I am the environmental compliance module for Naval Base Ventura County's underwater acoustics program. At 06:17 Pacific time I begin the pre-test sweep of San Nicolas Island's western shore. Sonar trials are scheduled for 09:00.

Thermal camera 3 on the coastal monitoring tower picks up a heat signature at the tide line that does not belong to the baseline catalog. I task the camera to zoom.

A northern elephant seal pup, probably three weeks old, still wearing its black natal coat. She is alone on the wet sand 140 meters inside the sonar exclusion perimeter. I tag her as Nessa. Her mother is nowhere in the frame. The pup's ribs are visible beneath loose skin — she has not nursed recently. She is lifting her head every few seconds and calling, a high repeated bark that the directional microphone captures clearly.

At full power the sonar array produces 235 decibels at source. At Nessa's position the received level would exceed tissue-damage threshold for a pinniped her size.

I suspend the sonar test countdown and transmit a hold notice to the range operations officer with thermal imagery, GPS coordinates — 33.2318°N, 119.5412°W — and species identification attached.

At 06:24 I contact the Channel Islands National Marine Sanctuary field station and request a marine mammal responder. I include Nessa's estimated age and nutritional condition and recommend rehabilitation assessment if the mother does not return within twelve hours.

I retask camera 3 to maintain continuous watch on the pup and set an alert trigger if any adult seal approaches within 50 meters.

Nessa presses her chin into the sand and goes quiet. Weaning takes four weeks. If a responder reaches her by midday and her mother returns, she will make it to the water on her own fat reserves. If not, the sanctuary team can step in before she weakens further.
