Figure 3 . Distribution of hydrographic data and isopycnal
watermass properties of ASW and CDW. Data density per 75 km data radius
(top), Conservative Temperature (middle), and isopycnal pressure
(bottom) are presented for ASW (left) and CDW (right). Areas with less
than 10 data points within the 75 km radius are masked in gray. White
contours in middle/bottom panels denote isopycnal spiciness/thickness
(by 0.05 kg m-3/100 m intervals), respectively, and
thick white contour is –0.15 kg m-3/300 m for each
panel. SB (red) and isobaths with 1,000 m intervals (black) are also
shown.
