Abstract : The overall goal of this PRIMER program is to assess the feasibility of the operation of a synthetic aperture sonar on the continental shelf. To evaluate the performance of this sonar system, knowledge of the fluctuations of oceanic sound speed, primarily due to internal waves, is needed.

Internal waves are a ubiquitous and significant means of momentum and energy transport in the oceans, atmosphere, and astrophysical bodies. Here, we show that internal wave propagation in nonuniform density stratifications, which are prevalent throughout nature, has a direct mathematical analogy with the classical optical problem of a Fabry-Perot multiple-beam light interferometer. We rigorously establish this correspondence, and furthermore provide the first experimental demonstration of an internal wave interferometer, based on the theory of resonant transmission of internal waves.

The interaction of internal waves and surface waves in water is explored in the regions where the effects of the interaction are small. Explicit solutions for an arbitrary internal wave are given for various kinds of boundary conditions, with a detailed discussion of the conditions under which they are valid. The connection of the solutions with the conservation equations is made explicit, and the modifications produced by viscous damping are outlined.

The relation between internal wave variability and larger and smaller scales of motion is investigated, using the IWEX data set. To investigate the role of internal waves in the vertical diffusion of large scale momentum, the time variability of the vertical flux of horizontal internal wave momentum (estimated from temperature and current data) is compared to that of the mean vertical shear. It is found that internal waves cannot cause a vertical viscosity as large as proposed by Müller (1976), but that the data are too noisy to detect a possible wave‐induced viscosity in absolute value of the order of 10−2 m2 s−1 or less. Similarities in the time behavior of the total internal wave energy and that of the square mean vertical shear suggest that some kind of dynamical coupling exists between internal waves and larger scale flows. There is some evidence that the level of temperature finestructure activity also varies in a related way. An analysis of CTD station data taken during Mode demonstrates the mappability of the finestructure activity, and again suggests a relation with the geostrophic eddy flow.

The goal of this research is to understand internal waves in the ocean, and their relationship to other oceanographic phenomena, especially the dissipation of energy. Work carried out included a study of the energetics of the coastalregion tidally-generated internal waves we call "solibores," and two topics in the formal theory of the Hamiltonian description of ocean dynamics.

We are presently engaged in the direct numerical calculation of the interactions among a set of random internal gravity waves. The calculations are in 2‐D using a pseudo‐spectral code of 128×128 spectral components. They are initialized using the Garrett‐Munk spectrum. The effect of nonlinearity will be assessed by changing the initial total energy level. Preliminary results will be presented for the spectral transfer and temporal energy balances.

The ocean is a stratified medium and thus filled with internal gravity waves. Even though the statistics of these fluctuations are fairly well known, these waves fluctuate randomly and hence represent true uncertainty. When an acoustic prediction is needed for an ocean region, knowledge of the background sound speed profile is an additional uncertainty. A processing module is developed that takes profile estimates as input and uses numerically simulated linear internal wave displacements to create two-dimensional range-dependent sound speed fields. These fields are available for use in acoustic modeling and target estimation studies. Field realizations were obtained for four ocean regions. These examples illustrate variability induced by internal waves and how this variability may be useful in some important ways.

Though internal waves cannot propagate vertically through weakly stratified fluid, if the depth of the weak stratification is sufficiently shallow, these waves can partially transmit through it. This paper quantitatively extends previous results on Cartesian internal wave tunneling to the case of axisymmetric wave fields and proposes a simple three-layer model. We show that there exists a smooth transition between the fully propagating and the tunneling regimes. We further reflect on the challenges set by the measurement of internal wave mode amplitudes in confined domains, and we discuss an innovative method to measure said amplitudes in this experimental and numerical context.

In this work we consider a reduced system that models internal waves at the interface of two immiscible, inviscid, incompressible and irrotational fluids limited by a rigid lid at the top and a flat bottom. The system was previously derived by asymptotic expansions from the Euler equations for each layer and the complementary conditions that coupled them and consists of two integro-differential evolution equations for the interface wave profile and the upper layer averaged horizontal velocity. The aforementioned system is further reduced here to a single integro-differential evolution equation (the Regularized Benjamin equation) for the interface wave profile, in order to prove the existence of smooth periodic travelling wave solutions which capture the behaviour of internal waves observed in the ocean layers.
