Ocean acidification refers to the lowering of the ocean’s pH due to the uptake of anthropogenic CO2 from the atmosphere. Coral reef calcification is expected to decrease as the oceans become more acidic. Dissolving calcium carbonate (CaCO3) sands could greatly exacerbate reef loss associated with reduced calcification but is presently poorly ...
It has been speculated that the partial pressure of carbon dioxide (pCO2) in shelf waters may lag the rise in atmospheric CO2. Here, we show that this is the case across many shelf regions, implying a tendency for enhanced shelf uptake of atmospheric CO2. This result is based on analysis ...
BACKGROUND Oxygen concentrations in both the open ocean and coastal waters have been declining since at least the middle of the 20th century. This oxygen loss, or deoxygenation, is one of the most important changes occurring in an ocean increasingly modified by human activities that have raised temperatures, CO2 levels, and nutrient ...
Public support for carbon emissions mitigation is crucial to motivate action to address global issues like climate change and ocean acidification (OA). Yet in the public sphere, carbon emissions mitigation policies are typically discussed in the context of climate change and rarely in the context of OA or other global ...
Accelerated oxygen loss in both coastal and open oceans is generating complex biological responses; future understanding and management will require holistic integration of currently fragmented oxygen observation and research programmes.
Exponentially rising CO2 (currently ~400 µatm) is driving climate change and causing acidification of both marine and freshwater environments. CO2 directly affects acid–base and ion regulation, respiratory function and aerobic performance in aquatic animals. Elevated CO2 projected for end of this century (e.g. 800–1000 µatm) can also impact physiology, and have substantial ...
The NOAA Ocean Acidification Program (OAP) was established in May 2011, by the Federal Ocean Acidification Research and Monitoring (FOARAM) Act. This program aims to coordinate research, monitoring, and other activities to improve our understanding of how (and how fast) the chemistry of the ocean is changing, how variable that change ...
