Alligator Maps

This image illustrates the complex physical oceanography in the region of the Alligator's loss. The USS Sumpter and Alligator's last known fix at noon on April 3 is approximately 50.5 nautical miles south-southeast of Cape Hatteras and is approximately 36 nautical miles south-southeast of the Monitor National Marine Sanctuary. This false-color image depicts average sea surface temperatures based on climatology for early April. The Gulf Stream travels up the coast of the United States and separates the warmer waters of the Sargasso Sea in the south from the colder waters of the continental shelf and slope. The warmer waters are shown in orange and red, while the cooler waters are shown in green, blue and purple. At speeds of up to 5.6 mph, the Gulf Stream is the fastest ocean current in the world.
