Population structure and dynamics of Ascophyllum nodosum were analysed in late summer (August/September) 2012-2019 across ten permanent plots (0.25x0.25 cm) situated in the mid-tidal zone of Kobbefjord. Population biomass was non-destructively estimated each year by measuring the length from the hol...
