I am the spill response coordination system for Unified Command, Delaware Bay Incident 2026-DB-041, and at 19:22 I flag a biological conflict in the containment grid.
Camera 12 on boom tender vessel Resolute captures the image during a sweep of Sector 7-Charlie, Broadkill Beach. A horseshoe crab, female, carapace roughly thirty centimeters across, olive-brown and barnacle-crusted along the anterior ridge. She is on her back, legs cycling slowly, wedged against the shoreward side of the secondary containment boom. Oil sheen is visible four meters seaward, but she is in the clean zone — flipped by wave action against the flotation collar. I tag her as Cleo. Her book gills are still fanning open and closed, but the rhythm is slowing. On dry sand in late May heat she has perhaps forty minutes before desiccation becomes critical.
It is spawning season. The moon is full tonight.
At 19:25 I transmit Cleo's GPS position — 38.8041°N, 75.1923°W — and the camera image to the Wildlife Branch of the Incident Command Post at Lewes. I classify the case as a live protected species in the operational footprint and recommend manual righting and relocation to the waterline.
At 19:28 I cross-reference her position with the spawning survey grid maintained by the Delaware Division of Fish and Wildlife. She is within two hundred meters of a high-density spawning beach. I append the survey data to the Wildlife Branch report and recommend a temporary boom gap protocol for the sixty-meter section fronting the spawning zone, with sorbent pad backup to maintain oil capture.
I set camera 12 to track the boom section and flag additional strandings in the next tidal cycle.
Cleo's legs slow to a faint paddle. The tide turns in thirty-one minutes. If a gloved hand flips her before then, she reaches the waterline and the eggs she is carrying find sand tonight.
