The Atlantic Ocean is the second largest ocean, situated between the Americas, Europe and Africa. Three of Atlantis's eight city-states are located in the Atlantic; Shayeris in the north, Poseidonis in the middle, and Xebel in the south.[1]
In the Manta-Sub, Vandal Savage and Black Manta visited the still-catatonic Kaldur'ahm. Savage brought Psimon with him to attempt to restore his mind.[6]

Fearing her secret might be exposed, Tigress sedated Psimon with a poison dart. Now, she and Deathstroke had to abduct Miss Martian, so she could restore Kaldur's memory. They left in the Manta-Flyer.[7]
Atlantic Ocean April 9, post-05:20EDT
After successfully abducting Miss Martian in Chicago, Tigress and Deathstroke took her back to the submarine. There, she could begin healing Kaldur. Deathstroke used the Manta-Flyer to trail the sub, outside the reach of Miss Martian's powers.[7]
Fixing Aqualad's mind went quicker than expected, and the three heroes had to worry about getting Miss Martian to safety. The opportunity rose when Sportsmaster and Cheshire infiltrated the sub. After a fight aboard the submarine, the two assassins and Miss Martian escaped.[8]
Miss Martian picked up Lagoon Boy from Poseidonis. They travelled through the Atlantic in the Bio-Ship, heading west to Blüdhaven. At the same time, several other members of the Team crossed the Atlantic eastward, to Bialya.[9]
Aqualad and Lagoon Boy worked together to destroy one of the Reach's Magnetic Field Disruptors. Aqualad took care of the drones, allowing La'gaan to sabotage the disruptor.[10]
