Many hours were required for each deployment and retrieval of the sources, primarily because of the time-consuming manual task of attaching massive fairings, segment by segment (as shown in Figure 4) to the supporting umbilical cable. Once the string of sources was deployed it was difficult to recover quickly, so the weather played a large part in determining the success of the experiment. Initially the weather behaved and the sources performed admirably. Several receiving stations reported solid receptions. However, as the seas grew larger, one by one the sources failed in the extremely heavy conditions, but not before all signal types had been thoroughly exercised.
