“…However, the peak in BE appears to be a phenomenon occurring in smallscale testing only. Figure 3 -Diagram of the burning efficiency behaviour based on the current investigation and various studies [21,[36][37][38][39][40]. The current data and data from small-scale (Ø 0.1 to 1.1 m pool diameter) [21,36,38,39] fit curve A where the peak in BE is more pronounced for the smaller pools.…”

“…The current data and data from small-scale (Ø 0.1 to 1.1 m pool diameter) [21,36,38,39] fit curve A where the peak in BE is more pronounced for the smaller pools. Curve B is observed across various pool diameters (Ø 0.1 to 9.8 m) [21,[36][37][38]. Other BE data (Ø 0.4 to 1.14 m) [37,40] does not decrease or decrease slightly (and linearly) as a function of the water content, and this behaviour is represented by curve C. Finally, curve D represents data from a meso-scale test in a 1.7 m diameter pool [21].…”

Small-scale experiments were performed in a custom-made laboratory rig to study the in-situ burning (ISB) behaviour for oils that were chemically confined using herders. The burning efficiency, the global mass burning rate and the regression rate are all reported. Two commercially available herding agents (ThickSlick 6535 and OP40) were used to thicken two crude oils (Alaska North Slope (ANS) and Grane), and their respective artificial water-in-oil emulsions. The burning behaviour during ISB was found to be affected by the oil type and weathering degree. However, no dependencies were observed on the burning behaviour regardless of the herder type. The chemical confinement resulted in quantitative lower burning results (burning efficiency, mass burning rate and regression rate) as compared to physical confinement. Scaling dependencies were also found as a function of the oil amount or oil diameter with contrasting qualitative dependencies between the results from experiments with respectively chemical and physical confinement.

“…In situ burning is a countermeasure technology that was first implemented in 1958 along the ice-covered Mackenzie River in Northwest Canada and since then has been used operationally in ice free areas during the 1989 Exxon Valdez oil spill in Alaska and extensively in the 2010 Deepwater Horizon oil spill in the Gulf of Mexico (Beyer et al 2016;Buist, 2004;Hunt, 2009). Burning is a quickly implemented OSR action that requires little infrastructure and, most significantly, is effective, leaving approximately 10% of the original hydrocarbon load (Guenette and Sveum, 1995;Buist, 2004;Buist et al 2013;Fingas, 2016). Burning creates a burned oil residue (BO) that may sink depending on oil characteristics (Fritt-Rasmussen et al 2015).…”

The present study investigates the potential long-term physiological effects on maturing polar cod (Boreogadus saida), an Arctic key species, after an acute exposure (48 h) to environmentally realistic concentrations of either mechanically dispersed oil (MDO), chemically dispersed oil (CDO) or burned oil residues (BO) (N = 58-60 per treatment). Following exposure, fish were monitored in a common tank supplied with clean water for a seven-month period coinciding with the period of reproductive development. Females exposed to BO residues were more frequently found in an earlier phase of gonadal maturation compared to unexposed females while no effects of different oil spill response (OSR) actions were seen in the reproductive development of males. Mechanically and chemically dispersed oil induced a transient short-term reduction in growth in the first week post-exposure. Overall, no significant long-term effects of exposure were seen in growth or mortality. Ultimately, this study provides information for the assessment of population consequences of different OSR actions as part of a net environmental benefit analysis.

“…Undoubtedly, fire size, fuel type, and condition (weathering), as well as environmental conditions, can affect smoke yield. Guénette and Sveum[42] presented some of these factors, specifically slick thickness, the amount of water in the emulsion and the degree of evaporation. Comparison of the PM 2.5 concentrations from our first six sampled burns (average = 69.8 ± 10.0 g PM 2.5 /kg oil c ) with the nine burns done two days later (average = 49.2 ± 10.3 g PM 2.5 /kg oil c )…”

The surface oil burns conducted by the U.S. Coast Guard from April to July 2010 during the Deepwater Horizon disaster in the Gulf of Mexico were simulated by small scale burns to characterize the pollutants, determine emission factors, and gather particulate matter for subsequent toxicity testing. A representative crude oil was burned in ocean-salinity seawater, and emissions were collected from the plume by means of a crane-suspended sampling platform. Emissions included particulate matter, aromatic hydrocarbons, polychlorinated dibenzodioxins/dibenzofurans, elements, and others, the sum of which accounted for over 92% by mass of the combustion products. The unburned oil mass was 29% of the original crude oil mass, significantly higher than typically reported. Analysis of alkanes, elements, and PAHs in the floating residual oil and water accounted for over 51% of the gathered mass. These emission factors, along with toxicity data, will be important toward examining impacts of future spill burning operations.
