Inference of Tidal Elevation in Shallow Water Using a Vessel-Towed Acoustic Doppler Current Profiler
Vessel-towed acoustic Doppler current profilers (ADCPs) have been widely used to measure velocity profiles. Since the instrument is usually mounted on a catamaran floating on the surface, previous studies have used the water surface as the reference level from which the vertical coordinate for the velocity profile is defined. However, because of the tidal oscillation, the vertical coordinate th...

observations is proposed. Previous-t@ acquisition conditions are considered along with simultaneous ones. Independently of internal systems, location and misalignment, the auxiliary systems to acquisition determine the accuracy range of the current velocity profiles. Simultaneous-toacqu isition navigation conditions provide the physically descriptive weight (or reliability) of significance for ...
متن کاملSuspended particulate matter transport of polycyclic aromatic hydrocarbons in the lower Columbia River and its estuary
Analysis of suspended particulate material (SPM) collected from the Columbia River and its estuary in 2007– 2008 revealed the ubiquitous presence of polycyclic aromatic hydrocarbons (PAHs) from several distinct sources. The two dominant ones were: (1) a suite of non-alkylated, three to five-ringed compounds derived from high temperature combustion and (2) perylene, a compound of diagenetic orig...
متن کاملMutagenicity and genotoxicity of suspended particulate matter in the Seine river estuary.
Highly mutagenic compounds such as some PAHs have been identified in surface waters and sediments of the Seine river estuary. Suspended particulate matter (SPM) represents a dynamic medium that may contribute to the exposure of aquatic organisms to toxic compounds in the water column of the estuary. In order to investigate major sources of mutagenic contaminants along the estuary, water samples...
متن کاملFlux of Particulate Matter in the Tidal Marshes and Subtidal Shallows of the Rhode River Estuary
There was a net influx of suspended particulate matter to the uppermost part of the Rhode River estuary during the several years of this study. Most of the influx was due to episodic discharges of suspended sediment from the watershed during heavy rains. In contrast, tidal exchange of particulate matter was not related to rainstorms. Sediment composition data and historical records indicate tha...
