本資料集提供2017年10月至12月於台南市安平歷史水景公園人工浮島上進行附生矽藻培養，並進行4次採集與藻種鑑定所得結果，於附著藻板之矽藻共鑑定出22屬45種，其中以菱形藻屬(Navicula)種類最多，Achnanthes subsessilis 及 Nitzschia longissima為數量優勢藻種。

The dataset provide the records of benthic diatoms attached on the diatom boards which were set on the artificial floating islands (AFIs) established on seawater in Anping Historical Waterview Park in Tainan, Taiwan. Diatoms were cultured with diatom boards and sampled four times from October to December of 2017. A total of 45 diatom species belonging to 22 genera were identified. Among them, the Navicula genus has the largest richness, and Achnanthes subsessilis and Nitzschia longissima were the dominant species in number.
