Seafood lovers are set to see less shellfish, salmon and other fish on their dinner plates as climate change warms the oceans and makes them more acidic. The findings from a series of studies out this week suggest rising greenhouse emissions from the burning of fossil fuels are adding stress to oceans that are already […]
Ocean acidification is changing the carbonate system of the world’s oceans and has been driving all marine organisms to live in increasingly acidic environments. Tigriopus japonicus is an ideal standard test animal in sea water. In the...Show More Summary

If you haven't seen this then it's a must watch. If you have, then watch it again! The Lower Snake dams "are largely responsible for the destruction of the salmon runs that we used to see all the way up into the Rocky Mountains in Idaho." – Bruce Babbitt, former U.S. Show More Summary
Sleek and beautiful, leopard sharks are built for life on the seafloor. Their mouths are on the flat underside of their heads and open downward allowing them to graze on food buried in the sand. Learn more about these cool creature...
Saturday, July 4th...another 'whale wake up call'...in the form of echolocation clicks over the Lime Kiln (3:45 a.m.) and then the Orca Sound (4:40 a.m.) hydrophones...too dark, too tired, but I got ready, just in case whoever it was decided to come back down island...I wasn't going to miss them this time!'...at 6:17 a.m. Show More Summary
Time is rapidly running out for the world’s oceans and the creatures that live in them as the Earth’s climate continues to warm, say scientists. Only ‘immediate and substantial’ reductions in greenhouse gas emissions can hope to prevent ‘massive’ impacts on marine ecosystems, warn the experts. Researchers compared the fate of the oceans under two […]
A new paper just published in Science summarizes the projected impacts of climate change on the world’s oceans, and consequently on humans and our economy. The study concludes that global warming beyond the international limit of 2°C above pre-industrial temperatures would pose serious threats to marine ecosystems and their millions of human dependents. It builds […]
Scientists have warned that marine life will be irreversibly changed unless CO2 emissions are drastically cut. Writing in Science, experts say the oceans are heating, losing oxygen and becoming more acidic because of CO2. They warn that the 2C maximum temperature rise for climate change agreed by governments will not prevent dramatic impacts on ocean […]
Over the last two centuries, human activities have led to an unprecedented rate of carbon input into the atmosphere and oceans resulting in an alarmingly rapid decline in surface ocean pH, a process referred to as ocean acidification (OA). This process is leading to an observed decline in the carbonate ion concentrations ([CO32-]) in seawater […]
Ocean acidification and hypoxic events are an increasing worldwide problem, but the synergetic effects of these factors are seldom explored. However, this synergetic occurrence of stressors is prevalent. The coastline of Chile not only suffers from coastal hypoxia but the cold, oxygen-poor waters in upwelling events are also supersaturated in CO2, a study site to […]
The tropical echinoid Echinometra viridis was reared in controlled laboratory experiments at temperatures of approximately 20°C and 30°C to mimic winter and summer temperatures and at carbon dioxide (CO2) partial pressures of approximately 487 ppm-v and 805 ppm-v to simulate current and predicted-end-of-century levels.

Marine scientists broadly agree on which major processes influence the sustainability of marine environments worldwide. Recent studies argue that such shared perceptions crucially shape scientific agendas and are subject to a confirmation bias. Show More Summary
Environmental changes resulting from anthropogenic CO2 emissions occur at global and local levels and have potentially harmful effects, particularly for calcifying taxa in the marine environment. A time series of pteropod abundance covering the period 1967-2003 was isolated from the Point B (northwestern Ligurian Sea) zooplankton time series. Show More Summary

Common, but with uncommon beauty In its everyday plumage, the dunlin (Calidris alpina) is a dull grayish, brownish speckled shorebird that’s a common sight across the United States, where it winters on both east and west coasts and into Alaska. Show More Summary
Using empirical analyses of the effects of global climate change (GCC) and ocean acidification (OA) on the survival and calcification of early life stages of Pocillopora damicornis, we employed a demographic approach to forecast the consequences of GCC and OA on the population dynamics of this coral. We constructed a size-based demographic model using life-history […]
Ocean acidification negatively affects many marine species and is predicted to cause widespread changes to marine ecosystems. Similarly, freshwater ecosystems may potentially be affected by climate-change-related acidification; however, this has received far less attention. Show More Summary
