Hydrocarbons and petroleum are almost synonymous in environmental science. Oil reserves account for nearly all the hydrocarbons we know. But the few hydrocarbons that trace their origin to biological ...
Tiny Shells Indicate Big Changes to Global Carbon Cycle
Tiny Shells Indicate Big Changes Global Carbon Cycle
2017/7/20
Experiments with tiny, shelled organisms in the ocean suggest big changes to the global carbon cycle are underway, according to a study from the University of California, Davis. For the stud...
Energy is the most important requirement for life. It can be acquired by harvesting electrons flowing naturally from reduced to oxidized inorganic compounds (lithotrophy) or organic compounds (organot...
Of all the biogeochemical cycles, nitrogen is the one most intimately and thoroughly associated with microbes. Essential and unique steps in the nitrogen cycle are performed by a wide array of bacteri...
Phosphorus (P) is fundamental to life, and years of study in marine systems have built a broad understanding of the marine P cycle. Various aspects of marine P biogeochemistry have been reviewed previ...
Understanding the Role of the Biological Pump in the Global Carbon Cycle:An Imperative for Ocean Science
Biological Pump Global Carbon Cycle Ocean Science
2015/7/20
Anthropogenically driven climate change will rapidly become Earth's dominant transformative influence in the coming decades. The oceanic biological pump—the complex suite of processes that results in ...
Humans concerned about climate change are working to find ways of capturing excess carbon dioxide (CO2) from the atmosphere and sequestering it in the Earth. But Nature has its own methods for the rem...
A new study reports that anammox, a key process in the nitrogen cycle, is barely present in Narragansett Bay even though it’s a major factor just a little farther out into Rhode Island Sound. Scientis...
Carbon cycling hysteresis in permeable carbonate sands over a diel cycle: Implications for ocean acidification
Carbon cycling hysteresis permeable carbonate sands over a diel cycle ocean acidification
2014/4/2
Dissolved inorganic carbon, dissolved oxygen, H+, and alkalinity fluxes from permeable carbonate sediments at Heron Island (Great Barrier Reef) were measured over one diel cycle using benthic chambers...

Photoprotection mechanisms against ultraviolet radiation in Heterocapsa sp. (Dinophyceae) are influenced by nitrogen availability: Mycosporine-like amino acids vs. xanthophyll cycle
Heterocapsa sp Photoprotection mechanisms
2014/4/16
The photoprotective and acclimation capacity against ultraviolet radiation (UVR) was assessed for the
dinoflagellate Heterocapsa sp. We examined the effect of UVR and N availability on photosynthetic...
