Subject: Wilkes Land Expedition 1985 Date: Wed, 15 Aug 2001 16:40:35 -0700 (PDT) From: "Theodore D. Foster (858) 822-2478" To: ricardo@nodc.noaa.gov, tfoster@seadog.ucsd.edu ~1640, 15 August 2001 Dear Ricardo, I have finally found all the data from the 1985 Wilkes Land Expedition. They are now ready to be "ftped" to your computer [or if I can remember how I did it, I could place it in an "anonyomous" location where you could retrieve it by "ftp"]. It was a lot of work to find these data and sort them out, but I had thought that they were sent to NODC years ago. The CTD winch the US Coast Guard used aboard their icebreaker POLAR STAR was a bit "flaky" near the end of this expedition and the Captain was totally inexperienced in icebreaking! I guess he was selected as the two POLAR-Class icebreakers were the largest ships the USCG had at that time and he was a senior Captain. He did not even wish to go into the ice at all and did not understand chart symbols (e.g "e.d." on a chart means "existence doubtful"). I had to threated to take my scientific party back to the USA to make him do anything at all! I do not know where all the bottle data are (since I am a Professor Emeritus of the University of California, Santa Cruz [NOT San Diego] they keep moving me from one office to another -- the latest move was in March (to make room for some "secretaries"). Everything is is still somewhere, but I do not know where. I am desperately trying to prepare my talk for the Mar del Plata meeting, but after I return from Argentina, I will try to find the remaining data. I am enclosing some instructions on how to interpret the data that are contained in the w85***.f files I will send you. They are all contained in the "tarred" and "compressed" file: wlex85data.tar.Z [3201590 bytes]. I also have these data in unformatted form that I could also send you, but I do not know if you could read them (they are all written using UNIX with a Sun computer). I chose file w85003.f to discuss below. The first line is the station "header": Lat. Long.

The p data were adjusted to agree with lab calibrations of the CTD. All the data were decimated to 1 decibars pressures. The data were NOT corrected or smoothed like I do now, but I no longer have any of the FORTRAN programs I used to gather or process these data so I would guess that perhaps the accuracies of these data are: pressures (+/-) 0.1 decibars temperatures (+/-) 0.005 degrees Celsius salinities (+/-) 0.005 psu oxygens (+/-) 0.05 ml/l The y63....f stations were an attempt to yo-yo the CTD at the shelfbreak at station w85063. Please send me an e-mail message at tfoster@seadog.ucsd.edu or call me at (858) 822-2478 if you have any questions about these data. Good luck!!! Best regards, Ted P.S. I will not be in my office Thurday or Friday this week, but I should be here Saturday and Sunday (sometime). TDF
