To test this hypothesis we present a series of experiments with an ocean biogeochemical model of the glacial ocean with and without inclusion of these particulate fluxes. Our work builds on previous box modeling studies by Tsandev et al. (2010) and Filippelli et al. (2007) for the glacial ocean and our own work on carbon (C), oxygen and phosphorus cycling in the present-day (pre-industrial) oce...

The paper describes changes in marine oxygen and phosphorus fields obtained for glacial and interglacial environmental conditions with a global ocean circulation model. A main result is that reasonable patterns of glacial oxygen and reactive P burial can only be obtained with the input of terrigenous particulate organic C and P. This hypothesis is of great scientific interest, and the manuscrip...

[. . .] The main problems are the lack of mechanistic insight, data constraints, or testable predictions. The model is used to calculate things, and the results of the calculations are presented with little discussion for the underlying processes. Although interesting, I am left uncertain as to whether the results have any relevance to reality. I would suggest a thorough rewrite of the paper th...
