Element data of potassium (K), calcium (Ca), titanium (Ti) and iron (Fe) of IMAGES core MD02-2576, supplement to: Kujau, Ariane; Nürnberg, Dirk; Zielhofer, Christoph; Bahr, André; Röhl, Ursula (2010): Mississippi River discharge over the last ~560,000 years -- Indications from X-ray fluorescence core-scanning.

The long term history of terrigenous flux to the Gulf of Mexico via the Mississippi River is hardly known. We here present geochemical and sedimentological data to approximate the varying Mississippi River sediment influx into the northeastern Gulf of Mexico (GoM) over the last six glacial-interglacial cycles (MIS 1 to 14). Our study is based on the IMAGES sediment core MD02-2576 that was recovered from the DeSoto Canyon and is located ~ 200 km south...

Antarctic Intermediate Water is, at present, a water mass that brings oxygen to intermediate depths throughout the Southern Hemisphere oceans. Models have suggested that intermediate waters had higher concentrations of oxygen during the last glacial period (Meissner et al., 2005, doi:10.1029/2004PA001083; Liu et al., 2002, doi:10.1029/2001GL013938), consistent with globally reduced denitrification (Galbraith et al., doi:10.1029/2003PA001000) and increased production of Antarctic Intermediate Water (Lynch-Stieglitz and Fairbanks, 1994, doi:10.1029/93PA02446). However, some palaeoceanographic reconstructions (Bostock et al., 2004,...
