New research maps areas most vulnerable to ocean acidification

New NOAA-led research maps the distribution of aragonite saturation state in both surface and subsurface waters of the global ocean and provides further evidence that ocean acidification is happening on a global scale. The ...

Study shows oceanic phytoplankton declines in northern hemisphere

The world's oceans have seen significant declines in certain types of microscopic plant-life at the base of the marine food chain, according to a new NASA study. The research, published Sept. 23 in Global Biogeochemical Cycles, ...

Boreal peatlands not a global warming time bomb

To some scientists studying climate change, boreal peatlands are considered a potential ticking time bomb. With huge stores of carbon in peat, the fear is that rising global temperatures could cause the release of massive ...

Estimates of anthropogenic nitrogen in the ocean may be high

Inundation of nitrogen into the atmosphere and terrestrial environments, through fossil fuel combustion and extensive fertilization, has risen tenfold since preindustrial times according to research published in Global Biogeochemical ...

Ocean carbon uptake more variable than thought

The Earth's oceans are thought to have taken up about one quarter of the carbon dioxide (CO2) that humans pumped into the atmosphere in the past 2 decades. While this drives acidification and has consequences for sea life, ...

Researchers track ammonium source in open ocean

To understand the extent to which human activities are polluting Earth's atmosphere and oceans, it's important to distinguish human-made pollutants from compounds that occur naturally. A recent study co-authored by a Brown ...

Ocean food web is key in the global carbon cycle

Nothing dies of old age in the ocean. Everything gets eaten and all that remains of anything is waste. But that waste is pure gold to oceanographer David Siegel, director of the Earth Research Institute at UC Santa Barbara.
