<li> These data are accessed under the the GLOBEC
homepage-->data-->process-->{year}-->alongtrack

<li> These are single ascii files per cruise with several variables
merged to one minute (interpolated) time steps. The user should be aware of
the availability of the unmerged "raw" data at
<a href="http://www.wh.whoi.edu/~albscs">
http://www.wh.whoi.edu/~albscs</a>
(for Albatross data) if they want the actual data which, for some
sensors/variables, was recorded as frequent as every 5 seconds and by more
than one instrument.
Contact <a href="http://globec.whoi.edu/globec-dir/contact_j_manning.html">Jim
Manning</a> for authorization to access these data.

<li> The first column is the time stamp which, for Albatross convention, is
"yrday1_local" which means, for example, that a time of "1.5" represents
local noontime on Jan 1st. Note that the "Albatross convention" may change
so the user must pay attention to the time stamp variable name in the
future cruises.

<li> I have been processing Albatross alongtrack data on an "as
requested" basis so just let me know when you want a particular cruise that
is not already posted.  

<li> We all understand this data (shipboard temp, salt, wind, etc.) should
be treated as uncalibrated records and <b>should not be used other than
exploratory purposes</b>.

<p>

Note: I have been delayed in getting this data on-line because I am
not happy with my "corrected" wind (with ships motion removed) and,
I am still not comfortable with posting the corrected wind so I
have added a comment on the fact that it is questionable. I have notified
the OCEANUS SSSG people about this problem. In the meantime I suggest
that any one interested in wind for these periods use the NOAA buoy
winds instead.
