The focus of this discussion revolves around the testing and validation of integral model formulations and parameters concerning a subglacial plume ascending along a vertical ice face. This was accomplished by analyzing detailed fluid velocity and passive tracer measurements of a 3D printed line subglacial plume. Particle image velocimetry (PIV) and two-color laser-induced fluorescence (LIF) experiments were conducted along the trajectory of the plume. These experiments enabled the quantification of turbulent transport of momentum, mass, and heat in close proximity to the water-ice interface. Additionally, matching experiments were carried out on a non-melting, solid wall to provide a baseline for comparative analysis.
