Ridge formation modeled by advection of tracer particles placed on the simulated ice sheet. Blue and red histograms give the number of tracer particles on the ice sheet surface and deposited on the substrate, respectively using a 500 m bin size (resolution of PISM simulations). Particles are individually placed at the − 100 km flow line position and are advected by the flowing ice. Once a particle has been transported 50 m, a new particle is placed at the − 100 km position. The black histogram gives the number of deposited particles using a 50 m bin size and represents the same data in the red histogram.
