Capsule Resume

John Christian has been an aquatic biologist with LGL St. John's for over eighteen years during which time he has conducted numerous studies for both government and industry. He has participated in numerous projects for petroleum industry clients, specializing on issues related to marine invertebrates and fish. John has contributed to the environmental assessments of numerous oil and gas activities off Newfoundland and Labrador, and Nova Scotia. These contributions have focused mostly on marine fish and invertebrates. Activities have included seismic surveys, geohazard surveys, vertical seismic profiling, delineation and exploratory drilling, and production drilling for numerous oil and gas industry clients. John has also been a key contributor to numerous Strategic Environmental Assessments (SEA) prepared for the Canada−Newfoundland and Labrador Offshore Petroleum Board. He has participated in a number of marine Environmental Effects Monitoring (EEM) programs, the longest being the 1991−1997 program at Bull Arm, Trinity Bay, Newfoundland during the construction of the Hibernia gravity-based drilling/production platform. As project biologist/field leader, his responsibilities during this period included the collection of contaminant indicator data on sediments, mussels and flounder in Bull Arm, analysis and interpretation of data, and reporting of results. John was project biologist/field leader in a National Energy Board Environmental Studies Research Funds (ESRF) study designed to examine the effects of seismic energy on snow crab. It was the first study of its type in Canada. He was also involved in a recent Fisheries and Oceans Canada study of the effects of seismic on egg-carrying female snow crabs. He was an author of a review of the effects of underwater sound on marine invertebrates and fish for the American Petroleum Institute. Most recently, John has been involved in projects that have caused coastal marine HADD and subsequently require compensation strategies and plans that satisfy DFO. Planned compensation works associated with these projects include the construction and long-term monitoring of marine artificial reefs. John has authored a report for Fisheries and Oceans that comprehensively reviewed the habitat requirements of marine invertebrates in the Northwest Atlantic, particularly those occurring in Newfoundland and Labrador waters. In addition to his marine experience, John has also conducted numerous freshwater projects which have included field data collection, data analyses and interpretation, and report production. As with the marine projects, the foci of these freshwater studies have been fish and invertebrate species.
