Takahashi data base available
The LDEO (Takahashi) data base (Version 1.0) is now available for general
public use through CDIAC web page:
http://cdiac.ornl.gov/oceans/LDEO_Underway_Database/LDEO_home.html
More than 3 million measurements of surface water partial pressure of CO2
obtained over the global oceans during 1968 - 2006 are listed in the
Lamont-Doherty Earth Observatory (LDEO) database, which includes open ocean
and coastal water measurements. The data assembled include only those
measured by equilibrator-CO2 analyzer systems and have been
quality-controlled based on the stability of the system performance, the
reliability of calibrations for CO2 analysis, and the internal consistency of
data. To allow re-examination of the data in the future, a number of measured
parameters relevant to pCO2 measurements are listed. The overall uncertainty
for the pCO2 values listed is estimated to be ± 2.5 µatm on the average.
The data presented in this database include the analysis of partial pressure
of CO2 (pCO2), sea surface temperature (SST), sea surface salinity (SSS),
pressure of the equilibration, and barometric pressure in the outside air
from the ship's observation system. The global pCO2 data set is available
free of charge as a numeric data package (NDP-088:
http://cdiac.ornl.gov/oceans/ndp_088/ndp088.html) from the Carbon Dioxide
Information Analysis Center (CDIAC). The database is available as simple
ASCII data and metadata files, as an ODV collection, and via two search
engines: WAVES and LAS.
Thank you,
