Nitrogen and oxygen isotopic studies of the marine nitrogen cycle
KL Casciotti - Annual review of marine science, 2016 - annualreviews.org
The marine nitrogen cycle is a complex web of microbially mediated reactions that control
the inventory, distribution, and speciation of nitrogen in the marine environment. Because …

Insights from fossil-bound nitrogen isotopes in diatoms, foraminifera, and corals
Nitrogen is a major limiting element for biological productivity, and thus understanding past
variations in nitrogen cycling is central to understanding past and future ocean …

The geochemistry of carbonate diagenesis: The past, present and future
PK Swart - Sedimentology, 2015 - Wiley Online Library
Stable carbon and oxygen isotopes (δ18O and δ13C values) and trace elements have been
applied to the study of diagenesis of carbonate rocks for over 50 years. As valuable as these …

Nitrogen isotopes in tooth enamel record diet and trophic level enrichment: Results from a controlled feeding experiment
Nitrogen isotope ratios (δ 15 N) are a well-established tool for investigating the dietary and
trophic behavior of animals in terrestrial and marine food webs. To date, δ 15 N values in …

Photosymbiosis and the expansion of shallow-water corals
Roughly 240 million years ago (Ma), scleractinian corals rapidly expanded and diversified
across shallow marine environments. The main driver behind this evolution is uncertain, but …

Carbon, nitrogen, and oxygen stable isotopes in modern tooth enamel: A case study from Gorongosa National Park, central Mozambique
The analyses of the stable isotope ratios of carbon (δ13C), nitrogen (δ15N), and oxygen
(δ18O) in animal tissues are powerful tools for reconstructing the feeding behavior of …

Deep-sea coral evidence for lower Southern Ocean surface nitrate concentrations during the last ice age
The Southern Ocean regulates the ocean's biological sequestration of CO2 and is widely
suspected to underpin much of the ice age decline in atmospheric CO2 concentration, but …

The survival, recovery, and diversification of metazoan reef ecosystems following the end-Permian mass extinction event
Abstract The Triassic Period records important ecological transitions in the aftermath of the
end-Permian mass extinction and is a key interval in the evolution of modern coral reefs …

Rapid shifts in circulation and biogeochemistry of the Southern Ocean during deglacial carbon cycle events
The Southern Ocean plays a crucial role in regulating atmospheric CO2 on centennial to
millennial time scales. However, observations of sufficient resolution to explore this have …

Laboratory assessment of the impact of chemical oxidation, mineral dissolution, and heating on the nitrogen isotopic composition of fossil‐bound organic matter
Fossil‐bound organic material holds great potential for the reconstruction of past changes in
nitrogen (N) cycling. Here, with a series of laboratory experiments, we assess the potential …
