Summary
Abstract: 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, Comments
SO4, 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, Annual
MSA, 1841-1995, Annual
Na, 1301-1995, Fine (full)
Na, 1301-1995, Annual
non-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.

Quality
The cores were dated using multi-species annual layer counting and combined into one record (see Palmer et al., JGR 106, 2001)

The dating scale is known as LD1 (see van Ommen et al., Annals of Glaciol., 39, 2004, in press)

This dating scale has been updated in May 2007 to add one year around Tambora region - it is the latest and best dating as of September 2010

The dates provided in temporal coverage are approximate only and cover the span of years over which the ice cores were collected.
