The physical ...
As wind moves across the surface of the ocean, friction between moving air and the water surface causes water to begin to move as well. This transfer of energy by friction is how wind causes surface currents. Once water at the surface begins to move, some energy gets transferred to deeper ...
InIndian Ocean: Surface currents Ocean surface circulation is wind-driven. In the monsoon zone, surface circulation reverses every half year and features two opposing gyres (i.e., semi-closed current systems exhibiting spiral motion) that are separated by the Indian subcontinent. During the northeas...
This causes the surface currents to expedite in over three-fourths of the world’s oceans.The growing speed of rotating ocean currents, called gyres, was linked with a deceleration of ocean circulation below. The team made a direct correlation between the trend and the existence of highly ...
In the eastern basin, the current ISV is substantial at 80°–90°E, especially for the equatorial upper ocean currents. Mooring observations have revealed that the ISV of currents at 90°E has a dominant period of 30–50 d and can extend to 390 m depth, but most of the energy is con...
Three different boundary conditions are considered. Firstly, with a condition of zero vorticity gradient normal to the boundary, inertial Fofonoff gyres, which coincide...会议名称: Coastal Ocean and Semi-Enclosed Seas: Circulation and Ecology Modeling and Monitoring 会议时间: 1998/09/08 ...
that are indirectly related to ocean currents, we are now poised to define ecoregions that meaningfully delimit marine biological communities based on their connectivity and to follow their evolution over time. Through a time-dependent complex network framework applied to a thirty-year long dataset of...
The SOI component is largest in the western and central tropical Pacific, but can also be seen in the Indian Ocean. Seasonal variations reveal details such as the gyre-scale shifts in the convergence centers of the subtropical gyres, and the seasonal evolution of tropical currents and eddies in...
Autocorrelation lengths of up to 3,000 km are found along major currents and basin gyres while autocorrelation lengths as low as 50 km are found in coastal regions and other areas of physical turbulence. Zonal (eastwest) autocorrelation lengths are typically longer than their meridional counterparts...

Marine plastics can have several impacts, such as degradation of habitats, impairment to navigation, contamination of environments, and direct effects on biota through ingestion, asph...
