Abstract
Offshore wind energy is a steadily growing sector contributing to the worldwide energy production. The impact of these offshore constructions on the marine environment, however, remains unclear in many aspects. In fact, little is known about potential emissions from corrosion protection systems such as organic coatings or galvanic anodes composed of Al and Zn alloys, used to protect offshore structures. In order to assess potential chemical emissions from offshore wind farms and their impact on the marine environment water and sediment samples were taken in and around offshore wind farms of the German Bight between 22.07.2020 and 25.07.2020 within the context of the Hereon-BSH project OffChEm. At every sampling station oceanographic parameters were measured directly on board with respective probes of a multimeter for pH, dissolved oxygen, temperature and conductivity. Additionally the current associated weather conditions (temperature in air, wind speed, air pressure) were noted from the ship system.
