Notes ---
REPLACES MGD77 FILE SENT TO NGDC (SEP86) WHICH CONTAINED DEPTH ONLY. DEPTHS
NOT PROCESSED (NO FUNDS). NO BEG/END TIE POINTS BUT STILL METER READING AVAIL.
IN SAN DIEGO. 3.5KHZ DEPTH RECORDED 24JUL-4AUG. NO U/W DATA COLLECTED
2000Z/25JUL-0700Z/28JUL86 (USSR WATERS). SEISMICS RECORDED DIGITAL ONLY FEW
HOURS. REMAINDER ANALOGUE DATA. NGDC has multibeam bathymetry, however GEODAS
tracklines may not exactly correspond to the multibeam data.
