Coastal Marine Science Laboratory Manuscript Reports

Permanent URI for this collection

The Royal Roads Military College (RRMC) operated on the current site of Royal Roads University between the years of 1968 and 1995. A number of legacy RRMC research documents remain under the care of RRU, including the Coastal Marine Science Laboratory manuscript reports.

This is a collection of seven research reports that focus on Esquimalt Lagoon and surrounding bodies of water. Research, conducted between the years of 1978 and 1980, looks at effluents, speciation and succession of zooplankton, sediment distribution, red tides, and bottom and sub-bottom surveys.

    Sub-bottom surveys of harbours near Victoria, B.C.
    (2009-06-18T22:29:08Z) Schurer, P.J.
    The coast of Vancouver Island, British Columbia, Canada, is indented by many bays and inlets. Reconnaissance surveys of the bottom and sub-bottom of Victoria Harbour, Esquimalt Harbour, Royal Roads, Pedder Bay, Parry Bay, Becher Bay, Sooke Bay, Sooke Harbour and Sooke Basin are reported. A 3-7 kHz profiler and 105 kHz side scan sonar were used. A more extensive study of Sooke Basin using a better positioning system, one meter coring equipment and divers is also reported.

    Study of sediment distribution in Esquimalt Harbour
    (2009-06-18T22:26:27Z) Baudat, C.; MacFarlane, W.T.; Madill, J.W.
    Descriptive literature dealing with Esquimalt Harbour has always listed it as having a "first-class holding bottom for anchorage" (Forde 9, 1925). The harbour is also the site of an important Canadian Naval Base. The harbour bottom therefore seemed a logical place to focus attention for an initial study by a group from this College with its new emphasis on oceanography. No scientific study, to our knowledge, has been made of the harbour sediments. Comparing bathymetric charts dating back to 1848 indicates the sedimentation is reducing the harbour volume substantially, especially in the upper reaches of the harbour.

    Speciation and succession of zooplankton in Esquimalt Lagoon, BC
    (1979) Brauser, T.; Robinson, M.G.
    The speciation, abundance and seasonal succession of the zooplankton in Esquimalt Lagoon was studied during 1978 and part of 1979. A brief comparison with the zooplankton in adjacent waters was also made. The lagoon is characterized by a low species diversity and a population which is dominated in the spring and early summer by the copepod Acartia clausii and to a lesser extent barnacle cauplii and the cladoceran Podon. Only very low numbers of other species are found at other times of the year. The increase in zooplankton population in the spring coincides with the spring phytoplankton increase together with a warming trend. The decline of the population in July appears to be associated with fish predation, a reduction in fecundity due to temperature and adverse conditions in the sediment which inhibit egg hatching.

    Red tide in Esquimalt Lagoon due to gymnodinium sanguineum hirasaka
    (Nov-1979) Robinson, M.G.; Watanabe, L.N.
    During a 1-year intensive monitoring program of Esquimalt Lagoon, B.C., a red tide occurred in September and October, 1978, involving the non-toxic dinoflagellate Gymnodinium sanguineum. Detailed information is therefore available for the period leading up to, during and following the red tide. A number of factors are considered with respect to their roles in initiating, maintainoing and terminating the bloom, including temperature, salinity, hydrography, light, macro- and micronutrients, competition and predation. It is ocncluded that all phases of the bloom were regulated principally by the availability of inorganic nitrogen, although not all aspects of its development can be explained in these terms.

    Predictions of effluent fields discharged into Royal Roads
    (Aug-1978) Krauel, D.P.
    A method is devised to predict the "worst case" shoreline concentrations in the effluent field discharged from a submerged ocean outfall. Three phases in the dilution process are recognized and are combined into an empirical equation: initial dilution, turbulent diffusion, and decay. Readily obtainable environmental parameters such as wind speed and direction frequency distributions, water current speed and direction frequency distributions, and the density stratification frequency distribution are employed to predict the "worst case" concentrations and their probabilities at selected shoreline locations. The technique is applied to the Royal Roads area, a coastal embayment in the Greater Victoria area in which a sewer outfall already exists and a second outfall is proposed. In order to predict the median shoreline coliform counts for critical locations, the "worst case" values are fitted to a lognormal distribution with a standard deviation which is determined from a limited monitoring program of the existing outfall. Although the errors involved in the calculations are quite large, the technique yields an order of magnitude prediction. The method finds that the existing Royal Roads outfall meets the environmental standard of a shoreline median coliform count not greater than 1000 MPN per 100 ml. The method also predicts that the proposed Portsmouth outfall will be well within the environmental standard.
