The Institute of Marine and Coastal Research and the National Hydrocarbons Agency of Colombia have carried out environmental baseline research in hydrocarbon exploration blocks outside the Colombian Caribbean Sea, between 2008 and 2018. These investigations have generated taxonomic and ecological information of marine phytoplankton, obtained under different methods. The objective of the present work was to unify such information, certifying its veracity. For this purpose, data matrices were organized, refining the information, updating the taxonomy, categorizing it at the genus level, and standardizing abundance. Therefore, a database of oceanic phytoplankton of the Colombian Caribbean Sea is made available, with 5720 occurrences, with abundance added to 2440 of them. In general, this data set gathers information from 8 projects, 14 cruises, 12 exploration blocks, 120 stations, and 304 lots of mixed phytoplankton samples, where 135 genera distributed in 80 families, 45 orders, 9 classes, and 7 phyla were recorded. Abundance was standardized to cells per liter, obtaining a range between 9.6 and 7790.0 cel.L-1.
