Global Biogeochemical Cycles features research on regional to global biogeochemical interactions, as well as more local studies that demonstrate fundamental implications for biogeochemical processing at regional or global scales. Published papers draw on a wide array of methods and knowledge and extend in time from the deep geologic past to recent historical and potential future interactions. This broad scope includes studies that elucidate human activities as interactive components of biogeochemical cycles and physical Earth Systems including climate. Authors are required to make their work accessible to a broad interdisciplinary range of scientists.

From glacier ice, a wealth of scientific data

Perched next to a river near a glacier's edge in Greenland, Penn biogeochemist Jon Hawkings and Jack Murphy, senior research coordinator in Hawkings' lab, scooped up samples of frigid meltwater, careful to seal the bottles ...

Tropical wetlands emit more methane than previously thought

Since 2007, the world's atmospheric methane concentration has risen at an accelerated rate, but scientists aren't exactly sure why. This is a problem, because methane is a particularly potent greenhouse gas. It has more than ...

The seasonality of oceanic carbon cycling

The ebb and flow of carbon within Earth's systems are complex and ever-moving occurrences. Carbon is a nomadic element, traveling between the atmosphere, ocean, and the soil, rock, and ice of the planet, changing forms along ...

Scientists build new atlas of ocean's oxygen-starved waters

Life is teeming nearly everywhere in the oceans, except in certain pockets where oxygen naturally plummets and waters become unlivable for most aerobic organisms. These desolate pools are "oxygen-deficient zones," or ODZs. ...

Earth's natural carbon sinks hold vital power in climate fight

Earth's vast habitats from the poles to the equator have robust capacity to remove carbon dioxide from the atmosphere due to previously undiscovered rock nitrogen weathering reactions that distribute natural fertilizers ...
