| Abstract | The propagation of wavepackets in hydrodynamic free surface waves is governed by the nonlinear Schrodinger (NLS) equation to leading order. Higher (fourth) order perturbation theory typically leads to derivative NLS (DNLS) systems. `Dark' solitary waves, or wave trains with a local minimum in intensity relative to the far field, are computed for a special DNLS system. In contrast to the more well known NLS theory, dark solitons in DNLS systems can undergo abrupt change in character and become `bright' solitary waves on a continuous wave background. The implication and significance for such modes and their transformation will be studied from the perspectives of fluid dynamics as well as fiber optics.
