North American and Pacific inputs in the Nd and Sr isotope Pleistocene record from the western Arctic Ocean sediment core P1-93AR-P23 ...
Sediment coreP1-93AR-P23 was collected in 1993 from the Northwind Ridge, western Arctic Ocean. Sediments were leached in 2011 to remove authigenic fractions. The residual leached sediments were digested using a microwave system. Strontium and neodymium were isolated using column chemistry, and analy...

Summary: | Sediment coreP1-93AR-P23 was collected in 1993 from the Northwind Ridge, western Arctic Ocean. Sediments were leached in 2011 to remove authigenic fractions. The residual leached sediments were digested using a microwave system. Strontium and neodymium were isolated using column chemistry, and analyzed by multicollector ICP-MS. The data span the time period from the late Pliocene to the most recent glacial interval, including the mid-Pleistocene transition where glacial cycles shifted from a dominant ~41ka cyclicity to a ~100ka cyclicity. ... |
