Fig. 2: Conservative Temperature-Absolute Salinity-Time diagrams.
From: Ocean variability beneath Thwaites Eastern Ice Shelf driven by the Pine Island Bay Gyre strength
a Location of Conductivity-Temperature-Depth (CTD) stations (yellow dots) in Pine Island Bay (PIB) collected in January and February 2020, and the AMIGOS3a (blue dot) and AMIGOS3c (red dot) sites. Thwaites Eastern Ice Shelf (TEIS) and Pine Island Ice Shelf (PIIS) are depicted. Ice thickness and bathymetry from BedMachine Antarctic v2, ref. 37. Note that BedMachine is not updated to the most recent calving front. b Conservative Temperature-Absolute Salinity diagram for the CTDs (grey dots) and AMIGOS colour-coded by the month that the measurement took place. Red lines are neutral density isopycnals. Magenta dashed is the Gade line23 and black dashed is the mixing line between modified Circumpolar Deep Water (mCDW) and Winter Water (WW). Zoom-in for c, AMIGOS3c-Upper, d AMIGOS3c-Lower, e AMIGOS3a-Upper, and f AMIGOS3a-Lower.
