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 ...

Quantitative Resolution of Phosphorus Sources in an Agricultural Watershed of Southern China: Application of Phosphate Oxygen Isotopes and Multiple Models

Agronomy
Phosphorus is the primary contributor to eutrophication in water bodies, and identifying phosphorus sources in rivers is crucial for controlling phosphorus pollution and subsequent eutrophication.

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.

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.

Autoradiography of Pi Distribution in Barley Seedlings

Bio-Protocol, 2014
Phosphorus-32 and Phosphorus-33 are radioisotopes of phosphorus. These isotopes are used to trace ionic phosphorus and phosphorus compounds. This protocol is used to follow the movement of inorganic phosphate (PO43-) from a leaf tip to the rest of the ...

Eutrophication-Driven Deoxygenation in the Coastal Ocean [PDF]

Oceanography, 2014
Human activities, especially increased nutrient loads that set in motion a cascading chain of events related to eutrophication, accelerate development of hypoxia (lower oxygen concentration) in many areas of the world's coastal ocean. Climate changes and

Changes in shelf phosphorus burial during the Hirnantian glaciation and its implications [PDF]

Estonian Journal of Earth Sciences, 2023
The Late Ordovician mass extinction occurred during an icehouse interval, accompanied by the glaciation of the supercontinent Gondwana, which was located at the South Pole at that time.
