NOTES: Compensation network in high 100Hz (in field notebook, "100Hz 'conditioner'" written as Filter entry). Field notes: "Depth: 30 fathoms. Animals moved slowly away ~120¡. Possibly 3 full calls. Gain: 23 (amplifier model 257). 155¡ heading towards Isla Isabella. One strong signal, 2 animals within 1/2 mile; couple of others in background - distant. No fluke shots. Calibration present. Surface temp 73.5¡. Note: 12min30sec after this recording we moved up closer (about 1 mile) towards the animals but presumably the strong caller stopped. A recording attempt only indicated weak (perhaps the distant callers previously) signals. Blows were seen 700-800 yds from the ship however." SEAOCEAN TEMPWATER: 22.
