Global Ocean Acidification
As carbon concentrations in the atmosphere increase, so do concentrations in the ocean, with resultant acidification as a natural chemical process.

Uptake of Carbon Dioxide from the Atmosphere
Arctic marine systems currently provide a substantial carbon sink but the continuation of this service depends critically on arctic climate change impacts on ice, freshwater inputs, and ocean acidification.

BSR ecosystem area where acidification and eutrophication exceeds critical loads
Graphics from the year 2000 Baltic 21 biannual indicator-based status report on sustainable development in the Baltic Sea Region (Baltic 21 Series No 1/2000). This graphic shows BSR ecosystem area where acidification and...

Cumulative impacts on the marine environment
Climate change may, through effects on ocean currents, elevated sea temperatures, coral bleaching, shifts in marine life, ocean acidification and much more severely exacerbate the combined actions of accelerating coastal...

Distribution of coldwater and tropical coral reefs
Coral reefs are marine ridges or mounds, which have formed over millennia as a result of the deposition of calcium carbonate by living organisms, predominantly corals, but also a rich diversity of other organisms such as...

Acidification due to climate change - impacts for oceans and coral reefs
As carbon concentrations in the atmosphere increase from land use changes and emissions from fossil fuels - so do concentrations in the ocean, with resultant acidification as a natural chemical process. The skeletons of ...

Wetlands in the Baltic Sea drainage basin
Percentage of wetlands out of total land area (by grid cell) for the Baltic Sea drainage basin. Wetlands acts as buffers in cases such as antropogenic nutrient releases (which leads to eutrophication) and acidification. ...

Coldwater coral reefs, distribution
Scientists are just beginning to learn about the many species in the remote, deep waters of the polar oceans. Corals, for example, are not limited to the warm, shallow waters of the tropics. They also exist in many cold,...
