✦ Synopsis
We develop the nonlinear Schrödinger method for fast and accurate computation of the velocity and acceleration fields under irregular ocean surface waves on finite depth, and apply it to laboratory and field data.

In this paper, we show that the spatial discretization of the nonlinear SchrSdinger equation leads to a Hamiltonian system, which can be simulated with symplectic numerical schemes. In particular, we apply two symplectic integrators to the nonlinear SchrSdinger equation, and we demonstrate that the
The modified nonlinear Schrijdinger equation of Dysthe [Proc. Roy. Sot. Land. Sex A, 369, 105-114 (1979)] is extended by relaxing the narrow bandwidth constraint to make it more suitable for application to a realistic ocean wave spectrum. The new equation limits the bandwidth of unstable wave number
