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).
