CDIAC has added an archive of ocean surface water radiocarbon data derived
from surface dwelling, reef-building hermatypic corals, which have been shown
to be reliable archives of ocean Σ14CO2:
http://cdiac.ornl.gov/oceans/Coral_C14.html
All samples were prepared and analyzed at the Center for Accelerator Mass
Spectrometry (CAMS), Lawrence Livermore National Laboratory, and all data
have been "age-corrected" to produce an accurate surface water 14C historical
reconstruction. The eight data sets presented in this archive have been
previously published, and all cover the latter half of the 20th century.
Users are encouraged to take advantage of the primary references to place the
results in a more detailed dynamic context.
This data are great addition to the previously published by CDIAC "Carbon-14
Measurements in Surface Water CO2 from the Atlantic, Indian and Pacific
Oceans, 1965-1994. By Reidar Nydal (NDP-057A)":
