Daniel Thewes was born, raised and educated in Hamburg Germany. In 2016, he graduated with a Master of Science degree in physical oceanography from the University of Hamburg. His doctaral studies were carried out in the context of the project “Coastal Ocean Darkening” at the Carl von Ossietzky University of Oldenburg from 2016 to 2020. He re-joined the UHH in 2020 for the project “InterReg: Water Quality”, concerning itself with eutrophication parameters in the southern North Sea. Since the end of said project, he continued working in this field. He is associated with the Intersessional Correspondence Group on Eutrophication Modelling (ICG-EMO) within OSPAR.
