Manitoba Hydro's diversion of the Churchill River at Southern Indian Lake, part of a multi-million dollar hydro-electric development in northern Manitoba, will have extensive economic, social and environmental implications. The impact that the project may have on slush-ice formation in the estuary at the Port of Churchill is one such implication. Previous studies have suggested that reduced flows on the lower Churchill River may alleviate the problem of slush-ice formation which physically terminates the navigation season at Churchill. A reduction in the formation of slush ice would make feasible an average tow week extension of the navigation season. The primary objective of this study was to assess the effect of the Churchill River diversion on the length of the navigation season at the Port of Churchill. A secondary objective was to determine the relationship between the physical variables (slush ice and sedimentation) and the economic variable (insurance coverage) that influence the length of the navigation season. A field trip to Churchill was made in late July, 1973 to collect data. Interviews with hydrologists, ice observers, and National Harbours Board personnel were conducted at this time. In the data analysis, October Churchill River discharges and meteorological data on climatic factors were correlated with dates of Churchill harbour closure due to slush ice for the period 1928-1972......

The Churchill Falls are a second Niagara. They are situated in the interior of Labrador, about 200 miles from the nearest point of the open Atlantic coast, and about 225 miles north of the Gulf of St.Lawrence (figure 1-1). [...]

The purpose of this paper is to study how the conservatism have changed in the conservative party in the United Kingdom and what influence the party leader seems to have over the party ideology. To answer this purpose an idea analysis is used and a material consisting of election manifestos from three periods of the party´s history (Churchill, Thatcher and Cameron) but even political biographies of the leaders. The result shows some difference between the manifestos and the leaders, but even some similarities. One difference, but also a similarity over time, is the view of a cooperation in Europe. Churchill’s manifestos are positive to a cooperation between nations in Europe, Thatcher and Cameron there manifestos share the same skeptics against a further European cooperation. One similarity over time is the support for family as one of the central values in the country. About the leaders and the manifestos there are some similarities, but also some difference between them. Example of similarities are Churchill and the manifestos support full employment, Thatcher and the manifestos support aim on inflation. Cameron is personally divvied in his relation to trade unions and so is the manifestos.  One difference between Churchill and the manifestos is that Churchill accepted capital punishment, but the manifestos never take a stand in this issue. Thatcher and the manifestos don’t share the same view on homosexuality rights, Thatcher is negative and the manifestos not even take a stand. Cameron´s view on privatization is unown, but the manifestos are positive.

Climate change can affect northern aquatic systems causing changes in the composition of resident species through either evolutionary or ecological processes. Rock pools near Churchill, Manitoba, Canada provide an ideal study system for studying the effect of environmental change in a metacommunity context, since salinity of the pools has increased significantly over the past quarter century, and dispersal between habitats is important in this landscape. I used a field experiment to study how zooplankton communities respond to increased salinity with two levels of dispersal limitation and three seasonal levels. I found that experimental zooplankton communities shifted from freshwater to more saline communities after a time lag of three weeks, and that highly connected pools became more similar to saline control communities faster than isolated pools. Moreover, freshwater communities manipulated later in the season changed faster to saline communities. This study highlights the metacommunity concept as a useful tool for studying environmental change. / This thesis has already been submitted to Graduate Program Services in hard copy and approved, however I was advised that I could upload it for electronic distribution as well.
