Ocean crust could store many centuries of industrial CO2

Researchers from the University of Southampton have identified regions beneath the oceans where the igneous rocks of the upper ocean crust could safely store very large volumes of carbon dioxide.



Oil spills raise arsenic levels in the ocean

Oil spills can increase levels of toxic arsenic in the ocean, creating an additional long-term threat to the marine ecosystem, according to research published today in the journal Water Research.



Human impacts on ocean chemistry

Numerous studies are documenting the growing effects of climate change, carbon dioxide, pollution and other human-related phenomena on the world's oceans. But most of those have studied isolated sources of pollution.



Plankton plays role in ocean carbon fixation

Carbon fixation by phytoplankton in the open ocean plays a key role in the global carbon cycle but is not fully understood.



Ecosystems under threat from ocean acidification

Acidification of the oceans as a result of increasing levels of atmospheric carbon dioxide could have significant effects on marine ecosystems, according researchers.



Sources of mercury to ocean fish

With concern over mercury contamination of tuna on the rise and growing information about the health effects of eating contaminated fish, scientists would like to know exactly where the pollutant is coming from and how it's getting into open-ocean fish species.



Ocean Optics Spectrometer Detects Liquid Contraband

The spectrometers have been integrated into demo units of the AY01-01 Rapid Liquid Contraband Detector which uses Raman spectrometry to detect a number of liquid and crystal contraband substances.



Ocean Optics' NIRQuest Spectrometer

NIRQuest from Ocean Optics is a fibre optic near-infrared spectrometer easily adaptable for cost-effective on-line process control measurements from 900-2500 nm.



RNA surprise with microbial ocean catch

An ingenious new method of obtaining marine microbe samples while preserving the microbes' natural gene expression has yielded an unexpected boon: the presence of many varieties of small RNAs.



New high-throughput spectrometers from Ocean Optics

Ocean Optics has expanded its Elite Series of high-performance modular spectrometers with the introduction of the Ventana line of high throughput spectrometers.
