Scene 1 (0s)
Ocean Carbon Cycle.
Scene 2 (6s)
Background. Main reservoirs of carbon are the atmosphere, ocean, vegetation, soils and detritus on land (Geologic reservoirs important on multi-millennial time scales). Various processes transfer carbon between these reservoirs, including photosynthesis, respiration, ocean-atmosphere gas exchange and ocean mixing..
Scene 3 (23s)
Carbon Storage Tonnes of Carbon per Hectare* Vegetation 64 Boreal forests 344 Soil - Tundra Temperate forests 96 43 Wetlands Soil contains almost 2X as much carbon as the atmosphere and living flora and animals combined. Temperate grasslands 236 29 Tropical savannas 120 Tropici forest 123.

Scene 5 (59s)
Phytoplankton provide the base of the marine food web as well as oxygen that gets released into the atmosphere (generate ½ of the O2 that all animals need to breathe). They provide nutrients to the rest of the marine food web.
Scene 6 (1m 18s)
Ocean carbon cycle coz Biological Pump Phytoplankton Photosynthesis Microbial Respiration 2 C02 Particulate Carbon Flux C02 Zooplankton Grazing coz C02 The ocean holds 50 times more C02 than the atmosphere.
Scene 7 (1m 28s)
Ocean acidification reduces the production of calcium carbonate (CaCO 3 ; limestone) by organisms (corals, plankton) CO2 is dissolved into water to create carbonic acid (H2CO3).
Scene 8 (1m 44s)
OCEAN ACIDIFICATION. How WILL CHANGES IN OCEAN CHEMISTRY AFFECT MARINE LIFE? C02 carbon dioxide H20 + C03- water carbonate ion C02 absorbed from the atmosphere 2 HCOE 2 bicarbonate ions consumption of carbonate ions impedes calcification.

Scene 10 (2m 17s)
P ositive Feedback: A slowing of ocean circulation caused by global warming reduces the mixing of nutrients therefore slowing biological productivity. Weakening biological pump reduces the ocean’s ability to absorb CO 2 ..
