NASA Aquarius Mission - The Role of Salt in Water
WebJul 28, 2014 · One reason scientists are so interested in changes in ocean surface salinity is that studies incorporating both observations and climate model simulations indicate that over time, global warming will intensify the water cycle: rainy areas will become even wetter and dry areas will become even drier. WebJul 12, 2014 · The ocean is the heart of Earth’s water cycle, and changes in the rate of evaporation and rainfall are reflected in the relative freshness or saltiness of the ocean surface. In addition, differences in salinity from place to place, along with temperature, drive the currents that move heat from the equator toward the poles. mary backous obituary
Non-equilibrium Entropy and Enthalpy of Seawater Evaporation
Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean. However these "salinity raising" factors are continually counterbalanced by processes that decrease salinity such as the continuous input of fresh water from rivers, precipitation of rain and snow, and melting of ice. See more Understanding why the sea is salty begins with knowing how water cycles among the ocean's physical states: liquid, vapor, and ice. As a liquid, water dissolves rocks and sediments and reacts … See more Surface winds drive currents in the upper ocean. Deep below the surface, however, ocean circulation is primarily driven by changes in seawater density, which is determined by salinity and temperature. In some regions such as … See more Data from Aquarius has unveiled a world of varying salinity patterns. The Arabian Sea, nestled up against the dry Middle East, appears much saltier than the neighboring Bay of Bengal, which gets showered by intense … See more Throughout most of history, global understanding of ocean surface salinity was difficult because sampling by ships, buoys, drifters, and moorings was extremely limited. Between 300 and 600 AD, awareness of … See more WebSalt in the ocean comes from two sources: runoff from the land and openings in the seafloor. ...
