Marine nitrogen fixers mediate a low latitude pathway for atmospheric CO2 drawdown

Marine nitrogen fixers mediate a low latitude pathway for atmospheric CO2 drawdown

Iron fertilisation of the high latitude oceans is a well-established biological mechanism to explain the ice age drawdown of atmospheric CO2, yet modelling has so far struggled to account for a sufficient drawdown via this mechanism. Here, the authors propose that N2 fixers, which inhabit the lower...
