Figure 2. Map of the SERPENT survey transect. A total of 50 EM receivers were deployed across the Middle America Trench offshore Nicaragua, where the 24 Ma Cocos plate subducts beneath the Caribbean plate. Receiver locations spanned the abyssal plain, the visibly faulted outer rise, and the continental slope and shelf at 10 and 4 km spacing. A cluster of active forearc seeps are located adjacent to the survey transect (blue circles).
