The Drake Passage is the body of water between the southern tip of South America (called Cape Horn) and the northern tip of Antarctica (essentially, at our northern-most sampling sites). To remind you of the geography here: The southern tip of South America is a large island called Tierra del Fuego. The Strait of Magellan passes between mainland South America and Tierra del Fuego, and the very southern tip of Tierra del Fuego is called Cape Horn. So, Cape Horn is the southern-most point of South America, and the Drake Passage flows below it (between Cape Horn and the Antarctic Peninsula), connecting the Pacific and Atlantic oceans.
The Drake Passage is named after Sir Francis Drake, a sea captain during the Elizabethan Era in the 1500s who circumnavigated the world in one journey. There are rumors that Drake discovered this passage during his journey by accident. The story is that his ships were trying to get through the Strait of Magellan (because that was the known passage between the Atlantic and Pacific), but they were blow too far south by a bad storm and discovered that the continent ended and the oceans were connected by this Passage. It’s possible that it happened this way, but some argue that it’s not likely (and there are no accurate historical accounts to prove it happened). So, naming the passage after Sir Francis Drake might be a misnomer!
The Drake Passage is famous for having very rough seas. This is because of a mixture of ocean currents and wind. The Antarctic Circumpolar Current, or ACC, is an ocean current that flows clockwise around Antarctica. Because Antarctica is a nice, round continent and there are no major chunks of land in the ocean surrounding it (just little islands), there is a clear path for the current to move in a circle around Antarctica. That makes it a very strong current, in fact the strongest one on the planet!

In the Drake Passage, the cold-water ACC meets with the warmer currents from the Atlantic and Pacific oceans. These different currents don’t mix together neatly, and the water gets famously rough here in the Drake where they come together. There are also some very strong westerly winds (that is, winds coming from the west) that make it very windy, in addition to the choppy mixing of ocean currents.
Some days are choppier and windier than other, of course. When we crossed the Drake at the beginning of our trip, the conditions were on the bad side. We had fairly large waves and very high winds (around 40 to 50 knots, sometimes even up to 60 knots). Worse conditions have certainly been reported for the Drake, but we had 2-3 days of constant wind and waves. It made for a very tough few days! This time, the weather was better. Winds were only around 30-40 knots, and while we had some big waves, it was just occasional. We didn’t have two solid days of rough seas. We fared much better this time! Last time, all of us spent most of the time laying in our bunks. This time, we were all up and moving around more, eating most of our meals like normal.
It’s hard to get a good picture to show you the waves, because you have to catch it at just the right moment. Plus, it’s hard to stand outside on deck in heavy seas! This is the best I could do. (And remember, this is from today, the much nicer trip across the Drake compared to when we were last here.)

The Drake Passage is the body of water betwe South America's Cape Horn, Chile, Argtina and the South Shetland Islands of Antarctica. It connects the southwestern part of the Atlantic Ocean (Scotia Sea) with the southeastern part of the Pacific Ocean and extds into the Southern Ocean. The passage is named after the 16th-ctury glish explorer and privateer Sir Francis Drake.
The Drake Passage is considered one of the most treacherous voyages for ships to make. Currts at its latitude meet no resistance from any landmass, and waves top 40 feet (12 m), giving it a reputation for being the most powerful convergce of seas.

As the Drake Passage is the narrowest passage (choke point) around Antarctica, its existce and shape strongly influce the circulation of water around Antarctica and the global oceanic circulation, as well as the global climate. The bathymetry of the Drake Passage plays an important role in the global mixing of oceanic water.
In 1525, Spanish navigator Francisco de Hoces discovered the Drake Passage while sailing south from the trance of the Strait of Magellan.
Because of this, the Drake Passage is referred to as the Mar de Hoces (Sea of Hoces) in Spanish maps and sources, while almost always in the rest of the Spanish-speaking countries it is mostly known as “Pasaje de Drake” (Argtina, mainly), “Paso Drake” or “Mar de Drake” (Chile, mainly).

The passage received its glish name from Sir Francis Drake during his raiding expedition. After passing in 1578 through the Strait of Magellan with Marigold, Elizabeth, and his flagship Gold Hind, Drake tered the Pacific Ocean and was blown far south in a tempest. Marigold was lost and Elizabeth abandoned the fleet. Only Drake's Gold Hind tered the passage.
On December 25, 2019, a crew of six explorers successfully rowed across the passage, becoming the first in history to do so.
The Drake Passage oped wh Antarctica separated from South America due to plate tectonics, however, there is much debate about wh this occurred, with estimates ranging from 49 to 17 million years ago (Ma).

The oping had a major effect on the global oceans due to deep currts like the Antarctic Circumpolar Currt (ACC). This oping could have be a primary cause of changes in global circulation and climate, as well as the rapid expansion of Antarctic ice sheets, because, as Antarctica was circled by ocean currts, it was cut off from receiving heat from warmer regions.
The 800-kilometre-wide (500 mi) passage betwe Cape Horn and Livingston Island is the shortest crossing from Antarctica to another landmass. The boundary betwe the Atlantic and Pacific Oceans is sometimes tak to be a line drawn from Cape Horn to Snow Island (130 kilometres (81 mi) north of mainland Antarctica), though the International Hydrographic Organization defines it as the meridian that passes through Cape Horn: 67° 16′ W.
The other two passages around the southern extremity of South America — the Strait of Magellan and the Beagle Channel — have frequt narrows, leaving little maneuvering room for a ship, as well as unpredictable winds and tidal currts. Most sailing ships thus prefer the Drake Passage, which is op water for hundreds of miles.
How To Survive The Drake Passage Without Getting Seasick
No significant land sits at the latitudes of the Drake Passage. This is important to the unimpeded eastward flow of the Antarctic Circumpolar Currt, which carries a huge volume of water through the passage and around Antarctica.
The presce of the Drake Passageway allows the three main ocean basins (Atlantic, Pacific and Indian) to be connected via the Antarctic Circumpolar currt (ACC), the strongest oceanic currt, with an estimated transport of 100–150 Sv (Sverdrups, million m
/s). This flow is the only large-scale exchange occurring betwe the global oceans, and the Drake passage is the narrowest passage on its flow around Antarctica. As such, a significant amount of research has be done in understanding how the shape of the Drake passage (bathymetry and width) affects the global climate.

Oceanic and climate interactions [ edit ] Major features of the modern ocean’s temperature and salinity fields, including the overall thermal asymmetry betwe the hemispheres, the relative saltiness of deep water formed in the northern hemisphere, and the existce of a transequatorial conveyor circulation, develop after Drake Passage is oped.[12]
The plot shows an yearly average (2020) of the surface currt strgth (from GODAS dataset), together with streamlines. Following the streamlines, it is easy to see that the currt is not closed in itself but interacts with the other ocean basins (connecting them). The Drake Passage plays a major role in this mechanism.
The importance of an op Drake Passage extds farther than the Southern Ocean latitudes. The Roaring Forties and the Furious Fifties blow around Antarctica and drive the Antarctic Circumpolar Currt (ACC). As a result of Ekman Transport, water gets transported northward from the ACC (on the left-hand side while facing the stream direction). Using a Lagrangian approach, water parcels passing through the Drake Passage can be followed in their journey in the oceans. Around 23 Sv of water is transported from the Drake Passage to the equator, mainly in the Atlantic and Pacific Oceans.
