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') 100 read(3,110,end=300)ista,ndeps,stalat,stalon,id,im,iy 110 format(2i3,2f8.3,3i3) do 200 i=1,ndeps read(3,120)icast,ibott,pres,temp,salt,oxy,trit,sigt,he3,del3,che 120 format(2i2,f6.0,2f8.3,f5.0,3f7.2,f7.1,f7.2) 200 continue go to 100 c c ................................. c 300 close(unit=3) c c The program test.for has been succesfully used under both SUN OS v4.0 and Microsoft (MSDOS) v5.0 fortran compilers.

            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')
 100	read(3,110,end=300)ista,ndeps,stalat,stalon,id,im,iy
 110	format(2i3,2f8.3,3i3)
	do 200 i=1,ndeps
	    read(3,120)icast,ibott,pres,temp,salt,oxy,trit,sigt,he3,del3,che
 120	    format(2i2,f6.0,2f8.3,f5.0,3f7.2,f7.1,f7.2)
 200	  continue
	go to 100

The program test.for has been succesfully used under both SUN OS v4.0
and  Microsoft (MSDOS) v5.0 fortran compilers.

The variables read are

    STATION HEADER:
		ista	station number
		ndeps	number of depths to be read
		stalat	station latitude (N positive) in decimal degrees
		stalon	station longitude (W positive) in dec. degrees
		id,im,iy   station date (day, month, year)
    DEPTH RECORDS:
		icast	cast number
		ibott	bottle number
		pres	pressure in decibars
		temp	in situ temperature (deg. C)
		salt	salinity (PSU)
		oxygen	dissolved oxygen (uM/Kg)
		trit	tritium (T.U.) at time of station
		sigt	uncertainty in tritium (T.U.)
		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)].
