The toxic metal mercury is present only at trace levels in the ocean, but it accumulates in fish at concentrations high enough to pose a threat to human and environmental health. Human activity has dr...
In 1896, Arrhenius provided the first roughly quantitative sense of the plausible magnitude of human-induced changes in the concentration of CO2 in the atmosphere. Since then, all chemists could be aw...
Deep Ocean Carbonate Chemistry and Glacial-Interglacial Atmospheric CO2 Changes
Deep Ocean Carbonate Chemistry Glacial-Interglacial Atmospheric CO2
2015/7/17
Changes in deep ocean carbonate chemistry have profound implications for glacial-interglacial atmospheric CO2 changes. Here, we review deep ocean carbonate ion concentration ([CO32–]) changes based on...
A Time-Series View of Changing Ocean Chemistry Due to Ocean Uptake of Anthropogenic CO2 and Ocean Acidification
Time-Series View Changing Ocean Chemistry Due Ocean Uptake Anthropogenic CO2 Ocean Acidification
2015/7/17
Sustained observations provide critically needed data and understanding not only about ocean warming and water cycle reorganization (e.g., salinity changes), ocean eutrophication, and ocean deoxygenat...
Persistent Organic Pollutants (POPs),Polycyclic Aromatic Hydrocarbons (PAHs),and Plastics:Examples of the Status, Trend,and Cycling of Organic Chemicals of Environmental Concern in the Ocean
Persistent Organic Pollutants (POPs) Polycyclic Aromatic Hydrocarbons (PAHs) Plastics:Examples of the Status Trend Cycling Organic Chemicals Environmental Concern in the Ocean
2015/7/17
Four decades of research have provided a reasonable understanding of the outline of the biogeochemical cycles of persistent organic pollutants (POPs) and polycyclic aromatic hydrocarbons (PAHs) in coa...
Ocean Acidification:The Role of CO2.
The Moorea Coral Reef Long Term Ecological Research program affords a unique opportunity to study the implications of ocean acidification (OA) for coral reefs, as ongoing ecological and physical monit...
Diversity of Hydrothermal Systems on Slow Spreading Ocean Ridges
Slow Spreading Ocean Ridges Hydrothermal Systems
2015/7/16
The global mid-ocean ridge system spreads over a spectrum of rates, and oceanic crust formed at slow and ultra-slow spreading ridges (< 40 mm yr–1) differs from the more "ideal" layered structure form...
Could we, should we, knowingly pollute
the world ocean? It’s easy to think that
the ocean is awfully big, and maybe no
one will notice. Unfortunately, it’s too
late to debate this ethical issu...
Ocean Acidification
Ocean Acidification
2015/7/14
This new book edited by Jean-Pierre Gattuso and Lina Hansson is a timely, interdisciplinary look at the phenomenon of ocean acidification, which refers broadly to changes in seawater chemistry caused ...
Applications of Satellite-Derived Ocean Measurements to Tropical Cyclone Intensity Forecasting
Satellite-Derived Ocean Tropical Cyclone Intensity Forecasting
2015/7/6
Sudden tropical cyclone (TC) intensification has been linked with high values of upper ocean heat content contained in mesoscale features, particularly warm ocean eddies, provided that atmospheric con...
At different times of the year, prevailing winds blow into Bermuda from open ocean to the south or from the continental United States — an ideal laboratory for studying pollution generated by human ac...
The largest migration on the planet is the movement of small animals from the surface of the open ocean, where they feed on plants under cover of darkness, to the sunless depths where they hide from p...
Scientists have created a new map of the world's seafloor, offering a more vivid picture of the structures that make up the deepest, least-explored parts of the ocean.
Study resolves controversy over nitrogen's ocean 'exit strategies'
Study resolves controversy over nitrogen's ocean 'exit strategies'
2014/4/16
A decades-long debate over how nitrogen is removed from the ocean may now be settled by new findings from researchers at Princeton University and their collaborators at the University of Washington.
