Fourteen coring stations were occupied, with core material recovered on every attempt.  Cores were not opened on board, but subsequent laboratory work indicates that the recovered sediments should allow most of the cruise objectives to be addressed.  Seabed photography and scatterometer tests were limited by the failure of the conducting cable.  However, initial tests of the scatterometer were encouraging. 12TABLES  Table 1.

Passage to Santa Cruz, Tenerife  SUMMARY  OF RESULTS This was a short but successful cruise.  Fourteen coring stations were occupied, with core material recovered on every attempt.  Cores were not opened on board, but subsequent laboratory work indicates that the recovered sediments should allow most of the cruise objectives to be addressed.  Seabed photography and scatterometer tests were limited by the failure of the conducting cable.  However, initial tests of the scatterometer were encouraging. 12TABLES  Table 1.
