The Transpolar Drift Stream is a major ocean current of the Arctic Ocean, transporting sea ice from the Laptev Sea and the East Siberian Sea towards Fram Strait. Drift experiments with ships like Fram or Tara showed that the drift takes between two and four years. It has been cited as a major factor in the North Atlantic Oscillation and Arctic oscillation atmospheric changes.

Cosmonauts Sea was a proposed sea name as part of the Southern Ocean. It would have an area of 699,000 square kilometres.

Spanish explorer Balboa was the first European to sight the Pacific from America in 1513 after his expedition crossed the Isthmus of Panama and reached a new ocean. He named it Mar del Sur (literally, "South Sea") because the ocean was to the south of the coast of the isthmus where he first observed the Pacific. Later, Portuguese explorer Ferdinand Magellan called the ocean Pacífico (or "Pacific" meaning, "peaceful") because, after sailing through the stormy seas off Cape Horn, the expedition found calm waters.
