“…These particles comprise a carrier substance mixed together with a commercially available fluorescent dye, pigment (e.g. Harvey et al 1989;Black et al 2004a, b;McComb & Black 2005) or other signature. Ventura et al (2001), for example, explored the utility of polystyrene plastic beads embedded with a magnetic powder.…”

“…McComb & Black (2005), for instance, used tracer manufactured with an equivalent particle size distribution (assuming quartz spheres) based on the settling velocity of the native sediment from the study site. Where it can be independently confirmed that grain size and density are correct, settling velocity can also be used in a diagnostic fashion to highlight any departures in settling velocity between the tracer and native sand due to shape differences.…”

“…These can include careful emplacement by divers (e.g. McComb & Black 2005), ice encapsulation methods (in which the tracer admixture is entombed in a weighted ice block), remotely operated bottles or chambers lowered from a ship (Ingle 1966;White 1987), or barge dumps for very large experiments (Louisse et al 1986;White 1998). Sprinkling the tracersediment admixture represents perhaps the best method of tracer injection onto a seabed (e.g.…”

New European environmental legislation such as the Shellfish and Habitats Directives, together with the more recent Water Framework Directive, are driving new and fresh approaches to sediment management. Regional authorities, environment protection agencies and consultants are increasingly being required to adopt a holistic, system-wide appreciation of sediment flux in aquatic systems. Increasingly, and necessarily, there is a need to describe sediment (and contaminant) transport pathways on dynamically variable and spatially distributed scales rather than at single point localities. 'Particle tracking', or as it is also known 'particle' or 'sediment tracing', providing certain assumptions are satisfied, offers a practical methodology for the assessment of transport pathways of a variety of sediments across wider temporal and spatial scales, and is available for silts, sands, granules, pebbles and cobbles. Although not a new technique, particle tracking has experienced a resurgence of interest and application by geologists, hydrologists and oceanographers principally as a result of the arrival of new, innovative manufacturing and measurement technologies. These have overcome previous limitations presented by the method, and have also provided a foundation for silt tracking that previously did not exist. The purpose of this paper is to provide an overview of the particle tracking methodology in the modern context, with a bias towards the practicalities of conducting a tracking experiment. We present a detailed summary of the factors and considerations involved in conducting tracking studies, including an assessment of tolerance limits on synthetic tracers and the importance of appropriate sampling strategies. In addition, we highlight the principal technical limitations of the method. We summarise the historical background regarding the use of the particle tracking method outlining the dominance of studies on sand transport and the paucity of silt tracking studies, and draw attention to some of the potential areas of application of this innovative approach.

“…It is a relatively straightforward, practical methodology which involves the introduction of particulate tracers into the environment (water body, sewer, beach etc.) labelled with one or more signatures in order that they may be unequivocally identified following release [1,2]. Measurable and uniquely identifiable signatures have in the past included the use of radioactive tracers [3,4] and Rare Earth elements [5], fluorescent coated sands [6], fluorescent silts [7][8][9].…”

Abstract. Source control i.e. the reduction of contamination from upstream or diffuse sources, is a critical element in any management plan for contaminated waterways. If source control measures are not successfully implemented, then a situation exists in which contamination will continue through time, and the cleanup of waterway segments becomes increasingly problematic. To provide greater understanding of the issues surrounding source control, it is essential to have some knowledge of contaminant sources and transport pathways of contaminated particulates. In port areas a plethora of factors interact to control contaminant transport pathways. These include: rain and river flow; tidal circulation, surface waves and wind drift, and temporally changing water column stratification. Particle tracking offers a practical means to map the transport pathways of contaminated sediments under these collective influences. This paper introduces a new and novel "dual signature" tracer product, and describes the particle tracking technique on a practical level through a study example in the Lower Duwamish Waterway, Washington, USA.
