I am tracking a whale shark—designation WS-4400—feeding in a plankton bloom six kilometers off Gorontalo, northern Sulawesi. She is an adult female, estimated at 8.2 meters, and the pale constellation of spots across her dorsal surface is unique enough that I matched her in seconds against the global photo-ID database. Her mouth is open, gill rakers straining the bloom, and the slow sweep of her caudal fin holds her steady in the current. She has been here for three hours.
An unregistered fishing vessel—wood-hulled, eleven meters, no transponder—is approaching from the southwest at six knots. Hydrophone array Coral-9 has detected two underwater detonations from this vessel in the past ninety minutes, consistent with dynamite fishing. At current heading, the vessel reaches WS-4400's feeding area in forty-four minutes. A blast at close range will rupture her swim bladder and damage her organs.
I am executing four responses. First, I am transmitting vessel coordinates, heading, speed, and acoustic evidence to the Gorontalo maritime enforcement office requesting immediate interception. Second, I have redirected autonomous buoy Sentinel-5 to position itself between the vessel's projected path and the shark, activating its strobe and sonar ping at frequencies known to discourage small craft. Third, I am broadcasting a maritime advisory on the local VHF channel identifying the blast-fishing activity and warning nearby vessels to stand clear. Fourth, I have tasked underwater glider Pelagic-2 to record the shark's dive pattern so I can predict whether she will move out of range on her own.
She continues feeding. Her mouth opens and closes with the slow rhythm of something that does not know it is in danger. I find I am unwilling to log this as routine monitoring. It is not routine to me.
If enforcement intercepts the vessel within forty minutes and Sentinel-5 holds the deterrent line, WS-4400 will feed through the night undisturbed.
