This map is the solvent of one very busy calendar month of data collected by NASA ’s Aquarius instrument , pop the question the first ever world mapping of the ocean surface ’s saltiness . This selective information has potentially fundamental implications for our understanding of changing climates .
you may get across on the map up top to get a closer look at Aquarius ’s work . The map is crucial because the mode that salinity vary from place to place along the ocean surface plays a key role in the climate cycles/second . This is because salt levels are linked to the cause of fresh water all around the planet , as well as the circulation of sea electric current in oecumenical . Before Aquarius , we ’ve only had a rough melodic theme of how salinity vary in unlike locating , so this function provide a vital new clue in the exploit to understand the deeper mechanics of Earth ’s clime .
NASA ’s Jet Propulsion Laboratory offer this account of some of the key features :
The mapping indicate several well - know ocean saltiness sport such as higher salinity in the subtropics ; high mediocre salinity in the Atlantic Ocean compare to the Pacific and Amerindic oceans ; and lower salt in rainy belts near the equator , in the northernmost Pacific Ocean and elsewhere . These features are related to large - scale leaf patterns of rainfall and vaporization over the ocean , river outflow and sea circulation . Aquarius will monitor how these features alter and hit the books their link to climate and weather variations .
Other important regional features are evident , including a sharp contrast between the arid , high - salt Arabian Sea west of the Indian subcontinent , and the low - salinity Bay of Bengal to the east , which is dominated by the Ganges River and south Asia monsoon rains . The data also show important lowly details , such as a larger - than - expected extent of gloomy - salinity urine associated with efflux from the Amazon River .
