The bottom current velocity is often close to zero at neap tides (Figure 2c), implying that the near-bottom currents are primarily driven by internal tides. These observations suggest that breaking of diurnal i
Here we develop a theoretical understanding for these currents, using a hierarchy of realistic and idealized models, focusing on the South Pacific Ocean. The deep eastern boundary current there is shown to be driven by a traditional interior balance together with a narrow boundary layer scale near...
As opposed to wind-driven currents and tides (the latter are due to the gravity of the Moon and the Sun), the THC is that part of the ocean circulation which is driven by fluxes of heat and freshwater across the sea surface and subsequent interior mixing of heat and salt; hence the na...

A decline in ocean circulation is expected to stagnate the bottom of the oceans and generate further impacts affecting the marine and climatic ecosystems for many centuries.
The deep-sea is part of the Earth's biosphere, yet so much of it remains unknown primarily because we have seen or sampled so little of it. Sampling issues will not fade away, and they are more important than ever because exploitation of natural resources often depends upon environmental ...

Ocean currents (洋流) are sometimes called “rivers in the sea ”. One of these “rivers ” in the Atlantic is called the Gulf Stream (墨西哥湾流). It is a current of warm water. Another is the Labrador Current---cold water coming down from the Arctic (北冰洋). Ocean currents affects...
Barotropic theories of the prominent western boundary currents in a flat-bottomed ocean use western boundary currents to close the mass budget due to the wind-driven interior flow and are based on a vorticity balance between term and friction, such as linear bottom drag in Stommel (1948) or la...
The abyssal realm is very calm, being far removed from storms that agitate the ocean at the air-sea interface. These low energies are reflected in the character of abyssal sediments. The abyssal realm is usually far enough from land that the sediment is composed predominantly of microscopic plan...
