KOSMOS mesocosm experiment Bergen 2022 on ocean alkalinity enhancement: fish abundance, biomass and sedimentation@en

Fish during the mesocosm experiment in Raunefjord near Bergen (Norway) in spring/summer 2022. Larvae of several coastal fish species were enclosed naturally (day 0) and supplemented with 95 herring larvae reared in the laboratory (day 6). Following the OAE treatment (day 6), deceased fish larvae were monitored via the sediment trap in 2-day intervals to approximate mortality. At the end of the experiment (day 54), all live fish were caught to assess abundance, biomass and taxonomic composition. Methodological details in Goldenberg et al. (under review).本数据集涵盖2022年春夏于挪威卑尔根附近劳内峡湾（Raunefjord）开展的围隔实验（mesocosm experiment）中的鱼类样本。实验第0天，多种沿岸鱼类的幼体被自然纳入围隔装置；实验第6天，额外投放95尾实验室繁育的鲱鱼幼体。完成OAE处理（实验第6天）后，通过沉积物捕集器以每2日一次的间隔对死亡的鱼类幼体进行监测，以估算死亡率。实验结束时（第54天），捕获全部存活鱼类以评估其丰度、生物量及分类学组成。实验方法的详细细节参见Goldenberg等人（审稿中）的研究。
