This thesis describes the research undertaken for a degree of Master of Science in a retrospective study of airborne remotely sensed data registered in 1990 and 1993, and field captured data of aquatic humus concentrations for ~ 45 lakes in Tasmania. The aim was to investigate and describe the relationship between the remotely sensed data and the field data and to test the hypothesis that the remotely sensed data would establish further evidence of a limnological corridor of change running north-west to south- east. The airborne remotely sensed data consisted of data captured by the CSIRO Ocean Colour Scanner (OCS) and a newly developed Canadian scanner, a compact airborne spectrographic imager (CASI). The thesis investigates the relationship between the two kinds of data sources. The remotely sensed data was collected with the OCS scanner in 1990 (during one day) and with both the OCS and the CASI in 1993 (during three days). The OCS scanner registers data in 9 wavelength bands between 380 nm and 960 nm with a 10-20 nm bandwidth, and the CASI in 288 wavelength bands between 379.57 nm and 893.5 nm (ie. spectral mode) with a spectral resolution of 2.5 nm. The remotely sensed data were extracted from the original tapes with the help of the CSIRO and supplied software and digital sample areas (band value means) for each lake were subsequently extracted for data manipulation and statistical analysis. Field data was captured concurrently with the remotely sensed data in 1993 by lake hopping using a light aircraft with floats. The field data used for analysis with the remotely sensed data were the laboratory determined g440 values from the 1993 water samples collated with g440 values determined from earlier years. No spectro-radiometric data of the lakes, data of incoming irradiance or ancillary climatic data were captured during the remote sensing missions. The sections of the background chapter in the thesis provide a background to the research both in regards to remote sensing of water quality and the relationship between remotely sensed spectral data and water quality parameters, as well as a description of the Tasmanian lakes flown. The lakes were divided into four groups based on results from previous studies and optical parameters, especially aquatic humus concentrations as measured from field captured data. The four groups consist of the ‘green” clear water lakes mostly situated on the Central Plateau, the ‘brown” highly dystrophic lakes in western Tasmania, the ‘corridor” lakes situated along a corridor of change lying approximately between the two lines denoting the Jurassic edge and 1200 mm isohyet, and the ‘eastern, turbid” lakes make up the fourth group. The analytical part of the research work was mostly concerned with manipulating and analysing the CASI data because of its higher spectral resolution. The research explores methods to apply corrections to this data to reduce the disturbing effects of varying illumination and atmospheric conditions. Three different methods were attempted. In the first method two different standardisation formulas are applied to the data as well as ‘day correction” factors calculated from data from one of the lakes, Lake Rolleston, which had data captured for all three days of the remote sensing operations. The standardisation formulas were also applied to the OCS data. In second method an attempt to reduce the effects of the atmosphere was performed using spectro-radiometric captured in 1988 for one of the lakes flown, Great Lake. All the lake sample data were time normalised using general irradiance data obtained from the University of Tasmania and the sky portion as calculated from Great Lake upwelling irradiance data was then subtracted. The last method involved using two different band ratios to eliminate atmospheric effects. Statistical analysis was applied to the data resulting from the three methods to try to describe the relationship between the remotely sensed data and the field captured data. Discriminant analysis, cluster analysis and factor analysis using principal component analysis (pea) were applied to the remotely sensed data and the field data. The factor scores resulting from the pca were regressed against the field collated data of g440 as were the values resulting from last method. The results from the statistical analysis of the data from the first method show that the lakes group well (100%) against the predetermined groups using discriminant analysis applied to the remotely sensed CASI data. Most variance in the data are contained in the first factor resulting from pca regardless of data manipulation method. Regression of the factor scores against g440 field data show a strong non- linear relationship and a one-sided linear regression test is therefore considered an inappropriate analysis method to describe the dataset relationships. The research has shown that with the available data, correction and analysis methods, and within the scope of the Masters study, it was not possible to establish the relationships between the remotely sensed data and the field measured parameters as hoped. The main reason for this was the failure to retrieve remotely sensed lake signatures adequately corrected for atmospheric noise for comparison with the field data. This in turn is a result of the lack of detailed ancillary information needed to apply available established methods for noise reduction - to apply these methods we require field spectroradiometric measurements and environmental information of the varying conditions both within the study area and within the time frame of capture of the remotely sensed data.

