<font size=3>Greetings Bob,<br>
Thanks for providing the CTD seasoar data and very helpful
documentation.&nbsp; Your data shipment can be referenced in the future
by NODC Accession Number 0000005.<br>
<br>
As we work more closely with the data we will forward any questions that
might arise to you.<br>
<br>
Regards,<br>

&gt;Hello Doug,<br>
&gt;<br>
&gt; I have just transferred two compressed tar file to<br>
&gt;<a href="ftp://ftp.nodc.noaa.gov/" eudora="autourl">ftp.nodc.noaa.gov</a>,
inside the /pub/incoming/ directory.<br>
&gt;The files are called:<br>
&gt;<br>
&gt; w9605a.ctd.tar.Z<br>
&gt;and<br>
&gt; w9605a.csr.tar.Z<br>
&gt;<br>
&gt;<br>
&gt;Inside each of the tar files is a standard transimttal form:<br>
&gt;<br>
&gt; w9605a.ctd.txt<br>
&gt;and<br>
&gt; w9605a.csr.txt<br>
&gt;<br>
&gt;<br>
&gt;These transmittal forms are attached for your reference.<br>
&gt;<br>
&gt;<br>
&gt;The ctd files are standard ctd files from rosette casts;<br>
&gt;the csr files are ctd data obtained from continuous profiling<br>
&gt;with a SeaSoar while underway.<br>
&gt;<br>
&gt;If you have any difficulty with the files, please contact me<br>
&gt;and I will ftp the data to you again.<br>
&gt;<br>
&gt;Thanks for your help, and a few more sets will be coming your<br>
&gt;way soon.<br>
&gt;<br>

&gt; T1:(SN 1384) 28 March 1996<br>

&gt; C2:(SN 1738) 22 March 1996<br>
&gt;<br>
&gt;<br>
&gt; Data Processing:<br>
&gt; We compute lagged correlations between temperature and <br>
&gt; conductivity for each sensor pair, separately for ascending 
and<br>
&gt; descending profiles, and separately for two depth ranges: 10 
to<br>
&gt; 90 dbar, and deeper than 90 dbar, provided the segment contains
<br>
&gt; at least 180 scans. The fractional value of the lag at maximum 
<br>
&gt; correlation was determined by fitting a parabola to the cross-<br>
&gt; correlation values. Outlying lag values (obtained occasionally 
<br>
&gt; for data segments lasting &lt;10 seconds or having relatively low
<br>
&gt; correlations between T and C) were not used in processing the data.
<br>
&gt; The edited values of the alignment offset were applied sequentially
<br>
&gt; in reprocessing the 24-Hz T/C data. To reprocess data from depths
<br>
&gt; shallower than 10 m, we used the value determined from the
associated <br>
&gt; (ascending or descending) shallowest layer. Outlying lag values
<br>
&gt; that were not used were replaced with local estimates of the lag
<br>
&gt; based on nearby values.<br>
&gt;<br>
&gt; To correct the 24-Hz conductivity data for the thermal mass of
the<br>
&gt; conductivity cell, we used variable values for both the 
thermal<br>
&gt; amplitude and the thermal anomaly time constant depending on the
<br>
&gt; alignment offset:<br>
&gt;<br>
&gt; tows 1-2 (for T1-C1):<br>
&gt;  alpha = 0.0185 + 0.0000(lag)<br>
&gt;  tau = 7.150 + 1.340 (lag**0.5)<br>
&gt;    <br>
&gt; tows 1-2 (for T2-C2 at end of tow 1):<br>
&gt;  alpha = 0.0128 + 0.0000(lag)<br>
&gt;  tau = 7.148 + 1.329 (lag**0.5)<br>
&gt;    <br>
&gt; tows 3-6:<br>
&gt;  alpha = 0.0127 + 0.0027(lag)<br>
&gt;  tau = 7.150 + 1.341 (lag**0.5)<br>
&gt;<br>
&gt; These variable alpha and tau values represent the optimal<br>
&gt; thermal mass correction based on minimizing the area in<br>
&gt; T-S space of selected test hours for each set of tows.<br>
&gt;    <br>
&gt; The corrected and realigned 24-Hz temperature and conductivity data
are<br>
&gt; used to calculate 24-Hz salinity, and these are averaged to yield
one-<br>
&gt; second averages stored in hourly files.<br>
&gt;<br>
&gt; Successive hourly files of the reprocessed one-second average
data<br>
&gt; were joined to yield a single data file for each tow of the
survey.<br>
