Integrations of coupled climate models with mixed-layer and fixed-current ocean components are used to explore the climatic response to varying magnitudes of ocean circulation. Four mixed-layer ocean experiments without ocean heat transports are performed using two different atmosphere–land components—the new GFDL AM2 and the GFDL Manabe Climate Model (MCM)—and two different sea ice components,...

sea surface topography (sst) by definition is the separation between the geoid and the mean sea level (msl). the separation between the geoid and msl is caused by various non-gravitational physical effects. if determination of the geoid as the zero point of the height systems from the tide gauge observation be the goal, it is necessary that the affect of the physical effect be precisely compute...

It is well recognized that most marine vertebrates, and especially tetrapods, precisely orient and actively move in apparently homogeneous oceanic environments. Here, we investigate the presumptive role of oceanic currents in biogeographic patterns observed in a secondarily marine tetrapod, the yellow-bellied sea snake (Hydrophis [Pelamis] platurus). State-of-the-art world ocean circulation mod...

This paper introduces an autonomous towed vehicle which has various navigation modes; towed mode, autonomous mode and kite mode, to stand against fast and changeable sea currents. The property assures safe and reliable observation works irrespective of a current speed. Such vehicle must be useful for port area application since in a port area sea currents are so fast and complex. The different ...

D I R E C T measurement of large-scale ocean currents with current meter arrays is difficult and costly on basin scales. Since large-scale currents are very nearly in geostrophic balance, their velocity can be calculated from the pressure gradient on an equigeopotential surface. The surface geostrophic current therefore can be calculated from the deviation of sea level from the equigeopotential...
