Diatoms in surface water at time series station Helgoland Roads, North Sea, in 1906


The dataset corresponds to the diatom plankton count recorded from 1906 in Helgoland Roads. The original data set was handwritten in paper sheets to be found at the AWI library collection. Original counts were recorded in German as: Selten (s), Vereinzelt (v), Nicht selten (n.s.), Häufig (h), sehr häufig (s.h.) and massenhaft (m). Data was digitized and converted into an English scale and then into numerical data as follows:Not present (-): 0selten (s) - rare (r): 1vereinzelt (v) - occasional (o): 2nicht selteen (n.s.) - not rare (n.r): 3häufig (h) - common (c): 4sehr häufig (s.h.) - very common (v.c): 5massenhaft (m) - mass bloom (m): 6 For Auliscus sculptus on 1906-05-11 a count of (18x) was found in the original dataset Cells left in blank correspond to species not found by the time, but encountered later the year
