摘要
An estimated amount of 3.7×10~5 petagrams(1 Pg=10^(15)g)of organic carbon is stored in marine sediments(Lipp et al.,2008),which supports an immense subsurface biosphere that contains approximately 2.9×10^(29)to 3.6×10^(30)cells of indigenous microorganisms(Kallmeyer et al.,2012;Whitman et al.,1997).The majority of that carbon is transported from surface oceans by a process called the'biological pump(BP)',which has been a prevailing doctrine in the ocean carbon cycle.
