Higher levels of carbon dioxide (CO2) enhanced growth of a green seaweed (Ulva rigida). (Laboratory study)
Aerobic scope and cardiac performance of Atlantic halibut increased following 14–16 weeks exposure to elevated temperatures and even more so in combination with CO2-acidified seawater. However, the increase does not translate into improved growth. Instead, long-term exposure to CO2-acidified seawater reduces growth at temperatures that are frequently encountered by this ...
This study used two methods to estimate the exchange of carbon dioxide between the atmosphere and ocean.
Deep-water prawns (Pandalus borealis) exposed to severely acidified seawater (pH 6.86) for 16 days were able to compensate by accumulate buffering bicarbonate ions at levels comparable to those reported for shallow-living decapod crustaceans. (Laboratory study)
The Arctic spider crab (Hyas araneus) appears to have a threshold of ocean acidification beyond which it fails to acclimate. In a 10-week experiment, it had a limited ability to adjust to effects of ocean acidification with and without also experiencing a warmer temperature. (Laboratory study)
A species of phytoplankton changed how it used carbon and energy when it was exposed to higher CO2 levels. The effects differed depending on whether the CO2 level change happened over 15-16 generations versus 33-57 generations. (Laboratory study)
When the Gulf toadfish was exposed to levels of ocean acidification that are projected to occur by 2300, it lost greater amounts of bicarbonate ions through its intestine. (Laboratory study)
Blue mussels and ocean quahogs from the Baltic Sea appeared to tolerate wide ranges of seawater temperature and ocean acidification over a period of 13 weeks. (Laboratory study)
Under conditions expected in the 21st century, global warming and ocean acidification will cause corals to become increasingly rare on reef systems. This review presents future scenarios for coral reefs that predict increasingly serious consequences for reef-associated fisheries, tourism, coastal protection, and people.
When grown under ocean acidification conditions, a non-calcifying seaweed (Chondrus crispus) grew to cover more area, while a calcifying alga (Corallina officinalis) decreased in the area it covered. (Laboratory experiment)
