Alkalinity is a measure of the ability of seawater to neutralize acids. This visualization shows monthly surface total alkalinity (TA) from August 2011 to May 2015 as derived using data from NASA’s Aquarius mission. Utilization of Aquarius data allows unprecedented global mapping of surface TA as it correlates strongly with salinity and to a lesser extent with temperature.For the first time, Aquarius data are allowing scientists to observe changes in surface alkalinity over time. For example, they have found that the Northern Hemisphere has more spatial and monthly variability in total alkalinity and salinity, while less variability in Southern Ocean alkalinity is due to less salinity variability and upwelling of waters enriched in alkalinity. Increasing surface TA in subtropical regions from increasing salinity and temperature causes the saturation states of calcite and aragonite to decrease, i.e., enhanced dissolution. Thus, based on increasing TA in the subtropical regions over the past few decades, it is expected that it is becoming more difficult for calcifying organisms to make their shells. || ", "hits": 171 }, { "id": 30496, "url": "https://svs.gsfc.nasa.gov/30496/", "result_type": "Hyperwall Visual", "release_date": "2015-03-17T00:00:00-04:00", "title": "Earth Observing Fleet", "description": "Like orbiting sentinels, NASA’s Earth-observing satellites vigilantly monitor our planet’s ever-changing pulse from their unique vantage points in orbit.

During its nominal three-year mission, Aquarius will map the salinity at the ocean surface to improve our understanding of Earth's water cycle and ocean circulation. Aquarius will help scientists see how freshwater moves between the ocean and the atmosphere. It will monitor changes in the water cycle due to rainfall, evaporation, ice melting, and river runoff. Aquarius will also demonstrate a measurement capability that can be applied to future operational missions. Ocean circulation is driven in large part by changes in water density, which is determined by temperature and salinity. Cold, high-salinity water masses sink and trigger the ocean's \"themalhaline circulation\" - the surface and deep currents that distribute solar energy to regulate Earth's climate. By measuring salinity, Aquarius will provide new insight into this global process. Aquarius' measurements of ocean salinity will provide a new perspective on the ocean and its links to climate, greatly expanding upon limited past measurements. Aquarius salinity data - combined with data from other sensors that measure sea level, ocean color, temperature, winds and rainfall will give us a much clearer picture of how the ocean works, how it is linked to climate, and how it may respond to climate change.Aquarius will provide information that will help improve predictions of future climate trends and short-term climate events such as El Niño and La Niña.
