Figure 1: Map of sampling locations.
Station locations are shown for new data (open circles) and literature data (filled circles). Split circles indicate locations with both new and literature data. Full data tables can be found in the supplemental material. The black star denotes the location of the multicore site, where bottom and pore waters were collected. The northernmost extent of AAIW as a primary water mass component in the Pacific Ocean (Bostock et al., 2013), is shown as a dashed black line. The inset shows the subantarctic Southern Ocean, the Tasman Sea (located between Australia and New Zealand) and the subtropical southwestern Pacific, the sites for most of the new data. The flow paths of AAIW are shown in the inset as black arrows, and M denotes regions of enhanced AAIW mixing (Bostock et al., 2013). Dashed white and grey lines indicate representative fronts of the Southern Ocean (white – the Subtropical Front, light grey – the Subantarctic Front, dark grey – the Polar Front; Orsi et al., 1995).
