Dataset for tracing phosphorus sources by the oxygen isotopes of phosphate

Data in Brief, 2022
Phosphorus is an essential nutrient for the growth of marine life. Especially in the East China Sea (ECS) where phosphorus is limited compared to the rest of China's sea, the external input of phosphorus can cause changes in primary productivity, and ...

Swiss data quality: augmenting CAMELS-CH with isotopes, water quality, agricultural and atmospheric data [PDF]

Scientific Data
Despite the growth of large-sample hydrology (LSH) datasets, water quality data remain scarce. Here, we introduce CAMELS-CH-Chem, an extension of CAMELS-CH (Catchment Attributes and Meteorology for Large-sample Studies in Switzerland), incorporating up ...

Enhanced erosion by continental arc volcanism as a driver of the Cambrian Explosion [PDF]

Nature Communications
Nutrient availability and rising oxygen levels are important for the Cambrian Explosion (~540–515 Ma), both of which can be satisfied via enhanced weathering driven by climate and tectonics.

Earth system instability amplified biogeochemical oscillations following the end-Permian mass extinction [PDF]

Nature Communications
After the end-Permian mass extinction, the Earth system underwent extreme ecological and environmental fluctuations, including high temperatures, recurrent oceanic anoxia, and carbon cycle oscillations as demonstrated by the geochemical isotope proxy ...

A dual isotopic approach using radioactive phosphorus and the isotopic composition of oxygen associated to phosphorus to understand plant reaction to a change in P nutrition [PDF]

Plant Methods, 2017
Background Changing the phosphorus (P) nutrition leads to changes in plant metabolism. The aim of this study was to investigate how these changes are reflected in the distribution of 33P and the isotopic composition of oxygen associated to P (δ18OP) in ...

Stability of the marine nitrogen cycle over the past 165 million years [PDF]

Nature Communications
Nitrogen and phosphorus are the two macro-nutrients that limit biological productivity in the ocean. While the supply of P depends on geological processes, N is biologically supplied from an inexhaustible atmospheric source, but can be limited by micro ...

Phosphorus dynamics during early soil development in a cold desert: insights from oxygen isotopes in phosphate [PDF]

SOIL, 2022
At the early stages of pedogenesis, the dynamics of phosphorus (P) in soils are controlled by microbial communities, the physicochemical properties of the soil and the environmental conditions.

Assessing the contribution of atmospheric transport to phosphorus in the East China Sea using the oxygen isotope in phosphate

Frontiers in Marine Science, 2023
Phosphorus is an important nutrient for the growth of marine organisms. External inputs of phosphorus can lead to changes in the primary productivity and may trigger harmful algal blooms.

Nutrient dynamics in temperate European catchments of different land use under changing climate

Journal of Hydrology: Regional Studies, 2023
Study region: Vltava River basin, South Bohemian Region of the Czech Republic, Central Europe Study focus: To understand the dynamics of nutrients (nitrogen, phosphorus, and organic carbon) in streams, we combined hydrometeorological, hydrochemical and ...
