From: "Michael Crane" Subject: CTD Data from Miami To: Steven Rutz CC: Joseph Stinus Steven, Don Olson from the University of Miami has made his CTD data available from the US Navy cruise in the Arabian Sea region. Subject: Naseer CTD files (fwd) Date: Tue, 17 Jul 2001 11:36:22 -0400 (EDT) From: Don Olson To: michael.crane@noaa.gov Michael, Here is the ftp address for the files. I am still trying to find some of the background documents for the program and the ONR contract numbers etc. Don Forwarded message: > From: Geoff Samuels > Subject: Naseer CTD files > To: dolson@rsmas.miami.edu > Date: Mon, 16 Jul 2001 11:53:59 -0400 (EDT) > > Don, > Below is a summary of where the CTD files are, what they are and > how they can be accessed. > > ------------------------------------------------------------------ > > The Naseer CTD files are on the ftp server "abui.rsmas.miami.edu". > > Naseer1 files are in the ftp directory "pub/geoff/naseer/naseer1". > Naseer3 files are in the ftp directory "pub/geoff/naseer/naseer3". > Naseer4 files are in the ftp directory "pub/geoff/naseer/naseer4". > Naseer5 files are in the ftp directory "pub/geoff/naseer/naseer5". > > Each subdirectory has a file summarizing the dates, times and > positions of each cruise. > > These position files are named: > "pub/geoff/naseer/naseer1/n1posn" > "pub/geoff/naseer/naseer3/n3posn" > "pub/geoff/naseer/naseer4/n4posn" > "pub/geoff/naseer/naseer5/n5posn" > > Below are the first 10 lines of file n1posn.
