The volume of sediments deposited from November 1988 to August 1990 was 

 expected to add to the existing disposal mound without increasing the height and size of the 

 mound detectable with bathymetry. This prediction was based on results from a bathymetric 

 and REMOTS® survey conducted in January 1987 which suggested that material may spread 

 more in a deeper site such as MBDS in comparison to shallow water sites (Bajek et al. 

 1987). It was also felt that positioning problems during the disposal operations may have 

 caused inaccurate and widely spaced placement of dredged material inhibiting the formation 

 of a dredged material mound. While this was the expected result, there was some 

 anticipation that a mound may have been successfully formed since the 1988 survey. The 

 formation of a mound at a deep water site such as MBDS (depths > 25 m and < 150 m) 

 would mean capping of dredged material is also feasible.
