Abstract

Abstract

Four methods are used to estimate the heat flux from the hydrothermal system to the ocean.The heat flux from high temperature vents and low temperature warm water diffusion fields is about 357 GW.The heat flux from bottom thermal boundary layer is 32 GW.Based on Baker's linear relationship between spreading rate and plume incidence,the possibly total hydrothermal fields on the whole world ocean are calculated and then their heat flux estimate is about 1 086 GW.Based on the spreading axiscrust cooling model the result is about 592 GW.From the results it can be seen that the heat flux from the hydrot hermal system to the world ocean may be tens to thousands giga-watt on one hand,and on the other hand it is well known that it is not easy to estimate it actually now.The great differ ence comes mainly from limited knowledge about the distribution of the hydrothermal fields on the world ocean.The abovementioned analysis is shown that though the heat flux from the hydrothermal system to the ocean is much smaller than the heat flux from the solar radiation to the ocean,but concerning the different ways of supplying the world ocean with heat,much attention should be paid to the effects of the hydrothermal activity on the world ocean current and world climate.
