Meridian Ocean is one of three oceans released on January 31, 2012. The ocean is a doubloon ocean created through the merger of the Viridian and Malachite Oceans, and open testing lasted from January 9 to January 16, 2012.
The mergers of the English-language oceans were hinted at on December 7, 2011, when the "Intrepid Explorer" Velasco Thorsson posted his journals on the Hear Ye! Announcements forum. The mergers were subsequently announced the next day by Hermes. On the same day, voting on the new oceans' names opened to the general public, who voted on the name "Cerulean" for the new subscription ocean, "Emerald" for the Sage/Hunter merger, and "Meridian" for the Viridian/Malachite merger.
Meridian has one hundred and nine islands divided among eleven archipelagos. There are forty-five colonized islands. The area that comprises the former Viridian Ocean has the same geography as the former Cobalt Ocean and the late Crimson Ocean.
