These data are made freely available to the public and the scientific community
in the belief that their wide dissemination will lead to greater understanding 
and new scientific insights.  The availability of these data does not 
constitute publication of the data.  We rely on the ethics and integrity of the 
user to assure that AOML receives fair credit for our work.  Please send 
manuscripts using this data to AOML for review before they are submitted for 
publication so we can insure that the quality and limitations of the data are 
accurately represented.

*********************** Reciprocity Agreement *****************************
* [Adapted from NOAA Earth System and Diagnostic Laboaratory (ESDL) *
************* Carbon Cycle Greenhouse Gasses (CCGG) web site] *************

Use of these data implies an agreement to reciprocate.  Laboratories making
similar measurements agree to make their own data available to the general
public and to the scientific community in an equally complete and easily 
"accessible form.  Modelers are encouraged to make available to the community, "
"upon request, their own tools used in the interpretation of the AOML data,"
namely well documented model code and any additional information necessary for 
other scientists to repeat the work and to run modified versions.

Comments:

On 30 July, 2006, some improvements and maintenace was done on the system
while the Skogafoss was in Boston.
 
The GEMS paddlewheel water flow meter was replaced by Proteus water flow 
meter (#0504SN2).  The frequency output of the GEMS meter had been monitored 
by a SuperLogic 8080 module.  That module was removed from the system.  
The (0-5 vdc) output of the Proteus meter was wired to channel 3 on the SuperLogic 
8017 module.  New calibration coefficients for the Proteus meter were put in the 
'cal.dat' file.
Both PermaPure naphion dryers were replaced.  The atmospheric pump is still not 
delivering more than 50 ml/min flow; however, with sequential samples there is enough
flushing of lines for some acceptable analyses.
A digital timer was put between the power transformer and the deck box.  It was set
to turn the power off for one minute every day.  This resetting of the Iridium modem 
has been found to be necessary if the modem is being left on continuously for days.
