Dear Tim,
I could pool up most of the data I used in my papers.
Please find the attached zip files.
There are four cruises- antarctic, sk110, sk119, and sk120.
SK is for Sagar Kanya ORV.
SK 110 and 119A are merged files.
The antarctic CTD header infor is given as a word file.
Please note that all xbt do not have corresponding match-up CTD.
You have to pool up the matchups from the date and position of CTD and XBT headers.

If you have any difficulty in understanding, Pls. let me know.

Since I have done these work nearly 10 years back, I am not able to
locate the match ups pairs exclusively.

best regards, Pankaj
