Short summary
We examine seasonality of planktic foraminifera in an upwelling area to identify species vulnerable to changes in upwelling and ocean acidification and improve interpretation of fossil foraminifera. Of species associated with upwelling on the central California shelf, some are consistent with observations elsewhere while some associations appear to be unique to the region. All species show lunar periodicity and we confirm the presence of foraminifera at very low saturation state of calcite.
