Hole:  504B		Leg:  83		Location:  Costa Rica Rift (equatorial NE Pacific)
DLIS File:  504B_83_1.dlis        ( LDEO Inv. #  6/NGDC Inv. # SLOG052-54/56  and 58-60)        Data recorded by Schlumberger.
NGDC Inv. # SLOG057 Original 9-track tape had parity errors and was not included among tapes received from DSDP.
NGDC Inv. # SLOG055 is given as a 504B tape. The depths, however, are shallower.
