Sign of the whalers
December 10th - Day 12
We woke up to good news this morning. David (Mate) and Mikey (Deckhand) were on the four to eight watch morning when they spotted some radar interference. Radar interference can come from many different sources. This time, though, it looks like it's coming from another ship, and the only other ships in this part of the world belong to the whalers.
Radar has two parts - a transmitter and a receiver. The transmitter sends out pulses, and the receiver listens for how long it takes the pulses to bounce back. The longer a radar pulse takes to bounce back, the farther away the obstacle is.
Radar interference is when the pulses sent out by someone else's radar are picked up by your receiver. These pulses show up on the radar display as jagged noise.

Dave, Kieran and Wally try to puzzel out
the whalers' location. |
The important thing is that this radar interference means we're in the right area. Tomorrow we'll get the helicopter up, and try to pinpoint their exact location.
