The dataset includes speleothem U-Th ages used to reconstruct climate in southeastern Alaska during the past ~3,500 years. Speleothem WB-21-5-A was collected in Wishbone Cave...

Cl- and alkalinity were determined by visual titration with 0.1 M AgNO~3~ and 0.02 M HCl, respectively. NH~4~+ and PO~4~3 were measured spectrophotometrically (UV-2450, Shimazu)...

Authigenic neodymium isotopes measured on bulk sediment leachates and mixed planktic foraminifera from deep-sea sediment cores from the Nordic Seas and Arctic Ocean dated from...

The data set consists of magnesium (Mg), oxygen (O), and hydrogen (H) isotope signatures and Mg concentrations of monthly collected precipitation and daily snow samples. Samples...

This dataset contains molybdenum and uranium concentrations; uranium isotope compositions; pertinent major element concentrations; and total organic carbon contents of black...

Massive scleractinian corals provide unique opportunities to reconstruct past climatic and chemical changes in the ocean, where there is no additional information. Regular pH...

This dataset includes silicon isotopic compositions of δ30Si and δ29Si of 26 argillaceous sediment samples (including 20 bulk samples and 6 clay-fraction samples) from 13 major...

This data set reports neodymium (Nd) isotopic signatures at IODP Site 303-U1304 at the southern Gardar Drift in the North Atlantic to investigate changes in the deep water mass...
