Heinrich event imprints in the Okinawa Trough: evidence from oxygen isotope and planktonic foraminifera
Planktonic foraminiferal faunas, oxygen isotope and modern analog technique sea surface temperature records were obtained in piston core DGKS9603 (28degrees08.869'N, 127degrees16.238'E, water depth 1100 in) collected from the middle Okinawa Trough. During the last glaciation, four cold eve...
