Environmental Science

“Environmental science is the study of all the mechanisms of environmental processes…it examines environmental problems with the goal of contributing to their solution”.
J.M. Moran, M.D. Morgan and J.H. Wiersma. Introduction to Environmental Science, 2nd Ed.

Since its inception, the team at Envirosphere Consultants Limited has been applying our expertise and that of our associates to solve a wide range of environmental problems, naturally from a multidisciplinary perspective. We offer expertise in oceanography, ecology, water chemistry and water quality, botany, environmental science, hydrogeology, zoology, wetlands, sediments, and aquatic and marine biology. We have undertaken and successfully completed a wide range of studies for government and industry, which have added to our understanding of the world around us and of human impacts on it.

Environmental Research & Development Projects

Surficial Sediment Mapping for the Scotian Shelf. Fisheries and Oceans Canada, 2001.

Digitized existing surficial sediment maps for the Scotian Shelf into MapInfo GIS for use in coastal zone management projects carried out by Fisheries and Oceans.

Environmental Assessment Software for DRDC Research Cruises. Defence Research and Development Canada, (DRDC) Atlantic, 2006-2009.

Developed a web-based software tool and database to assist DRDC in completing CEAA environmental assessments for offshore research cruises.

Database of Fish Eggs and Larvae Distributions on the Scotian Shelf and Adjacent Waters. Fisheries and Oceans Canada and Environmental Studies Research Funds. 2003-2004.

Prepared an electronic database of distribution and abundance information on fish eggs and larvae, from literature and re-analysis of research survey data, to be used by researchers and the oil industry as an information source in environmental assessment of offshore projects.

Terrestrial and Intertidal Baseline Surveys for Shore Facilities.

Fundy Tidal Power Demonstration Project, Minas Basin Pulp & Power Co. Ltd. 2008-2009.  Conducted surveys of terrestrial birds, and freshwater and intertidal habitats and wetlands at the site of the shore facility and cable landfall for the tidal power demonstration project.

Marine Mammal and Seabird Surveys, Minas Passage. Minas Basin Pulp & Power Co. Ltd. 2008-ongoing. 

Carried out surveys of marine mammals and seabirds in Minas Passage and adjacent areas to document baseline abundance and species composition. The study results will be used to determine changes resulting from installation of tidal devices in the area.

Water Quality and Oceanographic Surveys, Minas Passage. Minas Basin Pulp & Power Co. Ltd. 2008-2009.  

Oceanographic observations at the site of the tidal energy demonstration project were made throughout the year at the site in 2008-2009 using a combination of water samples and a Seabird CTD equipped with turbidity sensors to measure suspended sediment levels.

Effects of Oil and Remediation on Shoreline Vegetation of the Upper St. Lawrence River. Fisheries and Oceans Canada, Québec Region. 1999-2000.

Measured and compared biomass, size, and species composition of freshwater marsh plants subjected to an experimental oil spill and subsequent remediation.

Underwater Photography and Video Surveys of Minas Passage. Minas Basin Pulp & Power Co. Ltd. & Fundy Ocean Research Centre for Energy. 2008-2009.

Drop-camera surveys of the seabed for interpretation of seabed geology and benthic community distribution, used for site selection for experimental berths and cable routes for Nova Scotia’s tidal power demonstration facility.

Marine Benthic Communities at the Sigguk And Eqqua Blocks, West Greenland. McGregor Geoscience, Bedford, Nova Scotia. 2010.

Interpreted data on benthic communities from sediment samples and bottom photographs as input to survey and environmental assessment reports for a proposed hydrocarbon exploration program by Capricorn Greenland Exploration Limited on the Greenland continental shelf in Baffin Bay.

Benthic and Contaminant Monitoring—Strait of Canso Ocean Disposal Site. Environment Canada. 2004-2005.

Designed monitoring program and carried out sediment sampling for contaminants and toxicology, as well as analysis of benthic invertebrate communities, at the Strait of Canso common user ocean disposal site and in nearby industrialized and reference areas.

Ballast Water Management Guidelines and Database of Marine Invasive Species in Areas of Operations by the Canadian Navy (MARLANT). SNC-Lavalin. 2002-2003.

Reviewed ballast water treatment approaches and invasive species issues, including compilation of a database and regional fact sheets of marine invasive species potentially encountered around the world in Canadian naval operations.

Impacts of the Saint John Ocean Disposal Site on Seabed Animal Communities. Environment Canada. 2001-2002.

Surveyed bottom communities in the vicinity of the Black Point Ocean Disposal site, to determine short- and long-term impacts. The study included statistical design, evaluation of near- and far-field effects on various community parameters, and an overview of recent work and historical changes at the disposal site.
