摘要: [1] Planktic foraminiferal assemblages from Ocean Drilling Program (ODP) site 1119 and Deep Sea Project (DSDP) 594 are used to estimate sea surface temperatures (SSTs) over the past ∼900 kyr (marine isotope stages (MISs) 23–1) in southwest Pacific Ocean, east of New Zealand. Comparison these long SST records allows us document cyclic migrational history water masses fronts, especially N-S oriented segment Subtropical Front (STF), known as Southland Front. During most interglacials, summer SSTs were 10–12°C both sites, indicating that overlain by Subantarctic Water (SAW) was located landward them. peaks MISs 11 5.5, estimates considerably warmer than modern, suggesting southern edge E-W trending STF expanded southward Bounty Trough, Current contained a greater proportion (STW) it does today. glacials, inshore ODP (7–10°C) ∼4°C DSDP 594. This implies migrated offshore with lowered levels lie between two sites.
