Seawater and sediment data from offshore wind farms in the German Bight collected during the cruise AT275@en

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 06.03.2019 and 24.03.2019.海上风电产业正稳步增长，为全球能源生产贡献重要力量。然而，此类海上设施对海洋环境的影响，在诸多方面仍有待明确。事实上，目前人们对用于保护海上结构的腐蚀防护系统——如有机涂层或铝锌合金制成的牺牲阳极（galvanic anodes）——可能产生的排放情况知之甚少。为评估海上风电场的潜在化学排放及其对海洋环境的影响，研究人员于2019年3月6日至2019年3月24日期间，在德国湾（German Bight）的海上风电场及其周边海域采集了水体与沉积物样本。
