  • In parts of the world, cool, high-salinity surface waters become so dense that they sink to great depths, where they become part of deep ocean currents. (nasa.gov)
  • Compared to terrestrial ecosystems, mangrove ecosystems are periodically inundated by the tides which contribute to the waterlogged and high salinity soil environment. (nature.com)
  • Soil Moisture and Ocean Salinity (SMOS) is a satellite which forms part of ESA's Living Planet Programme. (wikipedia.org)
  • It controls the growth of plants through water availability related to soil moisture and through radiation reaching the land surface-controlled largely by clouds-that is available for photosynthesis. (nationalacademies.org)
  • Its readings will complement and extend the efforts of the European Space Agency 's Soil Moisture and Ocean Salinity (SMOS) mission, which launched in November 2009. (livescience.com)
  • The SMOS and SMAP radiometers have demonstrated the ability to monitor soil moisture and sea surface salinity. (usu.edu)
  • Since ocean surface salinity generally averages just 32 to 37 parts per thousand around the globe, it's very hard for a satellite to detect its signal. (nasa.gov)
  • On a global scale, there are important gaps in knowledge of where water is stored, where it is going, and how fast it is moving. (nationalacademies.org)
  • Urban water-reuse is recognized as a promising and necessary measure to alleviate the growing water stress in many regions. (preprints.org)
  • One of them is through the Crop Water Stress Index (CWSI). (preprints.org)
  • The responses of a low-cost infrared (IR) sensor were crossed with image processing through segmentation by the Excess Green model to develop a water stress detection system using CWSI. (preprints.org)
  • Humans can live only a few minutes without oxygen, less than a week without water, and about a month without food. (pressbooks.pub)
  • Water also is essential for our oxygen and food supply. (pressbooks.pub)
  • Plants breakdown water and use it to create oxygen during the process of photosynthesis. (pressbooks.pub)
