equipped with flexible acoustic receivers (uROAM) compatible with a range of source frequencies and sweeps for underwater localization. We will also conduct acoustic modeling to optimize source and receiver positional and ensure a successful experimental design.
