Despite being the largest High Nitrate Low Chlorophyll (HNLC) region, the Southern Ocean sustains phytoplankton blooms through the summer, when presumably there is sufficient light, but nutrients in the euphotic zone have been depleted. Physical processes that can potentially supply nutrients from subsurface waters to the euphotic zone, and promote phytoplankton growth in the summer, have not b...

In this study, a fast shake mixing control system that allows control of the quantity of air entrainment, involving low mechanical stress and fluid bubbling by means of the suppression the sloshing of a fluid’s surface, is developed. Mixing by means of horizontal shaking in a circular motion is addressed, with a CFD simulator being used for analysis of the liquid’s behavior, and the quantity of...

In the eastern Alboran Sea, frontogenesis (FG) is a dominant process for fronts extending from Spanish coast toward basin interior, promoting large vertical displacements that connect surface mixed layer with oceanic interior. Using realistic, high-resolution model simulation this region, we conduct offline advection of virtual water parcels released near during 2-day episode intense FG. Three-...

A coupled wave–tide–circulation model is used to investigate wave–current interactions (WCIs) over the shelf waters of Northwest Atlantic (NWA) during Hurricane Earl (2010). WCIs have substantial impacts on hydrodynamics in upper ocean. The significant wave heights are modulated by WCIs, particularly regions with strong current gradients, a reduction up ~2.1 m (20%) storm. Noticeable decreases ...

The optically induced electron dynamics at a Si(001) surface is studied using a five-wave-mixing setup which measures the diffracted second-harmonic intensity induced by three ultrashort (13 fs) laser pulses. Depending on the time ordering of the pulses, this technique is capable of monitoring the temporal evolution of photoexcited one- or two-photon coherences, or populations. For a particular...

Aims. Planets with large moon(s) or those in the habitable zone of low-mass stars may experience much stronger tidal force and tide-induced ocean mixing than that on Earth. Thus, vertical diffusivity (or, more precisely, diapycnal diffusivity) such planets, which represents strength ocean, would be greater In this study, we explore effects extremely high circulation surface climate Earth-like p...

For implementation&#10 of the free surface boundary condition, a new subroutine has been introduced to an existing steady 3-D body fitted code. This code was previously written for steady flow simulation in closed ducts. The algorithm used in this subroutine reduces the instability problem according to the free surface wave generation. For code validation, it was applied to two different open c...
