One variation on this quantity is affected by the iron in aeolian dusts, while this value is limited in HNLC regions and decreases along with ocean depth due to the decrease in marine snow.
This quantity can be measured using the eddy covariance technique, and Gaarder and Gran developed a method of calculating this by observing the fluctuations in oxygen concentration in a sealed bottle. One variation on this quantity is affected by the iron in aeolian dusts, while this value is limited in HNLC regions and decreases along with ocean depth due to the decrease in marine snow. The f-ratio is proportional to this quantity in the upper zones of marine biomes, and on land the absorbed photosynthetically active radiation can be used to estimate its value. During the summer, the terrestrial type of this value increases due to maximal leaf area index, while in the ocean it decreases due to the presence of thermoclines. Linked tightly to the concept of biomass, for 10 points, name this quantity that measures the production of organic compounds from free carbon dioxide.
