Notes -
DATA ACQUIRED:
&nbsp;&nbsp;
4,126 nautical miles of tracklines were run with the systems listed
above.
&nbsp;&nbsp;
Data consist of:
&nbsp;&nbsp;
1) GLORIA:
&nbsp;&nbsp;
a) 12 reels of 9-track digital magnetic tapes
&nbsp;&nbsp;
b) 12 reels of analog magnetic tapes
&nbsp;&nbsp;
c) 464 photo negatives, speed rectified side scan data
&nbsp;&nbsp;
d) shipboard monitor records, photo prints
&nbsp;&nbsp;
2) Airgun:
&nbsp;&nbsp;
a) 59 reels of analog magnetic tape
&nbsp;&nbsp;
b) shipboard monitor records
&nbsp;&nbsp;
3) 10-kHz Echo Sounder
&nbsp;&nbsp;
a) 2 sec. sweep shipboard records
&nbsp;&nbsp;
b) 0.5 sec. sweep shipboard records
&nbsp;&nbsp;
4) Navigation
&nbsp;&nbsp;
a) 50 Northstar cassette recordings from bridge
&nbsp;&nbsp;
b) 19 magnetic tapes from seismic lab
&nbsp;&nbsp;
c) 8 rolls printout from bridge
&nbsp;&nbsp;
d) 4 rolls printout from seismic lab
&nbsp;&nbsp;
e) 1 reel digital 9-track tape of Loran C plus satellite
fixes with water depths
&nbsp;&nbsp;
5) XBT:
&nbsp;&nbsp;
69 XBT recordings
&nbsp;&nbsp;
The cruise collected 3,731 nautical miles of data on the Continental
Slope in 17 days for the USGS, and in 2 additional days, collected 395
nautical miles for an IPOD site survey on the Mississippi Fan. The IPOD data
will be deposited in the IPOD data bank when processing is completed.
