Atlantic Ocean statistics for 2026 show an area of about 106.4 million km² (41.1 million sq mi) with marginal seas, an average depth of 3,646 m and a deepest point of 8,376 m in the Puerto Rico Trench. The Atlantic is the second-largest ocean, covers about 20% of Earth’s surface and keeps its internationally recognized name, although Donald Trump floated “American Ocean” at rallies in October 2026.
Atlantic Ocean 2026 – Introduction
Atlantic Ocean statistics start with scale. The basin covers about 106.4 million km² with its marginal seas, or about 20% of Earth’s surface. It runs between the Americas to the west and Europe and Africa to the east. The Mid-Atlantic Ridge, a submarine mountain range, splits the floor down the middle.
The ocean also made news again in October of 2026. Donald Trump floated renaming it the “American Ocean” at several rallies. This report covers those remarks, the Atlantic’s location, area, depth and ridge, and the 2026 hurricane season. Where sources give different figures, the text says why. Area and depth change with how a source treats marginal seas.

The table sets out the main numbers. The Atlantic spans 106.4 million km² with its marginal seas and ranks 2nd of the five oceans. That equals about 20% of Earth’s surface. Its commonly cited average depth is 3,646 m, and its deepest point is 8,376 m in the Milwaukee Deep. The ridge that divides the floor runs about 16,000 km.
Two entries come from 2026 news. The National Hurricane Center counted 10 named systems through October 22. The rename entry reads none reported because the coverage reviewed shows remarks at rallies, not a signed order. The Gulf of Mexico and Lake Ontario naming moves were formal orders. The Atlantic proposal has not reached that stage in the reports reviewed.

The Atlantic sits between the Americas and Europe and Africa. The Arctic Ocean bounds it on the north and the Southern Ocean on the south. It holds 23.5% of the world ocean by area, second to the Pacific at 46.6%. The Indian Ocean holds 19.5%, the Southern Ocean 6.1% and the Arctic Ocean 4.3%.
The Mid-Atlantic Ridge defines the seafloor. It runs from Iceland to about 58°S along the boundary of 4 tectonic plates: the Eurasian, North American, South American and African plates. New crust forms at the ridge, so the ocean keeps widening by several centimeters a year. The ridge gives the Atlantic its two-trough shape, with basins on either side.

The Pacific is the largest ocean at 165.25 million km², about 1.55 times the Atlantic. The Atlantic’s 106.46 million km² equals about 64% of the Pacific and about 1.5 times the Indian Ocean at 70.56 million km². The Southern Ocean covers 21.96 million km² and the Arctic 15.56 million km². Shares of the world ocean sum to 100%.
Depth tells a different story. The Pacific averages 4,280 m, the Indian Ocean 3,741 m and the Atlantic 3,646 m. The Southern Ocean averages 3,270 m. The Arctic is by far the shallowest at 1,205 m, about one third of the Atlantic’s average. Sources vary on exact figures, so treat each value as an approximate median.

Marginal seas add 24.0 million km² of area and 31.1 million km³ of volume. They also lower the average depth, because they are shallower than the open ocean. With them, the Atlantic averages 3,339 m. Without them, it averages 3,926 m. The commonly cited 3,646 m sits between the two, so check which basis a source uses.
The deepest point is the Milwaukee Deep in the Puerto Rico Trench at 8,376 m, or 27,480 ft. Victor Vescovo made the first crewed descent to the trench floor on December 21, 2018. The Mid-Atlantic Ridge crest sits far higher, at an average water depth of about 2,500 m, which shows how much relief the ocean floor holds.

Source: TIME, RTE, Euronews and Al Jazeera coverage, October 2026; White House orders as described in news reports.
Trump first floated renaming an ocean on October 10, 2026, at a rally in Clarksville, Tennessee. He suggested either the Atlantic or the Pacific could carry a new name. By October 22, reports said he told a South Carolina rally that Google’s chief executive declined to relabel the Atlantic as the “American Ocean.” Trump said the executive told him oceans are different because they touch many countries. He later said he would pass but would call it the American Ocean anyway.
The earlier cases were formal orders. The Gulf of Mexico order came in January 2025, about 21 months ago. The Lake Ontario order came in August 2026. Canada’s prime minister rejected the lake name. Coverage describes the Atlantic comments as rally remarks, and none of the reports reviewed describes a signed order. Maps and scientific sources still use the name Atlantic Ocean.

The season has run below average. It produced 10 named systems through October 22, against a 1991-2020 average of 14.4. NOAA’s May outlook called for 8 to 14 named storms. Its August update lowered that to 7 to 13, as El Niño raised wind shear. Hurricane Isaias, the first hurricane, formed on October 8, tying 1905 for the latest first hurricane.
Isaias peaked at 120 mph and landfall came near Destin, Florida, on October 10 UTC. The season’s damage tops $3.84 billion and its fatalities reach 13. Arthur caused about $1.3 billion in losses and 4 deaths. Isaias caused over $2 billion and 9 US deaths. The ACE index of 19.5 is far below the median range of 71 to 123 for a typical season.

Nine of the 10 systems stayed at tropical or subtropical storm strength. Fay peaked at 70 mph and lasted 11 days, from September 19 to September 29, the longest run of the season. It nearly became the first hurricane before wind shear weakened it. Bertha and Edouard each peaked at 60 mph. Dolly was the weakest at 40 mph.
Isaias drove most of the toll. It peaked at 120 mph, and it caused more than $2 billion in damage and 9 US deaths. Arthur caused about $1.3 billion in losses and 4 deaths, with rainfall near 30 inches in parts of Louisiana. Bertha cost $400 million and Edouard $140 million. Together, these four storms account for the season’s more than $3.84 billion in damage and 13 deaths.

Forecasters expected a near-normal to below-normal season, and the El Niño that formed in mid-2026 pushed them lower. The University of Arizona’s April call of 20 named storms was the highest. Colorado State cut its forecast from 13 in April to 9 by early July. NOAA trimmed its range from 8 to 14 in May to 7 to 13 in August. The actual count of 10 named systems landed inside NOAA’s range and one above the Colorado State low.
Hurricanes fell short of every forecast. Actual hurricanes stand at 1, against forecasts from 2 to 9. Major hurricanes stand at 1, inside NOAA’s August range of 0 to 2. The 1991-2020 average of 7.2 hurricanes shows the gap. Wind shear stayed high, with Caribbean shear in July the highest since records began in 1979.
