TL;DR: In this paper, stable isotopic compositions of nitrate in precipitation and groundwater were determined for the island of Rishiri, Japan, so as to use the 17O anomalies (Δ17O) to trace the fate of atmospheric nitrate that had deposited onto the island ecosystem, which is a representative background forest ecosystem for eastern Asia.
Quantifying nitrate dynamics in an oligotrophic lake using Δ17O
TL;DR: In this article, stable isotopic compositions of nitrate, including the 17O anomalies (Δ17O), were determined twice in 1 yr (June and August 2007) in the oligotrophic water column of Lake Mashu, Japan.
Determination of total N 2 fixation rates in the ocean taking into account both the particulate and filtrate fractions
Uta Konno,Urumu Tsunogai,Daisuke D. Komatsu,S. Daita,Fumiko Nakagawa,Atsushi Tsuda,T. Matsui,Y.-J. Eum,Koji Suzuki +8 more
TL;DR: Using the 15N2 tracer method and high-sensitivity δ15N analytical systems, the authors determined N2 fixation rates for ocean samples by dividing them into particulate (> 0.7 μm) and filtrate (
Tracing atmospheric nitrate in groundwater using triple oxygen isotopes: evaluation based on bottled drinking water
TL;DR: In this paper, stable isotopic compositions of nitrate dissolved in 49 brands of bottled drinking water collected worldwide were measured, to trace the fate of atmospheric nitrate (NO3− atm) that had been deposited into subaerial ecosystems, using the 17O anomalies (Δ17O) of Nitrate as tracers.
