Seasonal and spatial variation in the stable isotopic composition (δ18O and δD) of precipitation in south Florida [PDF]

, 2008
Precipitation data collected from five sites in south Florida indicate a strong seasonal and spatial variation in δ18O and δD, despite the relatively limited geographic coverage and low-lying elevation of each of the collection sites.

Estimation of Groundwater Residence Time Using the 36Cl Bomb Pulse [PDF]

, 2011
We propose a methodology for estimating the residence time of groundwater based on bomb-produced 36Cl. Water samples were collected from 28 springs and 2 flowing wells located around Mt. Fuji, Central Japan.

Preparation and Certification of Reference Materials for Hydrogen and Oxygen Isotopes in Water

Yankuang ceshi, 2013
Certified reference materials of water for stable hydrogen and oxygen isotopes were developed and have been used for more than 30 years. However, they no longer meet the requirements for newly developed technologies. New reference materials of water have

Sub-Zero Alteration in an Isotopically Heavy Brine Preserved in a Pristine H Chondrite Xenolith [PDF]

Introduction: Brecciated H chondrites host a variety of xenoliths, including unshocked, phyllo- silicate-rich carbonaceous chondrites (CCs). The brecciated H chondrite Zag (H3-6) is one of two chondrites to host macroscopic (1 - 5mm), xenolithic crystals
