“…(3) the Hikurangi Channel, which funnels gravity flows down the axis of Hikurangi Trough (toward the north-northeast) before bending sharply to the east (Lewis and Pantin, 2002); (4) the Ruatoria debris avalanche, which remobilized accreted trench sediments and slope deposits along the northernmost Hikurangi margin (Collot et al, 2001); and (5) two prominent basement highs on the subducting plate, Chatham Rise and the Hikurangi Plateau (Wood and Davy, 1994;Davy et al, 2008). In addition, the array of sampling sites encompasses the region's most influential ocean current, the Pacific Deep Western Boundary Current (DWBC) (Shipboard Scientific Party, 1999a;McCave et al, 2004).…”

“…The complex surface and deep‐water oceanography of the SW Pacific Ocean is strongly influenced by the physiography of the region, characterized by the presence of the north–south New Zealand microcontinent and by several submarine plateaus and rises (McCave et al ., 2004, and references therein; Fig. 1B).…”

“…The subantarctic inflow is represented by cool (<15°C in summer), less saline, macronutrient‐rich, micronutrient‐poor Subantarctic Water (SAW), which flows northward along the eastern side of the South Island before reaching the southern slope of Chatham Rise (e.g. Carter et al ., 2004; McCave et al ., 2004). Both these systems are strongly influenced by the regional bathymetry and wind fields (Hayward et al ., 2008).…”

“…The Chatham Rise is the main point of entry for several water masses into the Pacific Ocean. Hydrographic profiles from the region show the main deep‐water masses around Chatham Rise include: Lower Circumpolar Deep Water (LCDW, salinity of 34.71–34.73 psu and dissolved oxygen concentration of ∼200 µmol kg −1 ; Russon et al ., 2009) overlain, respectively, by the Pacific Deep Water (PDW) and the AAIW (McCave et al ., 2004, 2008) (Fig. 1C).…”

Through a multidisciplinary approach based on novel micropaleontological and geochemical analyses, the main paleoceanographic and paleoclimate changes that have influenced the surface‐ and deep‐water circulation in the SW Pacific Ocean (Chatham Rise, eastern New Zealand) during the last million years are reconstructed. This region represents a key area for investigating the climate evolution during the Pleistocene because here the largely wind‐driven Antarctic Circumpolar Current interacts with the west Pacific Ocean circulation via the Deep Western Boundary Current, the major source of deep water for the whole Pacific Ocean. To understand coupling or decoupling events between sea surface and bottom waters, a continuous marine sedimentary succession since 1.1 Ma, recovered by the IMAGES (International Marine Past Global Change Study) cruise in the SW Pacific Ocean (Core MD97‐2114), has been investigated based on calcareous planktonic and benthic microfossil content and C and O isotope record performed on planktonic and benthic foraminiferal tests. Results show the occurrence of long‐ and short‐term patterns of climate and ocean circulation in the last million years as the result of the interplay of ice‐sheet dynamics, surface tropical versus polar water inflow, and trophic status of the surface water.
