My research will involve theoretical studies of problems in physical oceanography, with an emphasis on tides, tidal power, and surface waves. Studies of tides will include continued investigation of the reason for the extreme tidal range in Ungava Bay and the application of fluid dynamical principles to a better formulation of the representation of friction forces in coastal models. Studies of tidal power will build on my earlier results on the maximum power available from tidal currents and consider the reduction that occurs if only partial fences of turbines are used in channels. Studies of waves will include a new approach to rogue waves as "unexpected" waves, and a formulation of the back effect of breaking waves on an underlying current. This is important as the driving forces can be dominant in some situations.

我的研究将涉及物理海洋学问题的理论研究，重点是潮汐、潮汐能和表面波。潮汐研究将包括继续调查昂加瓦湾极端潮差的原因，以及应用流体动力学原理更好地表述沿海模型中的摩擦力。对潮汐能的研究将建立在我之前关于潮汐流可用最大功率的结果的基础上，并考虑如果在渠道中仅使用涡轮机的部分围栏时发生的功率减少。对波浪的研究将包括一种将异常波浪视为“意外”波浪的新方法，以及破碎波浪对底层水流的反向效应的公式。这很重要，因为在某些情况下驱动力可能占主导地位。
