===Trapped cores===
Large steep internal waves containing trapped, reverse-oscillating cores can also transport parcels of water shoreward.<ref name="Scotti A 2004">Scotti A, Pineda J (2004) Observation of very large and steep internal waves of elevation near the Massachusetts coast. Geophysical Research Letters 31:1–5</ref> These non-linear waves with trapped cores had previously been observed in the laboratory<ref>Manasseh R, Chin CY, Fernando HJ (1998) The transition from density-driven to wave-dominated isolated flows. Journal of Fluid Mechanics 361:253–274</ref> and predicted theoretically.<ref>Derzho OG, Grimshaw R (1997) Solitary waves with a vortex core in a shallow layer of stratified fluid. Physics of Fluids 9:3378–3385</ref> These waves propagate in environments characterized by high [[shear (fluid)|shear]] and [[turbulence]] and likely derive their energy from waves of depression interacting with a shoaling bottom further upstream.<ref name="Scotti A 2004"/> The conditions favorable to the generation of these waves are also likely to suspend sediment along the bottom as well as plankton and nutrients found along the benthos in deeper water.
