In addition, some seismic reflection shooting was carried out, occasional 

 air samples were taken, gravity was measured in ports of call, rocks and 

 biological specimens were collected in ports of call, and large organisms 

 were dip- netted at light lures on most night stations. 



The second Scripps cruise, called LUSIAD, was also carried out by the R/V
