Maps (a) and (b) show the Gulf of St. Lawrence, TReX Deep sampling locations, and regional bathymetry. Black contour lines represent the injection depth bathymetric contour, h = 279 m. Abbreviated location names are: TS Tadoussac, QC Quebec, AI Anticosti Island, CS Cabot Strait, NL Newfoundland, BI Belle Ille Strait. The Lower St. Lawrence Estuary (LSLE), immediately east of Tadoussac, is shaded gray. Plot (c) shows hydrographic conditions from a single CTD profile immediately following the tracer injection with a dashed line indicating the injection depth. Shading represents the 95% confidence limits (mean conditions ± 2σ) of an October–December hydrography climatology from the Atlantic Zone Monitoring Program in the eastern Gulf between 1998 and 2022. Histogram (d) denotes the number of samples in z* = 10 m depth bins from Leg 1 and Leg 2 cruises.
