Fig. 1: Two-decade trends in oceanic factors and local groundwater dynamics.

From: Coastal groundwater salinization impairs tree carbon–water balance

Fig. 1

Time series of (a) atmospheric CO2 concentrations, b globally averaged oceanic evaporation, c mean annual temperature (MAT), d regional sea level (a.m.s.l.), e the PC1 scores of plot-level groundwater properties, and f the PC2 scores of plot-level groundwater properties are shown. Note that groundwater PC1 is primarily contributed by magnesium, calcium, conductivity, sodium, and chloride of groundwater, while groundwater PC2 summarizes the variations in water level depth, NH4+, pH, and NO3−.
