Full textAn analytical framework for the simulation and quantitative interpretation of ocean colour data is presented, providing an inverse reflectance algorithm designed for the detection of harmful algal blooms. The adopted framework focuses on establishing quantitative relationships between optically important algal intracellular properties and inherent optical properties (IOPs), such as the absorption and backscattering coefficients, and the resultant effects on remote-sensing reflectance. A principal aim of the study is to establish the determinant variables of the IOPs associated with natural algal assemblages, and provide a means of simulating these IOPs. Algal size is an important determinant of optical properties, and the study demonstrates algal IOP simulation, using equivalent particle size distributions that can be simply parameterised with regard to effective cell diameter. Statistical analyses of causal variability are also conducted on absorption data from a variety of natural algal assemblages, revealing the relative importance of cell size, intracellular Chi a concentration, and accessory pigment complement. An improved understanding of algal angular scattering is regarded as key to the analytical modelling of ocean colour, and the use of two-layered spherical models for the simulation of algal scattering properties is investigated. Preliminary validation of the combined use of the equivalent size and two-layered models indicates that they are capable of adequately simulating the remote-sensing reflectance properties of high biomass bloom waters.

Full textDes fleurs d'eau d'algues néfastes menacent des plans d'eau à travers la planète. Les fleurs d'eau nuisent à la qualité de l'eau, elles sont toxiques pour les êtres-humains et elles menacent la santé et les habitats du biota aquatique. Les fleurs d'eau se répandent dans des plans d'eau ayant une quantité excessive de nutriments, et leur présence est exacerbée par les tendances météorologiques provoquées par les changements climatiques. La plupart des nutriments excessifs dans le Lac Champlain et le Lac Érié sont dus aux effluents d'élevage mais il existe des pratiques d'aménagement du territoire simples que les agriculteurs peuvent mettre en œuvre afin de réduire considérablement les effluents venant de leurs terrains. Malgré le consensus scientifique sur la cause primaire des fleurs d'eau d'algues néfastes ainsi que sur les solutions pour résoudre le problème, les législatures peinent à règlementer les pratiques d'aménagement du territoire des agriculteurs. Cette lutte a surtout lieu car les législatures manquent d'outils juridiques appropriés. Les instruments de politique traditionnels mettent l'accent sur la résolution de différends entre particuliers ou sur la surveillance par le gouvernement de certains acteurs spécifiques. Ils sont ainsi mal adaptés pour faire face aux vastes problématiques environnementales pour lesquelles il est difficile d'identifier une seule source.Pourtant, il y a une lueur d'espoir : la théorie du droit réflexif propose des instruments de politique qui ont pour objectif d'encourager les agriculteurs à s'autoréguler. Ces instruments de politique créent des structures de motivation afin d'aligner les buts des acteurs sur les buts sociétaux, en mettant à profit la puissance du marché et en créant des situations où des pressions sociales pousseront les acteurs à se comporter d'une façon plus socialement souhaitable. Les bassins versants qui les ont mis en œuvre afin de faire face aux effluents d'élevage ont obtenu des résultats globalement encourageants. Dans le cadre de ce projet, je trace le développement des instruments de politique environnementaux en prenant le Lac Champlain et le Lac Érié comme études de cas majeures qui illustrent les incapacités des régimes juridiques traditionnels à faire face à ces vastes problématiques environnementales. Je présente également des stratégies du droit réflexif qui pourraient compenser ces incapacités. Je défends le fait que les régimes juridiques actuels dans les bassins versants du Lac Champlain et du Lac Érié soient incapables de réduire les effluents d'élevage et doivent donc être complétés par des instruments de politique du droit réflexif afin que les législatures progressent dans la lutte contre les fleurs d'eau d'algues néfastes.

Cyanobacteria are Gram-negative photosynthetic bacteria capable of producing toxins responsible for morbidity and mortality in humans and domestic animals. Many are capable of forming concentrated blooms that impact the environment by limiting the growth of sub-surface plants and phytoplankton. Harmful algal blooms (HABs) are also capable of producing multiple types of toxins, creating a potential hazard to recreational water users and animals drinking water from or near a bloom. Characterization of HABs is necessary to prevent these human and animal exposures and includes classifying of the type of cyanobacteria present and whether or not they are capable of toxin production, and the exact type of cyanotoxin that is actually present in bloom. Current methods used to classify cyanobacteria and cyanotoxins include microscopy, bioassays, ELISA, PCR, HPLC, and LC/MS. All of these methods, however, have limitations that include time, labor intensity, or cost. Fourier-Transform Infrared Spectroscopy (FTIR) is another potential tool for cyanobacterial classification that is not limited by these factors. To examine the practicality of this method, library screening with default software algorithms was performed on diagnostic samples received at the Kansas State University Veterinary Diagnostic Lab, followed by PCA of samples meeting minimum quality requirements to produce cluster analyses and dendrograms. Both spectrometers and software packages used were successful at distinguishing cyanobacteria from green algae in clean samples with 89.13% agreement. PCA resulted in clear classification of cyanobacteria or green algae demonstrated by a large order of magnitude difference produced by average Euclidian distance dendrograms. While this method is only capable of differentiating cyanobacteria from green algae or other aquatic environmental constituents, its simple, rapid use and low cost make it a beneficial screening tool when coupled with toxin-detection methods to characterize HABs.
