NOMES dispersion study site, showing the proposed dredging site (stippled box) where test particles were released, sampling area (line portion), generalized path of drogues, current meter locations (black dots numbered 1-6 and A and B) and comparative sample stations (stars), where D3~6 represents D + 3 sample 6, etc. Experimental procedure Tracer particles Fluorescent dyes such as rhodamine B were deemed inadequate for a dredge plume simu- lation, since dye does not exhibit the settling characteristics of natural sedimentary particles. Thus a tracer was used composed of particles which exhibited settling characteristics similar 911.
