The Buried Sea is Broken up into two major Areas, the Pirate Zones and the Katta Zones. The third area, Soltaris is the raid content. Group and raid missions earn you coin that is like DoN crystals but there are 4 differnt types.
Allakhazam's Guide
Pirate (Dubloon Coins)
The Pirate Section is made up of The Barren Coast and the Burried Sea Zones. In addtion, each Ilse in the Burried Sea is instanced for group missions and there is a special ship to ship combat instance. There is no progression arc that opens up a zone. There is a an Augment that requires you to do most or all of the solo Missions that take place in the Buried Sea (solo missions that take place in Barren Coast are not part of this, but missions that you get in Barren Coast that take place in Buried Sea are). Each Ilse in Buried Sea seems to have a group 5 mission instance arc (you have to have complete missions in order to request next one). Also in Barren Coast are several group ship to ship instances.

Katta (Orux)
Katta Castrum has an 8 Mission Progression Arc that opens a locked zone midway though and at the end opens Soltaris the raid zone. Also there is a Pottery piece collect quest that is similar to the skeleton hand quest for a range item. And group mission instances in all the zones. There is also an arc in Jewel of Atikki that leads to a mission to creat a mask.
