Figure 7:

(A) North–south (positive–negative) ocean currents (m s−1) observed ∼ 200 m in front of the DIS acquired underway during a transect along the ice shelf front. Station locations and depth of TMC CTDs are indicated by the gray vertical lines. White areas indicate no SADCP data. Velocities were smoothed by a running mean, effectively removing velocities less than ±0.05 cm s−1. (B) Temperature anomalies (temperature at a given depth minus a depth-mean temperature) from XBT data acquired during the same transect. In both plots, the white contour is a multibeam estimate of the ice shelf draft, and the black contour is the −1.0 °C isotherm. Bathymetry is from Nitsche et al. (2007).

Ocean currents and temperature anomalies in front of the Dotson Ice Shelf.
