What is the difference between Oceanview and Mediterraneo? 
What about Bahia? 

Mediterraneo, introduced 2003, is an updated version of Oceanview, which had appeared in 1998.  Dinner plates from both reveal no detectable modifications to the pattern, aside from a slight colour difference.  The major distinction between the two patterns is the decoration of the side plates and luncheon plates.

Oceanview side plates & luncheon plates have all-over patterns that resemble aquatic plants.  Similar designs are also found on Oceanview's stoneware Coordinates, like teapots and cream & sugar sets.

Oceanview cups are tall and narrow, in the Occasions style, and depending on their age, they are made of either Suprema glass-ceramic or Corning Ware.  Soup/cereal bowls are 6¼" with a coupe shape and a pattern around the side.

Mediterraneo side plates are patterned only on the rim, matching the dinner plates exactly.  It is unclear whether Mediterraneo luncheon plates exist, but if they do, they probably replicate the dinner plate's decoration too.

Mediterraneo cups are stoneware, short and small, and hold 6-7 oz.  Soup/cereal bowls are 7¼" with a rimmed shape and a blue band.

Also launched in 2003, Bahia is similar to Oceanview & Mediterraneo, being a scaled-down version of the same motif, but it uses a different plate style.  Plates & bowls in Bahia are coupe rather than rimmed, and mugs are the large solid-coloured stoneware type.
