This dataset contains a list of intertidal diatom species sampled at Gazi Bay (Kenya) in September 1991. Samples were taken from the upper 1 centimeter at each station using a Perspex insert tube (diameter 22mm). Identification of the diatoms was done on light- and electron microscopy. The data were digitized by VLIZ from the original report: Van Zele, M. (1992). Intertidale benthische diatomeeën van Gazi Bay (Kenya). Intertidal benthic diatoms of Gazi Bay (Kenya). MSc Thesis.
