Ascophyllum nodosum segment length

Nuuk basis monitoring of macroalgae and fauna – population dynamics of knotted wrack (Ascophyllum nodosum). Ascophyllum nodosum segment length. 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 measured to the nearest mm. From 2015, additional sampling of tips in the mid tidal zone from populations in two other sites in Kobbefjord were also included.努克基地大型藻类与动物群监测：泡叶藻（Ascophyllum nodosum）种群动态及节段长度数据集。本数据集涵盖2012年至2021年的年度采样工作：于每个潮带（高潮带、中潮带、低潮带）的泡叶藻种群中随机采集20株顶枝（处于活跃生长状态、呈浅棕色），用于测量顶枝的年度生长量。采集的顶枝在第3个气囊下方剪断，随后被切割为独立节段/顶枝区段：包含第1个气囊的顶尖区段为第0年区段，第1个气囊下方且包含第2个气囊的区段为第1年区段，第2个气囊下方且包含第3个气囊的区段为第2年区段。每个节段的长度均精确至毫米级。自2015年起，数据集还补充纳入了科布峡湾（Kobbefjord）另外两个站点的中潮带泡叶藻种群顶枝采样数据。
