A 125-ka record of South American precipitation and the role of the bipolar 2 seesaw during Dansgaard-Oeschger events
X-ray fluorescence data (Ti/Ca and Zr/Rb ratios) were obtained using the Aavatech XRF Core Scanner at University Kiel in two runs (10 kv, 750 mA, 10 seconds and 30 kv, 2000 mA, 20 seconds). Elemental intensities were measured every 1 cm between 0-18.83 m and 0.5 cm between 18.84-22 m (revised depth)...
