🐢 Sea Turtle Navigation: The Magnetic Map, Inclination and Ocean Gyre Migration

Loggerhead hatchlings steer by the Earth's magnetic inclination and intensity as they ride a Stommel-type North Atlantic gyre: a dipole-field signpost map, gradient-descent navigation versus passive drifters, magnetic-displacement tank tests, geomagnetic secular drift and light disorientation on a dusk beach. Unlike the existing turtle sims (hatchling, leatherback, generic ocean), the focus here is the geomagnetic map itself and its measured checks.
