2008-2017 Globigerinoides ruber Sediment Trap Data Collected from the Gulf of Mexico

This data release includes results of a high-resolution (1–2 weeks) and long-term sediment trap time series collected from the northern Gulf of Mexico. This dataset allows for a detailed assessment of the seasonal distribution, size, morphological variability and geochemistry of co-occurring pink and white chromotypes of the shallow-water foraminifera, Globigerinoides ruber. The flux of both chromotypes is highly correlated, and both represent mean annual conditions in the marine surface mixed layer. Under modern climatic conditions in the Gulf of Mexico, USGS researchers found no significant offset in the Magnesium/Calcium (Mg/Ca) and delta Oxygen-18 (d18O) of co-occurring pink and white G. ruber (Richey and others, 2019). Furthermore, findings show the d18O and delta Carbon-13 (d13C) among the two morphotypes (sensu stricto and sensu lato) of both pink and white G. ruber to be indistinguishable. The test size distribution within the population varies seasonally, with the abundance of large individuals increasing (decreasing) in summer (winter).
