Peter,

I got a call from John Sibunka yesterday with some good news and
some bad.  (Sorry for the "classic" joke.)  The good news is that
they are actually starting to look at their data, and using the data
system to get at the event log data.  The bad news is that they may
have found some "bad values" in the event log from your cruise.

The immediate action is to verify the positions of the stations they
mention (see below) and make the necessary corrections.  Since this
is your cruise, I wanted to work with you on this.

The longer term issue is "we need a new protocol".  Namely, a
protocol defining how updates/corrections should be communicated and
accomplished.  My philosphy would be that the responsible scientific
investigator be contacted, with a CC to me, whenever a data problem
is detected.  I want to know in case the problem is "large enough"
that I should make a larger audience aware of the problem and the
solution.  I also may need to know, since I may be serving the data
rather than the SI (as is the case with the event logs).  In this
latter case, I need to clear any changes with the responsible SI
before I make any changes.

Your thoughts on this would be appreciated.

Cheers, Bob

     Hi Bob,
     
     This is a follow up on our telephone conversation this morning 
     concering station position corrections to the event log for cruise EN 
     261.  Wally and I found (so far) the following four stations to be in 
     error: standard stations # 3, 6, 7, 11.
     
     These positions are in decmial degrees.
     
     Sta. # 3  is   40.6267
        Should be   40.5283
     
     
     Sta. # 6  is  -68.0252
        Should be  -67.7483
     
     
     Sta # 7   is  -68.311
        Should be  -67.311
     
     Sta # 11  is  -68.4257
        Should be  -67.96
     
     When Wally did a computer plot of the cruise stations based on the 
     positions from the event log, station # 3 appeared off and is by ~6 
     miles.  The "ground truth plot" is based on the proposed station 
     positions as found in the Chief Scientist manual for 1995.  Also 
     stations # 6, 7, 11, plotted a whole degree of Longitude off.
     
     That's all for now.
     
     John
