Sensors, Vol. 19, Pages 5176: Marine Oil Slick Detection Based on Multi-Polarimetric Features Matching Method Using Polarimetric Synthetic Aperture Radar Data
In this study, two cases of Radarsat-2 Fine mode quad-polarimetric synthetic aperture radar datasets are exploited to detect a well-known oil seep area that collected over the Gulf of Mexico using the same research area, sensor, and time. A novel oil spill detection scheme based on a multi-polarimetric features model matching method using spectral pan-similarity measure (SPM) is proposed. A multi-polarimetric features curve is generated based on optimal polarimetric features selected using Jeffreys–Matusita distance considering its ability to discriminate between thick and thin oil slicks and seawater. The SP...

Sensors, Vol. 22, Pages 1431: Multidimensional Minimum Euclidean Distance Approach Using Radar Reflectivities for Oil Slick Thickness Estimation
Wehn The need for oil spill monitoring systems has long been of concern in an attempt to contain damage with a rapid response time. When it comes to oil thickness estimation, few reliable methods capable of accurately measuring the thickness of thick oil slick (in mm) on top of the sea surface have been advanced. In this article, we provide accurate estimates of oil slick thicknesses using nadir-looking wide-band radar sensors by incorporating both C- and X-frequency bands operating over calm ocean when the weather conditions are suitable for cleaning operations and the wind speed is very low (<3 m/s). We d...

A Year After a Deadly Disaster, Fears Grow About the Danger of Crude Oil Shipped By Rail
MoreNew York Appeals Court Upholds Bans on FrackingStates Confront Worries About Fracking, QuakesThe Seismic Link Between Fracking and EarthquakesWhen 21-year-old mother Kahdejah Johnson was told two years ago that she’d secured a spot at the Ezra Prentice Homes, a quiet housing project in Albany, she felt confident she’d found a stable home to raise her newborn son. With its manicured lawns and tidy beige row houses, the Ezra Prentice Homes are a far cry from the crumbling housing projects of large cities. “When people come into town they’re like ‘These are your projects? These are condos!...

Airborne ultraviolet imaging system for oil slick surveillance: oil–seawater contrast, imaging concept, signal-to-noise ratio, optical design, and optomechanical model
The airborne ultraviolet imaging system, which assesses oil slick areas better than visible and infrared optical systems, was designed to monitor and track oil slicks in coastal regions. A model was built to achieve the upwelling radiance distribution of oil-covered sea and clean seawater, based on ...

Sensors, Vol. 17, Pages 1837: Discrimination of Oil Slicks and Lookalikes in Polarimetric SAR Images Using CNN
ai An Oil slicks and lookalikes (e.g., plant oil and oil emulsion) all appear as dark areas in polarimetric Synthetic Aperture Radar (SAR) images and are highly heterogeneous, so it is very difficult to use a single feature that can allow classification of dark objects in polarimetric SAR images as oil slicks or lookalikes. We established multi-feature fusion to support the discrimination of oil slicks and lookalikes. In the paper, simple discrimination analysis is used to rationalize a preferred features subset. The features analyzed include entropy, alpha, and Single-bounce Eigenvalue Relative Difference (SERD) in th...

Refined use of AISA band-differences for oil slick identification beyond brightness contrast reversal under sunglint
Marine oil slicks show brighter or darker than surrounding oil-free seawater under different sunglint, which can be observed by satellite optical sensors. Although this has been interpreted using a critical angle concept and simulated using the Cox-Munk model, it has not been demonstrated in high ...

Effective recovery of oil slick using the prepared high hydrophobic and oleophilic Fe3O4 magnetorheological fluid
Publication date: Available online 31 January 2020Source: Colloids and Surfaces A: Physicochemical and Engineering AspectsAuthor(s): Feng Tian, Jian-feng Zhou, Chun-lei Shao, Hong-bo Wu, Liang HaoAbstractMagnetorheological fluids (MRFs) have the excellent comprehensive properties and have widespread applications in lubrication, sealing, vibration reduction and wastewater treatment. When MRFs are used to recover oil from water, the Fe3O4 magnetic nanoparticles (MPs) in MRF are coated by a surfactant which has good hydrophobic and oleophilic properties. After the surfactant fully adsorbs the oil in wastewater, the oil togeth...

Not Just an Oil Slick: How the Energetics of Protein-Membrane Interactions Impacts the Function and Organization of Transmembrane Proteins.
Abstract The membrane environment, its composition, dynamics, and remodeling, have been shown to participate in the function and organization of a wide variety of transmembrane (TM) proteins, making it necessary to study the molecular mechanisms of such proteins in the context of their membrane settings. We review some recent conceptual advances enabling such studies, and corresponding computational models and tools designed to facilitate the concerted experimental and computational investigation of protein-membrane interactions. To connect productively with the high resolution achieved by cognate experimental app...

Sensors, Vol. 18, Pages 641: Experimental L-Band Airborne SAR for Oil Spill Response at Sea and in Coastal Waters
olt Satellite synthetic aperture radar (SAR) is frequently used during oil spill response efforts to identify oil slick extent, but suffers from the major disadvantages of potential long latency between when a spill occurs and when a satellite can image the site and an inability to continuously track the spill as it develops. We show using data acquired with the Uninhabited Aerial Vehicle SAR (UAVSAR) instrument how a low noise, high resolution, L-band SAR could be used for oil spill response, with specific examples of tracking slick extent, position and weathering; determining zones of relatively thicker or more emuls...

The Afterlife of Oil Spills
MoreNavy Seals Capture Rogue Oil Tanker Off Cyprus CoastLibyan Forces Intercept North Korean Tanker with ‘Illicitly Obtained’ OilCrews Try to Contain Oil Spill in Galveston BayOn a shelf at my home, I have a small jar that contains a smear of crude oil. I dug it up on the shore of a small island in Alaska’s Prince William Sound in May of 2009, on a reporting trip for a story about the legacy of the Exxon Valdez oil spill. That crude oil is more than 25 years old now, and its existence is a reminder of just how long lived the effects of a major oil accident can be. Years after the spill has been stopped, a...

Synergistic use of an oil drift model and remote sensing observations for oil spill monitoring.
Abstract In case of oil spills due to disasters, one of the environmental concerns is the oil trajectories and spatial distribution. To meet these new challenges, spill response plans need to be upgraded. An important component of such a plan would be models able to simulate the behaviour of oil in terms of trajectories and spatial distribution, if accidentally released, in deep water. All these models need to be calibrated with independent observations. The aim of the present paper is to demonstrate that significant support to oil slick monitoring can be obtained by the synergistic use of oil drift models and rem...
