马萨诸塞州海湾高频内波包的观测表明，它们是由落潮时海湾向海边缘海底岸外产生的背风波引起的。当潮汐转变为涨潮时，背风波传播到海湾中，非线性变陡，并发展成包。一个200 kHz的声学后向散射系统检测到的包的演变。在声学和密度剖面中观察到了大的倾覆事件。浮游生物的分布经历了强烈的垂直位移和混合与波包通道。
Observations in Massachusetts Bay of high-frequency internal wave packets indicate that they are caused by lee waves generated outside a submarine bank at the Bay's seaward margin during ebb tide. The lee waves propagate into the Bay as the tide turns to flood, steepen nonlinearly, and develop into the packet. A 200-kHz acoustic back-scattering system detected the evolution of the packets. Large overturning events were observed acoustically and in density profiles. Plankton distributions undergo strong vertical displacements and mixing associated with the wave packet passage.
