A look at N2O: Nitrous oxide emissions may be higher than previously thought
June 22, 2015 05:01 PM - Helmholtz Centre for Ocean Research Kiel
In addition to carbon dioxide there are plenty of other greenhouse gases. Nitrous oxide is one of them. However, a global assessment of emissions from the oceans is difficult because the measurement methods used so far have only allowed rough estimates. Using a new technology for continuous measurements, researchers of the GEOMAR Helmholtz Centre for Ocean Research Kiel and the Christian-Albrechts-Universität zu Kiel have now discovered that nitrous oxide emissions from the Southeast Pacific are much higher than previously thought. They publish their data in the international journal Nature Gesoscience.

Plants need water. People need water. Unfortunately, there’s only so much clean water to go around — and so the effort begins to find a solution.
Luckily for people, some plants are able to make do without perfectly clean water, leaving more good water for drinking. One strategy is to use treated wastewater, containing salt leftover from the cleaning process, to water large areas of turf grass. These areas include athletic fields and golf courses. Golf courses alone use approximately 750 billion gallons of water annually in arid regions.
However, most plants cannot tolerate a lot of salt. As some areas of the United States run low on clean water, plant breeders are trying to breed plants that are more salt tolerant. This would conserve clean water while maintaining healthy turf.
Plant breeders can actually see the individual effect of what each parent plant passes on because the genes add intensity to the trait. These are additive effects. Breeders can more easily select for those features when they observe those differences.
