“…As the oil/residue attached to the sediment eventually sinks, it can be buried in the seafloor sediment (Bandara et al, 2011). Oilsediment interactions in marine systems include formation of oil-suspended particulate matter aggregates (OSAs), partitioning of oil droplets onto suspended particulate matter, and association of oil components with marine snow and with fecal pellets.…”

“…Oilsediment interactions in marine systems include formation of oil-suspended particulate matter aggregates (OSAs), partitioning of oil droplets onto suspended particulate matter, and association of oil components with marine snow and with fecal pellets. OSAs can remove up to 65% of the oil released into the marine systems (Bandara et al, 2011). Dissolved oil components with low water solubility readily partition onto settling particles, preferentially those composed of organic carbon, soot, or black carbon, and sink with these particles (Adhikari et al, 2015).…”

ABSTRACT. Crude oil is a complex mixture of many thousands of mostly hydrocarbon and nitrogen-, sulfur-, and oxygen-containing compounds with molecular weights ranging from below 70 Da to well over 2,000 Da. When this complex mixture enters the environment from spills, ruptures, blowouts, or seeps, it undergoes a continuous series of compositional changes that result from a process known as weathering. Spills of petroleum involving human activity generally result in more rapid input of crude oil or refined products (diesel, gasoline, heavy fuel oil, and diluted bitumens) to the marine system than do natural processes and urban runoffs. The primary physicochemical processes involved in weathering include

“…The term “oil‐mineral aggregate (OMA)” was first used by Lee et al () to describe the observations made in both field and laboratory experiments when “fine‐grained sediment and oil combine to form microaggregates.” Since then, the term OMA has been extensively used in several other published studies that focus on these oil‐mineral interactions. A few later studies have also occasionally used the term “oil‐sediment aggregate (OSA)” to refer to OMA (Bandara et al, ; Cai et al, ), while other studies have used the term “oil‐suspended particulate matter aggregates (OSA)” (Gong et al, ; Loh et al, ; Sun & Zheng, ). Recently, the term “oil‐particle aggregate (OPA)” has become a preferred term to refer to microscopic aggregates (Fitzpatrick et al, ; Zhao et al, ).…”

“…Several researchers have attempted to create computer models that can generate robust predictions of OPA formation and transport. Early models utilized inputs such as oil content, sediment load, and environmental conditions and focused on simulating the amount of OPAs that will form (Bandara et al, ; Danchuk & Willson, ; Khelifa et al, ; Sterling et al, ). The recently developed A‐DROP model has the capability to predict the amount of oil trapped in OPAs (Zhao et al, ).…”

“…The recently developed A‐DROP model has the capability to predict the amount of oil trapped in OPAs (Zhao et al, ). This model uses a new conceptual framework for predicting oil‐particle coagulation efficiency, which is based on an improved version of other established methods (Bandara et al, ; Hill et al, ; Sterling et al, ) that are used to model the effects of oil stabilization by particles, particle hydrophobicity, and oil‐particle size ratio on OPA formation. A‐DROP is generic model, which was developed with a goal to model oil interactions with either organic or inorganic particles.…”

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.
