Asymptotic behavior of tidal damping in alluvial estuaries

[1] Tidal wave propagation can be described analytically by a set of four implicit equations, i.e., the phase lag equation, the scaling equation, the damping equation, and the celerity equation. It is demonstrated that this system of equations has an asymptotic solution for an infinite channel, reflecting the balance between friction and channel convergence. Subsequently, explicit expressions f...

Tidal modulation of incident wave heights: Fact or Fiction?

This contribution investigates the hypothesis that incident wave power is modulated by the tide. Eulerian measurements of wave height recorded by three wave buoys in intermediate water depths (8-45 m A.C.D.), over a seven year period were analysed in a search for evidence of this semi-diurnal variability in incident wave heights. The study site (Perranporth, UK) was a highly macrotidal environm...

Spatial and Temporal Patterns of Tidal Dissipation in Synchronous Satellites

Introduction: Tidal heating is an important energy source for several solar system bodies, and there is a wide-spread perception that the pattern of surface heat flow is diagnostic of internal structure. We wish to clarify that situation. Our analysis depends upon two important assumptions: First, that heat transport is dominated by conduction. Second, that the body can be modeled by a sequence...

Global Hyper-synchronous Spontaneous Activity in the Developing Optic Tectum

Studies of patterned spontaneous activity can elucidate how the organization of neural circuits emerges. Using in vivo two-photon Ca(2+) imaging, we studied spatio-temporal patterns of spontaneous activity in the optic tectum of Xenopus tadpoles. We found rhythmic patterns of global synchronous spontaneous activity between neurons, which depends on visual experience and developmental stage. By ...
