Figure 1. Map of study region along the western Antarctic Peninsula. The small dots are regular
hydrographic stations, colored to indicate the percent meteoric water (predominantly
glacial melt) in the water column in January 2011 (Meredith et al., 2013). Red letters show
locations of Palmer (P) and Rothera (R) stations. KG = King George Island. C = Charcot Island.
Hydrographic lines (colored dots) are 100 km apart (north to south) and 20 km apart (cross
shelf). The continental shelf break is to the left.
