Fig. 9: Simulated overturning circulation in the Totten Ice Shelf cavity.
From: On-shelf circulation of warm water toward the Totten Ice Shelf in East Antarctica
Ocean temperature (°C, color) and overturning circulation (mSv, 1 mSv = 1.0 × 103 m3 s−1, black solid and dotted contours) in the Totten Ice Shelf (TIS) cavity from the CTRL case in (a) distance-depth and (b) distance-density domain and (c) from the NOTR case in distance-density domain. The horizontal axis is the distance from the ice-shelf front, and positive (negative) values point to the inside (outside) of the cavity (see also Fig. 7d for the area classification). Green lines in (a) show the contours of the potential density anomaly. Negative values (dotted lines) of the streamfunctions indicate clockwise circulation. The bottom colorbar in (a) corresponds to the areas classified in Fig. 7d. The model results are the annual-mean climatology averaged for 1991‒2020, calculated from the monthly values of water properties and velocity.
