Abstract:

This study investigates translocation of particulate carbon and nitrogen from burned and unburned catchments within New Mexico's Valles Caldera National Preserve following severe wildfire. My research questions are: (1) how much carbon and nitrogen is eroded from burned slopes and re-deposited in debris fans? and (2) how do these quantities compare to fluvial export of particulate carbon and nitrogen from nearby unburned catchments? Results indicate that the ~200 kg ha⁻¹ of nitrogen per depositional area on the debris fans represents ~50 to 100 years' worth of atmospheric inputs. In total, 124

Abstract:

Methods for the determination of Polycyclic Aromatic Hydrocarbons (PAHs) associated with suspended participate matter were developed with the aim of determining airborne concentrations and to investigate seasonal trends. Other associate pollutants such as Total Suspended Particulate matter (TSP), Particulate Matter with an equivalent aerodynamic diameter less than 10 micrometres (PM10) and lead concentration were also reviewed to determine trends. Motor vehicle emissions appear to be the source of the PAHs and differences between the types and concentrations of PAHs detected at central busines

Transport of suspended particulate matter (SPM) plays a vital role in controlling large-scale processes related to geophysical flows such as dispersal and sinking of organic matter and contaminants to offshore and deep waters, nutrient cycles, food web stability, morphodynamics and sedimentation in both limnetic and pelagic ecosystems. Although it has been recognized that small-scale microbial processes can introduce substantial differences to the way in which SPM moves in natural waters, the extent to which the attached biological matter affects SPM dynamics is still not well characterized.

Investigating linkages between the compositions of suspended (seston) and benthic particulate matter is important to the understanding of organic matter (OM) cycling and nutrient retention in aquatic systems. We compared the quantity and quality of the truly suspended (TS) and settleable (SB) fractions of seston as well as benthic particulate matter in the tidal freshwater James River, Virginia. The mass of seston and OM was consistently higher in the TS fraction compared to the SB fraction. OM was preferentially retained in the TS fraction relative to seston.

In this study, parameters influencing the adsorption of dispersed oil droplets to suspended particulate matter (SPM) in seawater were investigated.

The chosen parameters of this study were sediment type (carbonate sand, quartz sand and clay) and concentration (5-80 g/L seawater), temperature (5-20 °C) and oil type (two crudes, one condensate and a heavy fuel oil).

Abstract:

Dynamics and properties of sands and suspended particulate matter (SPM) in the Gonwy Estuary were investigated. SPM properties were measured at specific locations over tidal cycles. Floc formation was restricted by increased turbulence at 3 h before low water (LW). At LW, decreased velocities allowed floc formation and partial sedimentation of SPM. At peak velocities c.3h after LW, the mean suspended sediment concentration (SSG) at the surface reached a maximum of 47mgr1 . Particle size increased and effective density decreased due to resuspension of low density, large particles. At high water

Abstract:

The majority of terrestrially derived suspended particulate matter (SPM) is transported to the open ocean by rivers, therefore the river estuary transition zone (RETZ) represents a globally significant boundary separating the riverine and coastal regimes. The RETZ is comprised of the Tidally-Influence River (TIR), found above the limit of salt intrusion and the upper part of the estuary including the Estuarine Turbidity Maximum (ETM). The fate of SPM in the RETZ depends on its physical properties which are likely to be extremely variable in the RETZ which is characterised by large temporal and

Abstract:

Les matières en suspension (MES) sont constituées de colloïdes et particules et sont couramment décrites comme des agrégats hétérogènes formées de phases minérales, organiques et biologiques et possédant une forte réactivité de surface. Cette étude vise à étudier l’évolution de composition spatiale et temporelle des MES de la rivière Moselle (Lorraine, France) et également d’étudier la réactivité des MES vis-à-vis de contaminants métalliques. Les MES ont été collectées à différentes stations le long de la rivière Moselle et selon différents régimes hydriques. Des études microscopiques et macro

Abstract:

O objetivo principal deste trabalho foi avaliar a composição química do material particulado em suspensão na atmosfera na cidade de Limeira/SP, pela técnica de fluorescência de raios X dispersiva em energia (EDXRF). Um amostrador tipo stacker foi utilizado para coletar particulados fino (partículas com diâmetro aerodinâmico entre 2,5 e 10 \'mü\'m) e grosso (partículas maiores que 10 \'mü\'m), utilizando filtros de policarbmüonato de 47 mm de diâmetro e com diâmetros de poro de 0,4 e 8 \'mü\'m, respectivamente. As amostras foram coletadas em 2006 (de janeiro a dezembro), 2008 (de janeiro a abr

Abstract:

La connaissance de la dynamique des matières en suspension (MES) et des turbidités en milieu côtier est un élément clé pour comprendre les écosystèmes marins. Les processus de floculation/défloculation représentent des mécanismes essentiels contrôlant la dynamique des caractéristiques physiques des MES et, par conséquent, leur devenir dans l’environnement. Cette thèse a pour objectif de mieux comprendre la caractérisation des MES et leur variabilité de l’échelle tidale à l’échelle annuelle en mer côtière, en réponse aux différents forçages hydrodynamiques, hydrologiques et biologiques ayant li

This river also carries a large amount of fine sediments to the ocean where fluid mud has been found in the topset and upper foreset layers of the subaqueous delta formed on the mid-shelf. One of the main goals of this dissertation is to describe how turbulence and suspended sediment concentration

Abstract:

<p>This thesis presents predictive models for important variables concerning eutrophication effects in lakes. The keystone is a dynamic phosphorus model based on ordinary differential equations. By calculating mass fluxes of phosphorus into, within and out from a lake, the concentrations of different forms of phosphorus in different compartments of the lake are estimated.</p><p>The dynamic phosphorus model is critically tested and several improvements are presented, including two new compartments for colloidal phosphorus, a sub-model for suspended particulate matter (SPM) and new algorithms fo

Abstract:

<p>This thesis presents models applicable for aquatic ecosystems. Geographical Information Systems (GIS) form an important part of the thesis. The dynamic mass balance models focus on nutrient fluxes, biotic/abiotic interactions and operate on different temporal and spatial scales (site, local, regional and international). The relevance and role of scale in mass balance modelling is a focal point of the thesis.</p><p>A mesocosm experiment was used to construct a model to estimate the nutrient load of phosphorus and nitrogen from net cage fish farming (i.e., the site scale).
