PINT and the path to the perfect palaeointensity
Earth & Ocean
Andy Biggin's homepage
Welcome to the homepage of the
IAGA PINT Database. This database of absolute
palaeointensity measurements is maintained by
Andy Biggin in
the Department of Earth, Ocean and Ecological Sciences at the
University of Liverpool
in the U.K.
here to access the latest version
(2012.08) of PINT via a queryable interface.
to download the latest version of PINT (2012.08) as an MS Excel spreadsheet.
The PINT database was
most-recently described in Biggin et al. (2010, Eos, 91,
most-recently analysed in Biggin et al. (2009, Earth
Planets Space, 61, 9-22). Both papers are available from
and we would be grateful if you could cite at least the 2009 paper when you refer to the database in a published study.
You can find a presentation I recorded
June 2010 Santa Fe Meeting describing the current
database and outlining some ideas
Please watch this and let me
know the things you think would most improve PINT.
Background and information
aim of the PINT database is to catalogue all absolute
palaeointensity data with ages > 50 ka which have been
published in the peer-reviewed literature. The data is
provided at the cooling unit level or, in the case of large
intrusions, at the sampling site level. In some cases, the
data provided in the publication only allows averages of
multiple cooling units to be given. In such cases, this
should be apparent from the associated COMMENTS
Superceded results are
NOT removed from the database and duplicated measurements are NOT combined. If two or more mean measurements (produced
using different methods for example) are published for a
single cooling unit then each go into the database
separately. In all such cases, this should be apparent from
the associated entry in the COMMENTS Field.
The 2003 version of the IAGA absolute palaeointensity database
was described in detail by Perrin & Schnepp (2004; PEPI 147, 255-267). It was updated through late 2006 by Lisa
Tauxe (Tauxe, L. and Yamazaki, T, 2007. Paleointensities, in: Treatise
on Geophysics, Schubert, G. (ed.), vol. 5, Geomagnetism, 509-564, Oxford:
Elsevier Ltd.) and through early 2009 by
Biggin (with help from A. Roberts).
A new website for PINT with a
queryable interface was created in July, 2009. A big thank you to
for writing the code for the interface and assisting with its
formerly included in PINT 2003, with ages less than 50 kyr
are excluded from the latest version as these are now all included in the GEOMAGIA50
database. A copy of the 2003 database compiled by
Mireille Perrin and still containing the 0-50ka data is
An alternative version of this
database is maintained by the
Most PINT data are already in the MagIC
database and new data will continue to be uploaded.
Please let me
know if you spot any mistakes / omissions or have any suggestions
15th August, 2012:
227 new data from
14 references were added to the database and a number of corrections were made
(contact me if you would like details). Thanks go to Elliot Hurst (University
of Liverpool) for helping with this. Thanks also to Valera Shcherbakov for
providing the latest version of the
'BorokPINT' database (available from here)
to enable syncing.
3rd December, 2010:
178 new data from
11 references were added to the database and a number of corrections were made
(contact me if you would like details). Thanks go to Ashley Clarke (University
of Liverpool) for doing this update as part of his MESci final year project.
29th July, 2009:
145 new data from
11 references were added to the database. Thanks go to Andy Roberts (University
of Liverpool) for help with this.
10th June, 2009: 42 new data from 3
references were added.
It was realised that the data carried over
from PINT03 in the AGE, DAGE, SLAT, and SLONG fields were truncated after
1 decimal place (thanks to Leah Ziegler for pointing this out). This was rectified.
For the sake of consistency with the rest
of the database, a number of values in the 'DF' field known to record
estimates of the standard error of the mean palaeointensity were
replaced with a calculated sample standard deviation (the more usual
'error' quoted with mean palaeointensity estimates). This change was made
to the 578 records associated with reference numbers 2,5,6,7,8,9,10,11,15,16,17,76,84,85,86,87,114,138,153,154,172.
15th August, 2008: A comparison with
the 'BorokPINT' database (available from here)
led to the addition of 217 new data from 14 references.
