NOTES: MLNS notes: interesting to look at effects of increasing noise on fish vocalization rates. Gain is turned down roughly halfway into the cut as the tanker noises get loud.
Tape notes: "croaker chorus, tapper, thumper, HJH, and low boom tonal type... pieces of screw noise from freighters (7-8 miles)." ... (later) a ship about 2 miles North... TEMPWATER: 22
