dAVE sCRUTON - Senior Scientist

Mr. Scruton has 34+ years of experience as research scientist and research manager working with federal and provincial governments and as an environmental consultant.  He has considerable knowledge experience in study and assessment of mercury bioaccumulation in fish in Newfoundland and Labrador, in both natural systems and hydroelectric reservoirs. He was involved in the COMERN (Collaborative Mercury Rersearch network), a NSERC (Natural Sciences and Engineering Research Council of Canada) funded strategic research network.   He has coordinated and conducted a diverse research program on knowledge of relationships between fish and their habitats, effects of human activities on fish and fish habitat, means to mitigate and compensate for habitat losses, and application of knowledge to development of models and tools for predictions, impact assessment, and habitat development.  He led and managed a number of large national and international programs on fish habitat research and conducted collaborative research with the utility sector, pulp and paper companies, fishing industry, and transportation sector.  He was, and still is, active in academia as an adjunct professor and supervisor of graduate students.  He has authored over 200 scientific and technical publications including: 70+ in scientific journals, 40+ technical reports, 10+ special publications, seven book chapters, 70+ conference proceedings, and 20 + popular articles or internal reports.  Since joining SEM as Senior Scientist, he has assumed project lead on several ongoing environmental effects monitoring programs, fish habitat compensation projects, baseline studies, and has developed a discussion paper on the biological and ecological evolution of hydroelectric reservoirs.

Jason also has participated in a number of field projects including construction and environmental oversight of a fish habitat, stream and water surveys and ice monitoring.

Jason also has accumulated a wide array of skills related to functioning as a Construction Management Representative at Menihek, Bay D’Espoir and other Nalcor facilities.


Crystal Kehoe - Quality Control

Crystal has a Bachelor of Science from Trent University as well as a diploma as a Laboratory Technician from CDI College. Since joining the SEM team November 2010, Crystal has been part of a variety of projects including consultation programs, field sampling and environmental monitoring. She has led and been part of freshwater field studies that involved the collection of water, sediment, benthos, fish and plankton. She has also been included in fish population studies using electofishing equipment. Crystal’s diverse experience also includes organizing and mediating public consultations throughout Newfoundland and Labrador.

In addition to her biological role, Crystal has extensive experience in word processing and database management. Crystal was involved in leading a team responsible for database structuring and word processing for a recent major environmental impact statement. Currently, Crystal is the project manager for the Quality Management System at SEM.



Andrew Roberts works with both environmental and geomatics based project. He has a Bachelor's of Science Degree in Geography, a Master’s Degree in Environmental Science, and a Geographic Information Sciences Diploma from Memorial University of Newfoundland.

The majority of Andrew’s experience is focused on GIS/remote sensing using advanced equipment including: UAVs (fixed wing and rotary), oceanographic systems (singlebeam, multibeam, and sub-bottom sonars), LiDAR, hyperspectral sensors, 360 VR camera, camera stabilization gear, and topographic land surveying equipment.

Andrew’s first major project at SEM was the completion of a research and development (R & D) project which tested commercial UAV operations beyond visible line of sight for the purpose of mapping/monitoring right-of-way vegetation clearing. Most recently, he has finished a one year secondment position with NL Hydro during the construction of the TL-267 transmission line where he focused on real-time GIS mapping for project support and tracking. Other recent highlights include UAV mapping of Voisey's Bay Nickel Mine, UAV mapping of Soldiers Pond Converter Station, bathymetry mapping of the Exploits River, and various environmental work associated with a large fish offset project.


Colin has a Bachelor of Science Degree in Biology from Memorial University and a GIS Applications Specialist post-graduate diploma from the College of the North Atlantic. He has contributed to various projects in the environmental, mining and construction fields focusing mainly on GIS, remote sensing and Unmanned Aerial Vehicles. He also works as a Construction Management Representative on various NL Hydro construction and maintenance projects.

Before joining SEM, he gained valuable experience working on the Emera NL Maritime Link Project as a GIS Technician and Coordinator, as well as conducting a GIS-based asset management project for the Town of St. Anthony, NL.


Mr. Nicolas Lachance is a bilingual geologist with 12 years of broad range experience in mineral exploration geology, and geotechnical civil engineering work. He has completed a Master`s degree in geology at Memorial University in 2015, and a Bachelor’s degree at Université du Québec à Montéal in 2005. He has worked on diverse projects in remote locations across Canada. His experience and education have provided him with a broad range of knowledge in various fields of earth sciences that include environmental geology, geological and surficial mapping, soil mechanics and aggregate analysis. Some of the professional skills he has developed throughout his career include the capacity for analytical thinking, a sense of commitment and dedication to quality, dependability and good communication skills. Recently he has worked as a geotechnical geologist as part of the Lower Churchill transmission line project and for Altius Minerals as an exploration geologist.
