Helium tritium merge file: nas_he3-tu.orig.Z from WHOI P.I.: W.J. Jenkins
Received from J.L.Reid office Jan 19, 2006.
Tritium merge file: nas1-7.c14.orig.Z Believed to be from Univ. of Miami; P.I.: H.G Ostlund
Received from J.L.Reid office Jan 19, 2006.
Note with data says: "TU in old scale at time of sampling"
Tritium samples taken by both WHOI and U. of Miami. WHOI values used if available.
U. of Miami values used if WHOI values not available. If both WHOI and U. of Miami
tritium values available for the same sample the WHOI value is flagged "6" and the
U. of Miami value is shown on the following list:

WHOI Helium Isotope Lab
Data Release #3.0 August 31, 1989
Tritium and 3He from TTO-NAS and NATS 1981
Dear Colleague,
The files on this disk (TTO.DAT and NAT.DAT) are a listing of
tritium, helium and hydrographic data taken on two expeditions which
took place in the summer of 1981. The TTO North Atlantic Survey took
place on the KNORR on seven legs with a variety of chief scientists
(see the data report published by Scripps Institution of Oceanography,
ref SIO No. 86-15). The NATS (North Atlantic Tracer Section) data
(AT-109, legs 1-3) were taken with C.Wunsch, H.Stommel and D.Roemmich
as chief scientists. We are indebted to all for their help. This
work was supported by the National Science Foundation, grants No.
OCE79-21378 and OCE81-17998. You are free to use this data as you see
fit, but an acknowledgement of its source would be appreciated in any
resulting publications.
There are a total of 3235 tritium and 2893 helium measurements.
The data are organized as simple ascii files with two kinds of records
in a repeating pattern: a station header record, followed by a number
of depth records. Ancillary hydrographic information is included for
your convenience only, and we make no claim as to its accuracy. Cast
and bottle numbers are included to permit referencing the actual
hydrographic data released by the PACODF group. We present the
helium-3 data in two "units" for use at your own discretion. Null
values are indicated as -99. We have made every attempt to ensure that
there are no errors in the data (eg due to mis-labelling), but if you
find any "fliers", please notify us (telemail W.Jenkins) of the cast
and bottle number and what the problem appears to be, and we will
investigate. Don't forget to include the data release number.
The data can be read by the following fortran statements (contained in the
file "test.for"):
open(unit=3,file='TTO.DAT',status='old')

he3 excess helium-3 (T.U.)*
del3 helium isotope ratio anomaly (permil)**
che helium concentration (ncc/g)***
* the excess helium-3 is computed according to Jenkins (1987).
Uncertainty is .035 T.U.
** relative to the atmospheric ratio. Uncertainty is 1.5 permil.
*** uncertainty is 0.1 ncc/g [ncc = 10^-9 cc(STP)].
