Trace metal distribution for water samples of ATAIR cruise AT261

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 the surrounding and within different wind farms of the German Bight in April 2018 within the context of the Hereon-BSH project OffChEm. The water samples were taken in metal-free GO-FLO sampling bottles, filtered over <0.45 µm polycarbonate filters into pre-cleaned LDPE bottles and acidified with nitric acid. […]

离岸风能产业作为全球能源生产领域稳步增长的板块，正日益贡献其力量。然而，这些离岸建筑对海洋环境的影响在诸多方面仍处于模糊不清的状态。实际上，关于用于保护离岸结构的有机涂层或由铝锌合金组成的电化学阳极等腐蚀防护系统的潜在排放，所知甚少。为评估离岸风电场潜在的化学排放及其对海洋环境的影响，Hereon-BSH项目OffChEm在2018年4月于德国湾周边及其不同风电场内采集了水体和沉积物样本。水体样本采集于无金属GO-FLO采样瓶中，经<0.45 µm的聚碳酸酯滤膜过滤至预先清洁的LDPE瓶中，并使用硝酸进行酸化处理。
