A second set files were also collected during the cruise at one second 
intervals.  They are identical in content to the primary one minute files.

On October 23 (gmt), the ATHENA progam which collects and writes the files
kept reinitializing itself. At each reinitialization a new file was created, and
twice the new file which were created contained the wrong date attached to it. 
The files were checked for time and appeared that other than the loss of a few 
seconds of data the only major problem was the date. Prior to correcting the 
date, the original file was copied to *.*.org.

Due to requests for 'column' data, the one minute primary files were run through
a perl script, athena_column.pl. The output from the script are the *.*.dat 
files.  A header file, columnhdr, contains the information on what column 
contains which data. 

NARROW BAND ADCP (150ADCP)
Charlie Flaggs configuration was used, when the ship changed areas the 
ASHTEC and GPS information was lost, had to reboot the computer to get it 
back.

The 150 ADCP was only used during transits. Date and times are in GMT.

BROADBAND ADCP (300ADCP)
OC1998.cfg was the configuration file used to collect the data. Raw, processed
and nav data were all collected.

Due to conflicts with the Biomapper, the 300 ADCP was secured 26 Oct 98 0207 
gmt. The 300 ADCP was put back on line 26 Oct 98 at 2235 gmt for the remainder 
of the cruise.


CTD
Seven CTD stations were taken. The CTD worked well, although due to lanyard
hang ups and pylon pin sticking, several bottles did not fire properly.
