The role of meteoric water recharge in stimulating biogenic methane generation: A case study from the Tempoku Coal Field, Japan
Shuji Tamamura,Takuma Murakami,Noritaka Aramaki,Akio Ueno,Satoshi Tamazawa,Alam A.K.M. Badrul,Shofa Rijalul Haq,Toshifumi Igarashi,Hideo Aoyama,Shinji Yamaguchi,Katsuhiko Kaneko +10 more
TL;DR: In this paper, the authors conducted fieldwork in the Tempoku coal field, Japan and analyzed pore water in core samples and well water in boreholes for dissolved components and isotopic compositions.

TL;DR: In this paper, the authors investigated the origin of coalbed methane and water-dissolved gas from Kushiro coal mine and their formation environments and found a positive correlation between δD(CH4) of the sampled gas and the groundwater.

A Proposed Method to Estimate In Situ Dissolved Gas Concentrations in Gas-Saturated Groundwater.
TL;DR: The atmospheric sampling method is recommended for use where gas-saturated groundwater can be collected only ex situ under atmospheric conditions and overestimated the in situ dissolved methane concentrations, because the groundwater pressure at which bubbles appear was overestimated.

Variation in inorganic nitrogen and organic carbon concentrations in groundwater samples stored under cold and frozen conditions
TL;DR: In this paper, groundwaters in Shimonuma, located at Horonobe-cho, Hokkaido, were sampled at depths of 37 m, 45 m, and 75 m. During the approximately two-month-long storage period, the concentrations of NO3, NO2, and NH4 + fluctuated up to 20 times with a negative correlation between NO3 and NH 4 (correlation coefficient = 0.98).
