Extended Data Fig. 7: Recent and projected bottom water property changes due to the meltwater anomalies.
From: Abyssal ocean overturning slowdown and warming driven by Antarctic meltwater
a–c) Surface water-mass transformation (on the continental shelf; 10−5 m s−1) and bottom seawater age anomaly (in the abyss; years), d–f) bottom salinity anomaly (psu) and g–i) bottom temperature anomaly (°C) from the meltwater component during the decades 2001–2010, 2021–2030 and 2041–2050, respectively, relative to the control run. Grey contours represent the 4000 m isobath, and the black line denotes the 1000 m isobath around the Antarctic margin. The surface water-mass transformation rate is computed across the 32.57 kg m−3 isopycnal (referenced to 1000 m), across which the SWMT shows the most significant reduction.
