Surf Zone Wave Breaking Identification Using Marine Radar
This paper presents a novel combination of synchronous, large coverage marine radar, calibrated pulsed Doppler radar, and video remote sensing observations from a nearshore field site. The data enable the analysis of the evolution and characteristics of the remotely observed signals from surf zone waves. The combination of different remote sensors allows a better discrimination between breaking...
متن کاملScaling surf zone turbulence
[1] Turbulence in the surf zone, the shallow region adjacent to the shoreline, has a key role in beach erosion, fertilization, dispersal, and larval settlement of marine invertebrates, and microbial contamination dilution in beach waters. Breakingwave generated (the dominant source) surf zone turbulence is understood poorly. A new surf zone turbulent dissipation rate scaling is derived, that co...
متن کاملRotational surf zone modeling for Oðl4Þ Boussinesq–Green–Naghdi systems
A surf zone model is developed and tested based on the Oðl4Þ Boussinesq–Green–Naghdi system of Zhang et al. (2013). Because the model is fundamentally rotational, it uses fewer ad hoc assumptions than are found in many Boussinesq breaking wave systems. Eddy viscosity is used to describe both breaking dissipation and bottom friction, with breaking viscosities derived from the turbulent kinetic e...
متن کاملComment on Enhanced TKE Dissipation under Breaking Waves
It is noted that the results of recent experiments on the enhancement of turbulent kinetic energy (TKE) dissipation below surface waves can be stated as follows. TKE dissipation is enhanced by a factor 15Hws/z at depths 0.5Hws < z < 20Hws with respect to the wall-layer result ǫ = u ∗w/κz, where u∗w is the friction velocity in water and Hws is the significant windsea wave height. For open ocean ...
متن کاملDisseminating melanoma cells surf on calcium waves
Dysregulated calcium signaling has been increasingly implicated in tumor dissemination and progression. In a recent study we investigated the mechanism underlying calcium-mediated melanoma invasion and metastasis, and discovered that hyperactive Ca2+ oscillation in melanoma cells promoted invasion and metastasis through promoting invadopodium formation and extracellular matrix remodeling.
