Applicability of d-excess and 17O-excess as groundwater tracers for determination of recharge area

Autor: Isao Machida, Masahiko Ono, Takafumi Kamitani, Yasuhide Muranaka

Publikováno v: Hydrogeology Journal. 30:2027-2041

Methods to determine the recharge elevation of groundwater using the altitude effect of δD and δ18O have been extensively applied in hydrogeological investigations. The secondary parameter d-excess has also been used as a groundwater tracer. In thi

Noble gases dissolved in groundwater have been used to evaluate characteristics such as origin, residence time and recharge temperature. Although obtaining samples without degassing is highly desired, in certain cases, degassing during sampling is un

Groundwater movement through the slope area of Mt. Fuji to the coastal area of Suruga Bay (central Japan) was investigated using spatially dense geochemical data, as a case study for elucidating the groundwater flow system in a stratovolcano adjacent

Sea surficial waves as a driving force that enhances the fresh shallow coastal groundwater flux into the oceans

Autor: Kiyoshi Takikawa, Yaser Nikpeyman, Kimpei Ichiyanagi, Takahiro Hosono, Jun Shimada, Heejun Yang, Masahiko Ono

Publikováno v: Environmental Earth Sciences. 78

Submarine groundwater discharge (SGD) is a process through which groundwater and solutes are transferred from coastal aquifers into the oceans. Generally, the SGD is composed of two basic components: (1) fresh groundwater, FSGD; and (2) recirculated
