Anti-cyclonic eddy imprint on calcite geochemistry of several planktonic foraminiferal species in the Mozambique Channel
Highlights: • We coupled LA-ICP-MS Me/Ca single-chamber composition of four planktonic foraminifera with eddy induced hydrographic changes • The Mg/Ca-based temperature difference between N. dutertrei and G. scitula are likely to be an eddy proxy suitable for down-core application • Near-surface dwe...
