Research interests Coccolithophores for paleoceanographic and paleoclimate reconstruction.
Export production, transport and sedimentation of biogenic carbonate particles onto the deep seafloor. My previous work experiences are in the export production and seasonal distribution of coccolithophores in the eastern Pacific focussing in San Pedro Basin, Southern California, and Guaymas Basin, Gulf of California and export production and preservation of biogenic carbonate in the Eastern Mediterranean. D thesis of Sandra Broerse on the redefinition of the coccolithophore biogeography based on time series sediment traps from different oceanographic settings. We use sediment traps in order to quantify and model coccolithophore seasonal export production and transformation of their assemblages during the sinking and burial processes. Through sediment trap studies we are able to document the environmental factors which control the production and distribution of various plankton groups in relation to climate changes.
