Abstract:

This dataset consists of species-level benthic foraminiferal assemblages identified from three sediment cores collected aboard the R/V Justo Sierra cruise JS0815 in the southern Gulf of Mexico from 2015-08-05 to 2015-08-06. The dataset includes the depth increment relative to sediment surface and individuals identified (count). The main objective of cruise JS0815, led by Chief Scientist Dr. David Hollander, was to determine the impact and recovery of benthic infauna and epifauna related to subsurface petroleum releases in the southern Gulf of Mexico. Cruise JS0815 extended from 2015-07-30 to 2015-08-09.
