Summary A cluster of approximately 100 relative large craters (from 100 m to 500 m in diameter) exists at seabed over a 65 km 2 area offshore Nigeria. Cone structures interpreted as diatrems and underlying vertical pipes are observed on seismic data below the craters. The pipes can be traced continuously from seabed and 1000 to 1300 m down
