Upper Lakes Shipping Ltd. fonds 1955-1990, n.d. (non-inclusive)

In March 1931, Captain Bruce Angus was sent to Sarnia by Gordon C. Leitch, general manager of Toronto Elevators. He was sent to inspect the Sarnian to ensure it was still seaworthy. Leitch was a savvy business man, who had been active in the business community for a number of years. Leitch began his career with a partner in the lumber business. When that went under he moved into graineries and worked for the Winnipeg Wheat Pool for 12 years. After Winnipeg he moved to Toronto, which was closer to his home town of Ridgetown, Ontario. In Toronto Leitch became manager of the Toronto branch of the Canadian Wheat Pool. While managing the wheat pools in Toronto Leitch became aware of huge costs associated with shipping the grains from the praries into the Toronto area. He felt that there was no need for such costs and decided to do something to make them better and cheaper for the business. Originally the grain was loaded onto Lakers that would bring the grain from the praries to Lake Huron and Georgian Bay. It was stored there until needed by the Toronto graineries and then hauled across land by either truck or train. The land journey was the most expensive and the one which Leitch wanted to eliminate. This was a fine plan except for 2 obstacles that were quickly overcome. First of all the Welland canals were not large enough to accommodate the large carriers that were bringing in the grain. This was changing as the expansion and widening of the canals was already underway. The second issue was the lack of storage in Toronto for the grain. The grain elevators had been destroyed by fire in the late 1880s and never replaced. Leitch propsed his company built its own storage elevators along the water front to allow not only for easier access to the grain, and more timely production of products. The elevators would aslo create a reduction in shipping costs and an overall more competitoive price for the customers of the grainery. The company refused, so Leitch went elsewhere to friends and contacts within the grain industry. The elevators were built and Leitch quit his job with the Canadian Wheat Pool and became the general manager of the elevators. Although the elevators were built and ready for storage the next issue was filling them. None of the carriers wanted to do business with Leitch because the competition in Georgian Bay threatened to cancel their contracts if they did. Leitch saw no way around this, but to provide his own transportation. This is when he sent Captain Bruce Angus to scout out potential ships. The ship was purchased for $37,000 and after another $30,000 was spent to fix it up, it was ready for business. The need for transportation and the finding of a seaworthy ship, lead to the beginnings of the Northland Steamship Company. The Sarnian proved to not be enough for the business underway. Leitch decided another ship was necessary. He joined forces with James Norris the owner of the Norris Grain Company. He proposed they join forces to create a more economical means of transportating their products.

Upper Lakes Shipping Ltd. Vessels Scrapbook, 1964-1967, no date

The origins of Upper Lakes Shipping can be traced back to 1931, when Gordon Leitch, the general manager of Toronto elevators, sent Captain Bruce Angus to scout for potential ships that could be used to transport grain. The ship Sarnian was purchased as a result. It soon became apparent that more ships would be needed by the business, and Leitch subsequently partnered with James Norris of the Norris Grain Company, in order to transport their products more economically. The Upper Lakes and St. Lawrence Transportation Company (which later become known as Upper Lakes Shipping), was incorporated in 1932. In 1956, the company bought Port Weller Dry docks. At this point, the company began constructing new vessels designed to meet specific freight and classification needs.

Draft News Release - Great Lakes Water Quality Agreement

A News Release draft to be sent to "100 newspapers, radio and television stations (virtually all those with offices within 20 miles of the Lakes), make them available to the Press Gallery, special interest groups, trade publication and Mayors etc. of Great Lake-side communities". The release discusses the need for an upgrade to "the 1972 Canada-U.S. Great Lakes Water Quality agreement". Within the document, O'Sullivan is quoted that the agreement "should be upgraded to become a treaty with the United States, so that after all the effort which has already been put into tyring to clean up the Great Lakes we the provision which provides for cancellation by either party giving twelve months (notice) to do so". The total report is 61 pages in length.

Wave Height Ano Speotral Transformation In The Shallow Waters Of Kerala Ooast And Their Preoiotion

There are basically two methods for prediction of shallow water waves, viz. the graphical method and the numerical method. The numerical methods are being widely used, now—a—days, because they are fast, accurate and are especially useful when the prediction over a large spatial frame is required. Practically little has been done on the development of numerical models for the prediction of height and spectral transformation of waves as applicable to our coasts. Synchronized deep and shallow water wave measurements which are essential for study of wave transformation are very much lacking for our coasts. Under these circumstances, a comprehensive study of the wave transformation in the shallow waters of our coast was felt very important and is undertaken in the present investigation.

