Hydrology and riparian forests drive carbon and nitrogen supply and DOC : NO3 stoichiometry along a headwater Mediterranean stream [PDF]

open access: yesHydrology and Earth System Sciences, 2022
In forest headwater streams, metabolic processes are predominately heterotrophic and depend on both the availability of carbon (C) and nitrogen (N) and a favourable C:N stoichiometry.

Modeling oceanic nitrate and nitrite concentrations and isotopes using a 3-D inverse N cycle model [PDF]

open access: yesBiogeosciences, 2019
Nitrite (NO2-) is a key intermediate in the marine nitrogen (N) cycle and a substrate in nitrification, which produces nitrate (NO3-), as well as water column N loss processes denitrification and anammox.

Research on power quality comprehensive treatment for coal mine

open access: yesGong-kuang zidonghua, 2016
For problems of harmonics pollution and voltage fluctuation existed in power quality of coal mine, a power quality comprehensive treatment method based on SVG for coal mine was proposed. The method uses orthogonal transformations theory to realize direct

Isotopic signatures of major methane sources in the coal seam gas fields and adjacent agricultural districts, Queensland, Australia [PDF]

open access: yesAtmospheric Chemistry and Physics, 2021
In regions where there are multiple sources of methane (CH4) in close proximity, it can be difficult to apportion the CH4 measured in the atmosphere to the appropriate sources.

On the potential fingerprint of the Antarctica ozone hole in ice-core nitrate isotopes: a case study based on a South Pole ice core [PDF]

open access: yesAtmospheric Chemistry and Physics, 2022
Column ozone variability has important implications for surface photochemistry and the climate. Ice-core nitrate isotopes are suspected to be influenced by column ozone variability and δ15N(NO3-) has been sought to serve as a proxy of column ozone ...

Impacts of post-depositional processing on nitrate isotopes in the snow and the overlying atmosphere at Summit, Greenland [PDF]

open access: yesThe Cryosphere, 2022
The effect of post-depositional processing on the preservation of snow nitrate isotopes at Summit, Greenland, remains a subject of debate and is relevant to the quantitative interpretation of ice-core nitrate (isotopic) records at high snow accumulation ...

Inter-annual variability of the global terrestrial water cycle [PDF]

open access: yesHydrology and Earth System Sciences, 2020
Variability of the terrestrial water cycle, i.e. precipitation (P), evapotranspiration (E), runoff (Q) and water storage change (ΔS) is the key to understanding hydro-climate extremes.
