A complex web of interactions between geological features including volcanoes, subsurface mantle, oceans and the atmosphere created the chemical mixture necessary for early life to oxygenate our ...

2007). The coupled biogeochemical cycles of carbon (C) and nitrogen (N) are strongly influenced by soil erosion as it affects their fluxes in and out of the soil system, storage, distribution ...

Aa Aa Aa Biogeochemical cycles describe pathways by which chemical elements move through both biotic (the biosphere) and abiotic compartments (the atmosphere, hydrosphere, and lithosphere ...

Glaciers carry unique organic carbon fingerprints that reflect geography and pollution, influencing ecosystems downstream.

Glaciers, those massive rivers of ice that carve through mountain landscapes, have long been viewed as frozen giants, impervious to change. However, a groundbreaking study has uncovered a startling ...

This daily feast-and-famine cycle in oxygen availability created an intense physiological challenge for early animals, forcing them to develop adaptations to handle fluctuations in nutrients. For ...

I am a broadly trained biogeochemist who uses organic and stable isotope geochemical tools to study the co-evolution of biology, biogeochemical cycles and climate. My research studies the interplay ...

My research focuses on using stable isotopes to better understand the biogeochemical cycle of modern and past oceans. More specifically, using the isotope N taken from coral to correlate the ...

Microalgae, belonging to the diverse group of photosynthetic microorganisms, play pivotal roles in global ecosystems and biogeochemical cycles. They contribute significantly to carbon fixation and ...
