Figure 4

Relationship between observed pCFC-12 and pSF6 in AABW. Green and dark gray asterisks indicate new AABWs along Wild Canyon (neutral density: γn > 28.27 kg m−3, θ <  − 0.4 °C)10 and the other AABWs (γn > 28.27 kg m−3), respectively. Black line and black numbers indicate the year-to-year variations in atmospheric partial pressure and the year, respectively. Blue and gray lines indicate the year-to-year variations in LCDW and DSW, respectively. Blue and gray crosses show the averages and standard deviations of the estimated LCDW and DSW in 2020, respectively. Red dashed lines and red numbers indicate the estimated year-to-year linear relationship of AABW and the year, respectively.
