In siddition, some seismic reflection shooting was carried out, occas- 

 ional air saniples were taken, gravity was measured in ports of callj 

 rocks and biological specimens were collected in ports of callj and large 

 organisms were dip=netted at light lures on most night stations. 



The second Scripps cruise, called LUSIADj is also being carried 

 out by the RA ARGO, according to the following itinerary?
