“…Ultraviolet epifluorescent microscopy has proved useful for characterizing the fine structure of oil-mineral aggregates. The size distribution of dispersed oil droplets and OMAs has been defined by light and UV epi-fluorescence microscopy [2,5,11,13], and the volume of OMA-associated oil has been quantified [23]. In all cases, the accurate determination of the size distribution of oil droplets and oil-mineral aggregates based on microscopic image analysis requires multiple view fields, high resolution microphotographs and an efficient dataprocessing computer program.…”

This paper describes recent advances in microscopic analysis for quantitative measurement of oil droplets. Integration of a microscope with bright-field and ultraviolet epi-fluorescence illumination (excitation wavelengths 340-380 nm; emission wavelengths 400-430 nm) fitted with a computer-controlled motorized stage, a high resolution digital camera, and new image-analysis software, enables automatic acquisition of multiple images and facilitates efficient counting and sizing of oil droplets. Laboratory experiments were conducted with this system to investigate the size distribution of chemically dispersed oil droplets and oil-mineral aggregates in baffled flasks that have been developed for testing chemical dispersant effectiveness. Image acquisition and data processing methods were developed to illustrate the size distribution of chemically dispersed oil droplets, as a function of energy dissipation rate in the baffled flasks, and the time-dependent change of the morphology and size distribution of oil-mineral aggregates. As a quantitative analytical tool, epifluorescence microscopy shows promise for application in research on oil spill response technologies, such as evaluating the effectiveness of chemical dispersant and characterizing the natural interaction between oil and mineral fines and other suspended particulate matters.

“…This natural mechanism contributes to dispersion of spilled oil because it enhances stability of oil droplets in the water column. More recently, it has been suggested that formation of oil mineral aggregates (OMA) may play a major role in the natural cleaning of oiled shorelines and may be the basis for the development of oil spill countermeasure technologies (Bragg, Prince, Harner, & Atlas, 1994;Bragg & Yang, 1993;, 1999J ez equel, Merlin, & Lee, 1999;Kepkay, Bugden, Lee, & Stoffyn-Egli, 2002;Khelifa, Stoffyn-Egli, Hill, & Lee, 2002, 2003a, 2003bLee et al, 2003, Lee, Lunel, Wood, Swannell, & Stoffyn-Egli, 1997Le Floch et al, 2002;Muschenheim & Lee, 2002;Omotoso, Munoz, & Mikula, 2002;Owens, 1999;, 1994Payne, Clayton, & Kirstein, 2003, 1989, 1999Wood, Lunel, Baily, Lee, & Stoffyn-Egli, 1997). Nevertheless, little is known about the influence of water salinity and clay type on OMA formation.…”

“…The natural formation of OPAs in situ was first confirmed by microscopic observations that were made following the Sea Empress spill in 1996 (Lee et al, ). OPAs were also observed to play a significant role in the remediation of experimentally oiled beach plots that were part of the Svalbard shoreline field trials (Lee et al, ; Sergy et al, ). In addition to marine environments, OPAs have also been observed to form in freshwater systems impacted by oil spills (Fitzpatrick et al, ).…”

Crude oil that is spilled in marine environments often interacts with suspended sediments to form residues that can impact the recovery of the affected nearshore ecosystems. When spilled oil and sediment interact, they can form either small microscopic aggregates, commonly referred to as oil‐particle aggregates, or large macroscopic agglomerates, referred to as sediment‐oil agglomerates or sediment‐oil mats. Although these different sized oil‐sediment residues have similar compositions, they are formed under different conditions and have different fates in nearshore environments; the goal of this review is to synthesize our current understanding of these two types of residues. We believe that researchers who focus solely on studying either microscopic aggregates or macroscopic agglomerates could benefit from understanding the research findings available in the other field. In this study, we compare and contrast various processes that control the formation, fate, and impacts of these two types of residues in nearshore environments and point out some of the knowledge gaps in this field. Additionally, these residues have been referred to by many names in the past, leading to confusion and misconceptions at times. In this effort, we recommend a uniform nomenclature to distinguish them based on their physical size. Our overall aim is to bridge the gap between microscopic and macroscopic oil‐sediment residue literature to foster a robust exchange of ideas, which we believe can lead to the development of efficient strategies for managing oil spills that affect nearshore environments.
