• Abstract:
  Under contract to the Washington State Department of Transportation, Battelle, Pacific Northwest Division, conducted a re-analysis of dynamic pile driving and impulsive underwater sound data acquired at WA DOT construction projects (Hood Canal Bridge and Friday Harbor Ferry Terminal) to better understand the mechanisms of impulsive sound generation by pile driving in support of efforts to determine the effects of impulsive sound on fish health and behavior. Analysis focused on derivation of statistics from impulsive sound and dynamic pile driving data sets that permitted evaluation of the amount of variability in impulsive sound metrics that might be driven by variability in pile driving mechanics metrics. The energy required to drive a pile at various depths and substrates and an index of the sound energy produced during the pile drives were also compared. These comparisons yielded the conclusion that most of the variability in impulsive sound during driving of a pile can be accounted for by changes the impact hammer operator makes to overcome resistance to increases in pile depth. Thus, it is the operation of an impact hammer in response to changes in substrate, not the substrate itself, that is responsible for changes in impulsive energy metrics during driving of a pile. A recommendation of the study is that any future data acquisition and analysis efforts to improve understanding of linkages between pile driving mechanics and impulsive sound or underwater sound monitoring activities in support of construction activities include hammer stroke data as a basic element of underwater sound data sets.
