Redfield (1934), who analyzed the major elemental content of many samples of mixed plankton (phytoplankton and zooplankton) caught in nets towed through the surface ocean. They compared the carbon, nitrogen, and phosphorus composition of these collections to concentration profiles of dissolved inorganic carbon (DIC), NOs, and P04 throughout the water column. This pioneering research demonstrated that these three elements are continually redistributed in the ocean by selective removal into plankton cells and their remains (i.e., fecal pellets), which are then efficiently respired as they sink through the marine water column. 

Figure 9.1 Freshwater-marine mixing ratios of dissolved inorganic carbon (DIC) and isotopic composition (DI13C) across three different salinity gradients. Bottom isotopic change between — 10%e at the freshwater end-member, and +2%c at the marine end-member, both end-member values are based on concentration-weighted averages (data sources Spiker and Schemel, 1979 Spiker, 1980).

Compared with the atmosphere, where most carbon is presented by CO2, oceanic carbon is mainly present in four forms dissolved inorganic carbon (DIC), dissolved organic carbon (DOC), particulate organic carbon (POC), and the marine biota itself. 

The flow of carbon in the marine part of the biochemical subcycle involves buffering by the large reservoir of dissolved C (39 T t), most of which is in the form of dissolved inorganic carbon (DIC). Whereas terrestrial plants take up carbon dioxide directly from the atmosphere in gaseous form, aquatic plants utilize the C02 dissolved in water, and it is for this reason that the photosynthesis and respiration flux arrows in Fig. 6.1 do not point directly to marine biota. A dynamic equilibrium exists whereby C02 molecules are constantly exchanging between the atmosphere and oceans (where it...
