Cooling of the southern high latitudes during the Medieval Period and its effect on ENSO

HVM, BM, 20/4/2016 Atlantic0235Sicre2011__RAPid 21-3K_alkenone Data are from the same location as the composite in Miettinen et al., (2012; diatoms, August SST, cores RAPiD-21-3K + RAPiD-21-12B ). The alkenone reconstruction from Sicre et al. (2011; RAPiD-21-3K) has higher resolution down core, and covers a wider range of the calendar year. The associated box core RAPiD-21-12B has an intact sediment surface and 210Pb measurements, however we did not apply the age model from RAPiD-21-12B to the RAPiD-21-3K alkenone record. Data younger than the youngest14C age (1730 CE) in RAPiD-21-3K were removed.

These are the original, not quality controlled data. O2kLR recommends only using the Quality controlled data.Dataset contains NaN values and datapoints whose chronology is not QC'd (near top of the core)
