Figure 6. Leftmost scatterplot (a) illustrates the
relationships between βFC and βSal for
each station colored by the station’s associated SGA letter. The top
right scatterplots (b) illustrate βFC and
βSal for each station within the SGA. The lower right
histograms (c) show the distributions of βSal values
broken down by SGA letter. Both (b) and (c) further demonstrate the
spatial variation in salinity trends and relationships between
βFC and βSal across the coast.
There were weakly correlated, somewhat grouped relationships between
βFC and βSal along the full coast
(Figure 6a), with strongly negative correlations in SGA B and somewhat
in C, weakly correlated relationships in SGAs D, F, G, and H, and a
positive correlation in SGA E (Figure 6b). When broken out by SGA
(Figure 6c), the βSal distribution varied from lower
negative values with higher spread in the southern SGAs A, B, and C, to
higher positive βSal values with more narrow spread in
the central SGAs D, E, and F. SGAs G and H had lower
βSal values than the more central areas, but higher than
the more southern areas (Figure 6c).
