Vertical Transport of Sediment from Muddy Buoyant River Plumes in the Presence of Different Modes of Interfacial Instabilities
… deposition processes from sediment laden buoyant river plumes in deltaic regions. The goal is to experimentally examine the effects of various physical phenomena influencing the rate at which sediment is removed from the plume. Previous laboratory and field measurements have suggested that, at …

Quantifying phytoplankton biomass and sediment in river plumes along the Agulhas Bank using remotely sensed data with deep learning techniques
River plumes play a major role in land-sea connectivity by providing essential nutrients, sediment, and organic matter to marine environments, and maintaining ecosystem function and habitat structure. Phytoplankton communities' reliance on riverine nutrient deposition to build up their biomass and …

The sediment, river plume, and inner shelf variability in a bay with multiple fluvial inputs
Small mountainous rivers deliver considerable sediment loading to the coastal ocean and play a disproportionate role in marine sediment deposition globally. Discharge in these rivers is often driven by short episodic events and they typically deliver sediment to energetic coastal environments where …

Lake Michigan Tributary Characteristics, Nutrient Loading Trends, and River Plume Dynamics
… by evaluating the dynamics of tributaries and river plumes. Analysis focused on answering the following questions: (1) How do hydrologic characteristics of Lake Michigan tributaries vary historically and in comparison to each other; (2) How do nutrient concentrations vary episodically and …

The interaction of two coastal plumes and its effect on the transport of Alexandrium fundyense
… understanding of the interactions between river plumes is essential to our understanding of this problem. The rest of this thesis intends to contribute to the understanding of these plume interactions and their effect on the transport of A. fundyense. Mixing between two interacting river …

Physical controls on copepod aggregations in the Gulf of Maine
… address this mechanism in the context of coastal river plumes and salinity fronts. One chapter describes the characteristics and variability of coastal freshwater and salinity fronts using a historical dataset and a realistic numerical model. The seasonal variability of freshwater is tied in part …

Satellite indices of fluvial influence in coastal waters
… in coastal environments. The covariance between riverine delivery of optically active constituents and the corresponding optical variability in neighboring coastal waters for the Mississippi and Orinoco Rivers is documented. From this work, satellite-based indices of fluvial influence (IFI), are …

Environmental influences on banana shrimps of the Sofala Bank, Mozambique Channel
… that the shelf circulation, structure and river plumes are strongly influenced by the highly energetic o_shore eddy activity. A biophysical, individual-based model (IBM) coupled to the ROMS was developed for early life stages of banana shrimps on the Sofala Bank. The IBM uses spawning …

Three-Dimensional Modelling of Lake Ontairo Hydrodynamics Near Port Hope and in the Upper St Lawrence River
… Conservation Authority (CRCA) and the Ganaraska River Source Protection Agency (GRSPA) jurisdictions respectively, be protected from contaminants released into the surrounding waters through the delineation of Intake Protection Zones (IPZs). Toward these objectives, the Estuary and Lake Computer …

Spatial and Temporal Variability of Particulate and Chromophoric Dissolved Organic Matter Absorption in the Northern Gulf of Mexico
… Analysis of the Mississippi and Atchafalaya River plumes took place on board the RIV Pelican on two separate cruises. MagMix-1 occurred from May 1 to May 8, 2008 and corresponded to the highest discharge periods for both rivers for 2008; MagMix-11 took place October 31 to November 6, 2008 and …

Identification and characterisation of submesoscale activity over the continental shelf in the Bay of Biscay
… activity developing in the vicinity of the Loire River. A 10-year dataset (2003-2013) was explored and satellite ocean colour images revealed a spatial variability in the surface chlorophyll-α distribution. In this context, several events on daily, seasonal and interannual scales were selected and …

Estimating the water quality condition of river and lake water in the Midwestern United States from its spectral characteristics
… for water quality retrieval in Midwestern rivers and lakes. In the first part of this study, the spectral measurements collected using a hand-held spectrometer as well as water quality observations for the Wabash River and its tributary the Tippecanoe River in Indiana were used to develop …
