The seabed plays a key role in the marine carbon cycle as a) the terminal location of aerobic
oxidation of organic matter, b) the greatest anaerobic bioreactor, and c) the greatest …

Microbial activity is a fundamental component of oceanic nutrient cycles. Photosynthetic
microbes, collectively termed phytoplankton, are responsible for the vast majority of primary …

Changing climate in northern regions is causing permafrost to thaw with major implications
for the global mercury (Hg) cycle. We estimated Hg in permafrost regions based on in situ …

The Southern Ocean plays a critical role in regulating global climate as a major sink for
atmospheric carbon dioxide (CO2), and in global ocean biogeochemistry by supplying …

Turbulent mixing from breaking oceanic internal waves drives a vertical transport of water,
heat and other climatically important tracers in the ocean, thereby playing an important role …

Mercury is a toxic, bioaccumulating trace metal whose emissions to the environment have
increased significantly as a result of anthropogenic activities such as mining and fossil fuel …

Changes in oceanic primary production, linked to changes in the network of global
biogeochemical cycles, have profoundly influenced the geochemistry of Earth for over 3 …

Rising atmospheric carbon dioxide (CO2) concentrations over the past two centuries have
led to greater CO2 uptake by the oceans. This acidification process has changed the …

Abstract The Marine Biogeochemistry Library (MARBL) is a prognostic ocean
biogeochemistry model that simulates marine ecosystem dynamics and the coupled cycles …

Iron is an essential nutrient that regulates productivity in~ 30% of the ocean. Compared with
deep (> 2000 meter) hydrothermal activity at mid-ocean ridges that provide iron to the …
