2008–2020 Planktic Foraminiferal Assemblage Data From Subtropical Atlantic Ocean Sediment Traps

Sediment trap time series studies collect data on planktic foraminiferal flux, assemblage composition, and geochemical responses to environmental variables, which are used in paleoceanographic research. This data release presents weekly-to-monthly resolution foraminiferal assemblage data from a long-running sediment trap study (2008–2020) in the northern Gulf of America (nGulf; 27.5° N and 90.3° W). A summary of the species composition (29 total) is provided, with raw counts and size distributions. Flux data (tests m-2 day-1) for the fifteen most abundant species of extant planktic foraminifera, which account for 98% of the total flux (tests m-2 day-1), are also calculated. This data release compiles data previously published in Reynolds and Richey (2023) from the 2008–2014 time interval with additional data through completion in 2020, as well as new information on the Gulf sediment trap time series (GMT). For more information, refer to the associated journal article by Richey and others (2026).
