The damping ratio has recently been used to indicate the relative internal oil thickness within slicks observed in synthetic aperture radar (SAR) imagery. However, there exists no well-defined and evaluated methodology for calculating ratio. In this study, we review prior work regarding outline its theoretical practical aspects. We show that most often yields values differ, some cases significa...

The 2010 Deepwater Horizon oil spill resulted in the accidental release of millions barrels of crude oil into the Gulf of Mexico. Photoinduced toxicity following coexposure to ultraviolet (UV) radiation is one mechanism by which polycyclic aromatic hydrocarbons (PAHs) from oil spills may exert toxicity. Mahi-mahi (Coryphaena hippurus), an important fishery resource, have positively buoyant, tra...

Several oil spill simulation models exist in the literature, which are used worldwide to simulate evolution of an slick created from marine traffic, petroleum production, or other sources. These may range simple parametric calculations advanced, new-generation, operational, three-dimensional numerical models, coupled meteorological, hydrodynamic, and wave forecasting high-resolution with high p...

On October 6, 2002, M/V GOTIA, carrying 163 metric tons of fuel oil in her fuel tanks, rammed into the Emirgan Pier in the Bosporus. One of the fuel tanks started leaking oil in to the Bosporus. The ship continued its passage and finally anchored when it reached the Marmara Sea where the leaking tank was repaired. Following the accident, the strong surface current, rapidly transported the oil s...

A new field method for tar quantification was used at Coal Oil Point (COP), California to study the mechanisms transporting oil/tar from the nearby COP natural marine hydrocarbon seep field. This method segregates tar pieces into six size classes and assigns them an average mass based on laboratory or direct field measurements. Tar accumulation on the 19,927m(2) survey area was well resolved sp...

ABSTRACT Marine oil spill incidents create concerns about human health risks, particularly in nearshore locations such as beaches used for recreation. To improve the timeliness of risk estimates during an spill, we need to expand modelling capacity chemicals (OSCs) from predictions chemical bulk measurements Total Petroleum Hydrocarbons (TPH) individual concentrations more toxic Polycyclic Arom...

The visual appearance of oil spills at sea is often used as an indicator spilled properties, state and slick thickness. These appearances the properties that are associated with them reviewed in this paper. estimator thickness thin slicks, thinner than a rainbow sheen (<3 µm). Rainbow sheens have strong physical explanation. Thicker slicks (e.g., >3 µm) not correlated given appearance. At...

We conducted a series of roller tank incubations with surface seawater from the Green Canyon oil reservoir, northern Gulf of Mexico, amended with either a natural oil slick (GCS-oil) or pristine oil. The goal was to test whether bacterial activities of natural surface water communities facilitate the formation of oil-rich marine snow (oil snow). Although oil snow did not form during any of our ...

To better understand the impact of the Deepwater Horizon (DWH) incident on commercially and ecologically important pelagic fish species, a mahi-mahi spawning program was developed to assess the effect of embryonic exposure to DWH crude oil with particular emphasis on the effects of weathering and dispersant on the magnitude of toxicity. Acute lethality (96 h LC50) ranged from 45.8 (28.4-63.1) μ...
