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 ...

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: ...

Measuring carbon dioxide (CO2) along ocean surfaces case study
Customer: Confidential Application: A research team needed to study the levels and variations of one of the major greenhouse gases, carbon dioxide (CO2) along the ocean surfaces. The research team required CO2 analysers to be installed in commercial ocean liners to monitor the “dry” level of CO2 on ocean surfaces as well as the ability to calibrate automatically and accurately ...

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 ...

Why Innovasea is Leading Canada’s Ambitious Ocean Aware Project
In late July Canada’s Ocean Supercluster announced its Ocean Aware project, a $29 million program to develop new technologies to help maritime industries improve operations while lessening their impacts on the environment. Innovasea is leading the ambitious, three-year project, and we couldn’t be more excited about its potential to reimagine some of the ways humans interact with the ...

Algae blooms in Lake Erie: surprising severity raises concerns
Predictions about algae blooms in Lake Erie made earlier suggested that they wouldn’t be too severe, with a potential severity range of 2.5 to 4 on a scale of 1 to 10. However, a recent report has revealed that the situation is more serious than initially ...

`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 ...

Project - Reef Monitoring
We utilise standard survey techniques to provide reliable long-term information on the health of coral reefs Reef Health Surveys We have been monitoring the status of the Bay of Ranobe’s coral reef system since 2004. Our long term surveying programme monitors various ecological parameters across the bay to provide an assessment of coral reef health. The surveys are conducted across five ...

Most UK coastal flooding caused by moderate, not extreme storms
Scientists at the NOC and the University of Southampton have found that the majority of instances of coastal flooding around the United Kingdom in the last 100 years have been due to moderate storm events combined with high spring tides, rather than extreme storms. Researchers have undertaken one of the most detailed assessments of extreme sea level and coastal flooding ever carried out for the ...

Case Study: Liz Bagshaw on the IRC sensors
Our infrared IR’C sensors have been making waves in the world of glacial meltwater monitoring. Glacial environments are key indicators of global warming and climate change. They’re also home to a diverse range of microorganisms. Both of these need to be quantified and monitored, but doing this isn’t easy because of the cold, remote environments in which they are found. To ...

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 ...

Managing oceans with sound science
Management of marine resources for sustainable development needs local capacity for science, particularly in the Pacific region. Those who care about environmental damage and its effects on the health and welfare of communities tend to focus on land-based threats. That is where harm can be most easily observed, and where its causes — from agricultural pesticides to industrial air pollution ...

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 ...

Warming rivers endanger aquatic life, research unveils
Rivers across the globe are experiencing unprecedented rates of warming and loss of oxygen, endangering aquatic life. Recent findings from a Penn State-led study reveal that among almost 800 rivers examined, a staggering 87% have been warming, while 70% have been losing oxygen. For areas like the American South, the future could be even bleaker. Projections indicate that within seven decades, ...
