Biounlimited elements

Biounlimited element An element whose marine distributions are controlled primarily by physical processes and are relatively uninfluenced by biogeochemical phenomena. These elements demonstrate conservative behavior. 

Table 15.6 gives a summary of calculations for some examples of biolimiting, biointermediate, and biounlimited elements. For biolimiting elements g is close to unity and/ < 0.1 for biounlimiting elements g must be very small... 

In the ocean, the halogens form part of a group of elements classified as biounlimited. Elements in this group have concentration ratios that are constant in samples from all locations, from surface level to deep water. By measuring the concentration of one element in this group, the composition of all other biounlimited components can... 

Table 9.1 contains a summary of recycling efficiencies for a variety of representative elements. The results fall into three groups, which have been termed biolimiting, biointermediate, and biounlimited. The biolimiting elements have 1 and, thus, are almost...
