Excel file containing CPR data for area 51N to 60N, -3W to 10E, 2000 to 2019, sample level data (each sample being 1 row, equating to approx. 10 nautical miles of tow, 3m3 of filtered seawater), for Total Diatoms and Total Dinoflagellates. For each taxa, values indicate abundance (according to standard CPR methodology, see Richardson et al. 2006, Prog in Oceanog 68. 27-74), values of 0.001 indicate presence only, zero values are absence of taxon. The excel file consists of samples in rows, with the following information in columns - A: sample id B:midpoint of sample latitude in decimal degrees C:midpoint of sample longitude in decimal degrees D:midpoint of sample local date and time E:sample year F: sample month G: Phytoplankton Colour Index (and indicator of primary production) H: Total Diatoms I: Total Dinoflagellates
