Fig. 5: The spatial distribution of the in-situ data used.

Map showing the distribution of the in situ surface HPLC (n = 4173; blue circles) and MAP-IO flow cytometry (n = 941; purple circles) observations used. The HPLC data points plotted on the map comprise the publicly available dataset from Soppa et al.42. The MAP-IO flow cytometry dataset is also publicly available on SEANOE from Thyssen et al.45.
