Abstract	The Hibernia platform began drilling for oil on November 17th, 1997 in the Atlantic Ocean off the coast of Newfoundland. Measurements of organic and inorganic chemicals occurred in both 1995 and 1998 to determine if this drilling process resulted in a significant sediment change In the ocean floor surrounding the drill site. Statistical analysis and summary of the change in sediment chemistry data collected from the Hibernia Gravity Based Structure (GBS) were released in 1999 by Jacques Whitford Environment Ltd. St. John's, Newfoundland. The objective of this practicum is to more thoroughly examine these data collected before and after the Hibernia drilling process began and to determine whether the introduction of the GBS platform resulted in changes in the concentration of various chemicals in the surrounding sediment. This procedure involved the modification of existing statistical tests to accommodate for the asymmetrical nature of the data as well as existing longitudinal and spatial correlations. Combined data test results of this practicum do not in fact differ significantly from those reported in 1999 by Jacques Whitford Environment Ltd.
