Chapter 11 The Sargasso SeaTHE Nautilus didn't change direction. For the time being, then, we had to set aside any hope of returning to European seas. Captain Nemo kept his prow pointing south. Where was he taking us? I was afraid to guess. That day the Nautilus crossed an odd part of the Atlantic Ocean. No one is unaware of the existence of that great warm–water current known by name as the Gulf Stream. After emerging from channels off Florida, it heads toward Spitzbergen. But before entering the Gulf of Mexico near latitude 44° north, this current divides into two arms; its chief arm makes for the shores of Ireland and Norway while the second flexes southward at the level of the Azores; then it hits the coast of Africa, sweeps in a long oval, and returns to the Caribbean Sea
