Diatom and dinoflagellate populations from various pier stations along the western North American coast were enumerated by W. E. Allen from 1917 through the mid-1940s. Most of the original data sheets have been archived by the Scripps Institution of Oceanography (SIO) Library. From these original records, weekly (plus some hourly and some daily) diatom and dinoflagellate species abundances from SIO, Oceanside, Port Hueneme, Pacific Grove, Farallon Islands, and Scotch Cap piers for the period 1917 - 1939 have been digitized into a format that can be read by most current computer operating systems. This Reference Series provides these data on the CD titled W.E. Allen's Phytoplankton Species Time Series Data (1917-1939) from the North American Pacific Coast.