Nutrient dynamics in the two lakes of Kerala, India

Distribution and chemistry of major inorganic forms of nutrients along with physico-chemical parameters were investigated. Surface sediments and overlying waters of the Ashtamudi and Vembanad Lakes were taken for the study, which is situated in the southwest coast of India. High concentrations of dissolved nitrogen and phosphorus compounds carried by the river leads to oxygen depletion in the water column. A concurrent increase in the bottom waters along with decrease in dissolved oxygen was noticed. This support to nitrification process operating in the sediment-water interface of the Ashtamudi and Vembanad Lake. Estuarine sediments are clayey sand to silty sand both in Ashtamudi and Vembanad in January and May. Present study indicates that the sediment texture is the major controlling factor in the distribution of these nutrient forms. For water samples nitrite, inorganic phosphate was high in Vembanad in January and May compared to Ashtamudi. For sediments, enhanced level of inorganic phosphate and nitrite was found in Vembanad during January and May. It had been observed that the level of N and P is more in sediments. A comparative assessment of the Ashtamudi and Vembanad Lake reveals that the Vembanad wetland is more deteriorated compared to the Ashtamudi wetland system

A High Order Finite Volume Scheme for the 2D Shallow Water Equations Including Topography

Inhalt dieser Arbeit ist ein Verfahren zur numerischen Lösung der zweidimensionalen Flachwassergleichung, welche das Fließverhalten von Gewässern, deren Oberflächenausdehnung wesentlich größer als deren Tiefe ist, modelliert. Diese Gleichung beschreibt die gravitationsbedingte zeitliche Änderung eines gegebenen Anfangszustandes bei Gewässern mit freier Oberfläche. Diese Klasse beinhaltet Probleme wie das Verhalten von Wellen an flachen Stränden oder die Bewegung einer Flutwelle in einem Fluss. Diese Beispiele zeigen deutlich die Notwendigkeit, den Einfluss von Topographie sowie die Behandlung von Nass/Trockenübergängen im Verfahren zu berücksichtigen. In der vorliegenden Dissertation wird ein, in Gebieten mit hinreichender Wasserhöhe, hochgenaues Finite-Volumen-Verfahren zur numerischen Bestimmung des zeitlichen Verlaufs der Lösung der zweidimensionalen Flachwassergleichung aus gegebenen Anfangs- und Randbedingungen auf einem unstrukturierten Gitter vorgestellt, welches in der Lage ist, den Einfluss topographischer Quellterme auf die Strömung zu berücksichtigen, sowie in sogenannten \glqq lake at rest\grqq-stationären Zuständen diesen Einfluss mit den numerischen Flüssen exakt auszubalancieren. Basis des Verfahrens ist ein Finite-Volumen-Ansatz erster Ordnung, welcher durch eine WENO Rekonstruktion unter Verwendung der Methode der kleinsten Quadrate und eine sogenannte Space Time Expansion erweitert wird mit dem Ziel, ein Verfahren beliebig hoher Ordnung zu erhalten. Die im Verfahren auftretenden Riemannprobleme werden mit dem Riemannlöser von Chinnayya, LeRoux und Seguin von 1999 gelöst, welcher die Einflüsse der Topographie auf den Strömungsverlauf mit berücksichtigt. Es wird in der Arbeit bewiesen, dass die Koeffizienten der durch das WENO-Verfahren berechneten Rekonstruktionspolynome die räumlichen Ableitungen der zu rekonstruierenden Funktion mit einem zur Verfahrensordnung passenden Genauigkeitsgrad approximieren. Ebenso wird bewiesen, dass die Koeffizienten des aus der Space Time Expansion resultierenden Polynoms die räumlichen und zeitlichen Ableitungen der Lösung des Anfangswertproblems approximieren. Darüber hinaus wird die wohlbalanciertheit des Verfahrens für beliebig hohe numerische Ordnung bewiesen. Für die Behandlung von Nass/Trockenübergangen wird eine Methode zur Ordnungsreduktion abhängig von Wasserhöhe und Zellgröße vorgeschlagen. Dies ist notwendig, um in der Rechnung negative Werte für die Wasserhöhe, welche als Folge von Oszillationen des Raum-Zeit-Polynoms auftreten können, zu vermeiden. Numerische Ergebnisse die die theoretische Verfahrensordnung bestätigen werden ebenso präsentiert wie Beispiele, welche die hervorragenden Eigenschaften des Gesamtverfahrens in der Berechnung herausfordernder Probleme demonstrieren.

A Motion compensated filtering approach to remove sunlight flicker in shallow water images

A common problem in video surveys in very shallow waters is the presence of strong light fluctuations, due to sun light refraction. Refracted sunlight casts fast moving patterns, which can significantly degrade the quality of the acquired data. Motivated by the growing need to improve the quality of shallow water imagery, we propose a method to remove sunlight patterns in video sequences. The method exploits the fact that video sequences allow several observations of the same area of the sea floor, over time. It is based on computing the image difference between a given reference frame and the temporal median of a registered set of neighboring images. A key observation is that this difference will have two components with separable spectral content. One is related to the illumination field (lower spatial frequencies) and the other to the registration error (higher frequencies). The illumination field, recovered by lowpass filtering, is used to correct the reference image. In addition to removing the sunflickering patterns, an important advantage of the approach is the ability to preserve the sharpness in corrected image, even in the presence of registration inaccuracies. The effectiveness of the method is illustrated in image sets acquired under strong camera motion containing non-rigid benthic structures. The results testify the good performance and generality of the approach
