Species and habitats - Platichthys flesus - All ages - Mean abundance in October, standard deviation maps during CGFS (1988-2009)

Biologic data have been expressed in abundance (numbers or density values (nbr/km²)) and always required to be log-transformed using a log10(x+1) transformation. Abundance mean (mean) and standard deviation (st) have been calculated.生物数据常以丰度形式呈现，涵盖数量或密度值（单位：个/平方千米），且均需通过log10(x+1)变换进行对数转换。已计算得到丰度均值（mean）与标准差（st）。
