Ascophyllum nodosum segment biomass

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). The average biomass (dryweight, dw) of segments of different age was quantified.

本数据集为迪斯科（Disko）大型藻类生长基础监测数据。数据集包含2012年至2021年的年度采样数据：研究人员于潮间带中区的泡叶藻（Ascophyllum nodosum）种群中随机采集20株处于活跃生长状态、呈浅棕色的嫩梢，以测定其嫩梢的年度生长量。将采集到的嫩梢在第3个泡囊下方截断后，切割为若干独立切段/梢段：其中包含第1个泡囊的外侧嫩梢对应0龄组，第1个泡囊下方且包含第2个泡囊的切段对应1龄组，第2个泡囊下方且包含第3个泡囊的切段对应2龄组。最终对不同龄期切段的平均生物量（干重，dryweight, dw）进行了定量测定。
