Ascophyllum nodosum segment length

Disko basis monitoring of macroalgal growth. The dataset consist of annual (2012-2021) sampling of 20 Ascophyllum nodosum tips (actively growing, light brown), randomly sampled in the population in the mid tidal zone for the purpose of measuring annual tip growth. The tips were cut below the 3rd bladder and then cut into seperate segments/tip-sections (Outer tip incl. 1st bladder = year 0, below 1st bladder incl. 2nd bladder = year 1, below 2nd bladder incl. 3rd bladder = year 2). Each segment was measured to the nearest mm.

本数据集为迪斯科岛（Disko）大型藻类生长基础监测数据集。数据集包含2012年至2021年的年度采样工作：在潮间带中区的种群中随机采集20份处于活跃生长状态、呈浅棕色的泡叶藻（Ascophyllum nodosum）顶枝，用于测定其年度顶枝生长量。采集得到的顶枝先在第3个气囊下方剪下，随后被切割为独立的节段/顶枝区段：包含第1个气囊的外顶枝对应第0年样本，第1个气囊下方且包含第2个气囊的区段对应第1年样本，第2个气囊下方且包含第3个气囊的区段对应第2年样本。所有节段均以毫米为单位进行精确测量，精度至1mm。
