Preliminary investigation on aquatic invasive species of marine and estuarine macrobenthic invertebrates on floating structures in five British Columbia harbours by Lin Lu ( Book )
4 editions published in 2007 in English and held by 44 libraries worldwide
Samples of invertebrate communities on buoys and floating docks at Vancouver, Esquimalt, Namaimo, Port Alberni and Prince Rupert, British Columbia, were obtained in August and September 2005. The purpose of the preliminary survey was to provide baseline data on the taxonomic composition of the invertebrates, with specific reference to possible aquatic invasive species.--Document.
Data report on the distribution and abundance of meiofauna on Roberts Bank, British Columbia ( Book )
2 editions published in 2009 in English and held by 32 libraries worldwide
Estimates of sediment meiofaunal abundance were determined at six sampling transects across the tidal flats of Roberts Bank, British Columbia, between June, 2003 and February, 2004. Transects were positioned perpendicular to the shoreline with 3 transects located north of the Delta port causeway and 3 transects located within the intercauseway region (between the Delta port and Ferry Terminal causeways). These data were collected as part of a larger multidisciplinary project addressing the sensitivity of the Roberts Bank tidal flats to potential changes in wave energy and sediment supply due to climate change.

Examination of factors influencing Nechako River discharge, temperature, and aquatic habitats ( Book )
2 editions published in 2007 in English and held by 13 libraries worldwide
This report assesses temperature and flow management options in the upper and lower Nechako system with reference to the needs of resident and migratory fish species. The efficacy of an existing management scheme is considered as are the possible benefits of developing cold water release capabilities at the Kenney Dam as a means to broaden water management options. If summer temperature targets at Finmoore can be achieved while altering water release timing and volume, the broad interests of many stakeholder groups may be met without forgoing the current temperature benefits to salmon throughout the Nechako basin resulting from the current flow regime. The goals of this manuscript can be summarized as follows: 1. To assess the success of the existing water management scheme in terms of moderating high summer water temperatures in the Nechako upstream of the Stuart confluence. 2. To consider the effects of the existing management scheme on temperatures in the Nechako downstream of the Stuart confluence and to assess the overall effect on sockeye salmon that migrate through the Nechako upstream and downstream of the Stuart confluence. 3. To introduce a model that examines the downstream consequences of possible future release scenarios if a Kenney Dam release facility were constructed. While proposed water release facilities at Kenney Dam may have many positive environmental benefits there is a proven temperature management efficacy to maintaining the release of large volumes of water during the summer period when salmon are in the vicinity. Current temperature targets at Finmoore can be achieved with the release of smaller amounts of cooler water from Kenney Dam but may result in warmer conditions in the lower Nechako and cooler conditions in the upper Nechako compared to conditions under the current temperature management regime. Changes to the existing management protocol must be made with caution and should consider a broad range of environmental and operational factors.
Data report on the distribution and density of two eelgrass species, Zostera marina and Zostera japonica, on Roberts Bank, British Columbia ( Book )
3 editions published in 2006 in English and held by 11 libraries worldwide
Estimates of eelgrass shoot density and biomass were measured at six sampling transects located across the tidal flats of Roberts Bank, British Columbia. Five eelgrass sampling trips took place in June, August, October, and December, 2003 and February 2004. The sampling transects were positioned perpendicular to the shoreline with 3 transects located north of the Deltaport causeway and 3 transects located within the intercauseway region (between the Deltaport and Ferry Terminal causeways). Shoot density and biomass estimates were carried out for two eelgrass species that exist on the tidal flats. These data were collected as part of a larger multidisciplinary project addressing the sensitivity of the Roberts Bank tidal flats to potential changes in wave energy and sediment supply due to climate change.
Bibliography for environmental assessments associated with port developments at Fraser River Delta and Prince Rupert harbour, British Columbia ( Book )
3 editions published in 2009 in English and held by 7 libraries worldwide
This report is a bibliography of both peer reviewed and non peer reviewed literature related to to ecosystems associated with two major port locations: Roberts Bank (Fraser River Delta) and Prince Rupert Harbour. These environments are areas of high ecological value and sensitivity as they represent key choke-points within salmon and shore-bird migration routes. This bibliography is a step towards a state-of-knowledge review of ecosystem processes within the areas of proposed development. The bibliography is divided into two main areas, by author and by subject. The author section is subdivided by location, and the subject section is focused on the Fraser River Delta.--Includes text from document.
Preliminary survey of indigenous, non-indigenous, and cryptogenic benthic invertebrates in Burrard Inlet, Vancouver, British Columbia ( Book )
1 edition published in 2006 in English and held by 2 libraries worldwide
In a preliminary investigation into the presence of non-indigenous invertebrates in Burrard Inlet, Vancouver, British Columbia, qualitative sampling on rocky shores, pilings and floating docks was conducted in July and August 2004. Twenty-nine sites were established, 34 samples were analysed, and 103 different taxa were identified. Data were also obtained on habitat characteristics including substrate type, salinity and temperature. Identification of polychaetes, mussels from four sites, all amphipods isopods and patellogastropods have been confirmed by taxonomic specialists.
A benthic study examining the relationship between sediment properties and faunal groups observed at Sir Edmund Bay, British Columbia ( Book )
1 edition published in 2006 in English and held by 2 libraries worldwide
A benthic sampling survey was carried out in June 2003, at a finfish aquaculture site situated in Sir Edmund Bay located on the northeast shoreline of Broughton Island, Broughton Archipelago, British Columbia. Samples were also collected at reference stations in Penphrase Passage. A Van Veen grab was used to collect benthic organisms and sediment chemistry samples, while a gravity corer was used to collect sediment cores for in situ Total sediment sulphide analysis. Correlations between macrofauna and benthic variables are presented in this report.
