The ice shelf under Antarctica is about to get an up close and personal look from a robot submarine. A yellow submarine.

Its part of a US research team’s increased efforts to monitor glacial thaw. Its important research that could have global ramifications. That didn’t stop someone from asking if the color of the research vessel had anything to do with a certain song…

According to Steve McPhail of the British National Oceanography Center in Southampton who engineered the Autosub, the submarine is yellow because it makes it easy to spot when it surfaces. It’s color, he says, has “absolutely nothing” to do with the Beatles song “Yellow Submarine.”
