Biogeochemical processes in the Northeast Atlantic continent-ocean Boundary (Nothern Galician Rias, NW Iberian Peninsula)
This doctoral thesis deals with the biogeochemical processes taking place in estuarine systems known as 'rias', located at the NW of the Iberian Peninsula. Its realization has been possible thanks to financial support from the JAE-Program of the Spanish Council for Scientific Research (CSI...
