Map of sample locations. (A) Cruise track (blue line) and 302 discrete sampling stations included in the cruise data. Cruise station numbers (BS_###) progress from 001–303 (only transect stations are labelled in the figure for readability). CTD stations are indicated by white crosses. Longitudinal stations are indicated by light blue circles. Stations belonging to cross-slope transects are indicated by red circles with the range in station numbers in red text. (B) Land-based sampling, with sample numbers BL_### ranging from 001–170. Beach transect sites (including nearshore surface water and groundwater samples) are shown by dark red X’s, with corresponding sample numbers labeled in dark red text. Blue triangles denote river sampling stations Fig. 2B).
