Sentences with phrase «ocean salinity measurements»

The integrated measures from large - scale ocean salinity measurements are quite good, but it is difficult to work out exactly where that freshwater has come from.

«This study is the first to show the value of using ocean salinity measurements to forecast the intensity of tropical cyclones,» said team lead Dr. Karthik Balaguru, an oceanographer at PNNL's Marine Sciences Laboratory.

Its measurements of ocean saltiness will also help scientists understand how changes in salinity affect the deep currents that drive ocean circulation.

DeVries and fellow researchers Mark Holzer of the University of New South Wales in Sydney and François Primeau of UC Irvine compiled existing oceanographic tracer data — measurements of temperature, salinity, CFCs (humanmade gases that dissolve into the ocean) and carbon - 14 — and separated it into three decade - long time periods: the 1980s, the 1990s and the 2000s.

Temperature and salinity measurements averaged between 2010 and 2014 to show ocean alkalinity.

The patterns of salinity change can be used to infer changes in the Earth's hydrological cycle over the oceans (Wong et al., 1999; Curry et al., 2003) and are an important complement to atmospheric measurements.

There's no satellite in space that's capable of directly measuring ocean acidity, but an international team of scientists writing in the journal Environmental Science & Technology described last week how satellite measurements of sea surface temperatures, salinity and plankton activity could be combined and used to estimate pH.

Yet measurements from more than 3600 automated buoys throughout the ocean that dive down a mile and a quarter and take detailed temperature and salinity profiles every ten days show that the deeper strata are warming faster than the near - surface strata.

The principal scientific objective is to make global SSS measurements over the ice - free oceans with 150 - km spatial resolution, and to achieve a measurement error less than 0.2 (PSS - 78 [practical salinity scale of 1978]-RRB- on a 30 - day time scale, taking into account all sensors and geophysical random errors and biases.Salinity is indeed a key indicator of the strength of the hydrologic cycle because it tracks the differences created by varying evaporation and precipitation, runoff, and ice processes.

To conduct the research, a team of scientists led by John Fasullo of the US National Center for Atmospheric Research in Boulder, Colorado, combined data from three sources: NASA's GRACE satellites, which make detailed measurements of Earth's gravitational field, enabling scientists to monitor changes in the mass of continents; the Argo global array of 3,000 free - drifting floats, which measure the temperature and salinity of the upper layers of the oceans; and satellite - based altimeters that are continuously calibrated against a network of tide gauges.

Nonetheless, the findings demonstrate that satellite - based measurements of Arctic sea surface salinity are reasonably accurate and successfully reflect changes due to river runoff, melting sea ice and glaciers, and ocean circulation.

These advances include the near - global three - dimensional sampling by the Argo array of temperature and salinity profiling floats and spaceborne measurements of sea surface salinity using the European Space Agency's Soil Moisture and Ocean Salinity (SMOS) spacecraft and NASA's Aquarius mission aboard the Argentine SAC - D spacecraft (which ceased operations in Junsalinity profiling floats and spaceborne measurements of sea surface salinity using the European Space Agency's Soil Moisture and Ocean Salinity (SMOS) spacecraft and NASA's Aquarius mission aboard the Argentine SAC - D spacecraft (which ceased operations in Junsalinity using the European Space Agency's Soil Moisture and Ocean Salinity (SMOS) spacecraft and NASA's Aquarius mission aboard the Argentine SAC - D spacecraft (which ceased operations in JunSalinity (SMOS) spacecraft and NASA's Aquarius mission aboard the Argentine SAC - D spacecraft (which ceased operations in June 2015).

Despite its importance, ocean salinity in the Arctic has been poorly monitored because of the harsh environment and obstacles posed by sea ice, which impede field measurements.

Any field - or ship - based updates on ice conditions in the different regions such as sea ice morphology (e.g., concentration, ice type, floe size, thickness, snow cover, melt pond characteristics, topography), meteorology (surface measurements) and oceanography (e.g., temperature, salinity, upper ocean temperature).

Perhaps the measurement of the distribution of the temperatures, salinity and velocities fields in the oceans will allow an estimate of the heat flux coming from the surface of the ocean relative to that coming from the ocean depths.

Other new products are the ocean reanalyses (ECCO for instance) that tries to take the same approach with ocean temperature and salinity measurements.
