Abstract
We used an earth system model of intermediate complexity to study the
effects of Solar Radiation Management (SRM) by sea spray geoengineering
on ocean biogeochemistry. SRM slightly decreased global ocean net
primary productivity (NPP) relative to the control run. The lower
temperatures in the SRM run decreased NPP directly but also indirectly
increased NPP in some regions due to changes in nutrient availability
resulting from changes in ocean stratification and circulation. Reduced
light availability had a minor effect on global total NPP but a major
regional effect near the nutrient rich upwelling region off the coast of
Peru, where light availability is the main limiting factor for
phytoplankton growth in our model. Unused nutrients from regions with
decreased NPP also fueled NPP elsewhere. In the context of RCP4.5
simulation used here, SRM decreased ocean carbon uptake due to changes
in atmospheric CO_2 concentrations, seawater chemistry, NPP,
temperature, and ocean circulation.
