700 Years of Ice Core Major Ion Chemistry Data from Law Dome, Antarctica

A compilation of 700 years of Law Dome major ion chemistry data, recorded from 3 ice cores; DSS97, DSS99, DSS main.This work was completed as part of ASAC project 757 (ASAC_757).Species which have been the subject of publication and could be made available after consultation:Species, Period (AD), Resolution, CommentsSO4, 1301-1995, Fine (full) NO3, 1888-1995, Fine (full), full 700 year annuals used by Mayewski solar-polar paper in preparation(Ca,K,Mg,Na,NO3,SO4,Cl), 1301-1995, AnnualMSA, 1841-1995, AnnualNa, 1301-1995, Fine (full)Na, 1301-1995, Annualnon-sea-salt SO4 (nss SO4), 1301-1995, Annual, Uses a calculated SO4 fractionation % to correct the seawater ratio (due to fractionation at the source). Corrected ratio 0.087 (using uEq/L). There are still 'negative' values and some zero's - this data has not been 'cleaned'. If you need to use this, please contact Mark Curran for help.An updated copy of this dataset was submitted to the Australian Antarctic Data Centre in early July of 2012.
