We reinvestigated tephra and cryptotephra stratigraphy of the Late Pleistocene deep-sea C9001C cores collected during the D/V Chikyu shakedown cruise. We identified 26 glass shard concentration horizons (spikes) corresponding to four previously reported tephras (G1, G2, G3, and G4 from top to bottom...
