Ocean stoichiometry, global carbon, and climate.
Autotrophs bridge the nonliving (CO2) and living (organic carbon) realms by fixing carbon through photosynthesis. All life is based on multiple functions that differ in their elemental requirements, and homeostasis of cellular composition is one of the hallmarks of life. Nevertheless, autotrophs on land and in water have the biological potential to adjust their nutrient content in response to n...
متن کاملGlobal Teleconnections of Ocean Climate to Terrestrial Carbon Flux
We have applied association analysis to 17 years of ocean climate observations and predicted net ecosystem production on land to infer short-term (monthly to yearly) teleconnections between sea surface temperature and terrestrial carbon cycles. The analysis suggests that, on a global level, ocean climate indices can be used to reliably predict net ecosystem carbon fluxes over more than 58 perce...
متن کاملOcean carbon sinks and international climate policy
Terrestrial vegetation sinks have entered the Kyoto Protocol as offsets for anthropogenic greenhouse gas emissions, but ocean sinks have escaped attention. Ocean sinks are as unexplored and uncertain as were the terrestrial sinks at the time of negotiation of the Kyoto Protocol. It is not unlikely that certain countries will advocate the inclusion of ocean carbon sinks to reduce their emission ...
متن کاملClimate, carbon cycling, and deep-ocean ecosystems.
Climate variation affects surface ocean processes and the production of organic carbon, which ultimately comprises the primary food supply to the deep-sea ecosystems that occupy approximately 60% of the Earth's surface. Warming trends in atmospheric and upper ocean temperatures, attributed to anthropogenic influence, have occurred over the past four decades. Changes in upper ocean temperature i...
متن کاملThe Southern Ocean, carbon and climate.
The Southern Ocean fascinates us. It retains an aura of mystery from the time of the early European explorers, when to sail through the Straits of Magellan or around Cape Horn was to leave the known world behind. Then, as now, the waters of the Southern Ocean earned a reputation as the roughest and most challenging on the Earth, a test for the bravest of mariners. Many that sailed there never r...
