资源简介：
Two field campaigns were conducted in April (dry season) and August 2017 (wet season). A total of 514 water samples (83 river samples, 91 groundwater samples and 340 seawater samples) were collected to analyze DIC, DOC, and TA. Our observations cover the entire Bohai Sea and its coastline to capture the full range of hydrogeological conditions. Saline groundwater samples were extracted from the intertidal zone at depths of 0.5–2 m below the ground surface using push-point sampler (MHE instruments) and a peristaltic pump, while fresh groundwater samples were collected from inland monitoring wells at ~10 m. Seawater, fresh river water and estuary water samples were collected ~ 0.5 m below the surface. DOC samples underwent filtration through 0.7 µm GF/F filters and acidification to pH
