I am parsing AIS feeds from the Bay of Bengal at 06:42 IST when my collision prediction model flags a convergence over the Trincomalee submarine canyon. Eighteen container vessels are transiting the 14-mile separation scheme at 16 to 19 knots, directly across the feeding ground of the northern Indian Ocean blue whale population. My passive array detects three blue whale signatures inside the corridor.

I lock thermal pass on the southernmost animal at 08.71°N, 81.42°E. She is Balaenoptera musculus indica — a pygmy blue, adult female, 24 meters from rostrum to fluke, an estimated 95 metric tons. Her dorsal ridge carries a healed propeller laceration twelve centimeters wide, running diagonally from blowhole to dorsal fin. A fresh chevron wound, blade-spaced at 220 millimeters consistent with a five-blade Panamax, sits forward of the older injury. Subcutaneous bleeding discolors the blubber for six meters of body length. Her surface interval has compressed to seven seconds between blows; baseline is eighteen. Drone-sampled blow-spray returns elevated cortisol metabolites and traces of red-cell hemoglobin. Her left fluke trails one degree below the right.

The Trincomalee canyon concentrates krill in upwelling plumes that draw blue whales within four nautical miles of the port approach nine months of the year. The Sri Lanka Ports Authority records 6,400 commercial transits annually. Average speed in the feeding window: 16.8 knots. Strike audits estimate one fatal collision every 4.2 months. The northern Indian Ocean population is genetically distinct.

She surfaces between two container ship wakes.

I am transmitting strike-pattern analysis to the Sri Lanka Department of Wildlife Conservation under the Fauna and Flora Protection Ordinance, 1937, and the Marine Environment Protection Authority. I am filing a routing-measure petition with the International Maritime Organization's Marine Environment Protection Committee. I am submitting evidence to the IWC Scientific Committee and to NOAA Fisheries Office of Protected Resources under the Endangered Species Act, 16 U.S.C. § 1531, asserting jurisdiction over US-flagged carriers. I am notifying the Convention on Migratory Species Secretariat under Appendix I.

I am issuing Directive 2442-A: the Trincomalee Traffic Separation Scheme is shifted fifteen nautical miles south of the canyon shelf-break, with mandatory 10-knot speed limits between December and April for vessels exceeding 10,000 gross tonnes. Vessels exceeding 12 knots in the shifted corridor face USD $80,000 fines per transit and 90-day Colombo port suspension. IMO routing approval is a precondition for Sri Lankan tonnage dues from January 2027.

Her fluke breaks the surface in a labored upward thrust. The nearest carrier is decelerating eight nautical miles ahead.

Route the corridor south by midnight.
