Smith Friday, March 6 Today Gases P, V, n, T Ideal gas law Motion of molecules: kinetic theory of gases Read Chapter 5 Mastering Chemistry online homework ( Due 3/17 ) Iron helps oceans capture more carbon 8 January 2009 team of international scientists studying the role of iron in the storage of carbon under the ocean have onfirmed that natural iron fertilisation increases the ate of carbon capture. However, the group's easurements conflicts with previous studies - and dds to ongoing concerns over planned experiments to artificially fertilise the oceans with iron as a tool to ut carbon dioxide from the atmosphere. Iron's role in the ocean carbon cycle is to promote the rowth of phytoplankton, which remove carbon dioxide from the air through photosynthesis. Whilst most of the carbon in the resulting biomass will re-enter the tmosphere through the carbon cycle, a small amount ill fall into the depths of the ocean as the plankton ies, effectively locking away that carbon for up to 300 ears. The theory is that the more phytoplankton there re, the more carbon will be stored in the depths of the sea.
