                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

     300	close(unit=3)

    c
    
    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)].
    
        
        The data reported here are the result of the work of a number of
    people (both present and past) in the Helium Isotope Laboratory.  They are
