My thesis is focused on the study of the effect of extreme events (ECE) on the biogeochemistry of shallow coastal areas (Bay of Cadiz). During my doctoral thesis, I am carrying out different samplings to collect data on biogeochemical fluxes and sediment properties in the Bay of Cadiz. The aim is to integrate all these data into a biogeochemical model that will help us to predict the effects of climate change in our study area. For the measurement of biogeochemical fluxes, we performed oxygen microprofiles and core incubations in the laboratory. However, these data only represent a small part of the variability of the system in terms of habitats and spatial variations. Therefore, my research visit at SDU will allow me to apply new techniques with higher spatial resolution, such as aquatic eddy covariance (ECV). The use of ECV will allow us to gain new insights into the functioning of the different aquatic substrates in the Bay of Cadiz, and will help us to predict the possible environmental impacts of extreme events on biogeochemistry and sediment metabolism
