a–d Depth concentration profiles of nutrients (SO42–, NH4+, NO3– and NO2–) in porewater (0 − 26 cmbsf, n = 231) collected from Lingshui, Haima and Site F cold seeps. e, f Depth profiles of N2 and their δ15N values in the headspace gas of Site F-10 and Site F-14 cold seep sediments. g–i Depth profiles of TOC, TN, and TOC: TN in cold seep and non-seep sediments (0 − 36 cmbsf, n = 209) collected from Lingshui, Haima, Site F, Shenhu, and Qiongdongnan. j–m Depth concentration profiles of dissolved metals (Cu2+, Zn2+, Ca2+, and Fe2+) in porewater (0 − 26 cmbsf, n = 231) collected from Lingshui, Haima and Site F cold seeps. Black, green, orange, dark blue, and red points represent the concentration of geochemical parameters in Lingshui, Haima, Site F, Shenhu, and Qiongdongnan, respectively.
