TL;DR: Although ∼10% of the ocean's drawdown of atmospheric anthropogenic carbon dioxide may result from this atmospheric nitrogen fertilization, leading to a decrease in radiative forcing, up to about two-thirds of this amount may be offset by the increase in N2O emissions.

TL;DR: In this article, the late Quaternary history of water column denitrifcation of the eastern Pacific margins and the Arabian Sea is reconstructed using sedimentary δ15N measurements.

TL;DR: The GEOTRACES Intermediate Data Product 2017 (IDP2017) as discussed by the authors is the second publicly available data product of the international GEOTrACES programme, and contains data measured and quality controlled before the end of 2016.

TL;DR: This study suggests the paradoxical decline in opal accumulation rate in the glacial EEP results from a decrease in the silicon to carbon uptake ratio of diatoms under conditions of increased iron availability from enhanced dust input, and supports the idea of an invigorated biological pump during the last glacial period that could have contributed to glacial carbon dioxide drawdown.
