BACKGROUND

Geological Setting

A description of the geological setting of the Costa Rica margin sites can be found in the "Leg 205 Summary" chapter (Shipboard Scientific Party, 2003) of the Leg 205 Initial Reports volume (Morris, Villinger, Klaus, et al., 2003).

Because the Costa Rica hydrogeology ancillary program will reoccupy previously drilled sites, no additional site survey data are required.
