Matt Long (Sep 03 2020 at 15:03): Matt Long (Sep 03 2020 at 15:03):@all, what are your favorite papers on multiple stressors (T, pH, NPP decline, deoxygenation)? (I have to assign some reading ASAP for a lecture at WHOI/MIT in a couple weeks.)
Kristen Krumhardt (Sep 03 2020 at 15:07):Gruber 2011 comes to my mind when thinking about multiple stressors:

Kristen Krumhardt (Sep 03 2020 at 15:21):There are also some interesting laboratory studies with coccolithophores that I find interesting... for example, this one by Milner et al.:

The ocean is a sink for ~25% of the atmospheric CO2 emitted by human activities, an amount in excess of 2 petagrams of carbon per year (PgC yr−1). Time-resolved estimates of global ocean-atmosphere CO2 flux provide an important constraint on the global carbon budget. However, previous estimates of this flux, derived from surface ocean CO2 concentrations, have not corrected the data for temperature gradients between the surface and sampling at a few meters depth, or for the effect of the cool ocean surface skin. Here we calculate a time history of ocean-atmosphere CO2 fluxes from 1992 to 2018, corrected for these effects. These increase the calculated net flux into the oceans by 0.8–0.9 PgC yr−1, at times doubling uncorrected values. We estimate uncertainties using multiple interpolation methods, finding convergent results for fluxes globally after 2000, or over the Northern Hemisphere throughout the period. Our corrections reconcile surface uptake with independent estimates of the increase in ocean CO2 inventory, and suggest most ocean models underestimate uptake.
