Ascophyllum nodosum segment biomass

Nuuk basis monitoring of macroalgae and fauna – population dynamics of knotted wrack (Ascophyllum nodosum). Ascophyllum nodosum segment biomass. The dataset consist of annual (2012-2021) sampling of 20 Ascophyllum nodosum tips (actively growing, light brown), randomly sampled in the population in each of the tidal zones (upper, mid, lower) 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 dried at 60 degrees Celcius and weighed. From 2015, additional sampling of tips in the mid tidal zone from populations in two other sites in Kobbefjord were also included.努克（Nuuk）基地大型藻类与动物群监测——泡叶藻（Ascophyllum nodosum）的种群动态。本数据集包含泡叶藻的切段生物量数据。数据集涵盖2012年至2021年的年度采样工作：在每个潮带（高潮带、中潮带、低潮带）的种群中随机采集20株泡叶藻的顶枝（处于活跃生长状态，呈浅棕色），用于测定年度顶枝生长量。采集的顶枝在第3个气囊下方剪断，随后被切割为独立的切段/顶枝段：包含第1个气囊的外顶枝为第0年样本，第1个气囊下方且包含第2个气囊的区段为第1年样本，第2个气囊下方且包含第3个气囊的区段为第2年样本。所有切段均在60摄氏度条件下烘干并称重。自2015年起，研究人员还额外采集了科布峡湾（Kobbefjord）另外两个站点的中潮带种群的顶枝样本。