For this report, four municipal services provided by the City of Lakeland were studied. The environmental impact of these services was discussed. Recommendations were made for solutions to problems found. It was found that the water supply services has on deleterious impact on the environment. Hydrogen sulfide occasionally found in the water supply gives the latter objectionable odor and taste. Installation of a centralized water treatment plant with aeration facilities for hydrogen sulfide removal was recommended for resolution of the problem. The waste water treatment plant removes 91% of the BOD5 and the suspended solids in the plant influent. The plant effluent and dried sludge are used for irrigation and fertilization in local agricultural enterprises. It was concluded that this service has a beneficial impact on the environment. It was determined that the electric power supply service has one deleterious impact on the environment. Sulfur dioxide emitted from five power generating units results in higher than allowable ground level concentrations. Several recommendations were made for resolution of the problem. Taller stacks were recommended for all five units. Burning lower sulfur content fuel oil was recommended for three of the units. Installation of an ammonia scrubbing system for sulfur dioxide removal was recommended for the other two units. Sanitary landfill disposal of solid waste collected by the city has two potentially deleterious impacts on the environment. Available land area may be quickly exhausted. Water runoff may leach undesirable materials out of buried refuse and contaminate ground water supplies. Incinerations of Lakeland's solid waste in one of the city's power generating unites was recommended as the solution to the problem. As follow-up to this report, a discussion has been held with city officials concerning the potential sulfur dioxide problem.

Canadians have developed a vocabulary of regionalism, a cultural shorthand that divides Canada into easily-described spaces: the Arctic, the Prairies, the Maritimes, and Central Canada, for example. But these artificial divisions obscure the history of edge places whose identity is drawn from more than one region. The region north of Prince Albert, Saskatchewan, is a place on the edge of the boreal forest whose self-representations, local history, and memorials draw heavily on a non-prairie identity. There, the past is associated with the forest in contrast to most Canadians' understanding of Saskatchewan as flat, treeless prairie. This dissertation presents the history of the north Prince Albert region within a framework that challenges common Saskatchewan and Canadian stereotypes. Through deep-time place history, layers of historical occupation in the study region can be compared and contrasted to show both change and continuity. Historical interpretations have consistently separated the history of Saskatchewans boreal north and prairie south, as if the two have no history of interchange and connection. Using edge theory, this dissertation argues that historical human occupation in the western interior found success in the combination of prairie and boreal lifeways.<p> First Nations groups from both boreal forest and open plain used the forest edge as a refuge, and to enhance resilience through access to resources from the other ecosystem. Newcomer use of the prairie landscape rebranded the boreal north as a place of natural resources to serve the burgeoning prairie market. The prairies could not be settled if there was not also a nearby and extensive source for what the prairies lacked: timber and fuel. Extensive timber harvesting led to deforestation and the rise of agriculture built on the rhetoric of mixed farming, not King Wheat. The mixed farming movement tied to landscape underscored the massive internal migrations from the open prairies to the parkland and forest edge.<p> Soldier settlement, long viewed as a failure, experienced success in the north Prince Albert region and gave a model for future extensive government-supported land settlement schemes. South-to-north migration during the 1920s was based on a combination of push and pull factors: drought in the Palliser Triangle; and a strengthening northern economy built on cordwood, commercial fishing, freighting, prospecting and fur harvesting, as well as mixed farming. The economy at the forest edge supported occupational pluralism, drawing subsistence from both farm and forest, reflecting the First Nations model. As tourism grew to prominence, the Saskatchewan dual identity of prairie/forest led to the re-creation of the north Prince Albert region as a new vacationland, the Playground of the Prairies. The northern forest edge drew thousands of migrants during the Great Depression. Historical analysis has consistently interpreted this movement as frantic, a reactionary idea without precedent. Through a deep-time analysis, the Depression migrations are viewed through a new lens. The forest edge was a historic place of both economic and cultural refuge and resilience predicated on the Saskatchewan contrast of north and south.
