Abstract:
Planktic foraminiferal assemblages in a composite section from two cores (MD06-2989/2986) off the west coast of New Zealand's South Island (42-43.5 degrees S) provide a 1 myr (MIS 31-1) sea-surface temperature (SST) record ( approximately 3-4 kyr resolution) in the Tasman Sea. A significant overall faunal change occurred near the end of the mid-Pleistocene Climate Transition (MPT) at approximately 600 ka (MIS 15). Mean annual SSTs were estimated using the Artificial Neural Network (ANN) method. Glacial-interglacial (G-I) cycles in the MPT had approximately 9 degrees C SST range, whereas in the post-MPT SST range was approximately 6-7 degrees C. The SST and faunal changes imply that the Subtropical Front (STF) migrated approximately 6 degrees in latitude to lie just north of the sites in MPT glacials (MIS 28-16), but only migrated 3-5 degrees north in post-MPT glacials. These G-I latitudinal migrations of the STF west of New Zealand contrast with the situation east of New Zealand, where migrations of both the STF and Subantarctic Front were prevented by the Chatham Rise and Campbell Plateau. Subtropical Water is inferred to have only flowed around the south of New Zealand (as it does today) during MIS 11 and the Late Pleistocene-Holocene (MIS 5-1).
