Manganese in seawater and the marine manganese …

01/09/1977· NADW has a TDM value of about 0.02 ppb in the Sargasso Sea ; therefore if the high manganese is a hydrographic feature AABW must have a manganese concentration of 0.67 ppb (this is a lower limit, because some of the original TDM of AABW would be scavenged). In light of data presented here, this seems unlikely. The following argument, based on a simple box model for Sta. 120, shows that ...

Abundance of elements in Earth's crust - Wikipedia

The abundance of elements in Earth's crust is shown in tabulated form with the estimated crustal abundance for each chemical element shown as mg/kg, or parts per million (ppm) by mass (10,000 ppm = 1%).. Estimates of elemental abundance are difficult because (a) the composition of the upper and lower crust are quite different, and (b) the composition of the continental crust can vary ...
