Determination of T90 in the coastal waters near Punta Lobos final report; Informe final sobre determinacion del T90 en las aguas costeras de la region de Punta Lobos

Abstract

The concept of the T--90 in estuarine and coastal waters is reviewed.A mathematical diagnostics model to describe advection,dispersion and bacterial mortality in complex stratified receiving waters is developed and solved using regular perturbation techniques.Four field experiments were designed and executed in the estuarine coastal waters of Punta Lobos,Department of Montevideo,Uruguay.Fluorescent dyes were used to measure dilution.The classic method of counting in the laboratory the number of colony forming units was employed to estimate bacterial concentrations.Drogues and an auxiliary dye were used to facilitate the sailor maneuvers.Three ships were used in the field experiments.Winds,currents,temperature,conductivity,salinity,ph and other parameters were measured in each campaign.Using the measured parameters and mathematical prognostic models the mass of tracer required was calculated on board and subsequently injected jointly with the bacterial population.The experimental data were used to estimate a value of T90 in each scenario.
