Fig. 10From: High-resolution mapping and time-series measurements of 222Rn concentrations and biogeochemical properties related to submarine groundwater discharge along the coast of Obama Bay, a semi-enclosed sea in JapanAs in Fig. 8 but for a tidal level (m) and the concentrations of b 222Rn (dpm/L), phosphorous (μM), nitrate (μM), and silicate (μM). Values on the X-axes of the plots in a indicate the time (h) of water sampling for nutrient analysis, and those on the Y-axes of the plots are the tide levels at those timesBack to article page
