| contents | We performed geochemical and sedimentological analyses on a 12.2 m long, radiocarbon-dated sediment core collected from Wide Channel (50°S; Chile) to reconstruct fluctuations of the marine-terminating HPS19, Penguin and Europa glaciers, located along the western side of the Southern Patagonian Icefield. The JPC42 sediment core was collected with a Jumbo Piston corer onboard the RV/IB Nathaniel B. Palmer in July 2005. An additional 1.5 m long Kasten core (KC41) was retrieved to sample the sediment-water interface. Both cores were scanned on an ITRAX XRF core scanner at WHOI in August 2008 and then sampled in 2 cm thick slices (ca.10 cm³) every 10 cm at the Marine and Geology Repository of Oregon State University in February 2021. Samples were freeze-dried at Ghent University, and all discrete analyses were performed at a 10 cm interval, except for CaCO3 in the lower 5.9 m of the core, which was analyzed at a 20 cm interval. |
