Recent Quaternary carbonate island sediment preservation along low-latitude coastal regions, such as in the Bahamas, contain sediment sourced from adjacent marine environments during interglacial intervals. During these interglacial intervals, denoted by odd-numbered Marine Isotope Stages (e.g., MIS 1, 3, 5), sea levels are at a highstand relative to glacial periods (e.g., MIS 2, 4, 6). Samples analyzed in this study focused on deposition following the Last Interglacial (LIG) highstand, particularly the relatively less-understood MIS 5a, defined in this region as the Whale Point Formation (WPF) (Kindler and Hearty, 2022). Here, we present laser diffraction particle size analyses (PSA) from a Beckman Coulter LS 13 320 XR instrument located in the Bascom Laser Diffraction Sedimentology Laboratory in Reston, VA. The PSA data represent aeolianites from the windward coastlines of Great Abaco, Eleuthera, San Salvador, and Long Island from MIS 5 and MIS 1. The overall distributions are unimodal, however, for Eleuthera, distinct bimodal distributions were observed.
