he wind picked up a little today and the ocean was a little rougher than it had been lately. The only pod we had been able to find was way off in the distance. Our data came out ok, but I am pretty sure there were a few errors on the map some where.Underwater noise pollution is the topic of the lecture today. Team 5 was giving us the discussion notes and leading our debating. We learned that before humans started exploring the seas the clarity at which sound could travel could be measured in thousands of miles as compared to now in hundreds of miles. We learned that boats, sonar, even events occurring on land were effecting the level at which sound traveled in the water. A few species adapted to a new frequency of communication since their old one was masked by boats or other sounds.Jan. 19 LFA Sonar the navy’s evil aquatic weapon?Day off for team TG today gives us extra time to work on any thing we forgot last night. I plan on going to the beach to do some swimming and then maybe see some more tourist spots. As long as I am back for lecture at 7:00.Lecture is given by team 6; the topic is LFA Sonar and its effect on whales. LFA sonar operates by emitting an ultra low frequency sound at high decibels. When low sounds are amplified and sent out into water they can cause severe hemorrhaging in any creature that happens to be in the area. The navy denies this but they will not test it when humans are in the water. It is a physiological fact that low frequency waves in high amounts can cause damage and yet the navy refuses to admit any fault in the stranding of numerous animals every place that LFA is tested.Jan. 20 WTO revisitedLast day of data collection is today, and what a surprise when we get out on the cliffs we have not one but two broken theodolyte. The one my team was using the lock refused to let go and on the other one the lock refused to even lock. The wind was minimal and yet the seas were still pretty rou...
