  • Marine Recreation in the Desolation Sound Region of British Columbia
    MARINE RECREATION IN THE DESOLATION SOUND REGION OF BRITISH COLUMBIA by William Harold Wolferstan B.Sc., University of British Columbia, 1964 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF ARTS in the Department of Geography @ WILLIAM HAROLD WOLFERSTAN 1971 SIMON FRASER UNIVERSITY December, 1971 Name : William Harold Wolf erstan Degree : Master of Arts Title of Thesis : Marine Recreation in the Desolation Sound Area of British Columbia Examining Committee : Chairman : Mar tin C . Kellman Frank F . Cunningham1 Senior Supervisor Robert Ahrens Director, Parks Planning Branch Department of Recreation and Conservation, British .Columbia ABSTRACT The increase of recreation boating along the British Columbia coast is straining the relationship between the boater and his environment. This thesis describes the nature of this increase, incorporating those qualities of the marine environment which either contribute to or detract from the recreational boating experience. A questionnaire was used to determine the interests and activities of boaters in the Desolation Sound region. From the responses, two major dichotomies became apparent: the relationship between the most frequented areas to those considered the most attractive and the desire for natural wilderness environments as opposed to artificial, service- facility ones. This thesis will also show that the most valued areas are those F- which are the least disturbed. Consequently, future planning must protect the natural environment. Any development, that fails to consider the long term interests of the boater and other resource users, should be curtailed in those areas of greatest recreation value. iii EASY WILDERNESS . Many of us wish we could do it, this 'retreat to nature'.

Exploration of the “New World” was driven by national interests – in western Canada, principally British interests – as well as a thirst for new goods for commerce. During the earliest phases of colonial occupation in British Columbia, First Nations were often seen as gatekeepers to furs, food, and other provisions sought by newcomers (Fisher 1992).

  • Estuarine and Tidal Currents in the Broughton Archipelago
    Estuarine and Tidal Currents in the Broughton Archipelago M.G.G. Foreman1*, D.J. Stucchi1, Y. Zhang2 and A.M. Baptista2 1Institute of Ocean Sciences, Fisheries and Oceans Canada, Sidney BC V8L 4B2 2Oregon Health and Science University, Beaverton, OR U.S.A. [Orginal manuscript received 2 August 2005; in revised form 11 October 2005] ABSTRACT Current meter observations, Conductivity-Temperature-Depth (CTD) profiles, and river discharges are combined with two numerical models to understand better the estuarine and tidal circulation in the Broughton Archipelago, a complex region of islands, channels, and fiords that has become a primary location for salmon farms in British Columbia. Though tidal currents are strong in many sub-regions, the primary transport mecha- nisms in the archipelago are the estuarine flows resulting from river and glacial runoff, and the near-surface cur- rents that arise from strong winds. The harmonic finite element model, TIDE3D, is shown to reproduce the barotropic tidal currents with reasonable accuracy, but unlike other regions of the British Columbia coast where an extensive archive of historical observations has permitted a diagnostic calculation of average seasonal flows, sparse and noisy CTD observations did not allow a similar computation here. In order to simulate these back- ground flows, the prognostic finite volume model, ELCIRC, was initialized with a smoothed version of these same historical temperature and salinity fields and forced with tides and river discharge. Though the near-surface flows were reproduced with acceptable accuracy, the estuarine and tidal flows at depth were found to be much too weak as a result of numerical dissipation arising from the Eulerian-Lagrangian time stepping.

Bryan Kinney Supervisor Associate Professor Eugene McCann Internal Examiner Professor Department of Geography James LeBeau External Examiner Professor Emeritus, Department of Criminology Southern Illinois University, Carbondale Date Defended/Approved: June 04, 2014 ii Partial Copyright Licence iii Abstract Crime patterns differ across different geographical areas. However, much of the explanations for these differences explicitly focus on urban population areas. The result is that rural areas have been neglected. The current work seeks to explain rural concentrations of crime with an emphasis on violent crime through the use of an alternative to crime rates: a crime location quotient. Data was gathered from the British Columbia Policing Jurisdiction Crime Trends, 2000 – 2009 (BCPJ) and includes the raw counts of both property and violent offending from the Uniform Crime Reporting 2 (UCR2) Survey, Canadian Centre for Justice Statistics, Statistics Canada (N=140). A comparison between crime rates and location quotients suggests that, within British Columbia, rural areas appear to specialize in violent offending.

    Possible Factors Contributing to the Low Productivity of the 2000 Brood Year Pink Salmon (Oncorhynchus gorbuscha) in the Broughton Archipelago, B.C. Canada. Ian V. Williams, Cornelis Groot and Lynda Walthers An Independent Report Submitted to The David Suzuki Foundation by I. V. Williams Consulting Ltd. Nanaimo, B.C. 2 Possible factors contributing to the low productivity of the 2000 brood year Pink Salmon (Oncorhynchus gorbuscha) that migrate through the Broughton Archipelago, B.C. Canada. Ian V. Williams 1, Cornelis Groot2 and Lynda Walthers3 Abstract: Pink salmon (Oncorhynchus gorbuscha) that migrate through the Broughton Archipelago, both as adults and juveniles, had a very poor return in 2002. Less than two fish returned for every 100 spawners counted in 2000. Two unusual events were associated with this low productivity. The observed number of spawners in the study area rivers in 2000 was 3.63 million, higher than any other year on record and a severe epizootic of sea lice (Lepeophtheirus salmonis) was observed in 2001 in the juvenile pink population rearing in and around the near-shore areas of the Broughton Archipelago. The Broughton area is considered a very good nursery area for juvenile pink salmon due to extensive shallow near-shore areas. A review of pink salmon biology is presented. Pink salmon fry production from 12 watersheds in the study area in 2001 was estimated at 47.5 million using a habitat model to estimate spawning capacity. This represents an overall egg to fry survival of 2.2%, which is low but not devastating. There were no observed environmental impacts common to all 12 watersheds, other than overcrowding, which could have contributed to the overall low productivity for the area populations.
