Fig. 7From: The pteropod species Heliconoides inflatus as an archive of late Pleistocene to Holocene environmental conditions on the Northwest Shelf of AustraliaSeasonal and annual profiles of the theoretical aragonite δ18O equilibrium values for Site U1463. A direct comparison with the values measured for H. inflatus (gray bands) indicates calcification depths between 80 and 155 m, with annual averages of 95–140 mBack to article page
