Soil profile and grain-size distribution from the spring-monitoring well (Figure 1). Left: photograph of the 0–1.4 m core, showing the oxidized, salt-bearing clay (0–0.3 m), the mottled redox-transition interval (roughly 0.3–0.4 m), and the underlying dark, reduced euxinic sands. Right: clay, silt, and sand fractions for each sampled depth interval.
