Annualized Summer Sea Salt From the Law Dome Ice Core Chemistry Record, 1000-2009

This data set is the logged, annualised summer sea salt (December to March, DJFM) concentrations from the Law Dome ice core chemistry record, spanning 1000-2009 AD (dates apply to the year of JFM, so e.g. 1980 is an average of Dec 1979 and Jan-Mar 1980). The data are compiled from numerous ice cores drilled at the Law Dome site sequentially since 1987, and chronologically dated using volcanic horizons and annual layer counting.

The cores used are (chronologically from oldest data to newest):

DSS Main DSS97 DSS0102 DSS0809 DSS0910

The dataset has 37 'missing' summer values in instances where insufficient ice core material was available. These missing summers have been filled using linear interpolation.

This work forms part of Australian Antarctic Science (AAS) project no. 757.

The record was published as an ENSO and eastern Australian rainfall proxy record in:
