Tha magnetic data were acquired primarily during the SBP and MULTIBEAM runs. We had some difficulty in data acquisition during heavy traffic conditions and when approaching the coastline, when we were forced to partially or fully recover the instrument. This was noted on the Observer's Log and will help in final processing sequence. As shown in Fig. 34, the data depicts clearly the (mostly day/night) variations of the signal along the lines and call for the corrections with the Istanbul Observatory data. The crude processing of the raw data, however, show that tha quality of the data is rather good.
