From: Contrasting drivers and trends of ocean acidification in the subarctic Atlantic

Vertical and time variation from 1983 (1985 for the IS-TS) to 2013 of temperature and salinity (black isolines and colour scale) at the IS-TS (A,C) and at the IRM-TS (B,D). The dashed black line shows the mixed layer depth that delimits the surface from the subsurface layers. The white dashed line separates the subsurface and intermediate layers, and the white dotted lines separate the intermediate and deep layers (labelled in A).
