Wc15 - global size and distribution of carbon stores

• how is carbon stored in the lithosphere?


  marine sediments and sedimentary rocks: 100 million GtC

  soil organic matter: 1,500-1,600 GtC

  fossil fuels: 4,100 GtC

  peat: 250 GtC
• what is the total carbon stored in the lithosphere?


  100,005,850-100,005,950 GtC
• how is carbon stored in the hydrosphere?


  euphotic zone: 900 GtC

  twilight zone: 37,100 GtC

  living organic matter: 30 GtC

  dissolved organic matter: 700 GtC
• what is the total carbon stored in the hydrosphere?


  37,000-40,000 GtC
• how is carbon stored in the biosphere?


  terrestrial biosphere: 3,170 GtC

  living vegetation = 19% of carbon

  soil = 69% of carbon

  
  

  peat: 250 GtC
• terrestrial carbon stores by ecosystem

  
• what is the total carbon stored in the atmosphere?


  720-800 GtC
• what is net primary productivity?


  how much carbon dioxide vegetation takes in during photosynthesis minus how much carbon dioxide the plants release during respiration
• how is carbon storage changing in the terrestrial biosphere?


  -increasing in middle and high latitudes of the northern hemisphere due to boreal and coniferous forest and the effect of seasonality

  -decreasing in the tropics due to drought linked to climate change
