The Saalian was one of the largest glaciations during the Quaternary with an ice sheet extending considerably wider into the Eurasian continent than during other glacials. Orbital variations caused the ice sheet to switch between growing and shrinking. The partial retreat of the ice sheet and meltwater discharge resulted in global sea-level rise and increased lake levels of inland seas with broader environmental implications. During Marine Isotope Stage 6 (MIS 6), meltwater entered the formerly enclosed Black Sea at least twice as documented in a d18O record from Anatolian speleothems. Here we present a sedimentary record from the Black Sea "Lake" covering MIS 6 and provide evidence for three meltwater periods coinciding with insolation maxima (BSWP-6-1: 180-167 ka BP, BSWP-6-2: 160-145 ka BP, BSWPII: 133-130 ka BP). While d18Oostracods and Sr/Caostracods point to pronounced meltwater supply and decreasing salinity, 87Sr/86Srostracods shed light on meltwater sources and pathways. During all three periods, ... : Supplement to: Wegwerth, Antje; Dellwig, Olaf; Wulf, Sabine; Plessen, Birgit; Kleinhanns, Ilka C; Nowaczyk, Norbert R; Jiabo, Liu; Arz, Helge Wolfgang (2019): Major hydrological shifts in the Black Sea “Lake” in response to ice sheet collapses during MIS 6 (130–184 ka BP).
