Eukaryotic cilia and flagella are chemo-mechanical oscillators capable of\ngenerating long-range coordinated motions known as metachronal waves. Pair\nsynchronization is a fundamental requirement for these collective dynamics, but\nit is generally not sufficient for collective phase-locking, chiefly due to the\neffect of long-range interactions. Here we explore experimentally and\nnumerically a minimal model for a ciliated surface; hydrodynamically coupled\noscillators rotating above a no-slip plane. Increasing their distance from the\nwall profoundly effects the global dynamics, due to variations in hydrodynamic\ninteraction range. The array undergoes a transition from a traveling wave to\neither a steady chevron pattern or one punctuated by periodic phase defects.\nWithin the transition between these regimes the system displays behavior\nreminiscent of chimera states.\n
