Importance of natural forcing events in marine biogeochemistry of coastal NW Mediterranean

Which are the main factors on influence the dinamics of fluorescent dissolved organic matter in the coastal NW Mediterranean?

Dr. Fran Aparicio

Natural forcings (such as strong wind episodes, precipitation and river discharges) influence the marine biogeochemistry cycles in coastal and open ocean. To test the importance of these factors in the NW Mediterranean Sea, a four-year monitoring program was carried out on L’Estartit Oceanographic Station (EOS).

The work was led by the Marine Biology Department of the Institute of Marine Sciences (ICM-CSIC, Barcelona). In this study (Aparicio et al., 2017), the variability of several oceanographic variables (inorganic nutrients, dissolved organic carbon and fluorescent dissolved organic matter) was analyzed. The results showed that FDOM dynamics was predominantly affected by wind-induced processes. Hence, the authors concluded that wind-induced effects (such as upwelling and mixing events) can modify the proportion of the recalcitrant dissolved organic matter in coastal waters.
