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.
