Note: carbon-cycle estimation: a plea for measurement of ocean carbon dioxide concentrations

Unless an effort is made to measure the carbon dioxide content of the oceans, the ability of researchers to distinguish between absorption by oceanic and by biotic sinks related to carbon emissions will remain imperfect. This uncertainty presently limits the ability of policy-makers to set a carbon emissions target fully consistent with that for carbon dioxide concentrations.Keywords: ...

TOC and TN Measurements of Seawater

For pollution control of the ocean and in the research of the ocean environment, the measurement of total organic carbon (TOC) is regarded as an important index of organic contaminants contained in seawater. At the same time, the measurement of total nitrogen (TN), which is known to cause eutrophication, is also attracting attention for environmental pollution control and in ecological ...

Antarctica is changing rapidly. Meet the researchers working at the edge of the world.

Did you know the National Science Foundation through the United States Antarctic Program sends roughly 3,000 people to Antarctica annually to conduct research and provide support services to the researchers (you can look for openings here if you’re dreaming about ditching your desk job)? And the U.S. is just one country among many conducting ongoing polar research each year. This stunning ...

Long-term impacts of deep-sea mineral mining

A new international study has demonstrated that deep-sea nodule mining will cause long-lasting damage to deep-sea life. This study, led by scientists at the National Oceanography Centre (NOC), was the first to review all the available information on the impacts of small-scale sea-floor disturbances simulating mining activity. It found clear impacts on marine ecosystems from deep-sea nodule mining ...

Abrupt Impacts of Climate Change: Anticipating Surprises

Both abrupt changes in the physical climate system and steady changes in climate that can trigger abrupt changes in other physical, biological, and human systems present possible threats to nature and society. Abrupt change is already underway in some systems, and large scientific uncertainties about the likelihood of other abrupt changes highlight the need for further research. However, with ...

Nutrient dynamics in European water systems - the management perspective emerging from ELOISE, a European cluster of land - ocean interaction studies

The European ELOISE (European Land Ocean Interaction Studies) cluster (>60 projects) is the world's largest research initiative on land - ocean interactions. Beside its scientific goals, ELOISE is also meant to contribute directly to coastal zone management and thus to European coastal policy. Most of the ELOISE results have been gathered in digests that are made available on the Internet to all ...

Shellfisheries: Time to prepare for ocean acidification

Both physical and social factors must be considered as coastal communities brace for an uncertain future. Oceans are gradually becoming warmer and more acidic as more carbon dioxide enters the atmosphere — two shifts that are altering the economic foundations of many coastal regions. In a new study published in Nature Climate Change, we and our colleagues set out to identify hot spots ...

Australian desalination plant attracts fish

With growing populations and climate uncertainty, water security is a global concern. Many nations operate desalination plants, which remove salt from seawater to make it drinkable. These facilities typically discharge excess salt as hypersaline brine back into the ocean, with uncertain ecological effects. Now, researchers in Environmental Science & Technology report that a large desalination ...

Ocean science for sustainable development: Facts and figures

Sarah Grimes explores why we need good ocean monitoring, how to get it, and why it still fails Small Island Developing States. Oceans are a critically important component of the Earth system, supporting ecosystem and human health. They regulate the weather and climate; are essential for producing freshwater; and soak up carbon. They also provide food and other resources, trade and migration ...

`South Asian monsoon variations hard to fathom`

Understanding how the South Asian monsoon will change in response to global warming and resolving the uncertainties in projected changes are ‘demanding tasks’ for climate science, a review says. Current state-of-the-art general circulation models have difficulty simulating the regional distribution of monsoon rainfall, the 24 June review in Nature Climate Change says. The vagaries ...

Extreme Weather In A Changing Climate: Asking The Right Questions

When a deadly heat wave lingers for an especially long time; when a hurricane makes landfall with particular ferocity; or when droughts, winter storms or cold snaps break records, the public is increasingly interested in knowing if human-induced climate change played a role. Attributing individual extreme weather events to a warming climate is difficult work. Even so, scientists have been making ...
