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.

努克基地大型藻类与动物群监测——绳藻（Ascophyllum nodosum）种群动态：绳藻分段生物量数据集。本数据集涵盖2012年至2021年的年度采样工作：在各潮带（高潮、中潮、低潮）的绳藻种群中随机采集20株活跃生长、呈浅棕色的顶枝，用于测定顶枝的年度生长量。采样时于第3个气囊下方截取顶枝，随后将其切割为独立分段/顶枝段：外顶枝（含第1个气囊）对应0年组，第1气囊下方包含第2气囊的区段对应1年组，第2气囊下方包含第3气囊的区段对应2年组。所有分段均在60摄氏度条件下烘干并称重。自2015年起，额外纳入了科布峡湾（Kobbefjord）另外两个位点的中潮带绳藻种群的顶枝采样样本。
