Biosurfactant‐assisted recovery and remediation of hydrocarbons from oily sludge using a mobile aerated washing system

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND The oil industry generates oily sludge, the accumulation of which poses a serious environmental problem. Conventional methods require high costs, specialized equipment, and qualified personnel. This waste can be treated using biosurfactants.

Free living and plankton-associated vibrios: assessment in ballast water, harbor areas and coastal ecosystems in Brazil

Frontiers in Microbiology, 2013
Ballast water is a major transport vector of exotic aquatic species and pathogenic microorganisms. The wide-ranging spread of toxigenic Vibrio cholerae O1 from harbor areas has been frequently ascribed to discharge of contaminated ballast water into ...

Method‐dependent differences in zooplankton abundance and size metrics: Microscopy vs. ZooScan

Limnology and Oceanography: Methods, EarlyView.
Abstract Image‐based approaches such as ZooScan are increasingly used for high‐throughput zooplankton monitoring. However, quantitative evaluations of methodological differences relative to conventional microscopy remain limited. In this study, zooplankton abundance and size‐based metrics obtained from microscopy and ZooScan image analysis were ...

Design and Testing of a Minimal Configuration Underwater Micro‐Glider: Automating Lake and Reservoir Monitoring

Journal of Field Robotics, EarlyView.
ABSTRACT Uncrewed underwater vehicles (UUVs) have transformed oceanographic research through autonomous data gathering. Similarly, lake and other aquatic research can potentially be automated and transformed. However, UUVs would need to be smaller, lighter, less complex, and cheaper than currently available to make them more practical and user‐friendly

The Return of the Allis Shad (Alosa alosa) to the Lower Navigable Reaches of the Seine: Locks Play a Role

River Research and Applications, EarlyView.
ABSTRACT In France, it is estimated that shads (Alosa spp.) have lost 69% of their historical range, mainly due to disrupted river connectivity. After an absence of one century, signs of their return in the Seine River have been recorded over the past two decades: adult and juvenile specimens have been caught by anglers or recorded at video‐counting ...

Not all calcite ballast is created equal: differing effects of foraminiferan and coccolith calcite on the formation and sinking of aggregates [PDF]

, 2014
Correlation between particulate organic carbon (POC) and calcium carbonate sinking through the deep ocean has led to the idea that ballast provided by calcium carbonate is important for the export of POC from the surface ocean.

Bibliometric review of ballast water management within the framework of the circular economy

Cleaner Water
The implementation of the Ballast Water Management Convention (BWMC) has prompted a rapid growth in global research on ballast water management. However, the relationship between ballast water management and circular economy (CE) principles, as well as ...
